``--ad=<[+|-]family1:(*|decoder1),[+|-]family2:(*|decoder2),...[-]>``
|
|
Specify a priority list of audio decoders to be used, according to their
|
|
family and decoder name. Entries like ``family:*`` prioritize all decoders
|
|
of the given family. When determining which decoder to use, the first
|
|
decoder that matches the audio format is selected. If that is unavailable,
|
|
the next decoder is used. Finally, it tries all other decoders that are not
|
|
explicitly selected or rejected by the option.
|
|
|
|
``-`` at the end of the list suppresses fallback on other available
|
|
decoders not on the ``--ad`` list. ``+`` in front of an entry forces the
|
|
decoder. Both of these should not normally be used, because they break
|
|
normal decoder auto-selection!
|
|
|
|
``-`` in front of an entry disables selection of the decoder.
|
|
|
|
.. admonition:: Examples
|
|
|
|
``--ad=lavc:mp3float``
|
|
Prefer the FFmpeg/Libav ``mp3float`` decoder over all other mp3
|
|
decoders.
|
|
|
|
``--ad=spdif:ac3,lavc:*``
|
|
Always prefer spdif AC3 over FFmpeg/Libav over anything else.
|
|
|
|
``--ad=help``
|
|
List all available decoders.
|
|
|
|
``--ad-lavc-ac3drc=<level>``
|
|
Select the Dynamic Range Compression level for AC-3 audio streams.
|
|
``<level>`` is a float value ranging from 0 to 1, where 0 means no
|
|
compression and 1 (which is the default) means full compression (make loud
|
|
passages more silent and vice versa). Values up to 2 are also accepted, but
|
|
are purely experimental. This option only shows an effect if the AC-3 stream
|
|
contains the required range compression information.
|
|
|
|
``--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 ``--channels`` option.
|
|
Useful for playing surround audio on a stereo system.
|
|
|
|
``--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``
|
|
When using DTS passthrough, output any DTS-HD track as-is.
|
|
With ``ad-spdif-dtshd=no`` (the default), only the DTS Core parts will be
|
|
output.
|
|
|
|
DTS-HD tracks can be sent over HDMI but not over the original
|
|
coax/toslink S/PDIF system.
|
|
|
|
``--dtshd`` and ``--no-dtshd`` are deprecated aliases.
|
|
|
|
``--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.
|
|
|
|
``--aid=<ID|auto|no>``
|
|
Select audio channel. ``auto`` selects the default, ``no`` disables audio.
|
|
See also ``--alang``.
|
|
|
|
``--alang=<languagecode[,languagecode,...]>``
|
|
Specify a priority list of audio languages to use. Different container
|
|
formats employ different language codes. DVDs use ISO 639-1 two-letter
|
|
language codes, Matroska, MPEG-TS and NUT use ISO 639-2 three-letter
|
|
language codes, while OGM uses a free-form identifier. mpv prints the
|
|
available languages when run in verbose (``-v``) mode. See also ``--aid``.
|
|
|
|
.. admonition:: Examples
|
|
|
|
``mpv dvd://1 --alang=hu,en``
|
|
Chooses the Hungarian language track on a DVD and falls back on
|
|
English if Hungarian is not available.
|
|
``mpv --alang=jpn example.mkv``
|
|
Plays a Matroska file in Japanese.
|
|
|
|
``--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.
|
|
|
|
``--ar``, ``--no-ar``
|
|
Enable/disable AppleIR remote support. Enabled by default.
|
|
|
|
``--aspect=<ratio>``
|
|
Override movie aspect ratio, in case aspect information is incorrect or
|
|
missing in the file being played. See also ``--no-aspect``.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--aspect=4:3`` or ``--aspect=1.3333``
|
|
- ``--aspect=16:9`` or ``--aspect=1.7777``
|
|
|
|
``--ass``, ``--no-ass``
|
|
Render ASS subtitles natively (enabled by default).
|
|
|
|
If ``--no-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-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.
|
|
|
|
``--ass-force-style=<[Style.]Param=Value[,...]>``
|
|
Override some style or script info parameters.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--ass-force-style=FontName=Arial,Default.Bold=1``
|
|
- ``--ass-force-style=PlayResY=768``
|
|
|
|
.. note::
|
|
|
|
Using this option may lead to incorrect subtitle rendering.
|
|
|
|
``--ass-hinting=<type>``
|
|
Set font hinting type. <type> can be:
|
|
|
|
:0: no hinting
|
|
:1: FreeType autohinter, light mode
|
|
:2: FreeType autohinter, normal mode
|
|
:3: font native hinter
|
|
|
|
The default value is 0 (no hinting).
|
|
|
|
``--ass-line-spacing=<value>``
|
|
Set line spacing value for SSA/ASS renderer.
|
|
|
|
``--ass-styles=<filename>``
|
|
Load all SSA/ASS styles found in the specified file and use them for
|
|
rendering text subtitles. The syntax of the file is exactly like the ``[V4
|
|
Styles]`` / ``[V4+ Styles]`` section of SSA/ASS.
|
|
|
|
.. note::
|
|
|
|
Using this option may lead to incorrect subtitle rendering.
|
|
|
|
``--ass-style-override=<yes|no>``
|
|
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).
|
|
:no: Render subtitles as forced by subtitle scripts.
|
|
|
|
``--ass-use-margins``
|
|
Enables placing toptitles and subtitles in black borders when they are
|
|
available.
|
|
|
|
``--ass-vsfilter-aspect-compat``
|
|
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.
|
|
|
|
``--audio-demuxer=<[+]name>``
|
|
Use this audio demuxer type when using ``--audiofile``. Use a '+' before the
|
|
name to force it; this will skip some checks. Give the demuxer name as
|
|
printed by ``--audio-demuxer=help``.
|
|
|
|
``--audio-display=<no|attachment>``
|
|
Setting this option to ``attachment`` (default) will display image
|
|
attachments 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.
|
|
|
|
``--audiofile=<filename>``
|
|
Play audio from an external file (WAV, MP3 or Ogg Vorbis) while viewing a
|
|
movie.
|
|
|
|
``--audiofile-cache=<kBytes>``
|
|
Enables caching for the stream used by ``--audiofile``, using the
|
|
specified amount of memory.
|
|
|
|
``--autofit=<[W[xH]]>``
|
|
Set the initial window size to a maximum size specified by ``WxH``, without
|
|
changing the window's aspect ratio. The size is measured in pixels, or if
|
|
a number is followed by a percentage sign (``%``), in percents of the
|
|
screen size.
|
|
|
|
This option never changes the aspect ratio of the window. If the aspect
|
|
ratio mismatches, the window's size is reduced until it fits into the
|
|
specified size.
|
|
|
|
Window position is not taken into account, nor is it modified by this
|
|
option (the window manager still may place the window differently depending
|
|
on size). Use ``--geometry`` to change the window position. Its effects
|
|
are applied after this option.
|
|
|
|
See ``--geometry`` for details how this is handled with multi-monitor
|
|
setups.
|
|
|
|
Use ``--autofit-larger`` instead if you do not want the window to get
|
|
larger.
|
|
|
|
Use ``--geometry`` if you want to force both window width and height to a
|
|
specific size.
|
|
|
|
.. note::
|
|
|
|
Generally only supported by GUI VOs. Ignored for encoding.
|
|
|
|
.. admonition:: Examples
|
|
|
|
``70%``
|
|
Make the window width 70% of the screen size, keeping aspect ratio.
|
|
``1000``
|
|
Set the window width to 1000 pixels, keeping aspect ratio.
|
|
``70%:60%``
|
|
Make the window as large as possible, without being wider than 70%
|
|
of the screen width, or higher than 60% of the screen height.
|
|
|
|
``--autofit-larger=<[W[xH]]>``
|
|
This option behaves exactly like ``--autofit``, except the window size is
|
|
only changed if the window would be larger than the specified size.
|
|
|
|
.. admonition:: Example
|
|
|
|
``90%x80%``
|
|
If the video is larger than 90% of the screen width or 80% of the
|
|
screen height, make the window smaller until either its width is 90%
|
|
of the screen, or its height is 80% of the screen.
|
|
|
|
``--autosub``, ``--no-autosub``
|
|
Load additional subtitle files matching the video filename. Enabled by
|
|
default. See also ``--autosub-match``.
|
|
|
|
``--autosub-match=<exact|fuzzy|all>``
|
|
Adjust matching fuzziness when searching for subtitles:
|
|
|
|
:exact: exact match
|
|
:fuzzy: Load all subs containing movie name.
|
|
:all: Load all subs in the current and ``--sub-paths`` directories.
|
|
|
|
(default: exact)
|
|
|
|
``--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 movie 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.
|
|
|
|
``--bandwidth=<bytes>``
|
|
Specify the maximum bandwidth for network streaming (for servers that are
|
|
able to send content in different bitrates). Useful if you want to watch
|
|
live streamed media behind a slow connection. With Real RTSP streaming, it
|
|
is also used to set the maximum delivery bandwidth allowing faster cache
|
|
filling and stream dumping.
