Track Selection
|
|
---------------
|
|
|
|
``--alang=<languagecode[,languagecode,...]>``
|
|
Specify a priority list of audio languages to use. Different container
|
|
formats employ different language codes. DVDs use ISO 639-1 two-letter
|
|
language codes, Matroska, MPEG-TS and NUT use ISO 639-2 three-letter
|
|
language codes, while OGM uses a free-form identifier. See also ``--aid``.
|
|
|
|
.. admonition:: Examples
|
|
|
|
``mpv dvd://1 --alang=hu,en``
|
|
Chooses the Hungarian language track on a DVD and falls back on
|
|
English if Hungarian is not available.
|
|
``mpv --alang=jpn example.mkv``
|
|
Plays a Matroska file in Japanese.
|
|
|
|
``--slang=<languagecode[,languagecode,...]>``
|
|
Specify a priority list of subtitle languages to use. Different container
|
|
formats employ different language codes. DVDs use ISO 639-1 two letter
|
|
language codes, Matroska uses ISO 639-2 three letter language codes while
|
|
OGM uses a free-form identifier. See also ``--sid``.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``mpv dvd://1 --slang=hu,en`` chooses the Hungarian subtitle track on
|
|
a DVD and falls back on English if Hungarian is not available.
|
|
- ``mpv --slang=jpn example.mkv`` plays a Matroska file with Japanese
|
|
subtitles.
|
|
|
|
``--aid=<ID|auto|no>``
|
|
Select audio track. ``auto`` selects the default, ``no`` disables audio.
|
|
See also ``--alang``. mpv normally prints available audio tracks on the
|
|
terminal when starting playback of a file.
|
|
|
|
``--sid=<ID|auto|no>``
|
|
Display the subtitle stream specified by ``<ID>``. ``auto`` selects
|
|
the default, ``no`` disables subtitles.
|
|
|
|
See also ``--slang``, ``--no-sub``.
|
|
|
|
``--vid=<ID|auto|no>``
|
|
Select video channel. ``auto`` selects the default, ``no`` disables video.
|
|
|
|
``--ff-aid=<ID|auto|no>``, ``--ff-sid=<ID|auto|no>``, ``--ff-vid=<ID|auto|no>``
|
|
Select audio/subtitle/video streams by the FFmpeg stream index. The FFmpeg
|
|
stream index is relatively arbitrary, but useful when interacting with
|
|
other software using FFmpeg (consider ``ffprobe``).
|
|
|
|
Note that with external tracks (added with ``--sub-file`` and similar
|
|
options), there will be streams with duplicate IDs. In this case, the
|
|
first stream in order is selected.
|
|
|
|
``--edition=<ID|auto>``
|
|
(Matroska files only)
|
|
Specify the edition (set of chapters) to use, where 0 is the first. If set
|
|
to ``auto`` (the default), mpv will choose the first edition declared as a
|
|
default, or if there is no default, the first edition defined.
|
|
|
|
|
|
Playback Control
|
|
----------------
|
|
|
|
``--start=<relative time>``
|
|
Seek to given time position.
|
|
|
|
The general format for absolute times is ``[[hh:]mm:]ss[.ms]``. If the time
|
|
is given with a prefix of ``+`` or ``-``, the seek is relative from the start
|
|
or end of the file.
|
|
|
|
``pp%`` seeks to percent position pp (0-100).
|
|
|
|
``#c`` seeks to chapter number c. (Chapters start from 1.)
|
|
|
|
.. admonition:: Examples
|
|
|
|
``--start=+56``, ``--start=+00:56``
|
|
Seeks to the start time + 56 seconds.
|
|
``--start=-56``, ``--start=-00:56``
|
|
Seeks to the end time - 56 seconds.
|
|
``--start=01:10:00``
|
|
Seeks to 1 hour 10 min.
|
|
``--start=50%``
|
|
Seeks to the middle of the file.
|
|
``--start=30 --end=40``
|
|
Seeks to 30 seconds, plays 10 seconds, and exits.
|
|
``--start=-3:20 --length=10``
|
|
Seeks to 3 minutes and 20 seconds before the end of the file, plays
|
|
10 seconds, and exits.
|
|
``--start='#2' --end='#4'``
|
|
Plays chapters 2 and 3, and exits.
|
|
|
|
``--end=<time>``
|
|
Stop at given absolute time. Use ``--length`` if the time should be relative
|
|
to ``--start``. See ``--start`` for valid option values and examples.
|
|
|
|
``--length=<relative time>``
|
|
Stop after a given time relative to the start time.
|
|
See ``--start`` for valid option values and examples.
|
|
|
|
``--speed=<0.01-100>``
|
|
Slow down or speed up playback by the factor given as parameter.
|
|
|
|
If ``--audio-pitch-correction`` (on by default) is used, playing with a
|
|
speed higher than normal automatically inserts the ``scaletempo`` audio
|
|
filter.
|
|
|
|
``--loop=<N|inf|force|no>``
|
|
Loops playback ``N`` times. A value of ``1`` plays it one time (default),
|
|
``2`` two times, etc. ``inf`` means forever. ``no`` is the same as ``1`` and
|
|
disables looping. If several files are specified on command line, the
|
|
entire playlist is looped.
|
|
|
|
The ``force`` mode is like ``inf``, but does not skip playlist entries
|
|
which have been marked as failing. This means the player might waste CPU
|
|
time trying to loop a file that doesn't exist. But it might be useful for
|
|
playing webradios under very bad network conditions.
|
|
|
|
``--pause``
|
|
Start the player in paused state.
|
|
|
|
``--shuffle``
|
|
Play files in random order.
|
|
|
|
``--chapter=<start[-end]>``
|
|
Specify which chapter to start playing at. Optionally specify which
|
|
chapter to end playing at. Also see ``--start``.
|
|
|
|
``--playlist=<filename>``
|
|
Play files according to a playlist file (Supports some common formats. If
|
|
no format is detected, it will be treated as list of files, separated by
|
|
newline characters. Note that XML playlist formats are not supported.)
|
|
|
|
You can play playlists directly and without this option, however, this
|
|
option disables any security mechanisms that might be in place. You may
|
|
also need this option to load plaintext files as playlist.
|
|
|
|
.. warning::
|
|
|
|
The way mpv uses playlist files via ``--playlist`` is not safe against
|
|
maliciously constructed files. Such files may trigger harmful actions.
|
|
This has been the case for all mpv and MPlayer versions, but
|
|
unfortunately this fact was not well documented earlier, and some people
|
|
have even misguidedly recommended use of ``--playlist`` with untrusted
|
|
sources. Do NOT use ``--playlist`` with random internet sources or files
|
|
you do not trust!
|
|
|
|
Playlist can contain entries using other protocols, such as local files,
|
|
or (most severely), special protocols like ``avdevice://``, which are
|
|
inherently unsafe.
|
|
|
|
``--chapter-merge-threshold=<number>``
|
|
Threshold for merging almost consecutive ordered chapter parts in
|
|
milliseconds (default: 100). Some Matroska files with ordered chapters
|
|
have inaccurate chapter end timestamps, causing a small gap between the
|
|
end of one chapter and the start of the next one when they should match.
|
|
If the end of one playback part is less than the given threshold away from
|
|
the start of the next one then keep playing video normally over the
|
|
chapter change instead of doing a seek.
|
|
|
|
``--chapter-seek-threshold=<seconds>``
|
|
Distance in seconds from the beginning of a chapter within which a backward
|
|
chapter seek will go to the previous chapter (default: 5.0). Past this
|
|
threshold, a backward chapter seek will go to the beginning of the current
|
|
chapter instead. A negative value means always go back to the previous
|
|
chapter.
|
|
|
|
``--hr-seek=<no|absolute|yes>``
|
|
Select when to use precise seeks that are not limited to keyframes. Such
|
|
seeks require decoding video from the previous keyframe up to the target
|
|
position and so can take some time depending on decoding performance. For
|
|
some video formats, precise seeks are disabled. This option selects the
|
|
default choice to use for seeks; it is possible to explicitly override that
|
|
default in the definition of key bindings and in slave mode commands.
|
|
|
|
:no: Never use precise seeks.
|
|
:absolute: Use precise seeks if the seek is to an absolute position in the
|
|
file, such as a chapter seek, but not for relative seeks like
|
|
the default behavior of arrow keys (default).
|
|
:yes: Use precise seeks whenever possible.
|
|
:always: Same as ``yes`` (for compatibility).
|
|
|
|
``--hr-seek-demuxer-offset=<seconds>``
|
|
This option exists to work around failures to do precise seeks (as in
|
|
``--hr-seek``) caused by bugs or limitations in the demuxers for some file
|
|
formats. Some demuxers fail to seek to a keyframe before the given target
|
|
position, going to a later position instead. The value of this option is
|
|
subtracted from the time stamp given to the demuxer. Thus, if you set this
|
|
option to 1.5 and try to do a precise seek to 60 seconds, the demuxer is
|
|
told to seek to time 58.5, which hopefully reduces the chance that it
|
|
erroneously goes to some time later than 60 seconds. The downside of
|
|
setting this option is that precise seeks become slower, as video between
|
|
the earlier demuxer position and the real target may be unnecessarily
|
|
decoded.
|
|
|
|
``--hr-seek-framedrop=<yes|no>``
|
|
Allow the video decoder to drop frames during seek, if these frames are
|
|
before the seek target. If this is enabled, precise seeking can be faster,
|
|
but if you're using video filters which modify timestamps or add new
|
|
frames, it can lead to precise seeking skipping the target frame. This
|
|
e.g. can break frame backstepping when deinterlacing is enabled.
|
|
|
|
Default: ``yes``
|
|
|
|
``--index=<mode>``
|
|
Controls how to seek in files. Note that if the index is missing from a
|
|
file, it will be built on the fly by default, so you don't need to change
|
|
this. But it might help with some broken files.
|
|
|
|
:default: use an index if the file has one, or build it if missing
|
|
:recreate: don't read or use the file's index
|
|
|
|
.. note::
|
|
|
|
This option only works if the underlying media supports seeking
|
|
(i.e. not with stdin, pipe, etc).
|
|
|
|
``--load-unsafe-playlists``
|
|
Load URLs from playlists which are considered unsafe (default: no). This
|
|
includes special protocols and anything that doesn't refer to normal files.
|
|
Local files and HTTP links on the other hand are always considered safe.
|
|
|
|
Note that ``--playlist`` always loads all entries, so you use that instead
|
|
if you really have the need for this functionality.
|
|
|
|
``--loop-file=<N|inf|no>``
|
|
Loop a single file N times. ``inf`` means forever, ``no`` means normal
|
|
playback. For compatibility, ``--loop-file`` and ``--loop-file=yes`` are
|
|
also accepted, and are the same as ``--loop-file=inf``.
|
|
|
|
The difference to ``--loop`` is that this doesn't loop the playlist, just
|
|
the file itself. If the playlist contains only a single file, the difference
|
|
between the two option is that this option performs a seek on loop, instead
|
|
of reloading the file.
|
|
|
|
``--ab-loop-a=<time>``, ``--ab-loop-b=<time>``
|
|
Set loop points. If playback passes the ``b`` timestamp, it will seek to
|
|
the ``a`` timestamp. Seeking past the ``b`` point doesn't loop (this is
|
|
intentional). The loop-points can be adjusted at runtime with the
|
|
corresponding properties. See also ``ab_loop`` command.
|
|
|
|
``--ordered-chapters``, ``--no-ordered-chapters``
|
|
Enabled by default.
|
|
Disable support for Matroska ordered chapters. mpv will not load or
|
|
search for video segments from other files, and will also ignore any
|
|
chapter order specified for the main file.
|
|
|
|
``--ordered-chapters-files=<playlist-file>``
|
|
Loads the given file as playlist, and tries to use the files contained in
|
|
it as reference files when opening a Matroska file that uses ordered
|
|
chapters. This overrides the normal mechanism for loading referenced
|
|
files by scanning the same directory the main file is located in.
|
|
|
|
Useful for loading ordered chapter files that are not located on the local
|
|
filesystem, or if the referenced files are in different directories.
|
|
|
|
Note: a playlist can be as simple as a text file containing filenames
|
|
separated by newlines.
|
|
|
|
``--chapters-file=<filename>``
|
|
Load chapters from this file, instead of using the chapter metadata found
|
|
in the main file.
|
|
|
|
``--sstep=<sec>``
|
|
Skip <sec> seconds after every frame.
|
|
|
|
.. note::
|
|
|
|
Without ``--hr-seek``, skipping will snap to keyframes.
|
|
|
|
``--stop-playback-on-init-failure=<yes|no>``
|
|
Stop playback if either audio or video fails to initialize. Currently,
|
|
the default behavior is ``no`` for the command line player, but ``yes``
|
|
for libmpv. With ``no``, playback will continue in video-only or audio-only
|
|
mode if one of them fails. This doesn't affect playback of audio-only or
|
|
video-only files.
|
|
|
|
Program Behavior
|
|
----------------
|
|
|
|
``--help``
|
|
Show short summary of options.
|
|
|
|
``-v``
|
|
Increment verbosity level, one level for each ``-v`` found on the command
|
|
line.
|
|
|
|
``--version, -V``
|
|
Print version string and exit.
|
|
|
|
``--no-config``
|
|
Do not load default configuration files. This prevents loading of both the
|
|
user-level and system-wide ``mpv.conf`` and ``input.conf`` files. Other
|
|
configuration files are blocked as well, such as resume playback files.
|
|
|
|
.. note::
|
|
|
|
Files explicitly requested by command line options, like
|
|
``--include`` or ``--use-filedir-conf``, will still be loaded.
|
|
|
|
Also see ``--config-dir``.
|
|
|
|
``--list-options``
|
|
Prints all available options.
|
|
|
|
``--list-properties``
|
|
Print a list of the available properties.
|
|
|
|
``--list-protocols``
|
|
Print a list of the supported protocols.
|
|
|
|
``--log-file=<path>``
|
|
Opens the given path for writing, and print log messages to it. Existing
|
|
files will be truncated. The log level always corresponds to ``-v``,
|
|
regardless of terminal verbosity levels.
|
|
|
|
``--config-dir=<path>``
|
|
Force a different configuration directory. If this is set, the given
|
|
directory is used to load configuration files, and all other configuration
|
|
directories are ignored. This means the global mpv configuration directory
|
|
as well as per-user directories are ignored, and overrides through
|
|
environment variables (``MPV_HOME``) are also ignored.
|
|
|
|
Note that the ``--no-config`` option takes precedence over this option.
|
|
|
|
``--save-position-on-quit``
|
|
Always save the current playback position on quit. When this file is
|
|
played again later, the player will seek to the old playback position on
|
|
start. This does not happen if playback of a file is stopped in any other
|
|
way than quitting. For example, going to the next file in the playlist
|
|
will not save the position, and start playback at beginning the next time
|
|
the file is played.
|
|
|
|
This behavior is disabled by default, but is always available when quitting
|
|
the player with Shift+Q.
|
|
|
|
``--dump-stats=<filename>``
|
|
Write certain statistics to the given file. The file is truncated on
|
|
opening. The file will contain raw samples, each with a timestamp. To
|
|
make this file into a readable, the script ``TOOLS/stats-conv.py`` can be
|
|
used (which currently displays it as a graph).
|
|
|
|
This option is useful for debugging only.
|
|
|
|
``--idle=<no|yes|once>``
|
|
Makes mpv wait idly instead of quitting when there is no file to play.
|
|
Mostly useful in slave mode, where mpv can be controlled through input
|
|
commands.
|
|
|
|
``once`` will only idle at start and let the player close once the
|
|
first playlist has finished playing back.
|
|
|
|
``--include=<configuration-file>``
|
|
Specify configuration file to be parsed after the default ones.
|
|
|
|
``--load-scripts=<yes|no>``
|
|
If set to ``no``, don't auto-load scripts from the ``scripts``
|
|
configuration subdirectory (usually ``~/.config/mpv/scripts/``).
|
|
(Default: ``yes``)
|
|
|
|
``--script=<filename>``
|
|
Load a Lua script. You can load multiple scripts by separating them with
|
|
commas (``,``).
|
|
|
|
``--script-opts=key1=value1,key2=value2,...``
|
|
Set options for scripts. A script can query an option by key. If an
|
|
option is used and what semantics the option value has depends entirely on
|
|
the loaded scripts. Values not claimed by any scripts are ignored.
|
|
|
|
``--merge-files``
|
|
Pretend that all files passed to mpv are concatenated into a single, big
|
|
file. This uses timeline/EDL support internally. Note that this won't work
|
|
for ordered chapter files.
|
|
|
|
``--no-resume-playback``
|
|
Do not restore playback position from the ``watch_later`` configuration
|
|
subdirectory (usually ``~/.config/mpv/watch_later/``).
|
|
See ``quit_watch_later`` input command.
|
|
|
|
``--profile=<profile1,profile2,...>``
|
|
Use the given profile(s), ``--profile=help`` displays a list of the
|
|
defined profiles.
|
|
|
|
``--reset-on-next-file=<all|option1,option2,...>``
|
|
Normally, mpv will try to keep all settings when playing the next file on
|
|
the playlist, even if they were changed by the user during playback. (This
|
|
behavior is the opposite of MPlayer's, which tries to reset all settings
|
|
when starting next file.)
|
|
|
|
Default: Do not reset anything.
|
|
|
|
This can be changed with this option. It accepts a list of options, and
|
|
mpv will reset the value of these options on playback start to the initial
|
|
value. The initial value is either the default value, or as set by the
|
|
config file or command line.
|
|
|
|
In some cases, this might not work as expected. For example, ``--volume``
|
|
will only be reset if it is explicitly set in the config file or the
|
|
command line.
|
|
|
|
The special name ``all`` resets as many options as possible.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--reset-on-next-file=pause``
|
|
Reset pause mode when switching to the next file.
|
|
- ``--reset-on-next-file=fullscreen,speed``
|
|
Reset fullscreen and playback speed settings if they were changed
|
|
during playback.
|
|
- ``--reset-on-next-file=all``
|
|
Try to reset all settings that were changed during playback.
|
|
|
|
``--write-filename-in-watch-later-config``
|
|
Prepend the watch later config files with the name of the file they refer
|
|
to. This is simply written as comment on the top of the file.
|
|
|
|
.. warning::
|
|
|
|
This option may expose privacy-sensitive information and is thus
|
|
disabled by default.
|
|
|
|
``--ignore-path-in-watch-later-config``
|
|
Ignore path (i.e. use filename only) when using watch later feature.
|
|
|
|
``--show-profile=<profile>``
|
|
Show the description and content of a profile.
|
|
|
|
``--use-filedir-conf``
|
|
Look for a file-specific configuration file in the same directory as the
|
|
file that is being played. See `File-specific Configuration Files`_.
|
|
|
|
.. warning::
|
|
|
|
May be dangerous if playing from untrusted media.
