OPTIONS
=======
Track Selection
---------------
2013-07-08 16:02:14 +00:00
``--alang=<languagecode[,languagecode,...]>``
Specify a priority list of audio languages to use. Different container
2013-07-08 16:02:14 +00:00
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``.
2013-07-08 16:02:14 +00:00
.. admonition:: Examples
2013-07-08 16:02:14 +00:00
``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.
2013-07-08 16:02:14 +00:00
``--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.
2013-07-08 16:02:14 +00:00
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.
2013-07-08 16:02:14 +00:00
``--chapter=<start[-end]>``
Specify which chapter to start playing at. Optionally specify which
chapter to end playing at. Also see ``--start``.
``--playlist=<filename>``
2014-12-25 20:09:18 +00:00
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.
2014-09-01 02:25:57 +00:00
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.
2014-09-01 02:25:57 +00:00
Program Behavior
----------------
``--help``
Show short summary of options.
2013-07-08 16:02:14 +00:00
``-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.
2013-07-08 16:02:14 +00:00
.. 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.
2013-07-08 16:02:14 +00:00
.. 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.
2013-07-08 16:02:14 +00:00
``--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.
2014-11-19 17:51:53 +00:00
``--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.)
2014-11-19 17:51:53 +00:00
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.
2013-07-08 16:02:14 +00:00
``--untimed``
Do not sleep when outputting video frames. Useful for benchmarks when used
2013-07-08 16:02:14 +00:00
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>
2014-08-17 00:51:13 +00:00
Disable any framedropping.
<vo>
2014-08-17 00:51:13 +00:00
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
2014-08-20 14:44:19 +00:00
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
2015-01-01 21:54:26 +00:00
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 support This requires FFmpeg git master for accelerated hardware decoding. Keep in mind that FFmpeg must be compiled with --enable-mmal. Libav will also work. Most things work. Screenshots don't work with accelerated/opaque decoding (except using full window screenshot mode). Subtitles are very slow - even simple but huge overlays can cause frame drops. This always uses fullscreen mode. It uses dispmanx and mmal directly, and there are no window managers or anything on this level. vo_opengl also kind of works, but is pretty useless and slow. It can't use opaque hardware decoding (copy back can be used by forcing the option --vd=lavc:h264_mmal). Keep in mind that the dispmanx backend is preferred over the X11 ones in case you're trying on X11; but X11 is even more useless on RPI. This doesn't correctly reject extended h264 profiles and thus doesn't fallback to software decoding. The hw supports only up to the high profile, and will e.g. return garbage for Hi10P video. This sets a precedent of enabling hw decoding by default, but only if RPI support is compiled (which most hopefully it will be disabled on desktop Linux platforms). While it's more or less required to use hw decoding on the weak RPI, it causes more problems than it solves on real platforms (Linux has the Intel GPU problem, OSX still has some cases with broken decoding.) So I can live with this compromise of having different defaults depending on the platform. Raspberry Pi 2 is required. This wasn't tested on the original RPI, though at least decoding itself seems to work (but full playback was not tested).
2015-03-29 13:12:11 +00:00
: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,
2014-11-12 16:47:09 +00:00
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::
2013-04-20 21:23:09 +00:00
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``
2013-07-08 16:02:14 +00:00
``--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.
2013-07-08 16:02:14 +00:00
``--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.
core: add --deinterlace option, restore it with resume functionality The --deinterlace option does on playback start what the "deinterlace" property normally does at runtime. You could do this before by using the --vf option or by messing with the vo_vdpau default options, but this new option is supposed to be a "foolproof" way. The main motivation for adding this is so that the deinterlace property can be restored when using the video resume functionality (quit_watch_later command). Implementation-wise, this is a bit messy. The video chain is rebuilt in mpcodecs_reconfig_vo(), where we don't have access to MPContext, so the usual mechanism for enabling deinterlacing can't be used. Further, mpcodecs_reconfig_vo() is called by the video decoder, which doesn't have access to MPContext either. Moving this call to mplayer.c isn't currently possible either (see below). So we just do this before frames are filtered, which potentially means setting the deinterlacing every frame. Fortunately, setting deinterlacing is stable and idempotent, so this is hopefully not a problem. We also add a counter that is incremented on each reconfig to reduce the amount of additional work per frame to nearly zero. The reason we can't move mpcodecs_reconfig_vo() to mplayer.c is because of hardware decoding: we need to check whether the video chain works before we decide that we can use hardware decoding. Changing it so that this can be decided in advance without building a filter chain sounds like a good idea and should be done, but we aren't there yet.
2013-09-13 16:06:08 +00:00
``--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).
core: add --deinterlace option, restore it with resume functionality The --deinterlace option does on playback start what the "deinterlace" property normally does at runtime.