|
|
|
|
.. note::
|
|
|
|
Probably broken/useless.
|
|
|
|
``--untimed``
|
|
Do not sleep when outputting video frames. Useful for benchmarks when used
|
|
with ``--no-audio.``
|
|
|
|
``--bluray-angle=<ID>``
|
|
Some Blu-ray discs contain scenes that can be viewed from multiple angles.
|
|
This option tells mpv which angle to use (default: 1).
|
|
|
|
``--bluray-device=<path>``
|
|
(Blu-ray only)
|
|
Specify the Blu-ray disc location. Must be a directory with Blu-ray
|
|
structure.
|
|
|
|
``--border``, ``--no-border``
|
|
Play movie with window border and decorations. Since this is on by
|
|
default, use ``--no-border`` to disable the standard window decorations.
|
|
|
|
``--brightness=<-100-100>``
|
|
Adjust the brightness of the video signal (default: 0). Not supported by
|
|
all video output drivers.
|
|
|
|
``--cache=<kBytes|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 a default size.
|
|
|
|
May be useful when playing files from slow media, but can also have
|
|
negative effects, especially with file formats that require a lot of
|
|
seeking, such as mp4.
|
|
|
|
Note that half the cache size will be used to allow fast seeking back. This
|
|
is also the reason why a full cache is usually reported as 50% full. The
|
|
cache fill display does not include the part of the cache reserved for
|
|
seeking back. Likewise, when starting a file the cache will be at 100%,
|
|
because no space is reserved for seeking back yet.
|
|
|
|
``--cache-pause=<no|percentage>``
|
|
If the cache percentage goes below the specified value, pause and wait
|
|
until the percentage set by ``--cache-min`` is reached, then resume
|
|
playback (default: 10). If ``no`` is specified, this behavior is disabled.
|
|
|
|
When the player is paused this way, the status line shows ``Buffering``
|
|
instead of ``Paused``, and the OSD uses a clock symbol instead of the
|
|
normal paused symbol.
|
|
|
|
``--cache-min=<percentage>``
|
|
Playback will start when the cache has been filled up to ``<percentage>`` of
|
|
the total (default: 20).
|
|
|
|
``--cache-seek-min=<percentage>``
|
|
If a seek is to be made to a position within ``<percentage>`` 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:
|
|
50).
|
|
|
|
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.
|
|
|
|
``--cdda=<option1:option2>``
|
|
This option can be used to tune the CD Audio reading feature of mpv.
|
|
|
|
Available options are:
|
|
|
|
``speed=<value>``
|
|
Set CD spin speed.
|
|
|
|
``paranoia=<0-2>``
|
|
Set paranoia level. Values other than 0 seem to break playback of
|
|
anything but the first track.
|
|
|
|
:0: disable checking (default)
|
|
:1: overlap checking only
|
|
:2: full data correction and verification
|
|
|
|
``generic-dev=<value>``
|
|
Use specified generic SCSI device.
|
|
|
|
``sector-size=<value>``
|
|
Set atomic read size.
|
|
|
|
``overlap=<value>``
|
|
Force minimum overlap search during verification to <value> sectors.
|
|
|
|
``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.
|
|
|
|
``toc-offset=<value>``
|
|
Add ``<value>`` sectors to the values reported when addressing tracks.
|
|
May be negative.
|
|
|
|
``(no-)skip``
|
|
(Never) accept imperfect data reconstruction.
|
|
|
|
``--cdrom-device=<path>``
|
|
Specify the CD-ROM device (default: ``/dev/cdrom``).
|
|
|
|
``--channels=<number|layout>``
|
|
Request the number of playback channels (default: 2). mpv asks the
|
|
decoder to decode the audio into as many channels as specified. Then it is
|
|
up to the decoder to fulfill the requirement. This is usually only
|
|
important when playing videos with AC-3, AAC or DTS audio. In that case
|
|
libavcodec downmixes the audio into the requested number of channels if
|
|
possible.
|
|
|
|
.. note::
|
|
|
|
This option is honored by codecs (AC-3 only), filters (surround) and
|
|
audio output drivers (OSS at least).
|
|
|
|
The ``--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 ``--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).
|
|
|
|
``--chapter=<start[-end]>``
|
|
Specify which chapter to start playing at. Optionally specify which
|
|
chapter to end playing at. Also see ``--start``.
|
|
|
|
``--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.
|
|
|
|
``--colormatrix=<colorspace>``
|
|
Controls the YUV to RGB color space conversion when playing video. There
|
|
are various standards. Normally, BT.601 should be used for SD video, and
|
|
BT.709 for HD video. (This is done by default.) Using incorrect color space
|
|
results in slightly under or over saturated and shifted colors.
|
|
|
|
The color space conversion is additionally influenced by the related
|
|
options --colormatrix-input-range and --colormatrix-output-range.
|
|
|
|
These options are not always supported. Different video outputs provide
|
|
varying degrees of support. The ``opengl`` and ``vdpau`` video output
|
|
drivers usually offer full support. The ``xv`` output can set the color
|
|
space if the system video driver supports it, but not input and output
|
|
levels. The ``scale`` video filter can configure color space and input
|
|
levels, but only if the output format is RGB (if the video output driver
|
|
supports RGB output, you can force this with ``-vf scale,format=rgba``).
|
|
|
|
If this option is set to ``auto`` (which is the default), the video's
|
|
color space flag will be used. If that flag is unset, the color space
|
|
will be selected automatically. This is done using a simple heuristic that
|
|
attempts to distinguish SD and HD video. If the video is larger than
|
|
1279x576 pixels, BT.709 (HD) will be used; otherwise BT.601 (SD) is
|
|
selected.
|
|
|
|
Available color spaces are:
|
|
|
|
:auto: automatic selection (default)
|
|
:BT.601: ITU-R BT.601 (SD)
|
|
:BT.709: ITU-R BT.709 (HD)
|
|
:SMPTE-240M: SMPTE-240M
|
|
|
|
``--colormatrix-input-range=<color-range>``
|
|
YUV color levels used with YUV to RGB conversion. This option is only
|
|
necessary when playing broken files which do not follow standard color
|
|
levels or which are flagged wrong. If the video does not specify its
|
|
color range, it is assumed to be limited range.
|
|
|
|
The same limitations as with --colormatrix apply.
|
|
|
|
Available color ranges are:
|
|
|
|
:auto: automatic selection (normally limited range) (default)
|
|
:limited: limited range (16-235 for luma, 16-240 for chroma)
|
|
:full: full range (0-255 for both luma and chroma)
|
|
|
|
``--colormatrix-output-range=<color-range>``
|
|
RGB color levels used with YUV to RGB conversion. Normally, output devices
|
|
such as PC monitors use full range color levels. However, some TVs and
|
|
video monitors expect studio RGB levels. Providing full range output to a
|
|
device expecting studio level input results in crushed blacks and whites,
|
|
the reverse in dim grey blacks and dim whites.
|
|
|
|
The same limitations as with ``--colormatrix`` apply.
|
|
|
|
Available color ranges are:
|
|
|
|
:auto: automatic selection (equals to full range) (default)
|
|
:limited: limited range (16-235 per component), studio levels
|
|
:full: full range (0-255 per component), PC levels
|
|

|
It is advisable to use your graphics driver's color range option
|
|
instead, if available.
|
|
|
|
``--colorkey=<number>``
|
|
Changes the colorkey to an RGB value of your choice. ``0x000000`` is black
|
|
and ``0xffffff`` is white. Only supported by the ``xv`` (see
|
|
``--vo=xv:ck``) video output driver. See also ``--no-colorkey``.
|
|
|
|
``--consolecontrols``, ``--no-consolecontrols``
|
|
``--no-consolecontrols`` 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.
|
|
|
|
``--contrast=<-100-100>``
|
|
Adjust the contrast of the video signal (default: 0). Not supported by all
|
|
video output drivers.
|
|
|
|
``--cookies``, ``--no-cookies``
|
|
(network only)
|
|
Support cookies when making HTTP requests. Disabled by default.
|
|
|
|
``--cookies-file=<filename>``
|
|
(network only)
|
|
Read HTTP cookies from <filename>. The file is assumed to be in Netscape
|
|
format.
|
|
|
|
``--correct-pts``, ``--no-correct-pts``
|
|
Switches mpv to a mode where timestamps for video frames are calculated
|
|
differently and video filters which add new frames or modify timestamps of
|
|
existing ones are supported. Now enabled automatically for most common file
|
|
formats. The more accurate timestamps can be visible for example when
|
|
playing subtitles timed to scene changes with the ``--ass`` option. Without
|
|
``--correct-pts``, the subtitle timing will typically be off by some frames.
|
|
This option does not work correctly with some demuxers and codecs.
|
|
|
|
``--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.
|
|
|
|
``--audio-delay=<sec>``
|
|
Audio delay in seconds (positive or negative float value). Negative values
|
|
delay the audio, and positive values delay the video.
