wm4 a1a9dc9c85 options: remove --no-vsync 
Latest nvidia drivers ignore the application setting, so this switch
makes even less sense than before. It's still possible to control this
with VO specific suboptions.

Raw Blame History

--a52drc=<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.
--abs=<value>
(``--ao=oss`` only) (OBSOLETE)
Override audio driver/card buffer size detection.
--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 to other available
decoders not on the ``--ad`` list. ``+`` in front of an entry forces the
decoder. Both of these shouldn't normally be used, because they break
normal decoder auto-selection!
``-`` in front of an entry disables selection of the decoder.
*EXAMPLE*:
``--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.
--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
shouldn't need these for typical use.
--af-adv=<force=(0-7):list=(filters)>
See also ``--af``.
Specify advanced audio filter options:
force=<0-7>
Forces the insertion of audio filters to one of the following:
0
Use completely automatic filter insertion (currently identical to
1).
1
Optimize for accuracy (default).
2
Optimize for speed. *Warning*: Some features in the audio filters
may silently fail, and the sound quality may drop.
3
Use no automatic insertion of filters and no optimization.
*Warning*: It may be possible to crash mpv using this setting.
4
Use automatic insertion of filters according to 0 above, but use
floating point processing when possible.
5
Use automatic insertion of filters according to 1 above, but use
floating point processing when possible.
6
Use automatic insertion of filters according to 2 above, but use
floating point processing when possible.
7
Use no automatic insertion of filters according to 3 above, and
use floating point processing when possible.
list=<filters>
Same as ``--af``.
--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``.
*EXAMPLE*:
``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 you'd normally specify a single one to use, but in
configuration files specifying a list of fallbacks may make sense. See
`audio_outputs` 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``.
*EXAMPLE*:
- ``--aspect=4:3`` or ``--aspect=1.3333``
- ``--aspect=16:9`` or ``--aspect=1.7777``
--ass, --no-ass
Render ASS subtitles natively, and convert text subtitles in other formats
to ASS internally (enabled by default).
If ``--no-ass`` is specified, all subtitles are converted to plain text
internally. All tags and style declarations are stripped and ignored. 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.
*EXAMPLE*:
- ``--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 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>
Force 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-demuxer=audio`` forces MP3.
--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 streams.
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 don't 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.
*EXAMPLE*:
``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.
*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.
Here you can tell mpv which angles to use (default: 1).
--bluray-chapter=<ID>
(Blu-ray only)
Tells mpv which Blu-ray chapter to start the current title from
(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>
Enable caching of the input stream (if not already enabled) and set the
size of the cache in kilobytes. Caching is enabled by default (with a
default cache size) for network streams. 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. See also ``--no-cache``.
--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).
--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 Toshiba drives need this for getting
track boundaries correct.
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>
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 audio (like DVDs). In that case
liba52 does the decoding by default and correctly downmixes the audio into
the requested number of channels. To directly control the number of output
channels independently of how many channels are decoded, use the channels
filter (``--af=channels``).
*NOTE*: This option is honored by codecs (AC-3 only), filters (surround)
and audio output drivers (OSS at least).
Available options are:
:2: stereo
:4: surround
:6: full 5.1
:8: full 7.1
--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 don't follow standard color
levels or which are flagged wrong. If the video doesn't 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 level RGB. 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
--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. Supported by video output drivers which use X11 or
OS X Cocoa.
--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``.
--doubleclick-time=<milliseconds>
Time in milliseconds to recognize two consecutive button presses as a
double-click (default: 300).
--dtshd, --no-dtshd
When using DTS passthrough, output any DTS-HD track as-is.
With ``--no-dtshd`` (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.
--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 a 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 DVD discs contain scenes that can be viewed from multiple angles.
Here you can tell mpv which angles 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.
--no-extbased, --extbased
``--no-extbased`` disables extension-based demuxer selection. By default, when the file type
(demuxer) cannot be detected reliably (the file has no header or it is not
reliable enough), the filename extension is used to select the demuxer.
Always falls back on content-based demuxer selection.
--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 to ``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> frames, then quit.
--fullscreen, --fs
Fullscreen playback (centers movie, and paints black bands around it).
--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 to using the behaviour
depending on what the user provided with the ``screen`` option.
*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.
*NOTE (OSX)*: ``all`` doesn't 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.
*EXAMPLE*:
``--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.
--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's 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 samplerate then the
following files may get resampled to the same low samplerate, 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 of the screen to the top-left 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.