|
|
|
|
``--ytdl``, ``--no-ytdl``
|
|
Enable the youtube-dl hook-script. It will look at the input URL, and will
|
|
play the video located on the website. This works with many streaming sites,
|
|
not just the one that the script is named after. This requires a recent
|
|
version of youtube-dl to be installed on the system. (Enabled by default,
|
|
except when the client API / libmpv is used.)
|
|
|
|
If the script can't do anything with an URL, it will do nothing.
|
|
|
|
(Note: this is the replacement for the now removed libquvi support.)
|
|
|
|
``--ytdl-format=<best|worst|mp4|webm|...>``
|
|
Video format/quality that is directly passed to youtube-dl. The possible
|
|
values are specific to the website and the video, for a given url the
|
|
available formats can be found with the command
|
|
``youtube-dl --list-formats URL``. See youtube-dl's documentation for
|
|
available aliases. To use experimental DASH support for youtube, use
|
|
``bestvideo+bestaudio``.
|
|
(Default: ``best``)
|
|
|
|
``--ytdl-raw-options=<key>=<value>[,<key>=<value>[,...]]``
|
|
Pass arbitrary options to youtube-dl. Parameter and argument should be
|
|
passed as a key-value pair. Options without argument must include ``=``.
|
|
|
|
There is no sanity checking so it's possible to break things (i.e.
|
|
passing invalid parameters to youtube-dl).
|
|
|
|
.. admonition:: Example
|
|
|
|
``--ytdl-raw-options=username=user,password=pass``
|
|
``--ytdl-raw-options=force-ipv6=``
|
|
|
|
Video
|
|
-----
|
|
|
|
``--vo=<driver1[:suboption1[=value]:...],driver2,...[,]>``
|
|
Specify a priority list of video output drivers to be used. For
|
|
interactive use, one would normally specify a single one to use, but in
|
|
configuration files, specifying a list of fallbacks may make sense. See
|
|
`VIDEO OUTPUT DRIVERS`_ for details and descriptions of available drivers.
|
|
|
|
``--vd=<[+|-]family1:(*|decoder1),[+|-]family2:(*|decoder2),...[-]>``
|
|
Specify a priority list of video decoders to be used, according to their
|
|
family and name. See ``--ad`` for further details. Both of these options
|
|
use the same syntax and semantics; the only difference is that they
|
|
operate on different codec lists.
|
|
|
|
.. note::
|
|
|
|
See ``--vd=help`` for a full list of available decoders.
|
|
|
|
``--vf=<filter1[=parameter1:parameter2:...],filter2,...>``
|
|
Specify a list of video filters to apply to the video stream. See
|
|
`VIDEO FILTERS`_ for details and descriptions of the available filters.
|
|
The option variants ``--vf-add``, ``--vf-pre``, ``--vf-del`` and
|
|
``--vf-clr`` exist to modify a previously specified list, but you
|
|
should not need these for typical use.
|
|
|
|
``--no-video``
|
|
Do not play video. With some demuxers this may not work. In those cases
|
|
you can try ``--vo=null`` instead.
|
|
|
|
mpv will try to download the audio only if media is streamed with
|
|
youtube-dl, because it saves bandwidth. This is done by setting the ytdl_format
|
|
to "bestaudio/best" in the ytdl_hook.lua script.
|
|
|
|
``--untimed``
|
|
Do not sleep when outputting video frames. Useful for benchmarks when used
|
|
with ``--no-audio.``
|
|
|
|
``--framedrop=<mode>``
|
|
Skip displaying some frames to maintain A/V sync on slow systems, or
|
|
playing high framerate video on video outputs that have an upper framerate
|
|
limit.
|
|
|
|
The argument selects the drop methods, and can be one of the following:
|
|
|
|
<no>
|
|
Disable any framedropping.
|
|
<vo>
|
|
Drop late frames on video output (default). This still decodes and
|
|
filters all frames, but doesn't render them on the VO. It tries to query
|
|
the display FPS (X11 only, not correct on multi-monitor systems), or
|
|
assumes infinite display FPS if that fails. Drops are indicated in
|
|
the terminal status line as ``D:`` field. If the decoder is too slow,
|
|
in theory all frames would have to be dropped (because all frames are
|
|
too late) - to avoid this, frame dropping stops if the effective
|
|
framerate is below 10 FPS.
|
|
<decoder>
|
|
Old, decoder-based framedrop mode. (This is the same as ``--framedrop=yes``
|
|
in mpv 0.5.x and before.) This tells the decoder to skip frames (unless
|
|
they are needed to decode future frames). May help with slow systems,
|
|
but can produce unwatchable choppy output, or even freeze the display
|
|
completely. Not recommended.
|
|
The ``--vd-lavc-framedrop`` option controls what frames to drop.
|
|
<decoder+vo>
|
|
Enable both modes. Not recommended.
|
|
|
|
.. note::
|
|
|
|
``--vo=vdpau`` has its own code for the ``vo`` framedrop mode. Slight
|
|
differences to other VOs are possible.
|
|
|
|
``--display-fps=<fps>``
|
|
Set the maximum assumed display FPS used with ``--framedrop``. By default
|
|
a detected value is used (X11 only, not correct on multi-monitor systems),
|
|
or infinite display FPS if that fails. Infinite FPS means only frames too
|
|
late are dropped. If a correct FPS is provided, frames that are predicted
|
|
to be too late are dropped too.
|
|
|
|
``--hwdec=<api>``
|
|
Specify the hardware video decoding API that should be used if possible.
|
|
Whether hardware decoding is actually done depends on the video codec. If
|
|
hardware decoding is not possible, mpv will fall back on software decoding.
|
|
|
|
``<api>`` can be one of the following:
|
|
|
|
:no: always use software decoding (default)
|
|
:auto: see below
|
|
:vdpau: requires ``--vo=vdpau`` or ``--vo=opengl`` (Linux only)
|
|
:vaapi: requires ``--vo=opengl`` or ``--vo=vaapi`` (Linux with Intel GPUs only)
|
|
:vaapi-copy: copies video back into system RAM (Linux with Intel GPUs only)
|
|
:vda: requires ``--vo=opengl`` (OS X only)
|
|
:dxva2-copy: copies video back to system RAM (Windows only)
|
|
:rpi: requires ``--vo=rpi`` (Raspberry Pi only - default if available)
|
|
|
|
``auto`` tries to automatically enable hardware decoding using the first
|
|
available method. This still depends what VO you are using. For example,
|
|
if you are not using ``--vo=vdpau`` or ``--vo=opengl``, vdpau decoding will
|
|
never be enabled. Also note that if the first found method doesn't actually
|
|
work, it will always fall back to software decoding, instead of trying the
|
|
next method (might matter on some Linux systems).
|
|
|
|
The ``vaapi-copy`` mode allows you to use vaapi with any VO. Because
|
|
this copies the decoded video back to system RAM, it's likely less efficient
|
|
than the ``vaapi`` mode.
|
|
|
|
.. note::
|
|
|
|
When using this switch, hardware decoding is still only done for some
|
|
codecs. See ``--hwdec-codecs`` to enable hardware decoding for more
|
|
codecs.
|
|
|
|
``--panscan=<0.0-1.0>``
|
|
Enables pan-and-scan functionality (cropping the sides of e.g. a 16:9
|
|
video to make it fit a 4:3 display without black bands). The range
|
|
controls how much of the image is cropped. May not work with all video
|
|
output drivers.
|
|
|
|
``--video-aspect=<ratio>``
|
|
Override video aspect ratio, in case aspect information is incorrect or
|
|
missing in the file being played. See also ``--no-video-aspect``.
|
|
|
|
Two values have special meaning:
|
|
|
|
:0: disable aspect ratio handling, pretend the video has square pixels
|
|
:-1: use the video stream or container aspect (default)
|
|
|
|
But note that handling of these special values might change in the future.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--video-aspect=4:3`` or ``--video-aspect=1.3333``
|
|
- ``--video-aspect=16:9`` or ``--video-aspect=1.7777``
|
|
|
|
``--no-video-aspect``
|
|
Ignore aspect ratio information from video file and assume the video has
|
|
square pixels. See also ``--video-aspect``.
|
|
|
|
``--video-unscaled``
|
|
Disable scaling of the video. If the window is larger than the video,
|
|
black bars are added. Otherwise, the video is cropped. The video still
|
|
can be influenced by the other ``--video-...`` options. (But not all; for
|
|
example ``--video-zoom`` does nothing if this option is enabled.)
|
|
|
|
The video and monitor aspects aspect will be ignored. Aspect correction
|
|
would require to scale the video in the X or Y direction, but this option
|
|
disables scaling, disabling all aspect correction.
|
|
|
|
Note that the scaler algorithm may still be used, even if the video isn't
|
|
scaled. For example, this can influence chroma conversion.
|
|
|
|
This option is disabled if the ``--no-keepaspect`` option is used.
|
|
|
|
``--video-pan-x=<value>``, ``--video-pan-y=<value>``
|
|
Moves the displayed video rectangle by the given value in the X or Y
|
|
direction. The unit is in fractions of the size of the scaled video (the
|
|
full size, even if parts of the video are not visible due to panscan or
|
|
other options).
|
|
|
|
For example, displaying a 1280x720 video fullscreen on a 1680x1050 screen
|
|
with ``--video-pan-x=-0.1`` would move the video 168 pixels to the left
|
|
(making 128 pixels of the source video invisible).
|
|
|
|
This option is disabled if the ``--no-keepaspect`` option is used.
|
|
|
|
``--video-rotate=<0-360|no>``
|
|
Rotate the video clockwise, in degrees. Currently supports 90° steps only.
|
|
If ``no`` is given, the video is never rotated, even if the file has
|
|
rotation metadata. (The rotation value is added to the rotation metadata,
|
|
which means the value ``0`` would rotate the video according to the
|
|
rotation metadata.)
|
|
|
|
``--video-stereo-mode=<mode>``
|
|
Set the stereo 3D output mode (default: ``mono``). This is done by inserting
|
|
the ``stereo3d`` conversion filter.
|
|
|
|
The mode ``mono`` is an alias to ``ml``, which refers to the left frame in
|
|
2D. This is the default, which means mpv will try to show 3D movies in 2D,
|
|
instead of the mangled 3D image not intended for consumption (such as
|
|
showing the left and right frame side by side, etc.).
|
|
|
|
The pseudo-mode ``none`` disables automatic conversion completely.
|
|
|
|
Use ``--video-stereo-mode=help`` to list all available modes. Check with
|
|
the ``stereo3d`` filter documentation to see what the names mean. Note that
|
|
some names refer to modes not supported by ``stereo3d`` - these modes can
|
|
appear in files, but can't be handled properly by mpv.
|
|
|
|
``--video-zoom=<value>``
|
|
Adjust the video display scale factor by the given value. The unit is in
|
|
fractions of the (scaled) window video size.
|
|
|
|
For example, given a 1280x720 video shown in a 1280x720 window,
|
|
``--video-zoom=-0.1`` would make the video by 128 pixels smaller in
|
|
X direction, and 72 pixels in Y direction.
|
|
|
|
This option is disabled if the ``--no-keepaspect`` option is used.
|
|
|
|
``--video-align-x=<-1-1>``, ``--video-align-y=<-1-1>``
|
|
Moves the video rectangle within the black borders, which are usually added
|
|
to pad the video to screen if video and screen aspect ratios are different.
|
|
``--video-align-y=-1`` would move the video to the top of the screen
|
|
(leaving a border only on the bottom), a value of ``0`` centers it
|
|
(default), and a value of ``1`` would put the video at the bottom of the
|
|
screen.
|
|
|
|
If video and screen aspect match perfectly, these options do nothing.
|
|
|
|
This option is disabled if the ``--no-keepaspect`` option is used.
|
|
|
|
``--correct-pts``, ``--no-correct-pts``
|
|
``--no-correct-pts`` switches mpv to a mode where video timing is
|
|
determined using a fixed framerate value (either using the ``--fps``
|
|
option, or using file information). Sometimes, files with very broken
|
|
timestamps can be played somewhat well in this mode. Note that video
|
|
filters, subtitle rendering and audio synchronization can be completely
|
|
broken in this mode.
|
|
|
|
``--fps=<float>``
|
|
Override video framerate. Useful if the original value is wrong or missing.
|
|
|
|
.. note::
|
|
|
|
Works in ``--no-correct-pts`` mode only.
|
|
|
|
``--deinterlace=<yes|no|auto>``
|
|
Enable or disable interlacing (default: auto, which usually means no).
|
|
Interlaced video shows ugly comb-like artifacts, which are visible on
|
|
fast movement. Enabling this typically inserts the yadif video filter in
|
|
order to deinterlace the video, or lets the video output apply deinterlacing
|
|
if supported.
|
|
|
|
This behaves exactly like the ``deinterlace`` input property (usually
|
|
mapped to ``Shift+D``).
|
|
|
|
``auto`` is a technicality. Strictly speaking, the default for this option
|
|
is deinterlacing disabled, but the ``auto`` case is needed if ``yadif`` was
|
|
added to the filter chain manually with ``--vf``. Then the core shouldn't
|
|
disable deinterlacing just because the ``--deinterlace`` was not set.
|
|
|
|
``--field-dominance=<auto|top|bottom>``
|
|
Set first field for interlaced content. Useful for deinterlacers that
|
|
double the framerate: ``--vf=yadif=field`` and ``--vo=vdpau:deint``.
|
|
|
|
:auto: (default) If the decoder does not export the appropriate
|
|
information, it falls back on ``top`` (top field first).
|
|
:top: top field first
|
|
:bottom: bottom field first
|
|
|
|
``--frames=<number>``
|
|
Play/convert only first ``<number>`` video frames, then quit.
|
|
|
|
``--frames=0`` loads the file, but immediately quits before initializing
|
|
playback. (Might be useful for scripts which just want to determine some
|
|
file properties.)
|
|
|
|
For audio-only playback, any value greater than 0 will quit playback
|
|
immediately after initialization. The value 0 works as with video.
|
|
|
|
``--hwdec-codecs=<codec1,codec2,...|all>``
|
|
Allow hardware decoding for a given list of codecs only. The special value
|
|
``all`` always allows all codecs.
|
|
|
|
You can get the list of allowed codecs with ``mpv --vd=help``. Remove the
|
|
prefix, e.g. instead of ``lavc:h264`` use ``h264``.
|
|
|
|
By default this is set to ``h264,vc1,wmv3,hevc``. Note that the hardware
|
|
acceleration special codecs like ``h264_vdpau`` are not relevant anymore,
|
|
and in fact have been removed from Libav in this form.
|
|
|
|
This is usually only needed with broken GPUs, where a codec is reported
|
|
as supported, but decoding causes more problems than it solves.
|
|
|
|
.. admonition:: Example
|
|
|
|
``mpv --hwdec=vdpau --vo=vdpau --hwdec-codecs=h264,mpeg2video``
|
|
Enable vdpau decoding for h264 and mpeg2 only.
|
|
|
|
``--vd-lavc-check-hw-profile=<yes|no>``
|
|
Check hardware decoder profile (default: yes). If ``no`` is set, the
|
|
highest profile of the hardware decoder is unconditionally selected, and
|
|
decoding is forced even if the profile of the video is higher than that.
|
|
The result is most likely broken decoding, but may also help if the
|
|
detected or reported profiles are somehow incorrect.
|
|
|
|
``--vd-lavc-bitexact``
|
|
Only use bit-exact algorithms in all decoding steps (for codec testing).
|
|
|
|
``--vd-lavc-fast`` (MPEG-2, MPEG-4, and H.264 only)
|
|
Enable optimizations which do not comply with the format specification and
|
|
potentially cause problems, like simpler dequantization, simpler motion
|
|
compensation, assuming use of the default quantization matrix, assuming YUV
|
|
4:2:0 and skipping a few checks to detect damaged bitstreams.
|
|
|
|
``--vd-lavc-o=<key>=<value>[,<key>=<value>[,...]]``
|
|
Pass AVOptions to libavcodec decoder. Note, a patch to make the ``o=``
|
|
unneeded and pass all unknown options through the AVOption system is
|
|
welcome. A full list of AVOptions can be found in the FFmpeg manual.
|
|
|
|
Some options which used to be direct options can be set with this
|
|
mechanism, like ``bug``, ``gray``, ``idct``, ``ec``, ``vismv``,
|
|
``skip_top`` (was ``st``), ``skip_bottom`` (was ``sb``), ``debug``.
|
|
|
|
.. admonition:: Example
|
|
|
|
``--vd--lavc-o=debug=pict``
|
|
|
|
``--vd-lavc-show-all=<yes|no>``
|
|
Show even broken/corrupt frames (default: no). If this option is set to
|
|
no, libavcodec won't output frames that were either decoded before an
|
|
initial keyframe was decoded, or frames that are recognized as corrupted.
|
|
|
|
``--vd-lavc-skiploopfilter=<skipvalue> (H.264 only)``
|
|
Skips the loop filter (AKA deblocking) during H.264 decoding. Since
|
|
the filtered frame is supposed to be used as reference for decoding
|
|
dependent frames, this has a worse effect on quality than not doing
|
|
deblocking on e.g. MPEG-2 video. But at least for high bitrate HDTV,
|
|
this provides a big speedup with little visible quality loss.
|
|
|
|
``<skipvalue>`` can be one of the following:
|
|
|
|
:none: Never skip.
|
|
:default: Skip useless processing steps (e.g. 0 size packets in AVI).
|
|
:nonref: Skip frames that are not referenced (i.e. not used for
|
|
decoding other frames, the error cannot "build up").
|
|
:bidir: Skip B-Frames.
|
|
:nonkey: Skip all frames except keyframes.
|
|
:all: Skip all frames.
|
|
|
|
``--vd-lavc-skipidct=<skipvalue> (MPEG-1/2 only)``
|
|
Skips the IDCT step. This degrades quality a lot in almost all cases
|
|
(see skiploopfilter for available skip values).
|
|
|
|
``--vd-lavc-skipframe=<skipvalue>``
|
|
Skips decoding of frames completely. Big speedup, but jerky motion and
|
|
sometimes bad artifacts (see skiploopfilter for available skip values).
|
|
|
|
``--vd-lavc-framedrop=<skipvalue>``
|
|
Set framedropping mode used with ``--framedrop`` (see skiploopfilter for
|
|
available skip values).
|
|
|
|
``--vd-lavc-threads=<0-16>``
|
|
Number of threads to use for decoding. Whether threading is actually
|
|
supported depends on codec. 0 means autodetect number of cores on the
|
|
machine and use that, up to the maximum of 16 (default: 0).
|
|
|
|
|
|
|
|
Audio
|
|
-----
|
|
|
|
``--audio-pitch-correction=<yes|no>``
|
|
If this is enabled (default), playing with a speed different from normal
|
|
automatically inserts the ``scaletempo`` audio filter. For details, see
|
|
audio filter section.