|
|
|
|
``--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=<value>``
|
|
Force a specific libavformat demuxer.
|
|
|
|
``--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-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.
|
|
|
|
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-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).
|
|
|
|
``--demuxer-rawaudio-rate=<value>``
|
|
Sample rate for ``--demuxer=rawaudio`` (default: 44KHz).
|
|
|
|
``--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
|
|
|
|
- ``mpv sample-720x576.yuv --demuxer=rawvideo --demuxer-rawvideo=w=720:h=576``
|
|
Play a raw YUV sample.
|
|
|
|
``--demuxer-rawvideo-format=<value>``
|
|
Colorspace (fourcc) in hex or string for ``--demuxer=rawvideo``
|
|
(default: YV12).
|
|
|
|
``--demuxer-rawvideo-mp-format=<value>``
|
|
Colorspace 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``.
|
|
|
|
``--doubleclick-time=<milliseconds>``
|
|
Time in milliseconds to recognize two consecutive button presses as a
|
|
double-click (default: 300).
|
|
|
|
``--dvbin=<options>``
|
|
Pass the following parameters to the DVB input module, in order to
|
|
override the default ones:
|
|
|
|
:card=<1-4>: Specifies using card number 1-4 (default: 1).
|
|
:file=<filename>: Instructs mpv to read the channels list from
|
|
``<filename>``. Default is
|
|
``~/.mpv/channels.conf.{sat,ter,cbl,atsc}`` (based
|
|
on your card type) or ``~/.mpv/channels.conf`` as a
|
|
last resort.
|
|
:timeout=<1-30>: Maximum number of seconds to wait when trying to tune a
|
|
frequency before giving up (default: 30).
|
|
|
|
``--dvd-device=<path>``
|
|
Specify the DVD device or .iso filename (default: ``/dev/dvd``). You can
|
|
also specify a directory that contains files previously copied directly
|
|
from a DVD (with e.g. vobcopy).
|
|
|
|
``--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.
|
|
|
|
``--dvdangle=<ID>``
|
|
Some DVDs contain scenes that can be viewed from multiple angles.
|
|
This option tells mpv which angle to use (default: 1).
|
|
|
|
``--edition=<ID>``
|
|
(Matroska files only)
|
|
Specify the edition (set of chapters) to use, where 0 is the first. If set
|
|
to -1 (the default), mpv will choose the first edition declared as a
|
|
default, or if there is no default, the first edition defined.
|
|
|
|
``--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
|
|
(``--ass`` option).
|
|
|
|
``--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.
|
|
|
|
``--field-dominance=<auto|top|bottom>``
|
|
Set first field for interlaced content. Useful for deinterlacers that
|
|
double the framerate: ``--vf=yadif=1`` 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
|
|
|
|
``--no-fixed-vo``, ``--fixed-vo``
|
|
``--no-fixed-vo`` enforces closing and reopening the video window for
|
|
multiple files (one (un)initialization for all files).
|
|
|
|
``--flip``
|
|
Flip image upside-down.
|
|
|
|
``--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.
|
|
|
|
``--sub-forced-only``
|
|
Display only forced subtitles for the DVD subtitle stream selected by e.g.
|
|
``--slang``.
|
|
|
|
``--forceidx``
|
|
Force index rebuilding. Useful for files with broken index (A/V desync,
|
|
etc). This will enable seeking in files where seeking was not possible.
|
|
|
|
.. note::
|
|
|
|
This option only works if the underlying media supports seeking
|
|
(i.e. not with stdin, pipe, etc).
|
|
|
|
``--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.
|
|
|
|
``--fps=<float>``
|
|
Override video framerate. Useful if the original value is wrong or missing.
|
|
|
|
.. note::
|
|
|
|
Works in ``--no-correct-pts`` mode only.
|
|
|
|
``--framedrop=<no|yes|hard>``
|
|
Skip displaying some frames to maintain A/V sync on slow systems. Video
|
|
filters are not applied to such frames. For B-frames even decoding is
|
|
skipped completely. May produce unwatchably choppy output. With ``hard``,
|
|
decoding and output of any frame can be skipped, and will lead to an even
|
|
worse playback experience.
|
|
|
|
.. note::
|
|
|
|
Practical use of this feature is questionable. Disabled by default.
|
|
|
|
``--frames=<number>``
|
|
Play/convert only first ``<number>`` video frames, then quit. For audio
|
|
only, run ``<number>`` iteration of the playback loop, which is most likely
|
|
not what you want. (This behavior also applies to the corner case when there
|
|
are fewer video frames than ``<number>``, and audio is longer than the
|
|
video.)
|
|
|
|
``--fullscreen``, ``--fs``
|
|
Fullscreen playback.
|
|
|
|
``--fs-screen=<all|current|0-32>``
|
|
In multi-monitor configurations (i.e. a single desktop that spans across
|
|
multiple displays), this option tells mpv which screen to go fullscreen to.
|
|
If ``default`` is provided mpv will fallback on using the behaviour
|
|
depending on what the user provided with the ``screen`` option.
|
|
|
|
.. admonition:: Note (X11)
|
|
|
|
This option does not work properly with all window managers.
|
|
``all`` in particular will usually only work with
|
|
``--fstype=-fullscreen`` or ``--fstype=none``, and even then only with
|
|
some window managers.
|
|
|
|
.. admonition:: Note (OS X)
|
|
|
|
``all`` does not work on OSX and will behave like ``current``.
|
|
|
|
See also ``--screen``.
|
|
|
|
``--fsmode-dontuse=<0-31>``
|
|
*OBSOLETE*, use the ``--fs`` option.
|
|
Try this option if you still experience fullscreen problems.
|
|
|
|
``--fstype=<type1,type2,...>``
|
|
(X11 only)
|
|
Specify a priority list of fullscreen modes to be used. You can negate the
|
|
modes by prefixing them with '-'. If you experience problems like the
|
|
fullscreen window being covered by other windows, try using a different
|
|
order.
|
|
|
|
.. note::
|
|
|
|
See ``--fstype=help`` for a full list of available modes.
|
|
|
|
The available types are:
|
|
|
|
above
|
|
Use the ``_NETWM_STATE_ABOVE`` hint if available.
|
|
below
|
|
Use the ``_NETWM_STATE_BELOW`` hint if available.
|
|
fullscreen
|
|
Use the ``_NETWM_STATE_FULLSCREEN`` hint if available.
|
|
layer
|
|
Use the ``_WIN_LAYER`` hint with the default layer.
|
|
layer=<0...15>
|
|
Use the ``_WIN_LAYER`` hint with the given layer number.
|
|
netwm
|
|
Force NETWM style.
|
|
none
|
|
Clear the list of modes; you can add modes to enable afterward.
|
|
stays_on_top
|
|
Use ``_NETWM_STATE_STAYS_ON_TOP`` hint if available.
|
|
|
|
.. admonition:: Examples
|
|
|
|
``--fstype=layer,stays_on_top,above,fullscreen``
|
|
Default order, will be used as a fallback if incorrect or
|
|
unsupported modes are specified.
|
|
``--fstype=fullscreen``
|
|
Fixes fullscreen switching on OpenBox 1.x.
|
|
|
|
``--native-fs``
|
|
(OS X only)
|
|
Use OS X Mission Control's fullscreen feature instead of the custom one
|
|
provided by mpv. This can potentially break a lot of stuff like
|
|
``--geometry`` and is disabled by default. On the other hand it provides
|
|
a more 'OS X-like' user experience.
|
|
|
|
``--gamma=<-100-100>``
|
|
Adjust the gamma of the video signal (default: 0). Not supported by all
|
|
video output drivers.
|
|
|
|
``--gapless-audio``
|
|
Try to play consecutive audio files with no silence or disruption at the
|
|
point of file change. 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.
|
|
|
|
.. note::
|
|
|
|
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 ``--srate`` and ``--format`` to
|
|
explicitly select what the shared output format will be.
|
|
|
|
``--geometry=<[W[xH]][+-x+-y]>``, ``--geometry=<x:y>``
|
|
Adjust the initial window position or size. ``W`` and ``H`` set the window
|
|
size in pixels. ``x`` and ``y`` set the window position, measured in pixels
|
|
from the top-left corner of the screen to the top-left corner of the image
|
|
being displayed. If a percentage sign (``%``) is given after the argument,
|
|
it turns the value into a percentage of the screen size in that direction.
|
|
Positions are specified similar to the standard X11 ``--geometry`` option
|
|
format, in which e.g. +10-50 means "place 10 pixels from the left border and
|
|
50 pixels from the lower border" and "--20+-10" means "place 20 pixels
|
|
beyond the right and 10 pixels beyond the top border".
|
|
|
|
If an external window is specified using the ``--wid`` option, this
|
|
option is ignored.
|
|
|
|
The coordinates are relative to the screen given with ``--screen`` for the
|
|
video output drivers that fully support ``--screen``.
|
|
|
|
.. note::
|
|
|
|
Generally only supported by GUI VOs. Ignored for encoding.