2013-09-13 16:06:08 +00:00
``--vd-lavc-skipframe=<skipvalue>``
Skips decoding of frames completely. Big speedup, but jerky motion and
sometimes bad artifacts (see skiploopfilter for available skip values).

2013-09-13 16:06:08 +00:00
``--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
2013-07-08 16:02:14 +00:00
``--ad=lavc:mp3float``
2014-09-01 02:25:57 +00:00
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
2015-03-30 17:44:52 +00:00
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.
2015-03-30 17:44:52 +00:00
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.
2014-10-26 11:02:00 +00:00
``--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.
2013-07-08 16:02:14 +00:00
.. 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.
2013-07-08 16:02:14 +00:00
.. 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.
2014-10-26 11:02:00 +00:00
``--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::
2013-07-08 16:02:14 +00:00
This affects ASS subtitles as well, and may lead to incorrect subtitle
rendering. Use with care, or use ``--sub-text-margin-y`` instead.
2013-07-08 16:02:14 +00:00
``--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``
2013-07-08 16:02:14 +00:00
.. note::
Using this option may lead to incorrect subtitle rendering.
2013-07-08 16:02:14 +00:00
2014-10-26 11:02:00 +00:00
``--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.
2013-07-08 16:02:14 +00:00
``--ass-line-spacing=<value>``
Set line spacing value for SSA/ASS renderer.
2013-07-08 16:02:14 +00:00
2014-10-26 11:02:00 +00:00
``--ass-shaper=<simple|complex>``
Set the text layout engine used by libass.
2013-07-08 16:02:14 +00:00
:simple: uses Fribidi only, fast, doesn't render some languages correctly
:complex: uses HarfBuzz, slower, wider language support
2013-07-08 16:02:14 +00:00
``complex`` is the default. If libass hasn't been compiled against HarfBuzz,
libass silently reverts to ``simple``.
2013-07-08 16:02:14 +00:00
``--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.
2013-07-08 16:02:14 +00:00
.. note::
2013-07-08 16:02:14 +00:00
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``.
2013-07-08 16:02:14 +00:00
``--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.
2013-07-08 16:02:14 +00:00
``--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.
2013-07-08 16:02:14 +00:00
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
2014-09-01 02:25:57 +00:00
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).
2014-09-01 02:25:57 +00:00
: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
2014-09-01 02:25:57 +00:00
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
2014-09-01 02:25:57 +00:00
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
2014-09-01 02:25:57 +00:00
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>``
2014-09-01 02:25:57 +00:00
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.
2013-07-08 16:02:14 +00:00
.. note::
Never applied to text subtitles.
2013-07-08 16:02:14 +00:00
``--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`_.)
2013-07-08 16:02:14 +00:00
.. 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.
2014-09-01 02:25:57 +00:00
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)
2014-09-01 02:25:57 +00:00
``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.
2014-12-12 23:14:07 +00:00
``--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.
2013-07-08 16:02:14 +00:00
.. 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::
2013-11-19 21:36:33 +00:00
Generally only supported by GUI VOs. Ignored for encoding.
2013-11-19 21:36:33 +00:00
.. admonition: Note (OS X)
2014-09-01 02:25:57 +00:00
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)
2013-07-08 16:02:14 +00:00
This option does not work properly with all window managers.
2013-07-08 16:02:14 +00:00
.. 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.
2013-07-08 16:02:14 +00:00
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
2013-07-08 16:02:14 +00:00
``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).
2013-07-08 16:02:14 +00:00
.. 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.)
osd: make the OSD and sub font more customizable Make more aspects of the OSD font customizable. This also affects the font used for unstyled subtitles (such as SRT), or when using the --no-ass option. This adds back some customizability that was lost with commit 74e7a1 (osd: use libass for OSD rendering). Removed options: --ass-border-color --ass-color --font --subfont --subfont-text-scale Added options: --osd-color --osd-border --osd-back-color --osd-shadow-color --osd-font --osd-font-size --osd-border-size --osd-margin-x --osd-margin-y --osd-shadow-offset --osd-spacing --sub-scale The font size is now specified in pixels as it would be rendered on a window with a height of 720 pixels. OSD and subtitles are always scaled with the window height, so specifying or expecting an absolute font size doesn't make sense. Such scaled pixel units are used to specify font border etc. as well. (Note: the font size is directly passed to libass. How the fonts are actually rasterized is outside of our control, but in theory ASS font sizes map to "script" pixels and then are scaled to screen size.) The default settings should be about the same, with slight difference due to rounding to the new scales. The OSD and subtitle fonts are not separately configurable.