|
|
|
|
``--audio-device=<name>``
|
|
Use the given audio device. This consists of the audio output name, e.g.
|
|
``alsa``, followed by ``/``, followed by the audio output specific device
|
|
name.
|
|
|
|
You can list audio devices with ``--audio-device=help``. This outputs the
|
|
device name in quotes, followed by a description. The device name is what
|
|
you have to pass to the ``--audio-device`` option.
|
|
|
|
The default value for this option is ``auto``, which tries every audio
|
|
output in preference order with the default device.
|
|
|
|
Note that many AOs have a ``device`` sub-option, which overrides the
|
|
device selection of this option (but not the audio output selection).
|
|
Likewise, forcing an AO with ``--ao`` will override the audio output
|
|
selection of ``--audio-device`` (but not the device selection).
|
|
|
|
Currently not implemented for most AOs.
|
|
|
|
``--ao=<driver1[:suboption1[=value]:...],driver2,...[,]>``
|
|
Specify a priority list of audio output drivers to be used. For
|
|
interactive use one would normally specify a single one to use, but in
|
|
configuration files specifying a list of fallbacks may make sense. See
|
|
`AUDIO OUTPUT DRIVERS`_ for details and descriptions of available drivers.
|
|
|
|
``--af=<filter1[=parameter1:parameter2:...],filter2,...>``
|
|
Specify a list of audio filters to apply to the audio stream. See
|
|
`AUDIO FILTERS`_ for details and descriptions of the available filters.
|
|
The option variants ``--af-add``, ``--af-pre``, ``--af-del`` and
|
|
``--af-clr`` exist to modify a previously specified list, but you
|
|
should not need these for typical use.
|
|
|
|
``--audio-spdif=<codecs>``
|
|
List of codecs for which compressed audio passthrough should be used. This
|
|
works for both classic S/PDIF and HDMI.
|
|
|
|
Possible codecs are ``ac3``, ``dts``, ``dts-hd``. Multiple codecs can be
|
|
specified by separating them with ``,``. ``dts`` refers to low bitrate DTS
|
|
core, while ``dts-hd`` refers to DTS MA (receiver and OS support varies).
|
|
You should only use either ``dts`` or ``dts-hd`` (if both are specified,
|
|
and ``dts`` comes first, only ``dts`` will be used).
|
|
|
|
In general, all codecs in the ``spdif`` family listed with ``--ad=help``
|
|
are supported in theory.
|
|
|
|
.. admonition:: Warning
|
|
|
|
There is not much reason to use this. HDMI supports uncompressed
|
|
multichannel PCM, and mpv supports lossless DTS-HD decoding via
|
|
FFmpeg's libdcadec wrapper.
|
|
|
|
``--ad=<[+|-]family1:(*|decoder1),[+|-]family2:(*|decoder2),...[-]>``
|
|
Specify a priority list of audio decoders to be used, according to their
|
|
family and decoder name. Entries like ``family:*`` prioritize all decoders
|
|
of the given family. When determining which decoder to use, the first
|
|
decoder that matches the audio format is selected. If that is unavailable,
|
|
the next decoder is used. Finally, it tries all other decoders that are not
|
|
explicitly selected or rejected by the option.
|
|
|
|
``-`` at the end of the list suppresses fallback on other available
|
|
decoders not on the ``--ad`` list. ``+`` in front of an entry forces the
|
|
decoder. Both of these should not normally be used, because they break
|
|
normal decoder auto-selection!
|
|
|
|
``-`` in front of an entry disables selection of the decoder.
|
|
|
|
.. admonition:: Examples
|
|
|
|
``--ad=lavc:mp3float``
|
|
Prefer the FFmpeg/Libav ``mp3float`` decoder over all other MP3
|
|
decoders.
|
|
|
|
``--ad=spdif:ac3,lavc:*``
|
|
Always prefer spdif AC3 over FFmpeg/Libav over anything else.
|
|
|
|
``--ad=help``
|
|
List all available decoders.
|
|
|
|
.. admonition:: Warning
|
|
|
|
Enabling compressed audio passthrough (AC3 and DTS via SPDIF/HDMI) with
|
|
this option is deprecated. Use ``--audio-spdif`` instead.
|
|
|
|
``--volume=<value>``
|
|
Set the startup volume. 0 means silence, 100 means no volume reduction or
|
|
amplification. A value of -1 (the default) will not change the volume. See
|
|
also ``--softvol``.
|
|
|
|
.. note::
|
|
|
|
This was changed after the mpv 0.9 release. Before that, 100 actually
|
|
meant maximum volume. At the same time, the volume scale was made cubic,
|
|
so the old values won't match up with the new ones anyway.
|
|
|
|
``--audio-delay=<sec>``
|
|
Audio delay in seconds (positive or negative float value). Positive values
|
|
delay the audio, and negative values delay the video.
|
|
|
|
``--no-audio``
|
|
Do not play sound.
|
|
|
|
``--mute=<auto|yes|no>``
|
|
Set startup audio mute status. ``auto`` (default) will not change the mute
|
|
status. Also see ``--volume``.
|
|
|
|
``--softvol=<mode>``
|
|
Control whether to use the volume controls of the audio output driver or
|
|
the internal mpv volume filter.
|
|
|
|
:no: prefer audio driver controls, use the volume filter only if
|
|
absolutely needed
|
|
:yes: always use the volume filter
|
|
:auto: prefer the volume filter if the audio driver uses the system mixer
|
|
(default)
|
|
|
|
The intention of ``auto`` is to avoid changing system mixer settings from
|
|
within mpv with default settings. mpv is a video player, not a mixer panel.
|
|
On the other hand, mixer controls are enabled for sound servers like
|
|
PulseAudio, which provide per-application volume.
|
|
|
|
``--audio-demuxer=<[+]name>``
|
|
Use this audio demuxer type when using ``--audio-file``. Use a '+' before
|
|
the name to force it; this will skip some checks. Give the demuxer name as
|
|
printed by ``--audio-demuxer=help``.
|
|
|
|
``--ad-lavc-ac3drc=<level>``
|
|
Select the Dynamic Range Compression level for AC-3 audio streams.
|
|
``<level>`` is a float value ranging from 0 to 1, where 0 means no
|
|
compression (which is the default) and 1 means full compression (make loud
|
|
passages more silent and vice versa). Values up to 6 are also accepted, but
|
|
are purely experimental. This option only shows an effect if the AC-3 stream
|
|
contains the required range compression information.
|
|
|
|
The standard mandates that DRC is enabled by default, but mpv (and some
|
|
other players) ignore this for the sake of better audio quality.
|
|
|
|
``--ad-lavc-downmix=<yes|no>``
|
|
Whether to request audio channel downmixing from the decoder (default: yes).
|
|
Some decoders, like AC-3, AAC and DTS, can remix audio on decoding. The
|
|
requested number of output channels is set with the ``--audio-channels`` option.
|
|
Useful for playing surround audio on a stereo system.
|
|
|
|
``--ad-lavc-threads=<0-16>``
|
|
Number of threads to use for decoding. Whether threading is actually
|
|
supported depends on codec. As of this writing, it's supported for some
|
|
lossless codecs only. 0 means autodetect number of cores on the
|
|
machine and use that, up to the maximum of 16 (default: 1).
|
|
|
|
``--ad-lavc-o=<key>=<value>[,<key>=<value>[,...]]``
|
|
Pass AVOptions to libavcodec decoder. Note, a patch to make the o=
|
|
unneeded and pass all unknown options through the AVOption system is
|
|
welcome. A full list of AVOptions can be found in the FFmpeg manual.
|
|
|
|
``--ad-spdif-dtshd=<yes|no>``, ``--dtshd``, ``--no-dtshd``
|
|
If DTS is passed through, use DTS-HD.
|
|
|
|
.. admonition:: Warning
|
|
|
|
This and enabling passthrough via ``--ad`` are deprecated in favor of
|
|
using ``--audio-spdif=dts-hd``.
|
|
|
|
``--audio-channels=<number|layout>``
|
|
Request a channel layout for audio output (default: auto). This will ask
|
|
the AO to open a device with the given channel layout. It's up to the AO
|
|
to accept this layout, or to pick a fallback or to error out if the
|
|
requested layout is not supported.
|
|
|
|
The ``--audio-channels`` option either takes a channel number or an explicit
|
|
channel layout. Channel numbers refer to default layouts, e.g. 2 channels
|
|
refer to stereo, 6 refers to 5.1.
|
|
|
|
See ``--audio-channels=help`` output for defined default layouts. This also
|
|
lists speaker names, which can be used to express arbitrary channel
|
|
layouts (e.g. ``fl-fr-lfe`` is 2.1).
|
|
|
|
The default is ``--audio-channels=auto``, which tries to play audio using
|
|
the input file's channel layout. (Or more precisely, the output of the
|
|
audio filter chain.) (``empty`` is an accepted obsolete alias for ``auto``.)
|
|
|
|
This will also request the channel layout from the decoder. If the decoder
|
|
does not support the layout, it will fall back to its native channel layout.
|
|
(You can use ``--ad-lavc-downmix=no`` to make the decoder always output
|
|
its native layout.) Note that only some decoders support remixing audio.
|
|
Some that do include AC-3, AAC or DTS audio.
|
|
|
|
If the channel layout of the media file (i.e. the decoder) and the AO's
|
|
channel layout don't match, mpv will attempt to insert a conversion filter.
|
|
|
|
``--audio-display=<no|attachment>``
|
|
Setting this option to ``attachment`` (default) will display image
|
|
attachments (e.g. album cover art) when playing audio files. It will
|
|
display the first image found, and additional images are available as
|
|
video tracks.
|
|
|
|
Setting this option to ``no`` disables display of video entirely when
|
|
playing audio files.
|
|
|
|
This option has no influence on files with normal video tracks.
|
|
|
|
``--audio-file=<filename>``
|
|
Play audio from an external file while viewing a video. Each use of this
|
|
option will add a new audio track. The details are similar to how
|
|
``--sub-file`` works.
|
|
|
|
``--audio-format=<format>``
|
|
Select the sample format used for output from the audio filter layer to
|
|
the sound card. The values that ``<format>`` can adopt are listed below in
|
|
the description of the ``format`` audio filter.
|
|
|
|
``--audio-samplerate=<Hz>``
|
|
Select the output sample rate to be used (of course sound cards have
|
|
limits on this). If the sample frequency selected is different from that
|
|
of the current media, the lavrresample audio filter will be inserted into
|
|
the audio filter layer to compensate for the difference.
|
|
|
|
``--gapless-audio=<no|yes|weak>``
|
|
Try to play consecutive audio files with no silence or disruption at the
|
|
point of file change. Default: ``weak``.
|
|
|
|
:no: Disable gapless audio.
|
|
:yes: The audio device is opened using parameters chosen according to the
|
|
first file played and is then kept open for gapless playback. This
|
|
means that if the first file for example has a low sample rate, then
|
|
the following files may get resampled to the same low sample rate,
|
|
resulting in reduced sound quality. If you play files with different
|
|
parameters, consider using options such as ``--audio-samplerate``
|
|
and ``--audio-format`` to explicitly select what the shared output
|
|
format will be.
|
|
:weak: Normally, the audio device is kept open (using the format it was
|
|
first initialized with). If the audio format the decoder output
|
|
changes, the audio device is closed and reopened. This means that
|
|
you will normally get gapless audio with files that were encoded
|
|
using the same settings, but might not be gapless in other cases.
|
|
(Unlike with ``yes``, you don't have to worry about corner cases
|
|
like the first file setting a very low quality output format, and
|
|
ruining the playback of higher quality files that follow.)
|
|
|
|
.. note::
|
|
|
|
This feature is implemented in a simple manner and relies on audio
|
|
output device buffering to continue playback while moving from one file
|
|
to another. If playback of the new file starts slowly, for example
|
|
because it is played from a remote network location or because you have
|
|
specified cache settings that require time for the initial cache fill,
|
|
then the buffered audio may run out before playback of the new file
|
|
can start.
|
|
|
|
``--initial-audio-sync``, ``--no-initial-audio-sync``
|
|
When starting a video file or after events such as seeking, mpv will by
|
|
default modify the audio stream to make it start from the same timestamp
|
|
as video, by either inserting silence at the start or cutting away the
|
|
first samples. Disabling this option makes the player behave like older
|
|
mpv versions did: video and audio are both started immediately even if
|
|
their start timestamps differ, and then video timing is gradually adjusted
|
|
if necessary to reach correct synchronization later.
|
|
|
|
``--softvol-max=<100.0-1000.0>``
|
|
Set the maximum amplification level in percent (default: 130). A value of
|
|
130 will allow you to adjust the volume up to about double the normal level.
|
|
|
|
``--audio-file-auto=<no|exact|fuzzy|all>``, ``--no-audio-file-auto``
|
|
Load additional audio files matching the video filename. The parameter
|
|
specifies how external audio files are matched. ``exact`` is enabled by
|
|
default.
|
|
|
|
:no: Don't automatically load external audio files.
|
|
:exact: Load the media filename with audio file extension (default).
|
|
:fuzzy: Load all audio files containing media filename.
|
|
:all: Load all audio files in the current directory.
|
|
|
|
``--audio-client-name=<name>``
|
|
The application name the player reports to the audio API. Can be useful
|
|
if you want to force a different audio profile (e.g. with PulseAudio),
|
|
or to set your own application name when using libmpv.
|
|
|
|
``--volume-restore-data=<string>``
|
|
Used internally for use by playback resume (e.g. with ``quit_watch_later``).
|
|
Restoring value has to be done carefully, because different AOs as well as
|
|
softvol can have different value ranges, and we don't want to restore
|
|
volume if setting the volume changes it system wide. The normal options
|
|
(like ``--volume``) would always set the volume. This option was added for
|
|
restoring volume in a safer way (by storing the method used to set the
|
|
volume), and is not generally useful. Its semantics are considered private
|
|
to mpv.
|
|
|
|
Do not use.
|
|
|
|
``--audio-buffer=<seconds>``
|
|
Set the audio output minimum buffer. The audio device might actually create
|
|
a larger buffer if it pleases. If the device creates a smaller buffer,
|
|
additional audio is buffered in an additional software buffer.
|
|
|
|
Making this larger will make soft-volume and other filters react slower,
|
|
introduce additional issues on playback speed change, and block the
|
|
player on audio format changes. A smaller buffer might lead to audio
|
|
dropouts.
|
|
|
|
This option should be used for testing only. If a non-default value helps
|
|
significantly, the mpv developers should be contacted.
|
|
|
|
Default: 0.2 (200 ms).
|
|
|
|
Subtitles
|
|
---------
|
|
|
|
``--no-sub``
|
|
Do not select any subtitle when the file is loaded.
|
|
|
|
``--sub-demuxer=<[+]name>``
|
|
Force subtitle demuxer type for ``--sub-file``. Give the demuxer name as
|
|
printed by ``--sub-demuxer=help``.
|
|
|
|
``--sub-delay=<sec>``
|
|
Delays subtitles by ``<sec>`` seconds. Can be negative.
|
|
|
|
``--sub-file=subtitlefile``
|
|
Add a subtitle file to the list of external subtitles.
|
|
|
|
If you use ``--sub-file`` only once, this subtitle file is displayed by
|
|
default.
|
|
|
|
If ``--sub-file`` is used multiple times, the subtitle to use can be
|
|
switched at runtime by cycling subtitle tracks. It's possible to show
|
|
two subtitles at once: use ``--sid`` to select the first subtitle index,
|
|
and ``--secondary-sid`` to select the second index. (The index is printed
|
|
on the terminal output after the ``--sid=`` in the list of streams.)
|
|
|
|
``--secondary-sid=<ID|auto|no>``
|
|
Select a secondary subtitle stream. This is similar to ``--sid``. If a
|
|
secondary subtitle is selected, it will be rendered as toptitle (i.e. on
|
|
the top of the screen) alongside the normal subtitle, and provides a way
|
|
to render two subtitles at once.
|
|
|
|
There are some caveats associated with this feature. For example, bitmap
|
|
subtitles will always be rendered in their usual position, so selecting a
|
|
bitmap subtitle as secondary subtitle will result in overlapping subtitles.
|
|
Secondary subtitles are never shown on the terminal if video is disabled.
|
|
|
|
.. note::
|
|
|
|
Styling and interpretation of any formatting tags is disabled for the
|
|
secondary subtitle. Internally, the same mechanism as ``--no-sub-ass``
|
|
is used to strip the styling.
|
|
|
|
.. note::
|
|
|
|
If the main subtitle stream contains formatting tags which display the
|
|
subtitle at the top of the screen, it will overlap with the secondary
|
|
subtitle. To prevent this, you could use ``--no-sub-ass`` to disable
|
|
styling in the main subtitle stream.
|
|
|
|
``--sub-scale=<0-100>``
|
|
Factor for the text subtitle font size (default: 1).
|
|
|
|
.. note::
|
|
|
|
This affects ASS subtitles as well, and may lead to incorrect subtitle
|
|
rendering. Use with care, or use ``--sub-text-font-size`` instead.
|
|
|
|
``--sub-scale-by-window=<yes|no>``
|
|
Whether to scale subtitles with the window size (default: yes). If this is
|
|
disabled, changing the window size won't change the subtitle font size.
|
|
|
|
Like ``--sub-scale``, this can break ASS subtitles.
|
|
|
|
``--sub-scale-with-window=<yes|no>``
|
|
Make the subtitle font size relative to the window, instead of the video.
|
|
This is useful if you always want the same font size, even if the video
|
|
doesn't covert the window fully, e.g. because screen aspect and window
|
|
aspect mismatch (and the player adds black bars).
|
|
|
|
Default: yes.
|
|
|
|
This option is misnamed. The difference to the confusingly similar sounding
|
|
option ``--sub-scale-by-window`` is that ``--sub-scale-with-window`` still
|
|
scales with the approximate window size, while the other option disables
|
|
this scaling.
|
|
|
|
Affects plain text subtitles only (or ASS if ``--ass-style-override`` is
|
|
set high enough).
|
|
|
|
``--ass-scale-with-window=<yes|no>``
|
|
Like ``--sub-scale-with-window``, but affects subtitles in ASS format only.
|
|
Like ``--sub-scale``, this can break ASS subtitles.
|
|
|
|
Default: no.
|
|
|
|
``--embeddedfonts``, ``--no-embeddedfonts``
|
|
Use fonts embedded in Matroska container files and ASS scripts (default:
|
|
enabled). These fonts can be used for SSA/ASS subtitle rendering.
|
|
|
|
``--sub-pos=<0-100>``
|
|
Specify the position of subtitles on the screen. The value is the vertical
|
|
position of the subtitle in % of the screen height.
|
|
|
|
.. note::
|
|
|
|
This affects ASS subtitles as well, and may lead to incorrect subtitle
|
|
rendering. Use with care, or use ``--sub-text-margin-y`` instead.