|
|
|
|
.. admonition: Note (OS X)
|
|
|
|
On Mac OSX the origin of the screen coordinate system is located on the
|
|
bottom-left corner. For instance, ``0:0`` will place the window at the
|
|
bottom-left of the screen.
|
|
|
|
.. admonition:: Note (X11)
|
|
|
|
This option does not work properly with all window managers.
|
|
|
|
.. admonition:: Examples
|
|
|
|
``50:40``
|
|
Places the window at x=50, y=40.
|
|
``50%:50%``
|
|
Places the window in the middle of the screen.
|
|
``100%:100%``
|
|
Places the window at the bottom right corner of the screen.
|
|
``50%``
|
|
Sets the window width to half the screen width. Window height is set
|
|
so that the window has the video aspect ratio.
|
|
``50%x50%``
|
|
Forces the window width and height to half the screen width and
|
|
height. Will show black borders to compensate for the video aspect
|
|
ration (with most VOs and without ``--no-keepaspect``).
|
|
``50%+10+10``
|
|
Sets the window to half the screen widths, and positions it 10
|
|
pixels below/left of the top left corner of the screen.
|
|
|
|
See also ``--autofit`` and ``--autofit-larger`` for fitting the window into
|
|
a given size without changing aspect ratio.
|
|
|
|
``--grabpointer``, ``--no-grabpointer``
|
|
``--no-grabpointer`` tells the player to not grab the mouse pointer after a
|
|
video mode change (``--vm``). Useful for multihead setups.
|
|
|
|
``--heartbeat-cmd``
|
|
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.
|
|
|
|
.. 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.

``--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

|
|
the default behavior of arrow keys (default).
|
|
:yes: Use precise seeks whenever possible.
|
|
|
|
``--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.
|
|
|
|
``--http-header-fields=<field1,field2>``
|
|
Set custom HTTP fields when accessing HTTP stream.
|
|
|
|
.. admonition:: Example
|
|
|
|
``mpv --http-header-fields='Field1: value1','Field2: value2' http://localhost:1234``
|
|
|
|
Will generate HTTP request::
|
|
|
|
GET / HTTP/1.0
|
|
Host: localhost:1234
|
|
User-Agent: MPlayer
|
|
Icy-MetaData: 1
|
|
Field1: value1
|
|
Field2: value2
|
|
Connection: close
|
|
|
|
``--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.
|
|
|
|
``--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)
|
|
:vdpau: works with nvidia drivers only, requires ``--vo=vdpau``
|
|
:vda: OSX
|
|
:crystalhd: Broadcom Crystal HD
|
|
|
|
``--hwdec-codecs=<codec1,codec2,...|all>``
|
|
Allow hardware decoding for a given list of codecs only. The default is the
|
|
special value ``all``, which always allows all codecs.
|
|
|
|
This is usually only needed with broken GPUs, where fallback on software
|
|
decoding does not work properly.
|
|
|
|
.. admonition:: Example
|
|
|
|
``mpv --hwdec=vdpau --vo=vdpau --hwdec-codecs=h264,mpeg2video``
|
|
Enable vdpau decoding for h264 and mpeg2 only.
|
|
|
|
``--identify``
|
|
Deprecated. Use ``TOOLS/mpv_identify.sh``.
|
|
|
|
``--idle``
|
|
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 (see also ``--slave-broken``).
|
|
|
|
``--idx``
|
|
Rebuilds index of files if no index was found, allowing seeking. Useful
|
|
with broken/incomplete downloads or badly created files. Now this is done
|
|
automatically by the demuxers used for most video formats, meaning that
|
|
this switch has no effect in the typical case. See also ``--forceidx``.
|
|
|
|
.. note::
|
|
|
|
This option only works if the underlying media supports seeking
|
|
(i.e. not with stdin, pipe, etc).
|
|
|
|
``--include=<configuration-file>``
|
|
Specify configuration file to be parsed after the default ones.
|
|
|
|
``--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.
|
|
|
|
``--input-conf=<filename>``
|
|
Specify input configuration file other than the default
|
|
``~/.mpv/input.conf``.
|
|
|
|
``--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.
|
|
|
|
``--no-input-default-bindings``
|
|
Disable mpv default (builtin) key bindings.
|
|
|
|
``--input-keylist``
|
|
Prints all keys that can be bound to commands.
|
|
|
|
``--input-cmdlist``
|
|
Prints all commands that can be bound to keys.
|
|
|
|
``--input-js-dev``
|
|
Specifies the joystick device to use (default: ``/dev/input/js0``).
|
|
|
|
``--input-file=<filename>``
|
|
Read commands from the given file. Mostly useful with a FIFO.
|
|
See also ``--slave-broken``.
|
|
|
|
.. note::
|
|
|
|
When the given file is a FIFO mpv opens both ends, so you can do several
|
|
`echo "seek 10" > mp_pipe` and the pipe will stay valid.
|
|
|
|
``--input-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`_.
|
|
|
|
``--joystick``, ``--no-joystick``
|
|
Enable/disable joystick support. Enabled by default.
|
|
|
|
``--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.)
|
|
|
|
``--keep-open``
|
|
Do not terminate when playing or seeking beyond the end of the file.
|
|
Instead, pause the player. When trying to seek beyond end of the file, the
|
|
player will pause at an arbitrary playback position (or, in corner cases,
|
|
not redraw the window at all).
|
|
|
|
.. note::
|
|
|
|
This option is not respected when using ``--frames``, ``--end``,
|
|
``--length``, or when passing a chapter range to ``--chapter``.
|
|
Explicitly skipping to the next file or skipping beyond the last
|
|
chapter will terminate playback as well, even if ``--keep-open`` is
|
|
given.
|
|
|
|
``--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.
|
|
|
|
``--length=<relative time>``
|
|
Stop after a given time relative to the start time.
|
|
See ``--start`` for valid option values and examples.
|
|
|
|
``--lirc``, ``--no-lirc``
|
|
Enable/disable LIRC support. Enabled by default.
|
|
|
|
``--lircconf=<filename>``
|
|
(LIRC only)
|
|
Specifies a configuration file for LIRC (default: ``~/.lircrc``).
|
|
|
|
``--list-options``
|
|
Prints all available options.
|
|
|
|
``--list-properties``
|
|
Print a list of the available properties.
|
|
|
|
``--loop=<number|inf|no>``
|
|
Loops playback ``<number>`` times. ``inf`` means forever and ``no`` disables
|
|
looping. If several files are specified on command line, the entire playlist
|
|
is looped.
|
|
|
|
``--mc=<seconds/frame>``
|
|
Maximum A-V sync correction per frame (in seconds)
|
|
|
|
``--media-keys``, ``--no-media-keys``
|
|
OSX only: Enabled by default. Enables/disable media keys support.
|
|
|
|
``--mf=<option1:option2:...>``
|
|
Used when decoding from multiple PNG or JPEG files with ``mf://``.
|
|
|
|
Available options are:
|
|
|
|
:fps=<value>: output fps (default: 25)
|
|
:type=<value>: input file type (available: jpeg, png, tga, sgi)
|
|
|
|
``--mixer=<device>``
|
|
Use a mixer device different from the default ``/dev/mixer``. For ALSA
|
|
this is the mixer name.
|
|
|
|
``--mixer-channel=<name[,index]>``
|
|
(``--ao=oss`` and ``--ao=alsa`` only)
|
|
This option will tell mpv to use a different channel for controlling
|
|
volume than the default PCM. Options for OSS include **vol, pcm, line**.
|
|
For a complete list of options look for ``SOUND_DEVICE_NAMES`` in
|
|
``/usr/include/linux/soundcard.h``. For ALSA, you can use the names e.g.
|
|
"``amixer scontrols``" displays, like **Master, Line, PCM**.
|
|
|
|
.. note::
|
|
|
|
ALSA mixer channel names followed by a number must be specified in the
|
|
<name,number> format, i.e. a channel labeled 'PCM 1' in alsamixer must
|
|
be converted to PCM,1.
|
|
|
|
``--monitoraspect=<ratio>``
|
|
Set the aspect ratio of your monitor or TV screen. A value of 0 disables a
|
|
previous setting (e.g. in the config file). Overrides the
|
|
``--monitorpixelaspect`` setting if enabled.
|
|
|
|
See also ``--monitorpixelaspect`` and ``--aspect``.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--monitoraspect=4:3`` or ``--monitoraspect=1.3333``
|
|
- ``--monitoraspect=16:9`` or ``--monitoraspect=1.7777``
|
|
|
|
``--monitorpixelaspect=<ratio>``
|
|
Set the aspect of a single pixel of your monitor or TV screen (default:
|
|
1). A value of 1 means square pixels (correct for (almost?) all LCDs). See
|
|
also ``--monitoraspect`` and ``--aspect``.
|
|
|
|
``--mouse-movements``
|
|
Permit mpv to receive pointer events reported by the video output
|
|
driver. Necessary to select the buttons in DVD menus. Supported for
|
|
X11-based VOs (x11, xv, etc) and the gl, direct3d and corevideo VOs.