*NOTE (OSX)*: On Mac OSX the origin of the screen coordinate system is
located on the the bottom-left corner. For instance, ``0:0`` will place the
window at the bottom-left of the screen.
*NOTE (X11)*: this option does not work properly with all window managers.
*EXAMPLE*:
``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.
*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-xscreensaver``). If you think this is too
complicated, ask the author of the screensaver program to support the
proper X APIs.
*EXAMPLE for xscreensaver*: ``mpv --heartbeat-cmd="xscreensaver-command
-deactivate" file``
*EXAMPLE for GNOME screensaver*: ``mpv
--heartbeat-cmd="gnome-screensaver-command -p" file``
--help
Show short summary of options.
--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's possible to explicitly override that
default in the definition of key bindings and in slave mode commands.
:no: Never use precise seeks.
:absolute: Use precise seeks if the seek is to an absolute position in the
file, such as a chapter seek, but not for relative seeks like
the default behavior of arrow keys (default).
:yes: Use precise seeks whenever possible.
--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.
*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 to 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
--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``).
--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).
--ignore-start
Matters with the builtin AVI demuxer only, which is not enabled by default.
Ignore the specified starting time for streams in AVI files. This
nullifies stream delays.
--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-dev=<device>
Device to be used for Apple IR Remote (default is autodetected, Linux
only).
--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
Use the key bindings that mpv ships with by default.
--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``.
*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).
--ipv4-only-proxy
Skip any HTTP proxy for IPv6 addresses. It will still be used for IPv4
connections.
*WARNING*: works with the deprecated ``mp_http://`` protocol only.
--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.
--lavdopts=<option1:option2:...>
Specify libavcodec decoding parameters. Separate multiple options with a
colon.
*EXAMPLE*: ``--lavdopts=gray:skiploopfilter=all:skipframe=nonref``
Available options are:
bitexact
Only use bit-exact algorithms in all decoding steps (for codec
testing).
bug=<value>
Manually work around encoder bugs.
:0: nothing
:1: autodetect bugs (default)
:2: (msmpeg4v3): some old lavc generated msmpeg4v3 files (no
autodetection)
:4: (mpeg4): Xvid interlacing bug (autodetected if fourcc==XVIX)
:8: (mpeg4): UMP4 (autodetected if fourcc==UMP4)
:16: (mpeg4): padding bug (autodetected)
:32: (mpeg4): illegal vlc bug (autodetected per fourcc)
:64: (mpeg4): Xvid and DivX qpel bug (autodetected per
fourcc/version)
:128: (mpeg4): old standard qpel (autodetected per fourcc/version)
:256: (mpeg4): another qpel bug (autodetected per fourcc/version)
:512: (mpeg4): direct-qpel-blocksize bug (autodetected per
fourcc/version)
:1024: (mpeg4): edge padding bug (autodetected per fourcc/version)
debug=<value>
Display debugging information.
:0: disabled
:1: picture info
:2: rate control
:4: bitstream
:8: macroblock (MB) type
:16: per-block quantization parameter (QP)
:32: motion vector
:0x0040: motion vector visualization
:0x0080: macroblock (MB) skip
:0x0100: startcode
:0x0200: PTS
:0x0400: error resilience
:0x0800: memory management control operations (H.264)
:0x1000: bugs
:0x2000: Visualize quantization parameter (QP), lower QP are tinted
greener.
:0x4000: Visualize block types.
ec=<value>
Set error concealment strategy.
:1: Use strong deblock filter for damaged MBs.
:2: iterative motion vector (MV) search (slow)
:3: all (default)
fast (MPEG-2, MPEG-4, and H.264 only)
Enable optimizations which do not comply to the specification and
might 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.
gray
grayscale only decoding (a bit faster than with color)
idct=<0-99>
For best decoding quality use the same IDCT algorithm for decoding and
encoding. This may come at a price in accuracy, though.
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.
*EXAMPLE*: ``o=debug=pict``
sb=<number> (MPEG-2 only)
Skip the given number of macroblock rows at the bottom.
st=<number> (MPEG-2 only)
Skip the given number of macroblock rows at the top.
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 no 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.
skipidct=<skipvalue> (MPEG-1/2 only)
Skips the IDCT step. This degrades quality a lot of in almost all
cases (see skiploopfilter for available skip values).
skipframe=<skipvalue>
Skips decoding of frames completely. Big speedup, but jerky motion and
sometimes bad artifacts (see skiploopfilter for available skip
values).