|
|
|
|
``--sub-speed=<0.1-10.0>``
|
|
Multiply the subtitle event timestamps with the given value. Can be used
|
|
to fix the playback speed for frame-based subtitle formats. Works for
|
|
external text subtitles only.
|
|
|
|
.. admonition:: Example
|
|
|
|
`--sub-speed=25/23.976`` plays frame based subtitles which have been
|
|
loaded assuming a framerate of 23.976 at 25 FPS.
|
|
|
|
``--ass-force-style=<[Style.]Param=Value[,...]>``
|
|
Override some style or script info parameters.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--ass-force-style=FontName=Arial,Default.Bold=1``
|
|
- ``--ass-force-style=PlayResY=768``
|
|
|
|
.. note::
|
|
|
|
Using this option may lead to incorrect subtitle rendering.
|
|
|
|
``--ass-hinting=<none|light|normal|native>``
|
|
Set font hinting type. <type> can be:
|
|
|
|
:none: no hinting (default)
|
|
:light: FreeType autohinter, light mode
|
|
:normal: FreeType autohinter, normal mode
|
|
:native: font native hinter
|
|
|
|
.. admonition:: Warning
|
|
|
|
Enabling hinting can lead to mispositioned text (in situations it's
|
|
supposed to match up with video background), or reduce the smoothness
|
|
of animations with some badly authored ASS scripts. It is recommended
|
|
to not use this option, unless really needed.
|
|
|
|
``--ass-line-spacing=<value>``
|
|
Set line spacing value for SSA/ASS renderer.
|
|
|
|
``--ass-shaper=<simple|complex>``
|
|
Set the text layout engine used by libass.
|
|
|
|
:simple: uses Fribidi only, fast, doesn't render some languages correctly
|
|
:complex: uses HarfBuzz, slower, wider language support
|
|
|
|
``complex`` is the default. If libass hasn't been compiled against HarfBuzz,
|
|
libass silently reverts to ``simple``.
|
|
|
|
``--ass-styles=<filename>``
|
|
Load all SSA/ASS styles found in the specified file and use them for
|
|
rendering text subtitles. The syntax of the file is exactly like the ``[V4
|
|
Styles]`` / ``[V4+ Styles]`` section of SSA/ASS.
|
|
|
|
.. note::
|
|
|
|
Using this option may lead to incorrect subtitle rendering.
|
|
|
|
``--ass-style-override=<yes|no|force>``
|
|
Control whether user style overrides should be applied.
|
|
|
|
:yes: Apply all the ``--ass-*`` style override options. Changing the default
|
|
for any of these options can lead to incorrect subtitle rendering
|
|
(default).
|
|
:signfs: like ``yes``, but apply ``--sub-scale`` only to signs
|
|
:no: Render subtitles as forced by subtitle scripts.
|
|
:force: Try to force the font style as defined by the ``--sub-text-*``
|
|
options. Can break rendering easily.
|
|
|
|
``--ass-force-margins``
|
|
Enables placing toptitles and subtitles in black borders when they are
|
|
available, if the subtitles are in the ASS format.
|
|
|
|
Default: no.
|
|
|
|
``--sub-use-margins``
|
|
Enables placing toptitles and subtitles in black borders when they are
|
|
available, if the subtitles are in a plain text format (or ASS if
|
|
``--ass-style-override`` is set high enough).
|
|
|
|
Default: yes.
|
|
|
|
Renamed from ``--ass-use-margins``. To place ASS subtitles in the borders
|
|
too (like the old option did), also add ``--ass-force-margins``.
|
|
|
|
``--ass-vsfilter-aspect-compat=<yes|no>``
|
|
Stretch SSA/ASS subtitles when playing anamorphic videos for compatibility
|
|
with traditional VSFilter behavior. This switch has no effect when the
|
|
video is stored with square pixels.
|
|
|
|
The renderer historically most commonly used for the SSA/ASS subtitle
|
|
formats, VSFilter, had questionable behavior that resulted in subtitles
|
|
being stretched too if the video was stored in anamorphic format that
|
|
required scaling for display. This behavior is usually undesirable and
|
|
newer VSFilter versions may behave differently. However, many existing
|
|
scripts compensate for the stretching by modifying things in the opposite
|
|
direction. Thus, if such scripts are displayed "correctly", they will not
|
|
appear as intended. This switch enables emulation of the old VSFilter
|
|
behavior (undesirable but expected by many existing scripts).
|
|
|
|
Enabled by default.
|
|
|
|
``--ass-vsfilter-blur-compat=<yes|no>``
|
|
Scale ``\blur`` tags by video resolution instead of script resolution
|
|
(enabled by default). This is bug in VSFilter, which according to some,
|
|
can't be fixed anymore in the name of compatibility.
|
|
|
|
Note that this uses the actual video resolution for calculating the
|
|
offset scale factor, not what the video filter chain or the video output
|
|
use.
|
|
|
|
``--ass-vsfilter-color-compat=<basic|full|force-601|no>``
|
|
Mangle colors like (xy-)vsfilter do (default: basic). Historically, VSFilter
|
|
was not color space aware. This was no problem as long as the color space
|
|
used for SD video (BT.601) was used. But when everything switched to HD
|
|
(BT.709), VSFilter was still converting RGB colors to BT.601, rendered
|
|
them into the video frame, and handled the frame to the video output, which
|
|
would use BT.709 for conversion to RGB. The result were mangled subtitle
|
|
colors. Later on, bad hacks were added on top of the ASS format to control
|
|
how colors are to be mangled.
|
|
|
|
:basic: Handle only BT.601->BT.709 mangling, if the subtitles seem to
|
|
indicate that this is required (default).
|
|
:full: Handle the full ``YCbCr Matrix`` header with all video color spaces
|
|
supported by libass and mpv. This might lead to bad breakages in
|
|
corner cases and is not strictly needed for compatibility
|
|
(hopefully), which is why this is not default.
|
|
:force-601: Force BT.601->BT.709 mangling, regardless of subtitle headers
|
|
or video color space.
|
|
:no: Disable color mangling completely. All colors are RGB.
|
|
|
|
Choosing anything other than ``no`` will make the subtitle color depend on
|
|
the video color space, and it's for example in theory not possible to reuse
|
|
a subtitle script with another video file. The ``--ass-style-override``
|
|
option doesn't affect how this option is interpreted.
|
|
|
|
``--stretch-dvd-subs=<yes|no>``
|
|
Stretch DVD subtitles when playing anamorphic videos for better looking
|
|
fonts on badly mastered DVDs. This switch has no effect when the
|
|
video is stored with square pixels - which for DVD input cannot be the case
|
|
though.
|
|
|
|
Many studios tend to use bitmap fonts designed for square pixels when
|
|
authoring DVDs, causing the fonts to look stretched on playback on DVD
|
|
players. This option fixes them, however at the price of possibly
|
|
misaligning some subtitles (e.g. sign translations).
|
|
|
|
Disabled by default.
|
|
|
|
``--sub-ass``, ``--no-sub-ass``
|
|
Render ASS subtitles natively (enabled by default).
|
|
|
|
If ``--no-sub-ass`` is specified, all tags and style declarations are
|
|
stripped and ignored on display. The subtitle renderer uses the font style
|
|
as specified by the ``--sub-text-`` options instead.
|
|
|
|
.. note::
|
|
|
|
Using ``--no-sub-ass`` may lead to incorrect or completely broken
|
|
rendering of ASS/SSA subtitles. It can sometimes be useful to forcibly
|
|
override the styling of ASS subtitles, but should be avoided in general.
|
|
|
|
.. note::
|
|
|
|
Try using ``--ass-style-override=force`` instead.
|
|
|
|
``--sub-auto=<no|exact|fuzzy|all>``, ``--no-sub-auto``
|
|
Load additional subtitle files matching the video filename. The parameter
|
|
specifies how external subtitle files are matched. ``exact`` is enabled by
|
|
default.
|
|
|
|
:no: Don't automatically load external subtitle files.
|
|
:exact: Load the media filename with subtitle file extension (default).
|
|
:fuzzy: Load all subs containing media filename.
|
|
:all: Load all subs in the current and ``--sub-paths`` directories.
|
|
|
|
``--sub-codepage=<codepage>``
|
|
If your system supports ``iconv(3)``, you can use this option to specify
|
|
the subtitle codepage. By default, ENCA will be used to guess the charset.
|
|
If mpv is not compiled with ENCA, ``UTF-8:UTF-8-BROKEN`` is the default,
|
|
which means it will try to use UTF-8, otherwise the ``UTF-8-BROKEN``
|
|
pseudo codepage (see below).
|
|
|
|
The default value for this option is ``auto``, whose actual effect depends
|
|
on whether ENCA is compiled.
|
|
|
|
.. admonition:: Warning
|
|
|
|
If you force the charset, even subtitles that are known to be
|
|
UTF-8 will be recoded, which is perhaps not what you expect. Prefix
|
|
codepages with ``utf8:`` if you want the codepage to be used only if the
|
|
input is not valid UTF-8.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--sub-codepage=utf8:latin2`` Use Latin 2 if input is not UTF-8.
|
|
- ``--sub-codepage=cp1250`` Always force recoding to cp1250.
|
|
|
|
The pseudo codepage ``UTF-8-BROKEN`` is used internally. When it
|
|
is the codepage, subtitles are interpreted as UTF-8 with "Latin 1" as
|
|
fallback for bytes which are not valid UTF-8 sequences. iconv is
|
|
never involved in this mode.
|
|
|
|
If the player was compiled with ENCA support, you can control it with the
|
|
following syntax:
|
|
|
|
``--sub-codepage=enca:<language>:<fallback codepage>``
|
|
|
|
Language is specified using a two letter code to help ENCA detect
|
|
the codepage automatically. If an invalid language code is
|
|
entered, mpv will complain and list valid languages. (Note
|
|
however that this list will only be printed when the conversion code is actually
|
|
called, for example when loading an external subtitle). The
|
|
fallback codepage is used if autodetection fails. If no fallback
|
|
is specified, ``UTF-8-BROKEN`` is used.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--sub-codepage=enca:pl:cp1250`` guess the encoding, assuming the subtitles
|
|
are Polish, fall back on cp1250
|
|
- ``--sub-codepage=enca:pl`` guess the encoding for Polish, fall back on UTF-8.
|
|
- ``--sub-codepage=enca`` try universal detection, fall back on UTF-8.
|
|
|
|
If the player was compiled with libguess support, you can use it with:
|
|
|
|
``--sub-codepage=guess:<language>:<fallback codepage>``
|
|
|
|
libguess always needs a language. There is no universal detection
|
|
mode. Use ``--sub-codepage=guess:help`` to get a list of
|
|
languages subject to the same caveat as with ENCA above.
|
|
|
|
``--sub-fix-timing``, ``--no-sub-fix-timing``
|
|
By default, external text subtitles are preprocessed to remove minor gaps
|
|
or overlaps between subtitles (if the difference is smaller than 200 ms,
|
|
the gap or overlap is removed). This does not affect image subtitles,
|
|
subtitles muxed with audio/video, or subtitles in the ASS format.
|
|
|
|
``--sub-forced-only``
|
|
Display only forced subtitles for the DVD subtitle stream selected by e.g.
|
|
``--slang``.
|
|
|
|
``--sub-fps=<rate>``
|
|
Specify the framerate of the subtitle file (default: video fps).
|
|
|
|
.. note::
|
|
|
|
``<rate>`` > video fps speeds the subtitles up for frame-based
|
|
subtitle files and slows them down for time-based ones.
|
|
|
|
Also see ``--sub-speed`` option.
|
|
|
|
``--sub-gauss=<0.0-3.0>``
|
|
Apply Gaussian blur to image subtitles (default: 0). This can help making
|
|
pixelated DVD/Vobsubs look nicer. A value other than 0 also switches to
|
|
software subtitle scaling. Might be slow.
|
|
|
|
.. note::
|
|
|
|
Never applied to text subtitles.
|
|
|
|
``--sub-gray``
|
|
Convert image subtitles to grayscale. Can help making yellow DVD/Vobsubs
|
|
look nicer.
|
|
|
|
.. note::
|
|
|
|
Never applied to text subtitles.
|
|
|
|
``--sub-paths=<path1:path2:...>``
|
|
Specify extra directories to search for subtitles matching the video.
|
|
Multiple directories can be separated by ":" (";" on Windows).
|
|
Paths can be relative or absolute. Relative paths are interpreted relative
|
|
to video file directory.
|
|
|
|
.. admonition:: Example
|
|
|
|
Assuming that ``/path/to/video/video.avi`` is played and
|
|
``--sub-paths=sub:subtitles:/tmp/subs`` is specified, mpv searches for
|
|
subtitle files in these directories:
|
|
|
|
- ``/path/to/video/``
|
|
- ``/path/to/video/sub/``
|
|
- ``/path/to/video/subtitles/``
|
|
- ``/tmp/subs/``
|
|
- the ``sub`` configuration subdirectory (usually ``~/.config/mpv/sub/``)
|
|
|
|
``--sub-visibility``, ``--no-sub-visibility``
|
|
Can be used to disable display of subtitles, but still select and decode
|
|
them.
|
|
|
|
``--sub-clear-on-seek``
|
|
(Obscure, rarely useful.) Can be used to play broken mkv files with
|
|
duplicate ReadOrder fields. ReadOrder is the first field in a
|
|
Matroska-style ASS subtitle packets. It should be unique, and libass
|
|
uses it for fast elimination of duplicates. This option disables caching
|
|
of subtitles across seeks, so after a seek libass can't eliminate subtitle
|
|
packets with the same ReadOrder as earlier packets.
|
|
|
|
Window
|
|
------
|
|
|
|
``--title=<string>``
|
|
Set the window title. This is used for the video window, and if possible,
|
|
also sets the audio stream title.
|
|
|
|
Properties are expanded. (See `Property Expansion`_.)
|
|
|
|
.. warning::
|
|
|
|
There is a danger of this causing significant CPU usage, depending on
|
|
the properties used. Changing the window title is often a slow
|
|
operation, and if the title changes every frame, playback can be ruined.
|
|
|
|
``--screen=<default|0-32>``
|
|
In multi-monitor configurations (i.e. a single desktop that spans across
|
|
multiple displays), this option tells mpv which screen to display the
|
|
video on.
|
|
|
|
.. admonition:: Note (X11)
|
|
|
|
This option does not work properly with all window managers. In these
|
|
cases, you can try to use ``--geometry`` to position the window
|
|
explicitly. It's also possible that the window manager provides native
|
|
features to control which screens application windows should use.
|
|
|
|
See also ``--fs-screen``.
|
|
|
|
``--fullscreen``, ``--fs``
|
|
Fullscreen playback.
|
|
|
|
``--fs-screen=<all|current|0-32>``
|
|
In multi-monitor configurations (i.e. a single desktop that spans across
|
|
multiple displays), this option tells mpv which screen to go fullscreen to.
|
|
If ``default`` is provided mpv will fallback on using the behavior
|
|
depending on what the user provided with the ``screen`` option.
|
|
|
|
.. admonition:: Note (X11)
|
|
|
|
This option does works properly only with window managers which
|
|
understand the EWMH ``_NET_WM_FULLSCREEN_MONITORS`` hint.
|
|
|
|
.. admonition:: Note (OS X)
|
|
|
|
``all`` does not work on OS X and will behave like ``current``.
|
|
|
|
See also ``--screen``.
|
|
|
|
``--fs-black-out-screens``
|
|
|
|
OS X only. Black out other displays when going fullscreen.
|
|
|
|
``--keep-open=<yes|no|always>``
|
|
Do not terminate when playing or seeking beyond the end of the file, and
|
|
there is not next file to be played (and ``--loop`` is not used).
|
|
Instead, pause the player. When trying to seek beyond end of the file, the
|
|
player will attempt to seek to the last frame.
|
|
|
|
The following arguments can be given:
|
|
|
|
:no: If the current file ends, go to the next file or terminate.
|
|
(Default.)
|
|
:yes: Don't terminate if the current file is the last playlist entry.
|
|
Equivalent to ``--keep-open`` without arguments.
|
|
:always: Like ``yes``, but also applies to files before the last playlist
|
|
entry. This means playback will never automatically advance to
|
|
the next file.
|
|
|
|
.. note::
|
|
|
|
This option is not respected when using ``--frames``. Explicitly
|
|
skipping to the next file if the binding uses ``force`` will terminate
|
|
playback as well.
|
|
|
|
Also, if errors or unusual circumstances happen, the player can quit
|
|
anyway.
|
|
|
|
Since mpv 0.6.0, this doesn't pause if there is a next file in the playlist,
|
|
or the playlist is looped. Approximately, this will pause when the player
|
|
would normally exit, but in practice there are corner cases in which this
|
|
is not the case (e.g. ``mpv --keep-open file.mkv /dev/null`` will play
|
|
file.mkv normally, then fail to open ``/dev/null``, then exit). (In
|
|
mpv 0.8.0, ``always`` was introduced, which restores the old behavior.)
|
|
|
|
``--force-window=<yes|no|immediate>``
|
|
Create a video output window even if there is no video. This can be useful
|
|
when pretending that mpv is a GUI application. Currently, the window
|
|
always has the size 640x480, and is subject to ``--geometry``,
|
|
``--autofit``, and similar options.
|
|
|
|
.. warning::
|
|
|
|
The window is created only after initialization (to make sure default
|
|
window placement still works if the video size is different from the
|
|
``--force-window`` default window size). This can be a problem if
|
|
initialization doesn't work perfectly, such as when opening URLs with
|
|
bad network connection, or opening broken video files. The ``immediate``
|
|
mode can be used to create the window always on program start, but this
|
|
may cause other issues.
|
|
|
|
``--ontop``
|
|
Makes the player window stay on top of other windows.
|
|
|
|
``--border``, ``--no-border``
|
|
Play video with window border and decorations. Since this is on by
|
|
default, use ``--no-border`` to disable the standard window decorations.
|
|
|
|
``--on-all-workspaces``
|
|
(X11 only)
|
|
Show the video window on all virtual desktops.
|
|
|
|
``--geometry=<[W[xH]][+-x+-y]>``, ``--geometry=<x:y>``
|
|
Adjust the initial window position or size. ``W`` and ``H`` set the window
|
|
size in pixels. ``x`` and ``y`` set the window position, measured in pixels
|
|
from the top-left corner of the screen to the top-left corner of the image
|
|
being displayed. If a percentage sign (``%``) is given after the argument,
|
|
it turns the value into a percentage of the screen size in that direction.
|
|
Positions are specified similar to the standard X11 ``--geometry`` option
|
|
format, in which e.g. +10-50 means "place 10 pixels from the left border and
|
|
50 pixels from the lower border" and "--20+-10" means "place 20 pixels
|
|
beyond the right and 10 pixels beyond the top border".
|
|
|
|
If an external window is specified using the ``--wid`` option, this
|
|
option is ignored.