|
|
|
|
``--mouseinput``, ``--no-mouseinput``
|
|
``--no-mouseinput`` disables mouse button press/release input.
|
|
|
|
``--no-msgcolor``
|
|
Disable colorful console output on terminals.
|
|
|
|
``--msglevel=<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.
|
|
|
|
See ``--msglevel=help`` for a list of all modules.
|
|
|
|
.. note::
|
|
|
|
Some messages are printed before the command line is parsed and are
|
|
therefore not affected by ``--msglevel``. To control these messages,
|
|
you have to use the ``MPV_VERBOSE`` environment variable; see
|
|
`ENVIRONMENT VARIABLES`_ for details.
|
|
|
|
Available levels:
|
|
|
|
:-1: complete silence
|
|
:0: fatal messages only
|
|
:1: error messages
|
|
:2: warning messages
|
|
:3: short hints
|
|
:4: informational messages
|
|
:5: status messages (default)
|
|
:6: verbose messages
|
|
:7: debug level 2
|
|
:8: debug level 3
|
|
:9: debug level 4
|
|
|
|
``--msgmodule``
|
|
Prepend module name in front of each console message.
|
|
|
|
``--mute=<auto|yes|no>``
|
|
Set startup audio mute status. ``auto`` (default) will not change the mute
|
|
status. Also see ``--volume``.
|
|
|
|
``--name``
|
|
Set the window class name for X11-based video output methods.
|
|
|
|
``--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.)
|
|
|
|
``--no-aspect``
|
|
Ignore aspect ratio information from video file and assume the video has
|
|
square pixels. See also ``--aspect``.
|
|
|
|
``--no-cache``
|
|
Turn off input stream caching. See ``--cache``.
|
|
|
|
``--no-colorkey``
|
|
Disables colorkeying. Only supported by the xv (see ``--vo=xv:ck``) video
|
|
output driver.
|
|
|
|
``--no-config``
|
|
Do not load default configuration files. This prevents loading of
|
|
``~/.mpv/config`` and ``~/.mpv/input.conf``, as well as loading the
|
|
same files from system wide configuration directories.
|
|
|
|
Loading of some configuration files is not affected by this option, such
|
|
as configuration files for DVB code and fontconfig.
|
|
|
|
.. note::
|
|
|
|
Files explicitly requested by command line options, like
|
|
``--include`` or ``--use-filedir-conf``, will still be loaded.
|
|
|
|
``--no-idx``
|
|
Do not use index present in the file even if one is present.
|
|
|
|
``--no-audio``
|
|
Do not play sound. With some demuxers this may not work. In those cases
|
|
you can try ``--ao=null`` instead.
|
|
|
|
``--no-resume-playback``
|
|
Do not restore playback position from ``~/.mpv/watch_later/``.
|
|
See ``quit_watch_later`` input command.
|
|
|
|
``--no-sub``
|
|
Do not select any subtitle when the file is loaded.
|
|
|
|
``--no-sub-visibility``
|
|
Disable display of subtitles, but still select and decode them.
|
|
|
|
``--no-video``
|
|
Do not play video. With some demuxers this may not work. In those cases
|
|
you can try ``--vo=null`` instead.
|
|
|
|
``--ontop``
|
|
Makes the player window stay on top of other windows. Supported by video
|
|
output drivers which use X11, as well as corevideo.
|
|
|
|
``--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.
|
|
|
|
``--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-bar-align-x=<-1-1>``
|
|
Position of the OSD bar. -1 is far left, 0 is centered, 1 is far right.
|
|
|
|
``--osd-bar-align-y=<-1-1>``
|
|
Position of the OSD bar. -1 is top, 0 is centered, 1 is bottom.
|
|
|
|
``--osd-bar-w=<1-100>``
|
|
Width of the OSD bar, in percentage of the screen width (default: 75).
|
|
A value of 0.5 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=<#RRGGBB>``, ``--sub-text-back-color=<#RRGGBB>``
|
|
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-border-color=<#RRGGBB>``, ``--sub-text-border-color=<#RRGGBB>``
|
|
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: 2.5.
|
|
|
|
``--osd-color=<#RRGGBB|#AARRGGBB>``, ``--sub-text-color=<#RRGGBB|#AARRGGBB>``
|
|
Specify the color used for OSD/unstyled text subtitles.
|
|
|
|
The color is specified as a RGB hex triplet, and 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.
|
|
|
|
You can specify transparency by specifying an alpha value in the form
|
|
``#AARRGGBB``. 0 is fully transparent, while ``FF`` is opaque (opaque is
|
|
default with the shorter color specification).
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--osd-color='#FF0000'`` set OSD to opaque red
|
|
- ``--osd-color='#C0808080'`` set OSD to 50% gray with 75% alpha
|
|
|
|
``--osd-duration=<time>``
|
|
Set the duration of the OSD messages in ms (default: 1000).
|
|
|
|
``--osd-font=<pattern>``, ``--sub-text-font=<pattern>``
|
|
Specify font to use for OSD and for subtitles that do not themselves
|
|
specify a particular font. The default is ``sans-serif``.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--osd-font='Bitstream Vera Sans'``
|
|
- ``--osd-font='Bitstream Vera Sans:style=Bold'`` (fontconfig pattern)
|
|
|
|
.. note::
|
|
|
|
The ``--sub-text-font`` option (and most other ``--sub-text-``
|
|
options) are ignored when ASS-subtitles are rendered, unless the
|
|
``--no-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: 45.
|
|
|
|
``--osd-fractions``
|
|
Show OSD times with fractions of seconds.
|
|
|
|
``--osd-level=<0-3>``
|
|
Specifies which mode the OSD should start in.
|
|
|
|
:0: subtitles only
|
|
:1: volume + seek (default)
|
|
:2: volume + seek + timer + percentage
|
|
:3: volume + seek + timer + percentage + total time
|
|
|
|
``--osd-margin-x=<size>, --sub-text-margin-x=<size>``
|
|
Left and right screen margin for the OSD/subs in scaled pixels (see
|
|
``--osd-font-size`` for details).
|
|
|
|
This option specifies the distance of the OSD to the left, as well as at
|
|
which distance from the right border long OSD text will be broken.
|
|
|
|
Default: 25.
|
|
|
|
``--osd-margin-y=<size>, --sub-text-margin-y=<size>``
|
|
Top and bottom screen margin for the OSD/subs in scaled pixels (see
|
|
``--osd-font-size`` for details).
|
|
|
|
This option specifies the vertical margins of the OSD. This is also used
|
|
for unstyled text subtitles. If you just want to raise the vertical
|
|
subtitle position, use ``--sub-pos``.
|
|
|
|
Default: 10.
|
|
|
|
``--osd-scale=<factor>``
|
|
OSD font size multiplicator, multiplied with ``--osd-font-size`` value.
|
|
|
|
``--osd-shadow-color=<#RRGGBB>, --sub-text-shadow-color=<#RRGGBB>``
|
|
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.
|
|
|
|
``--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`_.
|
|
|
|
``--panscan=<0.0-1.0>``
|
|
Enables pan-and-scan functionality (cropping the sides of e.g. a 16:9
|
|
movie 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.
|
|
|
|
``--panscanrange=<-19.0-99.0>``
|
|
(experimental)
|
|
Change the range of the pan-and-scan functionality (default: 1). Positive
|
|
values mean multiples of the default range. Negative numbers mean you can
|
|
zoom in up to a factor of ``--panscanrange=+1``. E.g. ``--panscanrange=-3``
|
|
allows a zoom factor of up to 4. This feature is experimental. Do not
|
|
report bugs unless you are using ``--vo=opengl``.
|
|
|
|
``--playing-msg=<string>``
|
|
Print out a string after starting playback. The string is expanded for
|
|
properties, e.g. ``--playing-msg=file: ${filename}`` will print the string
|
|
``file:`` followed by a space and the currently played filename.
|
|
|
|
See `Property Expansion`_.
|
|
|
|
``--status-msg=<string>``
|
|
Print out a custom string during playback instead of the standard status
|
|
line. Expands properties. See `Property Expansion`_.
|
|
|
|
``--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.
|
|
|
|
``--stream-dump=<filename>``
|
|
Same as ``--stream-capture``, but do not start playback. Instead, the entire
|
|
file is dumped.
|
|
|
|
``--playlist=<filename>``
|
|
Play files according to a playlist file (ASX, Winamp, SMIL, or
|
|
one-file-per-line format).
|
|
|
|
.. warning::
|
|
|
|
The way mpv parses and uses playlist files 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!
|
|
|
|
FIXME: This needs to be clarified and documented thoroughly.
|
|
|
|
``--pp=<quality>``
|
|
See also ``--vf=pp``.
|
|
|
|
``--pphelp``
|
|
See also ``--vf=pp``.
|
|
|
|
``--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.
|
|
|
|
``--profile=<profile1,profile2,...>``
|
|
Use the given profile(s), ``--profile=help`` displays a list of the
|
|
defined profiles.