``--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.

OSD and subtitles are always scaled with the window height, so specifying or expecting an absolute font size doesn't make sense. Such scaled pixel units are used to specify font border etc. as well. (Note: the font size is directly passed to libass. How the fonts are actually rasterized is outside of our control, but in theory ASS font sizes map to "script" pixels and then are scaled to screen size.) The default settings should be about the same, with slight difference due to rounding to the new scales. The OSD and subtitle fonts are not separately configurable.

``--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

``--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.
2012-12-21 19:36:08 +00:00
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 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.

``--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.

2012-11-17 19:56:45 +00:00
``--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.
2014-01-03 19:35:10 +00:00
``--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.
2013-07-08 16:02:14 +00:00
``--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
2014-11-19 17:27:53 +00:00
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>``
2014-09-01 02:25:57 +00:00
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
2013-07-08 16:02:14 +00:00
Play a raw YUV sample::
mpv sample-720x576.yuv --demuxer=rawvideo \
--demuxer-rawvideo-w=720 --demuxer-rawvideo-h=576
``--demuxer-rawvideo-format=<value>``
2014-09-01 02:25:57 +00:00
Color space (fourcc) in hex or string for ``--demuxer=rawvideo``
(default: ``YV12``).
``--demuxer-rawvideo-mp-format=<value>``
2014-09-01 02:25:57 +00:00
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.
2014-10-26 11:02:00 +00:00
``--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.)
2014-10-26 11:02:00 +00:00
``--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.
2014-10-26 11:02:00 +00:00
``--demuxer-readahead-bytes=<bytes>``
See ``--demuxer-readahead-packets``.
Input
-----
2013-07-08 16:02:14 +00:00
``--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.)
2013-07-08 16:02:14 +00:00
``--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``
2014-09-01 02:25:57 +00:00
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.
2013-07-08 16:02:14 +00:00
``--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.
2014-10-14 20:35:37 +00:00
``--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``.
2013-07-08 16:02:14 +00:00
.. admonition:: Examples
- ``--osd-font='Bitstream Vera Sans'``
- ``--osd-font='Bitstream Vera Sans:style=Bold'`` (fontconfig pattern)
2013-07-08 16:02:14 +00:00
.. 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`_.
2013-07-08 16:02:14 +00:00
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.
2014-09-01 22:09:03 +00:00
``--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.
2013-07-08 16:02:14 +00:00
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).
2013-08-15 19:45:40 +00:00
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.
2013-07-08 16:02:14 +00:00
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>``
2014-09-01 02:25:57 +00:00
OSD font size multiplier, multiplied with ``--osd-font-size`` value.
2014-10-26 11:02:00 +00:00
``--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.
2013-07-08 16:02:14 +00:00
``--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)
2013-07-08 16:02:14 +00:00
``--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
2014-09-01 02:25:57 +00:00
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.
2013-07-08 16:02:14 +00:00
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::
2013-07-08 16:02:14 +00:00