|
|
|
|
The coordinates are relative to the screen given with ``--screen`` for the
|
|
video output drivers that fully support ``--screen``.
|
|
|
|
.. note::
|

|
Generally only supported by GUI VOs. Ignored for encoding.
|
|
|
|
.. admonition: Note (OS X)
|
|
|
|
On Mac OS X the origin of the screen coordinate system is located on the
|
|
bottom-left corner. For instance, ``0:0`` will place the window at the
|
|
bottom-left of the screen.
|
|
|
|
.. admonition:: Note (X11)
|
|
|
|
This option does not work properly with all window managers.
|
|
|
|
.. admonition:: Examples
|
|
|
|
``50:40``
|
|
Places the window at x=50, y=40.
|
|
``50%:50%``
|
|
Places the window in the middle of the screen.
|
|
``100%:100%``
|
|
Places the window at the bottom right corner of the screen.
|
|
``50%``
|
|
Sets the window width to half the screen width. Window height is set
|
|
so that the window has the video aspect ratio.
|
|
``50%x50%``
|
|
Forces the window width and height to half the screen width and
|
|
height. Will show black borders to compensate for the video aspect
|
|
ration (with most VOs and without ``--no-keepaspect``).
|
|
``50%+10+10``
|
|
Sets the window to half the screen widths, and positions it 10
|
|
pixels below/left of the top left corner of the screen.
|
|
|
|
See also ``--autofit`` and ``--autofit-larger`` for fitting the window into
|
|
a given size without changing aspect ratio.
|
|
|
|
``--autofit=<[W[xH]]>``
|
|
Set the initial window size to a maximum size specified by ``WxH``, without
|
|
changing the window's aspect ratio. The size is measured in pixels, or if
|
|
a number is followed by a percentage sign (``%``), in percents of the
|
|
screen size.
|
|
|
|
This option never changes the aspect ratio of the window. If the aspect
|
|
ratio mismatches, the window's size is reduced until it fits into the
|
|
specified size.
|
|
|
|
Window position is not taken into account, nor is it modified by this
|
|
option (the window manager still may place the window differently depending
|
|
on size). Use ``--geometry`` to change the window position. Its effects
|
|
are applied after this option.
|
|
|
|
See ``--geometry`` for details how this is handled with multi-monitor
|
|
setups.
|
|
|
|
Use ``--autofit-larger`` instead if you just want to limit the maximum size
|
|
of the window, rather than always forcing a window size.
|
|
|
|
Use ``--geometry`` if you want to force both window width and height to a
|
|
specific size.
|
|
|
|
.. note::
|
|
|
|
Generally only supported by GUI VOs. Ignored for encoding.
|
|
|
|
.. admonition:: Examples
|
|
|
|
``70%``
|
|
Make the window width 70% of the screen size, keeping aspect ratio.
|
|
``1000``
|
|
Set the window width to 1000 pixels, keeping aspect ratio.
|
|
``70%:60%``
|
|
Make the window as large as possible, without being wider than 70%
|
|
of the screen width, or higher than 60% of the screen height.
|
|
|
|
``--autofit-larger=<[W[xH]]>``
|
|
This option behaves exactly like ``--autofit``, except the window size is
|
|
only changed if the window would be larger than the specified size.
|
|
|
|
.. admonition:: Example
|
|
|
|
``90%x80%``
|
|
If the video is larger than 90% of the screen width or 80% of the
|
|
screen height, make the window smaller until either its width is 90%
|
|
of the screen, or its height is 80% of the screen.
|
|
|
|
``--autofit-smaller=<[W[xH]]>``
|
|
This option behaves exactly like ``--autofit``, except that it sets the
|
|
minimum size of the window (just as ``--autofit-larger`` sets the maximum).
|
|
|
|
.. admonition:: Example
|
|
|
|
``500x500``
|
|
Make the window at least 500 pixels wide and 500 pixels high
|
|
(depending on the video aspect ratio, the width or height will be
|
|
larger than 500 in order to keep the aspect ratio the same).
|
|
|
|
``--window-scale=<factor>``
|
|
Resize the video window to a multiple (or fraction) of the video size. This
|
|
option is applied before ``--autofit`` and other options are applied (so
|
|
they override this option).
|
|
|
|
For example, ``--window-scale=0.5`` would show the window at half the
|
|
video size.
|
|
|
|
``--cursor-autohide=<number|no|always>``
|
|
Make mouse cursor automatically hide after given number of milliseconds.
|
|
``no`` will disable cursor autohide. ``always`` means the cursor will stay
|
|
hidden.
|
|
|
|
``--cursor-autohide-fs-only``
|
|
If this option is given, the cursor is always visible in windowed mode. In
|
|
fullscreen mode, the cursor is shown or hidden according to
|
|
``--cursor-autohide``.
|
|
|
|
``--no-fixed-vo``, ``--fixed-vo``
|
|
``--no-fixed-vo`` enforces closing and reopening the video window for
|
|
multiple files (one (un)initialization for each file).
|
|
|
|
``--force-rgba-osd-rendering``
|
|
Change how some video outputs render the OSD and text subtitles. This
|
|
does not change appearance of the subtitles and only has performance
|
|
implications. For VOs which support native ASS rendering (like ``vdpau``,
|
|
``opengl``, ``direct3d``), this can be slightly faster or slower,
|
|
depending on GPU drivers and hardware. For other VOs, this just makes
|
|
rendering slower.
|
|
|
|
``--force-window-position``
|
|
Forcefully move mpv's video output window to default location whenever
|
|
there is a change in video parameters, video stream or file. This used to
|
|
be the default behavior. Currently only affects X11 VOs.
|
|
|
|
``--heartbeat-cmd=<command>``
|
|
Command that is executed every 30 seconds during playback via *system()* -
|
|
i.e. using the shell. The time between the commands can be customized with
|
|
the ``--heartbeat-interval`` option. The command is not run while playback
|
|
is paused.
|
|
|
|
.. note::
|
|
|
|
mpv uses this command without any checking. It is your responsibility to
|
|
ensure it does not cause security problems (e.g. make sure to use full
|
|
paths if "." is in your path like on Windows). It also only works when
|
|
playing video (i.e. not with ``--no-video`` but works with
|
|
``-vo=null``).
|
|
|
|
This can be "misused" to disable screensavers that do not support the
|
|
proper X API (see also ``--stop-screensaver``). If you think this is too
|
|
complicated, ask the author of the screensaver program to support the
|
|
proper X APIs. Note that the ``--stop-screensaver`` does not influence the
|
|
heartbeat code at all.
|
|
|
|
.. admonition:: Example for xscreensaver
|
|
|
|
``mpv --heartbeat-cmd="xscreensaver-command -deactivate" file``
|
|
|
|
.. admonition:: Example for GNOME screensaver
|
|
|
|
``mpv --heartbeat-cmd="gnome-screensaver-command -p" file``
|
|
|
|
|
|
``--heartbeat-interval=<sec>``
|
|
Time between ``--heartbeat-cmd`` invocations in seconds (default: 30).
|
|
|
|
.. note::
|
|
|
|
This does not affect the normal screensaver operation in any way.
|
|
|
|
``--no-keepaspect``, ``--keepaspect``
|
|
``--no-keepaspect`` will always stretch the video to window size, and will
|
|
disable the window manager hints that force the window aspect ratio.
|
|
(Ignored in fullscreen mode.)
|
|
|
|
``--no-keepaspect-window``, ``--keepaspect-window``
|
|
``--keepaspect-window`` (the default) will lock the window size to the
|
|
video aspect. ``--no-keepaspect-window`` disables this behavior, and will
|
|
instead add black bars if window aspect and video aspect mismatch. Whether
|
|
this actually works depends on the VO backend.
|
|
(Ignored in fullscreen mode.)
|
|
|
|
``--monitoraspect=<ratio>``
|
|
Set the aspect ratio of your monitor or TV screen. A value of 0 disables a
|
|
previous setting (e.g. in the config file). Overrides the
|
|
``--monitorpixelaspect`` setting if enabled.
|
|
|
|
See also ``--monitorpixelaspect`` and ``--video-aspect``.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--monitoraspect=4:3`` or ``--monitoraspect=1.3333``
|
|
- ``--monitoraspect=16:9`` or ``--monitoraspect=1.7777``
|
|
|
|
``--monitorpixelaspect=<ratio>``
|
|
Set the aspect of a single pixel of your monitor or TV screen (default:
|
|
1). A value of 1 means square pixels (correct for (almost?) all LCDs). See
|
|
also ``--monitoraspect`` and ``--video-aspect``.
|
|
|
|
``--stop-screensaver``, ``--no-stop-screensaver``
|
|
Turns off the screensaver (or screen blanker and similar mechanisms) at
|
|
startup and turns it on again on exit (default: yes). The screensaver is
|
|
always re-enabled when the player is paused.
|
|
|
|
This is not supported on all video outputs or platforms. Sometimes it is
|
|
implemented, but does not work (happens often on GNOME). You might be able
|
|
to to work this around using ``--heartbeat-cmd`` instead.
|
|
|
|
``--wid=<ID>``
|
|
This tells mpv to attach to an existing window. If a VO is selected that
|
|
supports this option, it will use that window for video output. mpv will
|
|
scale the video to the size of this window, and will add black bars to
|
|
compensate if the aspect ratio of the video is different.
|
|
|
|
On X11, the ID is interpreted as a ``Window`` on X11. Unlike
|
|
MPlayer/mplayer2, mpv always creates its own window, and sets the wid
|
|
window as parent. The window will always be resized to cover the parent
|
|
window fully. The value ``0`` is interpreted specially, and mpv will
|
|
draw directly on the root window.
|
|
|
|
On win32, the ID is interpreted as ``HWND``. Pass it as value cast to
|
|
``intptr_t``. mpv will create its own window, and set the wid window as
|
|
parent, like with X11.
|
|
|
|
On OSX/Cocoa, the ID is interpreted as ``NSView*``. Pass it as value cast
|
|
to ``intptr_t``. mpv will creates its own sub-view. Because OSX does not
|
|
support window embedding of foreign processes, this works only with libmpv,
|
|
and will crash when used from the command line.
|
|
|
|
``--no-window-dragging``
|
|
Don't move the window when clicking on it and moving the mouse pointer.
|
|
|
|
``--x11-name``
|
|
Set the window class name for X11-based video output methods.
|
|
|
|
``--x11-netwm=<yes|no|auto>``
|
|
(X11 only)
|
|
Control the use of NetWM protocol features.
|
|
|
|
This may or may not help with broken window managers. This provides some
|
|
functionality that was implemented by the now removed ``--fstype`` option.
|
|
Actually, it is not known to the developers to which degree this option
|
|
was needed, so feedback is welcome.
|
|
|
|
Specifically, ``yes`` will force use of NetWM fullscreen support, even if
|
|
not advertised by the WM. This can be useful for WMs that are broken on
|
|
purpose, like XMonad. (XMonad supposedly doesn't advertise fullscreen
|
|
support, because Flash uses it. Apparently, applications which want to
|
|
use fullscreen anyway are supposed to either ignore the NetWM support hints,
|
|
or provide a workaround. Shame on XMonad for deliberately breaking X
|
|
protocols (as if X isn't bad enough already).
|
|
|
|
By default, NetWM support is autodetected (``auto``).
|
|
|
|
This option might be removed in the future.

Disc Devices
|
|
------------
|
|
|
|
``--cdrom-device=<path>``
|
|
Specify the CD-ROM device (default: ``/dev/cdrom``).
|
|
|
|
``--dvd-device=<path>``
|
|
Specify the DVD device or .iso filename (default: ``/dev/dvd``). You can
|
|
also specify a directory that contains files previously copied directly
|
|
from a DVD (with e.g. vobcopy).
|
|
|
|
.. admonition:: Example
|
|
|
|
``mpv dvd:// --dvd-device=/path/to/dvd/``
|
|
|
|
``--bluray-device=<path>``
|
|
(Blu-ray only)
|
|
Specify the Blu-ray disc location. Must be a directory with Blu-ray
|
|
structure.
|
|
|
|
.. admonition:: Example
|
|
|
|
``mpv bd:// --bluray-device=/path/to/bd/``
|
|
|
|
``--bluray-angle=<ID>``
|
|
Some Blu-ray discs contain scenes that can be viewed from multiple angles.
|
|
This option tells mpv which angle to use (default: 1).
|
|
|
|
``--cdda-...``
|
|
These options can be used to tune the CD Audio reading feature of mpv.
|
|
|
|
``--cdda-speed=<value>``
|
|
Set CD spin speed.
|
|
|
|
``--cdda-paranoia=<0-2>``
|
|
Set paranoia level. Values other than 0 seem to break playback of
|
|
anything but the first track.
|
|
|
|
:0: disable checking (default)
|
|
:1: overlap checking only
|
|
:2: full data correction and verification
|
|
|
|
``--cdda-sector-size=<value>``
|
|
Set atomic read size.
|
|
|
|
``--cdda-overlap=<value>``
|
|
Force minimum overlap search during verification to <value> sectors.
|
|
|
|
``--cdda-toc-bias``
|
|
Assume that the beginning offset of track 1 as reported in the TOC
|
|
will be addressed as LBA 0. Some discs need this for getting track
|
|
boundaries correctly.
|
|
|
|
``--cdda-toc-offset=<value>``
|
|
Add ``<value>`` sectors to the values reported when addressing tracks.
|
|
May be negative.
|
|
|
|
``--cdda-skip=<yes|no>``
|
|
(Never) accept imperfect data reconstruction.
|
|
|
|
``--cdda-cdtext=<yes|no>``
|
|
Print CD text. This is disabled by default, because it ruins performance
|
|
with CD-ROM drives for unknown reasons.
|
|
|
|
``--dvd-speed=<speed>``
|
|
Try to limit DVD speed (default: 0, no change). DVD base speed is 1385
|
|
kB/s, so an 8x drive can read at speeds up to 11080 kB/s. Slower speeds
|
|
make the drive more quiet. For watching DVDs, 2700 kB/s should be quiet and
|
|
fast enough. mpv resets the speed to the drive default value on close.
|
|
Values of at least 100 mean speed in kB/s. Values less than 100 mean
|
|
multiples of 1385 kB/s, i.e. ``--dvd-speed=8`` selects 11080 kB/s.
|
|
|
|
.. note::
|
|
|
|
You need write access to the DVD device to change the speed.
|
|
|
|
``--dvd-angle=<ID>``
|
|
Some DVDs contain scenes that can be viewed from multiple angles.
|
|
This option tells mpv which angle to use (default: 1).
|
|
|
|
|
|
|
|
Equalizer
|
|
---------
|
|
|
|
``--brightness=<-100-100>``
|
|
Adjust the brightness of the video signal (default: 0). Not supported by
|
|
all video output drivers.
|
|
|
|
``--contrast=<-100-100>``
|
|
Adjust the contrast of the video signal (default: 0). Not supported by all
|
|
video output drivers.
|
|
|
|
``--saturation=<-100-100>``
|
|
Adjust the saturation of the video signal (default: 0). You can get
|
|
grayscale output with this option. Not supported by all video output
|
|
drivers.
|
|
|
|
``--gamma=<-100-100>``
|
|
Adjust the gamma of the video signal (default: 0). Not supported by all
|
|
video output drivers.
|
|
|
|
``--hue=<-100-100>``
|
|
Adjust the hue of the video signal (default: 0). You can get a colored
|
|
negative of the image with this option. Not supported by all video output
|
|
drivers.
|
|
|
|
Demuxer
|
|
-------
|
|
|
|
``--demuxer=<[+]name>``
|
|
Force demuxer type. Use a '+' before the name to force it; this will skip
|
|
some checks. Give the demuxer name as printed by ``--demuxer=help``.
|
|
|
|
``--demuxer-lavf-analyzeduration=<value>``
|
|
Maximum length in seconds to analyze the stream properties.
|
|
|
|
``--demuxer-lavf-probescore=<1-100>``
|
|
Minimum required libavformat probe score. Lower values will require
|
|
less data to be loaded (makes streams start faster), but makes file
|
|
format detection less reliable. Can be used to force auto-detected
|
|
libavformat demuxers, even if libavformat considers the detection not
|
|
reliable enough. (Default: 26.)
|
|
|
|
``--demuxer-lavf-allow-mimetype=<yes|no>``
|
|
Allow deriving the format from the HTTP MIME type (default: yes). Set
|
|
this to no in case playing things from HTTP mysteriously fails, even
|
|
though the same files work from local disk.
|
|
|
|
This is default in order to reduce latency when opening HTTP streams.
|
|
|
|
``--demuxer-lavf-format=<name>``
|
|
Force a specific libavformat demuxer.
|
|
|
|
``--demuxer-lavf-hacks=<yes|no>``
|
|
By default, some formats will be handled differently from other formats
|
|
by explicitly checking for them. Most of these compensate for weird or
|
|
imperfect behavior from libavformat demuxers. Passing ``no`` disables
|
|
these. For debugging and testing only.
|
|
|
|
``--demuxer-lavf-genpts-mode=<no|lavf>``
|
|
Mode for deriving missing packet PTS values from packet DTS. ``lavf``
|
|
enables libavformat's ``genpts`` option. ``no`` disables it. This used
|
|
to be enabled by default, but then it was deemed as not needed anymore.
|
|
Enabling this might help with timestamp problems, or make them worse.
|
|
|
|
``--demuxer-lavf-o=<key>=<value>[,<key>=<value>[,...]]``
|
|
Pass AVOptions to libavformat demuxer.
|
|
|
|
Note, a patch to make the *o=* unneeded and pass all unknown options
|
|
through the AVOption system is welcome. A full list of AVOptions can
|
|
be found in the FFmpeg manual. Note that some options may conflict
|
|
with mpv options.
|
|
|
|
.. admonition:: Example
|
|
|
|
``--demuxer-lavf-o=fflags=+ignidx``
|
|
|
|
``--demuxer-lavf-probesize=<value>``
|
|
Maximum amount of data to probe during the detection phase. In the
|
|
case of MPEG-TS this value identifies the maximum number of TS packets
|
|
to scan.
|
|
|
|
``--demuxer-lavf-buffersize=<value>``
|
|
Size of the stream read buffer allocated for libavformat in bytes
|
|
(default: 32768). Lowering the size could lower latency. Note that
|
|
libavformat might reallocate the buffer internally, or not fully use all
|
|
of it.
|
|
|
|
``--demuxer-lavf-cryptokey=<hexstring>``
|
|
Encryption key the demuxer should use. This is the raw binary data of
|
|
the key converted to a hexadecimal string.