|
|
|
|
``--pts-association-mode=<auto|decode|sort>``
|
|
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.
|
|
|
|
:auto: Try to pick a working mode from the ones below automatically
|
|
(default)
|
|
:decoder: Use decoder reordering functionality.
|
|
:sort: Maintain a buffer of unused pts values and use the lowest value
|
|
for the frame.
|
|
|
|
``--pvr=<option1:option2:...>``
|
|
This option tunes 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 a movie URL.
|
|
|
|
Available options are:
|
|
|
|
``aspect=<0-3>``
|
|
Specify input aspect ratio:
|
|
|
|
:0: 1:1
|
|
:1: 4:3 (default)
|
|
:2: 16:9
|
|
:3: 2.21:1
|
|
|
|
``arate=<32000-48000>``
|
|
Specify encoding audio rate (default: 48000 Hz, available: 32000,
|
|
44100 and 48000 Hz).
|
|
|
|
``alayer=<1-3>``
|
|
Specify MPEG audio layer encoding (default: 2).
|
|
|
|
``abitrate=<32-448>``
|
|
Specify audio encoding bitrate in kbps (default: 384).
|
|
|
|
``amode=<value>``
|
|
Specify audio encoding mode. Available preset values are 'stereo',
|
|
'joint_stereo', 'dual' and 'mono' (default: stereo).
|
|
|
|
``vbitrate=<value>``
|
|
Specify average video bitrate encoding in Mbps (default: 6).
|
|
|
|
``vmode=<value>``
|
|
Specify video encoding mode:
|
|
|
|
:vbr: Variable BitRate (default)
|
|
:cbr: Constant BitRate
|
|
|
|
``vpeak=<value>``
|
|
Specify peak video bitrate encoding in Mbps (only useful for VBR
|
|
encoding, default: 9.6).
|
|
|
|
``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
|
|
|
|
``--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``).
|
|
|
|
``--quvi-format=<best|default|...>``
|
|
Video format/quality that is directly passed to libquvi (default: ``best``).
|
|
This is used when opening links to streaming sites like YouTube. The
|
|
interpretation of this value is highly specific to the streaming site and
|
|
the video.
|
|
|
|
libquvi 0.4.x:
|
|
|
|
The only well-defined values that work on all sites are ``best``
|
|
(best quality/highest bandwidth, default), and ``default`` (lowest
|
|
quality).
|
|
|
|
The quvi command line tool can be used to find out which formats are
|
|
supported for a given URL: ``quvi --query-formats URL``.
|
|
|
|
libquvi 0.9.x:
|
|
|
|
The following explanations are relevant:
|
|
`<http://quvi.sourceforge.net/doc/0.9/glossary_termino.html#m_stream_id>`_
|
|
|
|
With 0.9.x, the ``quvi-format`` property can be used at runtime to cycle
|
|
through the list of formats. Unfortunately, this resets the playback
|
|
position and is slow too.
|
|
|
|
``--radio=<option1:option2:...>``
|
|
These options set various parameters of the radio capture module. For
|
|
listening to radio with mpv, use ``radio://<frequency>`` (if channels
|
|
option is not given) or ``radio://<channel_number>`` (if channels option
|
|
is given) as a movie URL. You can see allowed frequency range by running
|
|
mpv with ``-v``. To start the grabbing subsystem, use
|
|
``radio://<frequency or channel>/capture``. If the capture keyword is not
|
|
given, you can listen to radio using the line-in cable only. Using capture
|
|
to listen is not recommended due to synchronization problems, which makes
|
|
this process uncomfortable.
|
|
|
|
Available options are:
|
|
|
|
``device=<value>``
|
|
Radio device to use (default: ``/dev/radio0`` for Linux and
|
|
``/dev/tuner0`` for \*BSD).
|
|
|
|
``driver=<value>``
|
|
Radio driver to use (default: v4l2 if available, otherwise v4l).
|
|
Currently, v4l and v4l2 drivers are supported.
|
|
|
|
``volume=<0..100>``
|
|
Sound volume for radio device (default 100).
|
|
|
|
``channels=<frequency>-<name>,<frequency>-<name>,...``
|
|
Set channel list. Use _ for spaces in names (or play with quoting ;-) ).
|
|
The channel names will then be written using OSD, and the slave
|
|
commands ``radio_step_channel`` and ``radio_set_channel`` will be usable
|
|
for a remote control (see LIRC). If given, number in movie URL will be
|
|
treated as channel position in channel list.
|
|
|
|
.. admonition:: Example
|
|
|
|
``radio://1``, ``radio://104.4``, ``radio_set_channel 1``
|
|
|
|
``adevice=<value>`` (radio capture only)
|
|
Name of device to capture sound from. Without such a name, capture will
|
|
be disabled, even if the ``capture`` keyword appears in the URL.
|
|
For ALSA devices, use it in the form ``hw=<card>.<device>``. If the
|
|
device name contains a '=', the module will use ALSA to capture,
|
|
otherwise OSS.
|
|
|
|
``arate=<value>`` (radio capture only)
|
|
Rate in samples per second (default: 44100).
|
|
|
|
.. note::
|
|
|
|
When using audio capture set also ``--rawaudio=rate=<value>`` option
|
|
with the same value as arate. If you have problems with sound speed
|
|
(runs too quickly), try to play with different rate values (e.g.
|
|
48000, 44100, 32000,...).
|
|
|
|
``achannels=<value>`` (radio capture only)
|
|
Number of audio channels to capture.
|
|
|
|
``--really-quiet``
|
|
Display even less output and status messages than with ``--quiet``.
|
|
|
|
``--referrer=<string>``
|
|
Specify a referrer path or URL for HTTP requests.
|
|
|
|
``--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: ``--reset-on-next-file=pause`` (only the pause mode is reset).
|
|
|
|
This can be changed with this option. It accepts a list of options, and
|
|
mpv will reset the value of these options on playback start to the initial
|
|
value. The initial value is either the default value, or as set by the
|
|
config file or command line.
|
|
|
|
In some cases, this might not work as expected. For example, ``--volume``
|
|
will only be reset if it is explicitly set in the config file or the
|
|
command line.
|
|
|
|
The special name ``all`` resets as many options as possible.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--reset-on-next-file=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.
|
|
- ``--reset-on-next-file=""``
|
|
Do not reset pause mode.
|
|
|
|
``--reuse-socket``
|
|
(udp:// only)
|
|
Allows a socket to be reused by other processes as soon as it is closed.
|
|
|
|
``--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.
|
|
|
|
``--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 affects any form of stopping playback (quitting, going to the
|
|
next file).
|
|
|
|
This behavior is disabled by default, but is always available when quitting
|
|
the player with Shift+Q.
|
|
|
|
``--sb=<n>``
|
|
Seek to byte position. Useful for playback from CD-ROM images or VOB files
|
|
with junk at the beginning. See also ``--start``.
|
|
|
|
``--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
|
|
movie on.
|
|
|
|
This option does not always work. In these cases, try to use ``--geometry``
|
|
to position the window explicitly.
|
|
|
|
.. admonition:: Note (X11)
|
|
|
|
This option does not work properly with all window managers.
|
|
|
|
See also ``--fs-screen``.
|
|
|
|
``--screenshot-format=<type>``
|
|
Set the image file type used for saving screenshots.
|
|
|
|
Available choices:
|
|
|
|
:png: PNG
|
|
:ppm: PPM
|
|
:pgm: PGM
|
|
:pgmyuv: PGM with YV12 pixel format
|
|
:tga: TARGA
|
|
:jpg: JPEG (default)
|
|
:jpeg: JPEG (same as jpg, but with .jpeg file ending)
|
|
|
|
``--screenshot-jpeg-quality=<0-100>``
|
|
Set the JPEG quality level. Higher means better quality. The default is 90.
|
|
|
|
``--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.
|
|
|
|
``--screenshot-template=<template>``
|
|
Specify the filename template used to save screenshots. The template
|
|
specifies the filename without file extension, and can contain format
|
|
specifiers, which will be substituted when taking a screeshot.
|
|
By default the template is ``shot%n``, which results in filenames like
|
|
``shot0012.png`` for example.
|
|
|
|
The template can start with a relative or absolute path, in order to
|
|
specify a directory location where screenshots should be saved.
|
|
|
|
If the final screenshot filename points to an already existing file, the
|
|
file will not be overwritten. The screenshot will either not be saved, or if
|
|
the template contains ``%n``, saved using different, newly generated
|
|
filename.
|
|
|
|
Allowed format specifiers:
|
|
|
|
``%[#][0X]n``
|
|
A sequence number, padded with zeros to length X (default: 04). E.g.
|
|
passing the format ``%04n`` will yield ``0012`` on the 12th screenshot.
|
|
The number is incremented every time a screenshot is taken or if the
|
|
file already exists. The length ``X`` must be in the range 0-9. With
|
|
the optional # sign, mpv will use the lowest available number. For
|
|
example, if you take three screenshots--0001, 0002, 0003--and delete
|
|
the first two, the next two screenshots will not be 0004 and 0005, but
|
|
0001 and 0002 again.