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``.
osd: make the OSD and sub font more customizable Make more aspects of the OSD font customizable. This also affects the font used for unstyled subtitles (such as SRT), or when using the --no-ass option. This adds back some customizability that was lost with commit 74e7a1 (osd: use libass for OSD rendering). Removed options: --ass-border-color --ass-color --font --subfont --subfont-text-scale Added options: --osd-color --osd-border --osd-back-color --osd-shadow-color --osd-font --osd-font-size --osd-border-size --osd-margin-x --osd-margin-y --osd-shadow-offset --osd-spacing --sub-scale The font size is now specified in pixels as it would be rendered on a window with a height of 720 pixels. OSD and subtitles are always scaled with the window height, so specifying or expecting an absolute font size doesn't make sense. Such scaled pixel units are used to specify font border etc. as well. (Note: the font size is directly passed to libass. How the fonts are actually rasterized is outside of our control, but in theory ASS font sizes map to "script" pixels and then are scaled to screen size.) The default settings should be about the same, with slight difference due to rounding to the new scales. The OSD and subtitle fonts are not separately configurable. It has limited use and would double the number of newly added options, which would be more confusing than helpful. It could be easily added later, should the need arise. Other small details that change: - ASS_Style.Encoding is not set to -1 for subs anymore (assuming subs use VSFilter direction in -no-ass mode too) - use a different WrapStyle for OSD - ASS forced styles are not applied to OSD
2012-11-17 19:56:45 +00:00
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)
2013-07-08 16:02:14 +00:00
``%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
2015-05-01 20:17:09 +00:00
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,
2013-07-08 16:02:14 +00:00
e.g. ``x11``. See also ``--vf=scale``.
To get a list of available scalers, run ``--sws-scaler=help``.
Default: ``bicubic``.
``--sws-lgb=<0-100>``
2014-09-01 02:25:57 +00:00
Software scaler Gaussian blur filter (luma). See ``--sws-scaler``.
``--sws-cgb=<0-100>``
2014-09-01 02:25:57 +00:00
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``.
2013-07-08 16:02:14 +00:00
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,
2014-09-01 02:25:57 +00:00
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
2013-07-08 16:02:14 +00:00
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
2013-07-08 16:02:14 +00:00
``--tv-channels=<chan>-<name>[=<norm>],<chan>-<name>[=<norm>],...``
Set names for channels.
2013-07-08 16:02:14 +00:00
.. note::
2013-07-08 16:02:14 +00:00
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
2014-09-01 02:25:57 +00:00
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).
2014-09-01 02:25:57 +00:00
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
-------
2013-07-08 16:02:14 +00:00
``--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
2013-07-08 16:02:14 +00:00
Will generate HTTP request::
GET / HTTP/1.0

``--tls-ca-file=<filename>``
Certificate authority database file for use with TLS. (Silently fails with
2014-09-01 02:25:57 +00:00
older FFmpeg or Libav versions.)
2013-07-08 16:02:14 +00:00
``--tls-verify``
Verify peer certificates when using TLS (e.g. with ``https://...``).
2014-09-01 02:25:57 +00:00
(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:
2014-09-01 02:25:57 +00:00
: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>``:
idle|belownormal|normal|abovenormal|high|realtime
.. warning:: Using realtime priority can cause system lockup.
``--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``.