|
|
|
|
``--demuxer-mkv-subtitle-preroll``, ``--mkv-subtitle-preroll``
|
|
Try harder to show embedded soft subtitles when seeking somewhere. Normally,
|
|
it can happen that the subtitle at the seek target is not shown due to how
|
|
some container file formats are designed. The subtitles appear only if
|
|
seeking before or exactly to the position a subtitle first appears. To
|
|
make this worse, subtitles are often timed to appear a very small amount
|
|
before the associated video frame, so that seeking to the video frame
|
|
typically does not demux the subtitle at that position.
|
|
|
|
Enabling this option makes the demuxer start reading data a bit before the
|
|
seek target, so that subtitles appear correctly. Note that this makes
|
|
seeking slower, and is not guaranteed to always work. It only works if the
|
|
subtitle is close enough to the seek target.
|
|
|
|
Works with the internal Matroska demuxer only. Always enabled for absolute
|
|
and hr-seeks, and this option changes behavior with relative or imprecise
|
|
seeks only.
|
|
|
|
You can use the ``--demuxer-mkv-subtitle-preroll-secs`` option to specify
|
|
how much data the demuxer should pre-read at most in order to find subtitle
|
|
packets that may overlap. Setting this to 0 will effectively disable this
|
|
preroll mechanism. Setting a very large value can make seeking very slow,
|
|
and an extremely large value would completely reread the entire file from
|
|
start to seek target on every seek - seeking can become slower towards the
|
|
end of the file. The details are messy, and the value is actually rounded
|
|
down to the cluster with the previous video keyframe.
|
|
|
|
Some files, especially files muxed with newer mkvmerge versions, have
|
|
information embedded that can be used to determine what subtitle packets
|
|
overlap with a seek target. In these cases, mpv will reduce the amount
|
|
of data read to a minimum. (Although it will still read *all* data between
|
|
the cluster that contains the first wanted subtitle packet, and the seek
|
|
target.)
|
|
|
|
See also ``--hr-seek-demuxer-offset`` option. This option can achieve a
|
|
similar effect, but only if hr-seek is active. It works with any demuxer,
|
|
but makes seeking much slower, as it has to decode audio and video data
|
|
instead of just skipping over it.
|
|
|
|
``--mkv-subtitle-preroll`` is a deprecated alias.
|
|
|
|
``--demuxer-mkv-subtitle-preroll-secs=<value>``
|
|
See ``--demuxer-mkv-subtitle-preroll``.
|
|
|
|
``--demuxer-mkv-probe-video-duration``
|
|
When opening the file, seek to the end of it, and check what timestamp the
|
|
last video packet has, and report that as file duration. This is strictly
|
|
for compatibility with Haali only. In this mode, it's possible that opening
|
|
will be slower (especially when playing over http), or that behavior with
|
|
broken files is much worse. So don't use this option.
|
|
|
|
``--demuxer-mkv-fix-timestamps=<yes|no>``
|
|
Fix rounded Matroska timestamps (enabled by default). Matroska usually
|
|
stores timestamps rounded to milliseconds. This means timestamps jitter
|
|
by some amount around the intended timestamp. mpv can correct the timestamps
|
|
based on the framerate value stored in the file: the timestamp is rounded
|
|
to the next frame (according to the framerate), unless the new timestamp
|
|
would deviate more than 1ms from the old one. This should undo the rounding
|
|
done by the muxer.
|
|
|
|
(The allowed deviation can be less than 1ms if the file uses a non-standard
|
|
timecode scale.)
|
|
|
|
``--demuxer-rawaudio-channels=<value>``
|
|
Number of channels (or channel layout) if ``--demuxer=rawaudio`` is used
|
|
(default: stereo).
|
|
|
|
``--demuxer-rawaudio-format=<value>``
|
|
Sample format for ``--demuxer=rawaudio`` (default: s16le).
|
|
Use ``--demuxer-rawaudio-format=help`` to get a list of all formats.
|
|
|
|
``--demuxer-rawaudio-rate=<value>``
|
|
Sample rate for ``--demuxer=rawaudio`` (default: 44 kHz).
|
|
|
|
``--demuxer-rawvideo-fps=<value>``
|
|
Rate in frames per second for ``--demuxer=rawvideo`` (default: 25.0).
|
|
|
|
``--demuxer-rawvideo-w=<value>``, ``--demuxer-rawvideo-h=<value>``
|
|
Image dimension in pixels for ``--demuxer=rawvideo``.
|
|
|
|
.. admonition:: Example
|
|
|
|
Play a raw YUV sample::
|
|
|
|
mpv sample-720x576.yuv --demuxer=rawvideo \
|
|
--demuxer-rawvideo-w=720 --demuxer-rawvideo-h=576
|
|
|
|
``--demuxer-rawvideo-format=<value>``
|
|
Color space (fourcc) in hex or string for ``--demuxer=rawvideo``
|
|
(default: ``YV12``).
|
|
|
|
``--demuxer-rawvideo-mp-format=<value>``
|
|
Color space by internal video format for ``--demuxer=rawvideo``. Use
|
|
``--demuxer-rawvideo-mp-format=help`` for a list of possible formats.
|
|
|
|
``--demuxer-rawvideo-codec=<value>``
|
|
Set the video codec instead of selecting the rawvideo codec when using
|
|
``--demuxer=rawvideo``. This uses the same values as codec names in
|
|
``--vd`` (but it does not accept decoder names).
|
|
|
|
``--demuxer-rawvideo-size=<value>``
|
|
Frame size in bytes when using ``--demuxer=rawvideo``.
|
|
|
|
``--demuxer-thread=<yes|no>``
|
|
Run the demuxer in a separate thread, and let it prefetch a certain amount
|
|
of packets (default: yes). Having this enabled may lead to smoother
|
|
playback, but on the other hand can add delays to seeking or track
|
|
switching.
|
|
|
|
``--demuxer-readahead-secs=<seconds>``
|
|
If ``--demuxer-thread`` is enabled, this controls how much the demuxer
|
|
should buffer ahead in seconds (default: 1). As long as no packet has
|
|
a timestamp difference higher than the readahead amount relative to the
|
|
last packet returned to the decoder, the demuxer keeps reading.
|
|
|
|
Note that the ``--cache-secs`` option will override this value if a cache
|
|
is enabled, and the value is larger.
|
|
|
|
(This value tends to be fuzzy, because many file formats don't store linear
|
|
timestamps.)
|
|
|
|
``--demuxer-readahead-packets=<packets>``
|
|
If ``--demuxer-thread`` is enabled, this controls how much the demuxer
|
|
should buffer ahead. As long as the number of packets in the packet queue
|
|
doesn't exceed ``--demuxer-readahead-packets``, and the total number of
|
|
bytes doesn't exceed ``--demuxer-readahead-bytes``, the thread keeps
|
|
reading ahead.
|
|
|
|
Note that if you set these options near the maximum, you might get a
|
|
packet queue overflow warning.
|
|
|
|
See ``--list-options`` for defaults and value range.
|
|
|
|
``--demuxer-readahead-bytes=<bytes>``
|
|
See ``--demuxer-readahead-packets``.
|
|
|
|
|
|
Input
|
|
-----
|
|
|
|
``--native-keyrepeat``
|
|
Use system settings for keyrepeat delay and rate, instead of
|
|
``--input-ar-delay`` and ``--input-ar-rate``. (Whether this applies
|
|
depends on the VO backend and how it handles keyboard input. Does not
|
|
apply to terminal input.)
|
|
|
|
``--input-ar-delay``
|
|
Delay in milliseconds before we start to autorepeat a key (0 to disable).
|
|
|
|
``--input-ar-rate``
|
|
Number of key presses to generate per second on autorepeat.
|
|
|
|
``--input-conf=<filename>``
|
|
Specify input configuration file other than the default location in the mpv
|
|
configuration directory (usually ``~/.config/mpv/input.conf``).
|
|
|
|
``--no-input-default-bindings``
|
|
Disable mpv default (built-in) key bindings.
|
|
|
|
``--input-cmdlist``
|
|
Prints all commands that can be bound to keys.
|
|
|
|
``--input-doubleclick-time=<milliseconds>``
|
|
Time in milliseconds to recognize two consecutive button presses as a
|
|
double-click (default: 300).
|
|
|
|
``--input-keylist``
|
|
Prints all keys that can be bound to commands.
|
|
|
|
``--input-key-fifo-size=<2-65000>``
|
|
Specify the size of the FIFO that buffers key events (default: 7). If it
|
|
is too small some events may be lost. The main disadvantage of setting it
|
|
to a very large value is that if you hold down a key triggering some
|
|
particularly slow command then the player may be unresponsive while it
|
|
processes all the queued commands.
|
|
|
|
``--input-test``
|
|
Input test mode. Instead of executing commands on key presses, mpv
|
|
will show the keys and the bound commands on the OSD. Has to be used
|
|
with a dummy video, and the normal ways to quit the player will not
|
|
work (key bindings that normally quit will be shown on OSD only, just
|
|
like any other binding). See `INPUT.CONF`_.
|
|
|
|
``--input-file=<filename>``
|
|
Read commands from the given file. Mostly useful with a FIFO. Since
|
|
mpv 0.7.0 also understands JSON commands (see `JSON IPC`_), but you can't
|
|
get replies or events. Use ``--input-unix-socket`` for something
|
|
bi-directional. On MS Windows, JSON commands are not available.
|
|
|
|
This can also specify a direct file descriptor with ``fd://N`` (UNIX only).
|
|
In this case, JSON replies will be written if the FD is writable.
|
|
|
|
.. note::
|
|
|
|
When the given file is a FIFO mpv opens both ends, so you can do several
|
|
`echo "seek 10" > mp_pipe` and the pipe will stay valid.
|
|
|
|
``--input-terminal``, ``--no-input-terminal``
|
|
``--no-input-terminal`` prevents the player from reading key events from
|
|
standard input. Useful when reading data from standard input. This is
|
|
automatically enabled when ``-`` is found on the command line. There are
|
|
situations where you have to set it manually, e.g. if you open
|
|
``/dev/stdin`` (or the equivalent on your system), use stdin in a playlist
|
|
or intend to read from stdin later on via the loadfile or loadlist slave
|
|
commands.
|
|
|
|
``--input-unix-socket=<filename>``
|
|
Enable the IPC support and create the listening socket at the given path.
|
|
|
|
See `JSON IPC`_ for details.
|
|
|
|
Not available on MS Windows.
|
|
|
|
``--input-appleremote=<yes|no>``
|
|
(OS X only)
|
|
Enable/disable Apple Remote support. Enabled by default (except for libmpv).
|
|
|
|
``--input-cursor``, ``--no-input-cursor``
|
|
Permit mpv to receive pointer events reported by the video output
|
|
driver. Necessary to use the OSC, or to select the buttons in DVD menus.
|
|
Support depends on the VO in use.
|
|
|
|
``--input-media-keys=<yes|no>``
|
|
(OS X only)
|
|
Enable/disable media keys support. Enabled by default (except for libmpv).
|
|
|
|
``--input-right-alt-gr``, ``--no-input-right-alt-gr``
|
|
(Cocoa and Windows only)
|
|
Use the right Alt key as Alt Gr to produce special characters. If disabled,
|
|
count the right Alt as an Alt modifier key. Enabled by default.
|
|
|
|
``--input-vo-keyboard=<yes|no>``
|
|
Disable all keyboard input on for VOs which can't participate in proper
|
|
keyboard input dispatching. May not affect all VOs. Generally useful for
|
|
embedding only.
|
|
|
|
On X11, a sub-window with input enabled grabs all keyboard input as long
|
|
as it is 1. a child of a focused window, and 2. the mouse is inside of
|
|
the sub-window. The can steal away all keyboard input from the
|
|
application embedding the mpv window, and on the other hand, the mpv
|
|
window will receive no input if the mouse is outside of the mpv window,
|
|
even though mpv has focus. Modern toolkits work around this weird X11
|
|
behavior, but naively embedding foreign windows breaks it.
|
|
|
|
The only way to handle this reasonably is using the XEmbed protocol, which
|
|
was designed to solve these problems. GTK provides ``GtkSocket``, which
|
|
supports XEmbed. Qt doesn't seem to provide anything working in newer
|
|
versions.
|
|
|
|
If the embedder supports XEmbed, input should work with default settings
|
|
and with this option disabled. Note that ``input-default-bindings`` is
|
|
disabled by default in libmpv as well - it should be enabled if you want
|
|
the mpv default key bindings.
|
|
|
|
(This option was renamed from ``--input-x11-keyboard``.)
|
|
|
|
``--input-app-events=<yes|no>``
|
|
(OS X only)
|
|
Enable/disable application wide keyboard events so that keyboard shortcuts
|
|
can be processed without a window. Enabled by default (except for libmpv).
|
|
|
|
OSD
|
|
---
|
|
|
|
``--osc``, ``--no-osc``
|
|
Whether to load the on-screen-controller (default: yes).
|
|
|
|
``--no-osd-bar``, ``--osd-bar``
|
|
Disable display of the OSD bar. This will make some things (like seeking)
|
|
use OSD text messages instead of the bar.
|
|
|
|
You can configure this on a per-command basis in input.conf using ``osd-``
|
|
prefixes, see ``Input command prefixes``. If you want to disable the OSD
|
|
completely, use ``--osd-level=0``.
|
|
|
|
``--osd-duration=<time>``
|
|
Set the duration of the OSD messages in ms (default: 1000).
|
|
|
|
``--osd-font=<pattern>``, ``--sub-text-font=<pattern>``
|
|
Specify font to use for OSD and for subtitles that do not themselves
|
|
specify a particular font. The default is ``sans-serif``.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--osd-font='Bitstream Vera Sans'``
|
|
- ``--osd-font='Bitstream Vera Sans:style=Bold'`` (fontconfig pattern)
|
|
|
|
.. note::
|
|
|
|
The ``--sub-text-font`` option (and most other ``--sub-text-``
|
|
options) are ignored when ASS-subtitles are rendered, unless the
|
|
``--no-sub-ass`` option is specified.
|
|
|
|
``--osd-font-size=<size>``, ``--sub-text-font-size=<size>``
|
|
Specify the OSD/sub font size. The unit is the size in scaled pixels at a
|
|
window height of 720. The actual pixel size is scaled with the window
|
|
height: if the window height is larger or smaller than 720, the actual size
|
|
of the text increases or decreases as well.
|
|
|
|
Default: 55.
|
|
|
|
``--osd-msg1=<string>``
|
|
Show this string as message on OSD with OSD level 1 (visible by default).
|
|
The message will be visible by default, and as long no other message
|
|
covers it, and the OSD level isn't changed (see ``--osd-level``).
|
|
Expands properties; see `Property Expansion`_.
|
|
|
|
``--osd-msg2=<string>``
|
|
Similar as ``--osd-msg1``, but for OSD level 2. If this is an empty string
|
|
(default), then the playback time is shown.
|
|
|
|
``--osd-msg3=<string>``
|
|
Similar as ``--osd-msg1``, but for OSD level 3. If this is an empty string
|
|
(default), then the playback time, duration, and some more information is
|
|
shown.
|
|
|
|
This is also used for the ``show_progress`` command (by default mapped to
|
|
``P``), or in some non-default cases when seeking.
|
|
|
|
``--osd-status-msg`` is a legacy equivalent (but with a minor difference).
|
|
|
|
``--osd-status-msg=<string>``
|
|
Show a custom string during playback instead of the standard status text.
|
|
This overrides the status text used for ``--osd-level=3``, when using the
|
|
``show_progress`` command (by default mapped to ``P``), or in some
|
|
non-default cases when seeking. Expands properties. See
|
|
`Property Expansion`_.
|
|
|
|
This option has been replaced with ``--osd-msg3``. The only difference is
|
|
that this option implicitly includes ``${osd-sym-cc}``. This option is
|
|
ignored if ``--osd-msg3`` is not empty.
|
|
|
|
``--osd-playing-msg=<string>``
|
|
Show a message on OSD when playback starts. The string is expanded for
|
|
properties, e.g. ``--osd-playing-msg='file: ${filename}'`` will show the
|
|
message ``file:`` followed by a space and the currently played filename.
|
|
|
|
See `Property Expansion`_.
|
|
|
|
``--osd-bar-align-x=<-1-1>``
|
|
Position of the OSD bar. -1 is far left, 0 is centered, 1 is far right.
|
|
Fractional values (like 0.5) are allowed.
|
|
|
|
``--osd-bar-align-y=<-1-1>``
|
|
Position of the OSD bar. -1 is top, 0 is centered, 1 is bottom.
|
|
Fractional values (like 0.5) are allowed.
|
|
|
|
``--osd-bar-w=<1-100>``
|
|
Width of the OSD bar, in percentage of the screen width (default: 75).
|
|
A value of 50 means the bar is half the screen wide.
|
|
|
|
``--osd-bar-h=<0.1-50>``
|
|
Height of the OSD bar, in percentage of the screen height (default: 3.125).
|
|
|
|
``--osd-back-color=<color>``, ``--sub-text-back-color=<color>``
|
|
See ``--osd-color``. Color used for OSD/sub text background.
|
|
|
|
``--osd-blur=<0..20.0>``, ``--sub-text-blur=<0..20.0>``
|
|
Gaussian blur factor. 0 means no blur applied (default).
|
|
|
|
``--osd-bold=<yes|no>``, ``--sub-text-bold=<yes|no>``
|
|
Format text on bold.
|
|
|
|
``--osd-border-color=<color>``, ``--sub-text-border-color=<color>``
|
|
See ``--osd-color``. Color used for the OSD/sub font border.
|
|
|
|
.. note::
|
|
|
|
ignored when ``--osd-back-color``/``--sub-text-back-color`` is
|
|
specified (or more exactly: when that option is not set to completely
|
|
transparent).
|
|
|
|
``--osd-border-size=<size>``, ``--sub-text-border-size=<size>``
|
|
Size of the OSD/sub font border in scaled pixels (see ``--osd-font-size``
|
|
for details). A value of 0 disables borders.
|
|
|
|
Default: 3.
|
|
|
|
``--osd-color=<color>``, ``--sub-text-color=<color>``
|
|
Specify the color used for OSD/unstyled text subtitles.
|
|
|
|
The color is specified in the form ``r/g/b``, where each color component
|
|
is specified as number in the range 0.0 to 1.0. It's also possible to
|
|
specify the transparency by using ``r/g/b/a``, where the alpha value 0
|
|
means fully transparent, and 1.0 means opaque. If the alpha component is
|
|
not given, the color is 100% opaque.
|
|
|
|
Passing a single number to the option sets the OSD to gray, and the form
|
|
``gray/a`` lets you specify alpha additionally.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--osd-color=1.0/0.0/0.0`` set OSD to opaque red
|
|
- ``--osd-color=1.0/0.0/0.0/0.75`` set OSD to opaque red with 75% alpha
|
|
- ``--osd-color=0.5/0.75`` set OSD to 50% gray with 75% alpha
|
|
|
|
Alternatively, the color can be specified as a RGB hex triplet in the form
|
|
``#RRGGBB``, where each 2-digit group expresses a color value in the
|
|
range 0 (``00``) to 255 (``FF``). For example, ``#FF0000`` is red.