|
|
``%f``
|
|
Filename of the currently played video.
|
|
``%F``
|
|
Same as ``%f``, but strip the file extension, including the dot.
|
|
``%p``
|
|
Current playback time, in the same format as used in the OSD. The
|
|
result is a string of the form "HH:MM:SS". For example, if the video is
|
|
at the time position 5 minutes and 34 seconds, ``%p`` will be replaced
|
|
with "00:05:34".
|
|
``%P``
|
|
Similar to ``%p``, but extended with the playback time in milliseconds.
|
|
It is formatted as "HH:MM:SS.mmm", with "mmm" being the millisecond
|
|
part of the playback time.
|
|
|
|
.. note::
|
|
|
|
This is a simple way for getting unique per-frame timestamps. Frame
|
|
numbers would be more intuitive, but are not easily implementable
|
|
because container formats usually use time stamps for identifying
|
|
frames.)
|
|
``%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.
|
|
|
|
``--screenh=<pixels>``
|
|
Specify the screen height for video output drivers which do not know the
|
|
screen resolution, like ``x11`` and TV-out.
|
|
|
|
``--screenw=<pixels>``
|
|
Specify the screen width for video output drivers which do not know the
|
|
screen resolution, like ``x11`` and TV-out.
|
|
|
|
``--show-profile=<profile>``
|
|
Show the description and content of a profile.
|
|
|
|
``--shuffle``
|
|
Play files in random order.
|
|
|
|
``--sid=<ID|auto|no>``
|
|
Display the subtitle stream specified by ``<ID>`` (0-31). ``auto`` selects
|
|
the default, ``no`` disables subtitles.
|
|
|
|
See also ``--slang``, ``--no-sub``.
|
|
|
|
``--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. mpv prints the available languages
|
|
when run in verbose (``-v``) mode. 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.
|
|
|
|
``--slave-broken``
|
|
Switches on the old slave mode. This is for testing only, and incompatible
|
|
to the removed ``--slave`` switch.
|
|
|
|
.. attention::
|
|
Changes incompatible to slave mode applications have been made. In
|
|
particular, the status line output was changed, which is used by some
|
|
applications to determine the current playback position. This switch
|
|
has been renamed to prevent these applications from working with this
|
|
version of mpv, because it would lead to buggy and confusing behavior
|
|
only. Moreover, the slave mode protocol is so horribly bad that it
|
|
should not be used for new programs, nor should existing programs
|
|
attempt to adapt to the changed output and use the ``--slave-broken``
|
|
switch. Instead, a new, saner protocol should be developed (and will be,
|
|
if there is enough interest).
|
|
|
|
This affects most third-party GUI frontends.
|
|
|
|
``--softsleep``
|
|
Time frames by repeatedly checking the current time instead of asking
|
|
the kernel to wake up mpv at the correct time. Useful if your kernel
|
|
timing is imprecise and you cannot use the RTC either. Comes at the
|
|
price of higher CPU consumption.
|
|
|
|
``--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.
|
|
|
|
``--softvol-max=<10.0-10000.0>``
|
|
Set the maximum amplification level in percent (default: 200). A value of
|
|
200 will allow you to adjust the volume up to a maximum of double the
|
|
current level. With values below 100 the initial volume (which is 100%)
|
|
will be above the maximum, which e.g. the OSD cannot display correctly.
|
|
|
|
``--speed=<0.01-100>``
|
|
Slow down or speed up playback by the factor given as parameter.
|
|
|
|
``--srate=<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.
|
|
|
|
``--start=<relative time>``
|
|
Seek to given time position.
|
|
|
|
The general format for absolute times is ``[[hh:]mm:]ss[.ms]``. If the time
|
|
is negated with ``-``, the seek is relative from the 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``
|
|
Seeks to 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.
|
|
|
|
``--ssf=<mode>``
|
|
Specifies software scaler parameters.
|
|
|
|
:lgb=<0-100>: gaussian blur filter (luma)
|
|
:cgb=<0-100>: gaussian blur filter (chroma)
|
|
:ls=<-100-100>: sharpen filter (luma)
|
|
:cs=<-100-100>: sharpen filter (chroma)
|
|
:chs=<h>: chroma horizontal shifting
|
|
:cvs=<v>: chroma vertical shifting
|
|
|
|
.. admonition:: Example
|
|
|
|
``--vf=scale --ssf=lgb=3.0``
|
|
|
|
``--sstep=<sec>``
|
|
Skip <sec> seconds after every frame.
|
|
|
|
.. note::
|
|
|
|
Without ``--hr-seek``, skipping will snap to keyframes.
|
|
|
|
``--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).
|
|
|
|
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.
|
|
|
|
``--sub=<subtitlefile1,subtitlefile2,...>``
|
|
Use/display these subtitle files. Only one file can be displayed at the
|
|
same time.
|
|
|
|
``--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-demuxer=<[+]name>``
|
|
Force subtitle demuxer type for ``--sub``. Give the demuxer name as
|
|
printed by ``--sub-demuxer=help``.
|
|
|
|
``--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/movie/movie.avi`` is played and
|
|
``--sub-paths=sub:subtitles:/tmp/subs`` is specified, mpv searches for
|
|
subtitle files in these directories:
|
|
|
|
- ``/path/to/movie/``
|
|
- ``/path/to/movie/sub/``
|
|
- ``/path/to/movie/subtitles/``
|
|
- ``/tmp/subs/``
|
|
- ``~/.mpv/sub/``
|
|
|
|
``--subcp=<codepage>``
|
|
If your system supports ``iconv(3)``, you can use this option to specify
|
|
the subtitle codepage.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--subcp=latin2``
|
|
- ``--subcp=cp1250``
|
|
|
|
If the player was compiled with ENCA support, you can use special syntax
|
|
to use that::
|
|
|
|
--subcp=enca:<language>:<fallback codepage>
|
|
|
|
You can specify your language using a two letter language code to make
|
|
ENCA detect the codepage automatically. If unsure, enter anything (if the
|
|
language is invalid, mpv will complain and list valid languages).
|
|
Fallback codepage specifies the codepage to use if autodetection fails.
|
|
|
|
.. admonition:: Examples
|
|
|
|
- ``--subcp=enca:cs:latin2`` guess the encoding, assuming the subtitles
|
|
are Czech, fall back on latin 2, if the detection fails.
|
|
- ``--subcp=enca:pl:cp1250`` guess the encoding for Polish, fall back on
|
|
cp1250.
|
|
- ``--subcp=enca:pl`` guess the encoding for Polish, fall back on UTF-8.
|
|
- ``--subcp=enca`` try universal detection, fall back on UTF-8.
|
|
|
|
If the player was compiled with libguess support, you can use it with:
|
|
|
|
``--subcp=guess:<language>:<fallback codepage>``
|
|
|
|
Note that libguess always needs a language. There is no universal detection
|
|
mode. Use ``--subcp=guess:help`` to get a list of languages (like with ENCA,
|
|
it will be printed only if the conversion code is somehow called, for
|
|
example when loading an external subtitle).
|
|
|
|
``--sub-delay=<sec>``
|
|
Delays subtitles by ``<sec>`` seconds. Can be negative.
|
|
|
|
``--subfps=<rate>``
|
|
Specify the framerate of the subtitle file (default: movie fps).
|
|
|
|
.. note::
|
|
|
|
``<rate>`` > movie fps speeds the subtitles up for frame-based
|
|
subtitle files and slows them down for time-based ones.
|
|
|
|
Also see ``--sub-speed`` option.
|
|
|
|
``--sub-gauss=<0.0-3.0>``
|
|
Apply gaussian blur to image subtitles (default: 0). This can help making
|
|
pixelated DVD/Vobsubs look nicer. A value other than 0 also switches to
|
|
software subtitle scaling. Might be slow.
|
|
|
|
.. note::
|
|
|
|
Never applied to text subtitles.
|
|
|
|
``--sub-gray``
|
|
Convert image subtitles to grayscale. Can help making yellow DVD/Vobsubs
|
|
look nicer.
|
|
|
|
.. note::
|
|
|
|
Never applied to text subtitles.
|
|
|
|
``--sub-pos=<0-100>``
|
|
Specify the position of subtitles on the screen. The value is the vertical
|
|
position of the subtitle in % of the screen height.
|
|
|
|
.. note::
|
|
|
|
This affects ASS subtitles as well, and may lead to incorrect subtitle
|
|
rendering. Use with care, or use ``--sub-text-margin-y`` instead.
|
|
|
|
``--sub-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-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:: Examples
|
|
|
|
- ``--sub-speed=25/23.976`` plays frame based subtitles which have been
|
|
loaded assuming a framerate of 23.976 at 25 FPS.
|
|
|
|
``--sws=<n>``
|
|
Specify the software scaler algorithm to be used with ``--vf=scale``. This
|
|
also affects video output drivers which lack hardware acceleration,
|
|
e.g. ``x11``. See also ``--vf=scale``.
|
|
|
|
Available types are:
|
|
|
|
:0: fast bilinear
|
|
:1: bilinear
|
|
:2: bicubic (good quality) (default)
|
|
:3: experimental
|
|
:4: nearest neighbor (bad quality)
|
|
:5: area
|
|
:6: luma bicubic / chroma bilinear
|
|
:7: gauss
|
|
:8: sincR
|
|
:9: lanczos
|
|
:10: natural bicubic spline
|
|
|
|
.. note::
|
|
|
|
Some ``--sws`` options are tunable. The description of the ``scale``
|
|
video filter has further information.
|
|
|
|
``--term-osd, --no-term-osd``
|
|
Display OSD messages on the console when no video output is available.
|
|
Enabled by default.
|
|
|
|
``--term-osd-esc=<string>``
|
|
Specify the escape sequence to use before writing an OSD message on the
|
|
console. The escape sequence should move the pointer to the beginning of
|
|
the line used for the OSD and clear it (default: ``^[[A\r^[[K``).
|
|
|
|
``--title=<string>``
|
|
Set the window title. Properties are expanded on playback start.
|
|
(See `Property Expansion`_.)
|
|
|
|
.. warning::
|
|
|
|
There is a danger of this causing significant CPU usage, depending on
|
|
the properties used and the window manager.
|
|
|
|
``--tv=<option1:option2:...>``
|
|
This option tunes 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 ``channels`` for ``channel_name``
|
|
below) as a movie URL. You can also use ``tv:///<input_id>`` to start
|
|
watching a movie from a composite or S-Video input (see option ``input`` for
|
|
details).
|
|
|
|
Available options are:
|
|
|
|
``noaudio``
|
|
no sound
|
|
|
|
``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).
|
|
|
|
``driver=<value>``
|
|
See ``--tv=driver=help`` for a list of compiled-in TV input drivers.
|
|
available: dummy, v4l2 (default: autodetect)
|
|
|
|
``device=<value>``
|
|
Specify TV device (default: ``/dev/video0``).
|
|
|
|
``input=<value>``
|
|
Specify input (default: 0 (TV), see console output for available
|
|
inputs).
|
|
|
|
``freq=<value>``
|
|
Specify the frequency to set the tuner to (e.g. 511.250). Not
|
|
compatible with the channels parameter.
|
|
|
|
``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.
|
|
|
|
``width=<value>``
|
|
output window width
|
|
|
|
``height=<value>``
|
|
output window height
|
|
|
|
``fps=<value>``
|
|
framerate at which to capture video (frames per second)
|
|
|
|
``buffersize=<value>``
|
|
maximum size of the capture buffer in megabytes (default: dynamical)
|
|
|
|
``norm=<value>``
|
|
See the console output for a list of all available norms, also see the
|
|
``normid`` option below.
|
|
|
|
``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.
|
|
|
|
``channel=<value>``
|
|
Set tuner to <value> channel.
|
|
|
|
``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
|
|
|
|
``channels=<chan>-<name>[=<norm>],<chan>-<name>[=<norm>],...``
|
|
Set names for channels.
|
|
|
|
.. note::
|
|
|
|
If <chan> is an integer greater than 1000, it will be treated as
|
|
frequency (in kHz) rather than channel name from frequency table.
|
|
Use _ for spaces in names (or play with quoting ;-) ). The channel
|
|
names will then be written using OSD, and the slave commands
|
|
``tv_step_channel``, ``tv_set_channel`` and ``tv_last_channel``
|
|
will be usable for a remote control (see LIRC). 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``
|
|
|
|
``[brightness|contrast|hue|saturation]=<-100-100>``
|
|
Set the image equalizer on the card.
|
|
|
|
``audiorate=<value>``
|
|
Set input audio sample rate.
|
|
|
|
``forceaudio``
|
|
Capture audio even if there are no audio sources reported by v4l.
|
|
|
|
``alsa``
|
|
Capture from ALSA.
|
|
|
|
``amode=<0-3>``
|
|
Choose an audio mode:
|
|
|
|
:0: mono
|
|
:1: stereo
|
|
:2: language 1
|
|
:3: language 2
|
|
|
|
``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.
|
|
|
|
``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.
|
|
|
|
``audioid=<value>``
|
|
Choose an audio output of the capture card, if it has more than one.
|
|
|
|
``[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.
|
|
|
|
``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.
|
|
|
|
``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.
|
|
|
|
``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).
|
|
|
|
``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
|
|
|
|
``quality=<0-100>``
|
|
Choose the quality of the JPEG compression (< 60 recommended for full
|
|
size).
|
|
|
|
``--tvscan=<option1:option2:...>``
|
|
Tune the TV channel scanner. mpv will also print value for
|
|
``--tv=channels=`` option, including existing and just found channels.
|
|
|
|
Available suboptions are:
|
|
|
|
``autostart``
|
|
Begin channel scanning immediately after startup (default: disabled).
|
|
|
|
``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.
|
|
|
|
``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.
|
|
|
|
``--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.
|
|
|
|
``--user-agent=<string>``
|
|
Use ``<string>`` as user agent for HTTP streaming.
|
|
|
|
``-v``
|
|
Increment verbosity level, one level for each ``-v`` found on the command
|
|
line.
|
|
|
|
``--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.
|
|
|
|
``--vd-lavc-bitexact``
|
|
Only use bit-exact algorithms in all decoding steps (for codec testing).
|
|
|
|
``--vd-lavc-fast`` (MPEG-2, MPEG-4, and H.264 only)
|
|
Enable optimizations which do not comply with the format specification and
|
|
potentially cause problems, like simpler dequantization, simpler motion
|
|
compensation, assuming use of the default quantization matrix, assuming YUV
|
|
4:2:0 and skipping a few checks to detect damaged bitstreams.
|
|
|
|
``--vd-lavc-o=<key>=<value>[,<key>=<value>[,...]]``
|
|
Pass AVOptions to libavcodec decoder. Note, a patch to make the ``o=``
|
|
unneeded and pass all unknown options through the AVOption system is
|
|
welcome. A full list of AVOptions can be found in the FFmpeg manual.
|
|
|
|
Some options which used to be direct options can be set with this
|
|
mechanism, like ``bug``, ``gray``, ``idct``, ``ec``, ``vismv``,
|
|
``skip_top`` (was ``st``), ``skip_bottom`` (was ``sb``), ``debug``.
|
|
|
|
.. admonition:: Example
|
|
|
|
``--vd--lavc-o=debug=pict``
|
|
|
|
``--vd-lavc-skiploopfilter=<skipvalue> (H.264 only)``
|
|
Skips the loop filter (AKA deblocking) during H.264 decoding. Since
|
|
the filtered frame is supposed to be used as reference for decoding
|
|
dependent frames, this has a worse effect on quality than not doing
|
|
deblocking on e.g. MPEG-2 video. But at least for high bitrate HDTV,
|
|
this provides a big speedup with little visible quality loss.
|
|
|
|
``<skipvalue>`` can be one of the following:
|
|
|
|
:none: Never skip.
|
|
:default: Skip useless processing steps (e.g. 0 size packets in AVI).
|
|
:nonref: Skip frames that are not referenced (i.e. not used for
|
|
decoding other frames, the error cannot "build up").
|
|
:bidir: Skip B-Frames.
|
|
:nonkey: Skip all frames except keyframes.
|
|
:all: Skip all frames.
|
|
|
|
``--vd-lavc-skipidct=<skipvalue> (MPEG-1/2 only)``
|
|
Skips the IDCT step. This degrades quality a lot in almost all cases
|
|
(see skiploopfilter for available skip values).
|
|
|
|
``--vd-lavc-skipframe=<skipvalue>``
|
|
Skips decoding of frames completely. Big speedup, but jerky motion and
|
|
sometimes bad artifacts (see skiploopfilter for available skip values).
|
|
|
|
``--vd-lavc-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).
|
|
|
|
``--version, -V``
|
|
Print version string and exit.
|
|
|
|
``--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.
|
|
|
|
``--vid=<ID|auto|no>``
|
|
Select video channel. ``auto`` selects the default, ``no`` disables 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.
|
|
|
|
``--volstep=<0-100>``
|
|
Set the step size of mixer volume changes in percent of the full range
|
|
(default: 3).
|
|
|
|
``--volume=<-1-100>``
|
|
Set the startup volume. A value of -1 (the default) will not change the
|
|
volume. See also ``--softvol``.
|
|
|
|
``--wid=<ID>``
|
|
(X11 and Windows only)
|
|
This tells mpv to attach to an existing window. The ID is interpreted as
|
|
"Window" on X11, and as HWND on Windows. If a VO is selected that supports
|
|
this option, a new window will be created and the given window will be set
|
|
as parent. The window will always be resized to cover the parent window
|
|
fully, and will add black bars to compensate for the video aspect ratio.
|
|
|
|
See also ``--slave-broken``.