|
|
This is similar to web colors. Alpha is given with ``#AARRGGBB``.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--osd-color='#FF0000'`` set OSD to opaque red
|
|
- ``--osd-color='#C0808080'`` set OSD to 50% gray with 75% alpha
|
|
|
|
``--osd-fractions``
|
|
Show OSD times with fractions of seconds (in millisecond precision). Useful
|
|
to see the exact timestamp of a video frame.
|
|
|
|
``--osd-level=<0-3>``
|
|
Specifies which mode the OSD should start in.
|
|
|
|
:0: OSD completely disabled (subtitles only)
|
|
:1: enabled (shows up only on user interaction)
|
|
:2: enabled + current time visible by default
|
|
:3: enabled + ``--osd-status-msg`` (current time and status by default)
|
|
|
|
``--osd-margin-x=<size>, --sub-text-margin-x=<size>``
|
|
Left and right screen margin for the OSD/subs in scaled pixels (see
|
|
``--osd-font-size`` for details).
|
|
|
|
This option specifies the distance of the OSD to the left, as well as at
|
|
which distance from the right border long OSD text will be broken.
|
|
|
|
Default: 25.
|
|
|
|
``--osd-margin-y=<size>, --sub-text-margin-y=<size>``
|
|
Top and bottom screen margin for the OSD/subs in scaled pixels (see
|
|
``--osd-font-size`` for details).
|
|
|
|
This option specifies the vertical margins of the OSD. This is also used
|
|
for unstyled text subtitles. If you just want to raise the vertical
|
|
subtitle position, use ``--sub-pos``.
|
|
|
|
Default: 22.
|
|
|
|
``--osd-align-x=<left|center|right>``, ``--sub-text-align-x=...``
|
|
Control to which corner of the screen OSD or text subtitles should be
|
|
aligned to (default: ``center`` for subs, ``left`` for OSD).
|
|
|
|
Never applied to ASS subtitles, except in ``--no-sub-ass`` mode. Likewise,
|
|
this does not apply to image subtitles.
|
|
|
|
``--osd-align-y=<top|center|bottom>`` ``--sub-text-align-y=...``
|
|
Vertical position (default: ``bottom`` for subs, ``top`` for OSD).
|
|
Details see ``--osd-align-x``.
|
|
|
|
``--osd-scale=<factor>``
|
|
OSD font size multiplier, multiplied with ``--osd-font-size`` value.
|
|
|
|
``--osd-scale-by-window=<yes|no>``
|
|
Whether to scale the OSD with the window size (default: yes). If this is
|
|
disabled, ``--osd-font-size`` and other OSD options that use scaled pixels
|
|
are always in actual pixels. The effect is that changing the window size
|
|
won't change the OSD font size.
|
|
|
|
``--osd-shadow-color=<color>, --sub-text-shadow-color=<color>``
|
|
See ``--osd-color``. Color used for OSD/sub text shadow.
|
|
|
|
``--osd-shadow-offset=<size>, --sub-text-shadow-offset=<size>``
|
|
Displacement of the OSD/sub text shadow in scaled pixels (see
|
|
``--osd-font-size`` for details). A value of 0 disables shadows.
|
|
|
|
Default: 0.
|
|
|
|
``--osd-spacing=<size>, --sub-text-spacing=<size>``
|
|
Horizontal OSD/sub font spacing in scaled pixels (see ``--osd-font-size``
|
|
for details). This value is added to the normal letter spacing. Negative
|
|
values are allowed.
|
|
|
|
Default: 0.
|
|
|
|
``--use-text-osd=<yes|no>``
|
|
Disable text OSD rendering completely. (This includes the complete OSC as
|
|
well.) This is mostly useful for avoiding loading fontconfig in situations
|
|
where fontconfig does not behave well, and OSD is unused - this could for
|
|
example allow GUI programs using libmpv to workaround fontconfig issues.
|
|
|
|
Note that selecting subtitles of any kind still initializes fontconfig.
|
|
|
|
Default: ``no``.
|
|
|
|
|
|
Screenshot
|
|
----------
|
|
|
|
``--screenshot-format=<type>``
|
|
Set the image file type used for saving screenshots.
|
|
|
|
Available choices:
|
|
|
|
:png: PNG
|
|
:ppm: PPM
|
|
:pgm: PGM
|
|
:pgmyuv: PGM with YV12 pixel format
|
|
:tga: TARGA
|
|
:jpg: JPEG (default)
|
|
:jpeg: JPEG (same as jpg, but with .jpeg file ending)
|
|
|
|
``--screenshot-tag-colorspace=<yes|no>``
|
|
Tag screenshots with the appropriate colorspace.
|
|
|
|
Note that not all formats are supported.
|
|
|
|
Default: ``yes``.
|
|
|
|
``--screenshot-high-bit-depth=<yes|no>``
|
|
If possible, write screenshots with a bit depth similar to the source
|
|
video (default: yes). This is interesting in particular for PNG, as this
|
|
sometimes triggers writing 16 bit PNGs with huge file sizes.
|
|
|
|
``--screenshot-template=<template>``
|
|
Specify the filename template used to save screenshots. The template
|
|
specifies the filename without file extension, and can contain format
|
|
specifiers, which will be substituted when taking a screenshot.
|
|
By default the template is ``mpv-shot%n``, which results in filenames like
|
|
``mpv-shot0012.png`` for example.
|
|
|
|
The template can start with a relative or absolute path, in order to
|
|
specify a directory location where screenshots should be saved.
|
|
|
|
If the final screenshot filename points to an already existing file, the
|
|
file will not be overwritten. The screenshot will either not be saved, or if
|
|
the template contains ``%n``, saved using different, newly generated
|
|
filename.
|
|
|
|
Allowed format specifiers:
|
|
|
|
``%[#][0X]n``
|
|
A sequence number, padded with zeros to length X (default: 04). E.g.
|
|
passing the format ``%04n`` will yield ``0012`` on the 12th screenshot.
|
|
The number is incremented every time a screenshot is taken or if the
|
|
file already exists. The length ``X`` must be in the range 0-9. With
|
|
the optional # sign, mpv will use the lowest available number. For
|
|
example, if you take three screenshots--0001, 0002, 0003--and delete
|
|
the first two, the next two screenshots will not be 0004 and 0005, but
|
|
0001 and 0002 again.
|
|
``%f``
|
|
Filename of the currently played video.
|
|
``%F``
|
|
Same as ``%f``, but strip the file extension, including the dot.
|
|
``%x``
|
|
Directory path of the currently played video. If the video is not on
|
|
the filesystem (but e.g. ``http://``), this expand to an empty string.
|
|
``%X{fallback}``
|
|
Same as ``%x``, but if the video file is not on the filesystem, return
|
|
the fallback string inside the ``{...}``.
|
|
``%p``
|
|
Current playback time, in the same format as used in the OSD. The
|
|
result is a string of the form "HH:MM:SS". For example, if the video is
|
|
at the time position 5 minutes and 34 seconds, ``%p`` will be replaced
|
|
with "00:05:34".
|
|
``%P``
|
|
Similar to ``%p``, but extended with the playback time in milliseconds.
|
|
It is formatted as "HH:MM:SS.mmm", with "mmm" being the millisecond
|
|
part of the playback time.
|
|
|
|
.. note::
|
|
|
|
This is a simple way for getting unique per-frame timestamps. Frame
|
|
numbers would be more intuitive, but are not easily implementable
|
|
because container formats usually use time stamps for identifying
|
|
frames.)
|
|
``%wX``
|
|
Specify the current playback time using the format string ``X``.
|
|
``%p`` is like ``%wH:%wM:%wS``, and ``%P`` is like ``%wH:%wM:%wS.%wT``.
|
|
|
|
Valid format specifiers:
|
|
``%wH``
|
|
hour (padded with 0 to two digits)
|
|
``%wh``
|
|
hour (not padded)
|
|
``%wM``
|
|
minutes (00-59)
|
|
``%wm``
|
|
total minutes (includes hours, unlike ``%wM``)
|
|
``%wS``
|
|
seconds (00-59)
|
|
``%ws``
|
|
total seconds (includes hours and minutes)
|
|
``%wf``
|
|
like ``%ws``, but as float
|
|
``%wT``
|
|
milliseconds (000-999)
|
|
|
|
``%tX``
|
|
Specify the current local date/time using the format ``X``. This format
|
|
specifier uses the UNIX ``strftime()`` function internally, and inserts
|
|
the result of passing "%X" to ``strftime``. For example, ``%tm`` will
|
|
insert the number of the current month as number. You have to use
|
|
multiple ``%tX`` specifiers to build a full date/time string.
|
|
``%{prop[:fallback text]}``
|
|
Insert the value of the slave property 'prop'. E.g. ``%{filename}`` is
|
|
the same as ``%f``. If the property does not exist or is not available,
|
|
an error text is inserted, unless a fallback is specified.
|
|
``%%``
|
|
Replaced with the ``%`` character itself.
|
|
|
|
``--screenshot-directory=<path>``
|
|
Store screenshots in this directory. This path is joined with the filename
|
|
generated by ``--screenshot-template``. If the template filename is already
|
|
absolute, the directory is ignored.
|
|
|
|
If the directory does not exist, it is created on the first screenshot. If
|
|
it is not a directory, an error is generated when trying to write a
|
|
screenshot.
|
|
|
|
This option is not set by default, and thus will write screenshots to the
|
|
directory from which mpv was started. In pseudo-gui mode
|
|
(see `PSEUDO GUI MODE`_), this is set to the desktop.
|
|
|
|
``--screenshot-jpeg-quality=<0-100>``
|
|
Set the JPEG quality level. Higher means better quality. The default is 90.
|
|
|
|
``--screenshot-jpeg-source-chroma=<yes|no>``
|
|
Write JPEG files with the same chroma subsampling as the video
|
|
(default: yes). If disabled, the libjpeg default is used.
|
|
|
|
``--screenshot-png-compression=<0-9>``
|
|
Set the PNG compression level. Higher means better compression. This will
|
|
affect the file size of the written screenshot file and the time it takes
|
|
to write a screenshot. Too high compression might occupy enough CPU time to
|
|
interrupt playback. The default is 7.
|
|
|
|
``--screenshot-png-filter=<0-5>``
|
|
Set the filter applied prior to PNG compression. 0 is none, 1 is "sub", 2 is
|
|
"up", 3 is "average", 4 is "Paeth", and 5 is "mixed". This affects the level
|
|
of compression that can be achieved. For most images, "mixed" achieves the
|
|
best compression ratio, hence it is the default.
|
|
|
|
|
|
Software Scaler
|
|
---------------
|
|
|
|
``--sws-scaler=<name>``
|
|
Specify the software scaler algorithm to be used with ``--vf=scale``. This
|
|
also affects video output drivers which lack hardware acceleration,
|
|
e.g. ``x11``. See also ``--vf=scale``.
|
|
|
|
To get a list of available scalers, run ``--sws-scaler=help``.
|
|
|
|
Default: ``bicubic``.
|
|
|
|
``--sws-lgb=<0-100>``
|
|
Software scaler Gaussian blur filter (luma). See ``--sws-scaler``.
|
|
|
|
``--sws-cgb=<0-100>``
|
|
Software scaler Gaussian blur filter (chroma). See ``--sws-scaler``.
|
|
|
|
``--sws-ls=<-100-100>``
|
|
Software scaler sharpen filter (luma). See ``--sws-scaler``.
|
|
|
|
``--sws-cs=<-100-100>``
|
|
Software scaler sharpen filter (chroma). See ``--sws-scaler``.
|
|
|
|
``--sws-chs=<h>``
|
|
Software scaler chroma horizontal shifting. See ``--sws-scaler``.
|
|
|
|
``--sws-cvs=<v>``
|
|
Software scaler chroma vertical shifting. See ``--sws-scaler``.
|
|
|
|
|
|
Terminal
|
|
--------
|
|
|
|
``--quiet``
|
|
Make console output less verbose; in particular, prevents the status line
|
|
(i.e. AV: 3.4 (00:00:03.37) / 5320.6 ...) from being displayed.
|
|
Particularly useful on slow terminals or broken ones which do not properly
|
|
handle carriage return (i.e. ``\r``).
|
|
|
|
Also see ``--really-quiet`` and ``--msg-level``.
|
|
|
|
``--really-quiet``
|
|
Display even less output and status messages than with ``--quiet``.
|
|
|
|
``--no-terminal``, ``--terminal``
|
|
Disable any use of the terminal and stdin/stdout/stderr. This completely
|
|
silences any message output.
|
|
|
|
Unlike ``--really-quiet``, this disables input and terminal initialization
|
|
as well.
|
|
|
|
``--no-msg-color``
|
|
Disable colorful console output on terminals.
|
|
|
|
``--msg-level=<module1=level1,module2=level2,...>``
|
|
Control verbosity directly for each module. The ``all`` module changes the
|
|
verbosity of all the modules not explicitly specified on the command line.
|
|
|
|
Run mpv with ``--msg-level=all=trace`` to see all messages mpv outputs. You
|
|
can use the module names printed in the output (prefixed to each line in
|
|
``[...]``) to limit the output to interesting modules.
|
|
|
|
.. note::
|
|
|
|
Some messages are printed before the command line is parsed and are
|
|
therefore not affected by ``--msg-level``. To control these messages,
|
|
you have to use the ``MPV_VERBOSE`` environment variable; see
|
|
`ENVIRONMENT VARIABLES`_ for details.
|
|
|
|
Available levels:
|
|
|
|
:no: complete silence
|
|
:fatal: fatal messages only
|
|
:error: error messages
|
|
:warn: warning messages
|
|
:info: informational messages
|
|
:status: status messages (default)
|
|
:v: verbose messages
|
|
:debug: debug messages
|
|
:trace: very noisy debug messages
|
|
|
|
``--term-osd, --no-term-osd``, ``--term-osd=force``
|
|
Display OSD messages on the console when no video output is available.
|
|
Enabled by default.
|
|
|
|
``force`` enables terminal OSD even if a video window is created.
|
|
|
|
``--term-osd-bar``, ``--no-term-osd-bar``
|
|
Enable printing a progress bar under the status line on the terminal.
|
|
(Disabled by default.)
|
|
|
|
``--term-osd-bar-chars=<string>``
|
|
Customize the ``--term-osd-bar`` feature. The string is expected to
|
|
consist of 5 characters (start, left space, position indicator,
|
|
right space, end). You can use Unicode characters, but note that double-
|
|
width characters will not be treated correctly.
|
|
|
|
Default: ``[-+-]``.
|
|
|
|
``--term-playing-msg=<string>``
|
|
Print out a string after starting playback. The string is expanded for
|
|
properties, e.g. ``--term-playing-msg='file: ${filename}'`` will print the string
|
|
``file:`` followed by a space and the currently played filename.
|
|
|
|
See `Property Expansion`_.
|
|
|
|
``--term-status-msg=<string>``
|
|
Print out a custom string during playback instead of the standard status
|
|
line. Expands properties. See `Property Expansion`_.
|
|
|
|
``--msg-module``
|
|
Prepend module name to each console message.
|
|
|
|
``--msg-time``
|
|
Prepend timing information to each console message.
|
|
|
|
|
|
TV
|
|
--
|
|
|
|
``--tv-...``
|
|
These options tune various properties of the TV capture module. For
|
|
watching TV with mpv, use ``tv://`` or ``tv://<channel_number>`` or
|
|
even ``tv://<channel_name>`` (see option ``tv-channels`` for ``channel_name``
|
|
below) as a media URL. You can also use ``tv:///<input_id>`` to start
|
|
watching a video from a composite or S-Video input (see option ``input`` for
|
|
details).
|
|
|
|
``--tv-device=<value>``
|
|
Specify TV device (default: ``/dev/video0``).
|
|
|
|
``--tv-channel=<value>``
|
|
Set tuner to <value> channel.
|
|
|
|
``--no-tv-audio``
|
|
no sound
|
|
|
|
``--tv-automute=<0-255> (v4l and v4l2 only)``
|
|
If signal strength reported by device is less than this value, audio
|
|
and video will be muted. In most cases automute=100 will be enough.
|
|
Default is 0 (automute disabled).
|
|
|
|
``--tv-driver=<value>``
|
|
See ``--tv=driver=help`` for a list of compiled-in TV input drivers.
|
|
available: dummy, v4l2 (default: autodetect)
|
|
|
|
``--tv-input=<value>``
|
|
Specify input (default: 0 (TV), see console output for available
|
|
inputs).
|
|
|
|
``--tv-freq=<value>``
|
|
Specify the frequency to set the tuner to (e.g. 511.250). Not
|
|
compatible with the channels parameter.
|
|
|
|
``--tv-outfmt=<value>``
|
|
Specify the output format of the tuner with a preset value supported
|
|
by the V4L driver (YV12, UYVY, YUY2, I420) or an arbitrary format given
|
|
as hex value.
|
|
|
|
``--tv-width=<value>``
|
|
output window width
|
|
|
|
``--tv-height=<value>``
|
|
output window height
|
|
|
|
``--tv-fps=<value>``
|
|
framerate at which to capture video (frames per second)
|
|
|
|
``--tv-buffersize=<value>``
|
|
maximum size of the capture buffer in megabytes (default: dynamical)
|
|
|
|
``--tv-norm=<value>``
|
|
See the console output for a list of all available norms, also see the
|
|
``normid`` option below.
|
|
|
|
``--tv-normid=<value> (v4l2 only)``
|
|
Sets the TV norm to the given numeric ID. The TV norm depends on the
|
|
capture card. See the console output for a list of available TV norms.
|
|
|
|
``--tv-chanlist=<value>``
|
|
available: argentina, australia, china-bcast, europe-east,
|
|
europe-west, france, ireland, italy, japan-bcast, japan-cable,
|
|
newzealand, russia, southafrica, us-bcast, us-cable, us-cable-hrc
|
|
|
|
``--tv-channels=<chan>-<name>[=<norm>],<chan>-<name>[=<norm>],...``
|
|
Set names for channels.
|
|
|
|
.. note::
|
|
|
|
If <chan> is an integer greater than 1000, it will be treated as
|
|
frequency (in kHz) rather than channel name from frequency table.
|
|
Use _ for spaces in names (or play with quoting ;-) ). The channel
|
|
names will then be written using OSD, and the slave commands
|
|
``tv_step_channel``, ``tv_set_channel`` and ``tv_last_channel``
|
|
will be usable for a remote control. Not compatible with
|
|
the ``frequency`` parameter.
|
|
|
|
.. note::
|
|
|
|
The channel number will then be the position in the 'channels'
|
|
list, beginning with 1.
|
|
|
|
.. admonition:: Examples
|
|
|
|
``tv://1``, ``tv://TV1``, ``tv_set_channel 1``,
|
|
``tv_set_channel TV1``
|
|
|
|
``--tv-[brightness|contrast|hue|saturation]=<-100-100>``
|
|
Set the image equalizer on the card.
|
|
|
|
``--tv-audiorate=<value>``
|
|
Set input audio sample rate.
|
|
|
|
``--tv-forceaudio``
|
|
Capture audio even if there are no audio sources reported by v4l.
|
|
|
|
``--tv-alsa``
|
|
Capture from ALSA.
|
|
|
|
``--tv-amode=<0-3>``
|
|
Choose an audio mode:
|
|
|
|
:0: mono
|
|
:1: stereo
|
|
:2: language 1
|
|
:3: language 2
|
|
|
|
``--tv-forcechan=<1-2>``
|
|
By default, the count of recorded audio channels is determined
|
|
automatically by querying the audio mode from the TV card. This option
|
|
allows forcing stereo/mono recording regardless of the amode option
|
|
and the values returned by v4l. This can be used for troubleshooting
|
|
when the TV card is unable to report the current audio mode.
|
|
|
|
``--tv-adevice=<value>``
|
|
Set an audio device. <value> should be ``/dev/xxx`` for OSS and a
|
|
hardware ID for ALSA. You must replace any ':' by a '.' in the
|
|
hardware ID for ALSA.
|
|
|
|
``--tv-audioid=<value>``
|
|
Choose an audio output of the capture card, if it has more than one.
|
|
|
|
``--tv-[volume|bass|treble|balance]=<0-100>``
|
|
These options set parameters of the mixer on the video capture card.
|
|
They will have no effect, if your card does not have one. For v4l2 50
|
|
maps to the default value of the control, as reported by the driver.
|
|
|
|
``--tv-gain=<0-100>``
|
|
Set gain control for video devices (usually webcams) to the desired
|
|
value and switch off automatic control. A value of 0 enables automatic
|
|
control. If this option is omitted, gain control will not be modified.
|
|
|
|
``--tv-immediatemode=<bool>``
|
|
A value of 0 means capture and buffer audio and video together. A
|
|
value of 1 (default) means to do video capture only and let the audio
|
|
go through a loopback cable from the TV card to the sound card.
|
|
|
|
``--tv-mjpeg``
|
|
Use hardware MJPEG compression (if the card supports it). When using
|
|
this option, you do not need to specify the width and height of the
|
|
output window, because mpv will determine it automatically from
|
|
the decimation value (see below).
|
|
|
|
``--tv-decimation=<1|2|4>``
|
|
choose the size of the picture that will be compressed by hardware
|
|
MJPEG compression:
|
|
|
|
:1: full size
|
|
|
|
- 704x576 PAL
|
|
- 704x480 NTSC
|
|
|
|
:2: medium size
|
|
|
|
- 352x288 PAL
|
|
- 352x240 NTSC
|
|
|
|
:4: small size
|
|
|
|
- 176x144 PAL
|
|
- 176x120 NTSC
|
|
|
|
``--tv-quality=<0-100>``
|
|
Choose the quality of the JPEG compression (< 60 recommended for full
|
|
size).
|
|
|
|
``--tv-scan-autostart``
|
|
Begin channel scanning immediately after startup (default: disabled).
|
|
|
|
``--tv-scan-period=<0.1-2.0>``
|
|
Specify delay in seconds before switching to next channel (default:
|
|
0.5). Lower values will cause faster scanning, but can detect inactive
|
|
TV channels as active.
|
|
|
|
``--tv-scan-threshold=<1-100>``
|
|
Threshold value for the signal strength (in percent), as reported by
|
|
the device (default: 50). A signal strength higher than this value will
|
|
indicate that the currently scanning channel is active.
|
|
|
|
|
|
Cache
|
|
-----
|
|
|
|
``--cache=<kBytes|yes|no|auto>``
|
|
Set the size of the cache in kilobytes, disable it with ``no``, or
|
|
automatically enable it if needed with ``auto`` (default: ``auto``).
|
|
With ``auto``, the cache will usually be enabled for network streams,
|
|
using the size set by ``--cache-default``. With ``yes``, the cache will
|
|
always be enabled with the size set by ``--cache-default`` (unless the
|
|
stream can not be cached, or ``--cache-default`` disables caching).
|
|
|
|
May be useful when playing files from slow media, but can also have
|
|
negative effects, especially with file formats that require a lot of
|
|
seeking, such as MP4.
|
|
|
|
Note that half the cache size will be used to allow fast seeking back. This
|
|
is also the reason why a full cache is usually reported as 50% full. The
|
|
cache fill display does not include the part of the cache reserved for
|
|
seeking back. Likewise, when starting a file the cache will be at 100%,
|
|
because no space is reserved for seeking back yet.
|
|
|
|
``--cache-default=<kBytes|no>``
|
|
Set the size of the cache in kilobytes (default: 150000 KB). Using ``no``
|
|
will not automatically enable the cache e.g. when playing from a network
|
|
stream. Note that using ``--cache`` will always override this option.
|
|
|
|
``--cache-initial=<kBytes>``
|
|
Playback will start when the cache has been filled up with this many
|
|
kilobytes of data (default: 0).
|
|
|
|
``--cache-seek-min=<kBytes>``
|
|
If a seek is to be made to a position within ``<kBytes>`` of the cache
|
|
size from the current position, mpv will wait for the cache to be
|
|
filled to this position rather than performing a stream seek (default:
|
|
500).
|
|
|
|
This matters for small forward seeks. With slow streams (especially HTTP
|
|
streams) there is a tradeoff between skipping the data between current
|
|
position and seek destination, or performing an actual seek. Depending
|
|
on the situation, either of these might be slower than the other method.
|
|
This option allows control over this.
|
|
|
|
``--cache-file=<TMP|path>``
|
|
Create a cache file on the filesystem.
|
|
|
|
There are two ways of using this:
|
|
|
|
1. Passing a path (a filename). The file will always be overwritten. When
|
|
the general cache is enabled, this file cache will be used to store
|
|
whatever is read from the source stream.
|
|
|
|
This will always overwrite the cache file, and you can't use an existing
|
|
cache file to resume playback of a stream. (Technically, mpv wouldn't
|
|
even know which blocks in the file are valid and which not.)
|
|
|
|
The resulting file will not necessarily contain all data of the source
|
|
stream. For example, if you seek, the parts that were skipped over are
|
|
never read and consequently are not written to the cache. The skipped over
|
|
parts are filled with zeros. This means that the cache file doesn't
|
|
necessarily correspond to a full download of the source stream.
|
|
|
|
Both of these issues could be improved if there is any user interest.
|
|
|
|
.. warning:: Causes random corruption when used with ordered chapters or
|
|
with ``--audio-file``.
|
|
|
|
2. Passing the string ``TMP``. This will not be interpreted as filename.
|
|
Instead, an invisible temporary file is created. It depends on your
|
|
C library where this file is created (usually ``/tmp/``), and whether
|
|
filename is visible (the ``tmpfile()`` function is used). On some
|
|
systems, automatic deletion of the cache file might not be guaranteed.
|
|
|
|
If you want to use a file cache, this mode is recommended, because it
|
|
doesn't break ordered chapters or ``--audio-file``. These modes open
|
|
multiple cache streams, and using the same file for them obviously
|
|
clashes.
|
|
|
|
Also see ``--cache-file-size``.
|
|
|
|
``--cache-file-size=<kBytes>``
|
|
Maximum size of the file created with ``--cache-file``. For read accesses
|
|
above this size, the cache is simply not used.
|
|
|
|
Keep in mind that some use-cases, like playing ordered chapters with cache
|
|
enabled, will actually create multiple cache files, each of which will
|
|
use up to this much disk space.
|
|
|
|
(Default: 1048576, 1 GB.)
|
|
|
|
``--no-cache``
|
|
Turn off input stream caching. See ``--cache``.
|
|
|
|
``--cache-secs=<seconds>``
|
|
How many seconds of audio/video to prefetch if the cache is active. This
|
|
overrides the ``--demuxer-readahead-secs`` option if and only if the cache
|
|
is enabled and the value is larger. (Default: 10.)
|
|
|
|
``--cache-pause``, ``--no-cache-pause``
|
|
Whether the player should automatically pause when the cache runs low,
|
|
and unpause once more data is available ("buffering").
|
|
|
|
|
|
Network
|
|
-------
|
|
|
|
``--user-agent=<string>``
|
|
Use ``<string>`` as user agent for HTTP streaming.
|
|
|
|
``--cookies``, ``--no-cookies``
|
|
Support cookies when making HTTP requests. Disabled by default.
|
|
|
|
``--cookies-file=<filename>``
|
|
Read HTTP cookies from <filename>. The file is assumed to be in Netscape
|
|
format.
|
|
|
|
``--http-header-fields=<field1,field2>``
|
|
Set custom HTTP fields when accessing HTTP stream.
|
|
|
|
.. admonition:: Example
|
|
|
|
::
|
|
|
|
mpv --http-header-fields='Field1: value1','Field2: value2' \
|
|
http://localhost:1234
|
|
|
|
Will generate HTTP request::
|
|
|
|
GET / HTTP/1.0
|
|
Host: localhost:1234
|
|
User-Agent: MPlayer
|
|
Icy-MetaData: 1
|
|
Field1: value1
|
|
Field2: value2
|
|
Connection: close
|
|
|
|
``--tls-ca-file=<filename>``
|
|
Certificate authority database file for use with TLS. (Silently fails with
|
|
older FFmpeg or Libav versions.)
|
|
|
|
``--tls-verify``
|
|
Verify peer certificates when using TLS (e.g. with ``https://...``).
|
|
(Silently fails with older FFmpeg or Libav versions.)
|
|
|
|
``--referrer=<string>``
|
|
Specify a referrer path or URL for HTTP requests.
|
|
|
|
``--network-timeout=<seconds>``
|
|
Specify the network timeout in seconds. This affects at least HTTP. The
|
|
special value 0 (default) uses the FFmpeg/Libav defaults. If a protocol
|
|
is used which does not support timeouts, this option is silently ignored.
|
|
|
|
``--rtsp-transport=<lavf|udp|tcp|http>``
|
|
Select RTSP transport method (default: tcp). This selects the underlying
|
|
network transport when playing ``rtsp://...`` URLs. The value ``lavf``
|
|
leaves the decision to libavformat.
|
|
|
|
``--hls-bitrate=<no|min|max>``
|
|
If HLS streams are played, this option controls what streams are selected
|
|
by default. The option allows the following parameters:
|
|
|
|
:no: Don't do anything special. Typically, this will simply pick the
|
|
first audio/video streams it can find.
|
|
:min: Pick the streams with the lowest bitrate.
|
|
:max: Same, but highest bitrate. (Default.)
|
|
|
|
The bitrate as used is sent by the server, and there's no guarantee it's
|
|
actually meaningful.
|
|
|
|
DVB
|
|
---
|
|
|
|
``--dvbin-card=<1-4>``
|
|
Specifies using card number 1-4 (default: 1).
|
|
|
|
``--dvbin-file=<filename>``
|
|
Instructs mpv to read the channels list from ``<filename>``. The default is
|
|
in the mpv configuration directory (usually ``~/.config/mpv``) with the
|
|
filename ``channels.conf.{sat,ter,cbl,atsc}`` (based on your card type) or
|
|
``channels.conf`` as a last resort.
|
|
For DVB-S/2 cards, a VDR 1.7.x format channel list is recommended
|
|
as it allows tuning to DVB-S2 channels, enabling subtitles and
|
|
decoding the PMT (which largely improves the demuxing).
|
|
Classic mplayer format channel lists are still supported (without
|
|
these improvements), and for other card types, only limited VDR
|
|
format channel list support is implemented (patches welcome).
|
|
For channels with dynamic PID switching or incomplete
|
|
``channels.conf``, ``--dvbin-full-transponder`` or the magic PID
|
|
``8192`` are recommended.
|
|
|
|
``--dvbin-timeout=<1-30>``
|
|
Maximum number of seconds to wait when trying to tune a frequency before
|
|
giving up (default: 30).
|
|
|
|
``--dvbin-full-transponder=<yes|no>``
|
|
Apply no filters on program PIDs, only tune to frequency and pass full
|
|
transponder to demuxer. This is useful to record multiple programs
|
|
on a single transponder, or to work around issues in the ``channels.conf``.
|
|
It is also recommended to use this for channels which switch PIDs
|
|
on-the-fly, e.g. for regional news.
|
|
|
|
Default: ``no``
|
|
|
|
PVR
|
|
---
|
|
|
|
``--pvr-...``
|
|
These options tune various encoding properties of the PVR capture module.
|
|
It has to be used with any hardware MPEG encoder based card supported by
|
|
the V4L2 driver. The Hauppauge WinTV PVR-150/250/350/500 and all IVTV
|
|
based cards are known as PVR capture cards. Be aware that only Linux
|
|
2.6.18 kernel and above is able to handle MPEG stream through V4L2 layer.
|
|
For hardware capture of an MPEG stream and watching it with mpv, use
|
|
``pvr://`` as media URL.
|
|
|
|
|
|
``--pvr-aspect=<0-3>``
|
|
Specify input aspect ratio:
|
|
|
|
:0: 1:1
|
|
:1: 4:3 (default)
|
|
:2: 16:9
|
|
:3: 2.21:1
|
|
|
|
``--pvr-arate=<32000-48000>``
|
|
Specify encoding audio rate (default: 48000 Hz, available: 32000,
|
|
44100 and 48000 Hz).
|
|
|
|
``--pvr-alayer=<1-3>``
|
|
Specify MPEG audio layer encoding (default: 2).
|
|
|
|
``--pvr-abitrate=<32-448>``
|
|
Specify audio encoding bitrate in kbps (default: 384).
|
|
|
|
``--pvr-amode=<value>``
|
|
Specify audio encoding mode. Available preset values are 'stereo',
|
|
'joint_stereo', 'dual' and 'mono' (default: stereo).
|
|
|
|
``--pvr-vbitrate=<value>``
|
|
Specify average video bitrate encoding in Mbps (default: 6).
|
|
|
|
``--pvr-vmode=<value>``
|
|
Specify video encoding mode:
|
|
|
|
:vbr: Variable Bit Rate (default)
|
|
:cbr: Constant Bit Rate
|
|
|
|
``--pvr-vpeak=<value>``
|
|
Specify peak video bitrate encoding in Mbps (only useful for VBR
|
|
encoding, default: 9.6).
|
|
|
|
``--pvr-fmt=<value>``
|
|
Choose an MPEG format for encoding:
|
|
|
|
:ps: MPEG-2 Program Stream (default)
|
|
:ts: MPEG-2 Transport Stream
|
|
:mpeg1: MPEG-1 System Stream
|
|
:vcd: Video CD compatible stream
|
|
:svcd: Super Video CD compatible stream
|
|
:dvd: DVD compatible stream
|
|
|
|
|
|
Miscellaneous
|
|
-------------
|
|
|
|
``--display-tags=tag1,tags2,...``
|
|
Set the list of tags that should be displayed on the terminal. Tags that
|
|
are in the list, but are not present in the played file, will not be shown.
|
|
If a value ends with ``*``, all tags are matched by prefix (though there
|
|
is no general globbing). Just passing ``*`` essentially filtering.
|
|
|
|
The default includes a common list of tags, call mpv with ``--list-options``
|
|
to see it.
|
|
|
|
``--mc=<seconds/frame>``
|
|
Maximum A-V sync correction per frame (in seconds)
|
|
|
|
``--autosync=<factor>``
|
|
Gradually adjusts the A/V sync based on audio delay measurements.
|
|
Specifying ``--autosync=0``, the default, will cause frame timing to be
|
|
based entirely on audio delay measurements. Specifying ``--autosync=1``
|
|
will do the same, but will subtly change the A/V correction algorithm. An
|
|
uneven video framerate in a video which plays fine with ``--no-audio`` can
|
|
often be helped by setting this to an integer value greater than 1. The
|
|
higher the value, the closer the timing will be to ``--no-audio``. Try
|
|
``--autosync=30`` to smooth out problems with sound drivers which do not
|
|
implement a perfect audio delay measurement. With this value, if large A/V
|
|
sync offsets occur, they will only take about 1 or 2 seconds to settle
|
|
out. This delay in reaction time to sudden A/V offsets should be the only
|
|
side-effect of turning this option on, for all sound drivers.
|
|
|
|
``--mf-fps=<value>``
|
|
Framerate used when decoding from multiple PNG or JPEG files with ``mf://``
|
|
(default: 1).
|
|
|
|
``--mf-type=<value>``
|
|
Input file type for ``mf://`` (available: jpeg, png, tga, sgi). By default,
|
|
this is guessed from the file extension.
|
|
|
|
``--stream-capture=<filename>``
|
|
Allows capturing the primary stream (not additional audio tracks or other
|
|
kind of streams) into the given file. Capturing can also be started and
|
|
stopped by changing the filename with the ``stream-capture`` slave property.
|
|
Generally this will not produce usable results for anything else than MPEG
|
|
or raw streams, unless capturing includes the file headers and is not
|
|
interrupted. Note that, due to cache latencies, captured data may begin and
|
|
end somewhat delayed compared to what you see displayed.
|
|
|
|
The destination file is always appended. (Before mpv 0.8.0, the file was
|
|
overwritten.)
|
|
|
|
``--stream-dump=<filename>``
|
|
Same as ``--stream-capture``, but do not start playback. Instead, the entire
|
|
file is dumped.
|
|
|
|
``--stream-lavf-o=opt1=value1,opt2=value2,...``
|
|
Set AVOptions on streams opened with libavformat. Unknown or misspelled
|
|
options are silently ignored. (They are mentioned in the terminal output
|
|
in verbose mode, i.e. ``--v``. In general we can't print errors, because
|
|
other options such as e.g. user agent are not available with all protocols,
|
|
and printing errors for unknown options would end up being too noisy.)
|
|
|
|
``--priority=<prio>``
|
|
(Windows only.)
|
|
Set process priority for mpv according to the predefined priorities
|
|
available under Windows.
|
|
|
|
Possible values of ``<prio>``:

``--pts-association-mode=<decode|sort|auto>``
|
|
Select the method used to determine which container packet timestamp
|
|
corresponds to a particular output frame from the video decoder. Normally
|
|
you should not need to change this option.
|
|
|
|
:decoder: Use decoder reordering functionality. Unlike in classic MPlayer
|
|
and mplayer2, this includes a DTS fallback. (Default.)
|
|
:sort: Maintain a buffer of unused pts values and use the lowest value
|
|
for the frame.
|
|
:auto: Try to pick a working mode from the ones above automatically.
|
|
|
|
You can also try to use ``--no-correct-pts`` for files with completely
|
|
broken timestamps.
|
|
|
|
``--force-media-title=<string>``
|
|
Force the contents of the ``media-title`` property to this value. Useful
|
|
for scripts which want to set a title, without overriding the user's
|
|
setting in ``--title``.