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)
vismv=<value>
Visualize motion vectors.
:0: disabled
:1: Visualize forward predicted MVs of P-frames.
:2: Visualize forward predicted MVs of B-frames.
:4: Visualize backward predicted MVs of B-frames.
--lavfdopts=<option1:option2:...>
Specify parameters for libavformat demuxers (``--demuxer=lavf``). Separate
multiple options with a colon.
Available suboptions are:
analyzeduration=<value>
Maximum length in seconds to analyze the stream properties.
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.)
format=<value>
Force a specific libavformat demuxer.
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.
*EXAMPLE*: ``o=fflags=+ignidx``
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.
cryptokey=<hexstring>
Encryption key the demuxer should use. This is the raw binary data of
the key converted to a hexadecimal string.
--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 whole playlist
is looped.
--mc=<seconds/frame>
Maximum A-V sync correction per frame (in seconds)
--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.
alsamixer 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``.
*EXAMPLE*:
- ``--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
Enabled by default. Disable mouse button press/release input
(mozplayerxp's context menu relies on this option).
--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 its
description below 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.
--avi-ni
(Internal AVI demuxer which is not used by default only)
Force usage of non-interleaved AVI parser (fixes playback of some bad AVI
files).
--no-aspect
Ignore aspect ratio information from video file and assume the video has
square pixels. See also ``--aspect``.
--no-bps
(Internal AVI demuxer which is not used by default only)
Do not use average byte/second value for A-V sync. Helps with some AVI
files with broken header.
--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 cddb, 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-sub
Disables display of internal and external subtitles.
--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-back-color=<#RRGGBB>, --sub-text-back-color=<#RRGGBB>
See ``--osd-color``. Color used for OSD/sub text background.
--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).
*EXAMPLE*:
- ``--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``.
*EXAMPLE*:
- ``--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-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 ``--playing-msg``.
--overlapsub
Allows the next subtitle to be displayed while the current one is still
visible (default is to enable the support only for specific formats). This
only matters for subtitles loaded with ``-sub``.
--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``.
--passwd=<password>
Used with some network protocols. Specify password for HTTP authentication.
See also ``--user``.
*WARNING*: works with the deprecated ``mp_http://`` protocol only.
--playing-msg=<string>
Print out a string before starting playback. The string is expanded for
properties, e.g. ``--playing-msg=file: ${filename}`` will print the string
``file:`` followed by a space and the currently played filename.
The following expansions are supported:
\${NAME}
Expands to the value of the property ``NAME``. If ``NAME`` starts with
``=``, use the raw value of the property. If retrieving the property
fails, expand to an error string. (Use ``${NAME:}`` with a trailing
``:`` to expand to an empty string instead.)
\${NAME:STR}
Expands to the value of the property ``NAME``, or ``STR`` if the
property can't be retrieved. ``STR`` is expanded recursively.
\${!NAME:STR}
Expands to ``STR`` (recursively) if the property ``NAME`` can't be
retrieved.
\${?NAME:STR}
Expands to ``STR`` (recursively) if the property ``NAME`` is available.
\$\$
Expands to ``$``.
\$}
Expands to ``}``. (To produce this character inside recursive
expansion.)
\$>
Disable property expansion and special handling of ``$`` for the rest
of the string.
This option also parses C-style escapes. Example:
- ``\n`` becomes a newline character
- ``\\`` expands to ``\``
--status-msg=<string>
Print out a custom string during playback instead of the standard status
line. Expands properties. See ``--playing-msg``.
--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 don't trust!
FIXME: This needs to be clarified and documented thoroughly.
--pp=<quality>
See also ``--vf=pp``.
--pphelp
See also ``--vf=pp``.
--prefer-ipv4
Use IPv4 on network connections. Falls back on IPv6 automatically.
*WARNING*: works with the deprecated ``mp_http://`` protocol only.
--prefer-ipv6
Use IPv6 on network connections. Falls back on IPv4 automatically.
*WARNING*: works with the deprecated ``mp_http://`` protocol only.
--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 shouldn't 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. 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``.
--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.
*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.
--rawaudio=<option1:option2:...>
This option lets you play raw audio files. You have to use
``--demuxer=rawaudio`` as well. It may also be used to play audio CDs
which are not 44kHz 16-bit stereo.
Available options are:
:channels=<value>: number of channels
:rate=<value>: rate in samples per second
:format=<value>: mpv audio format (e.g. s16le)
--rawvideo=<option1:option2:...>
This option lets you play raw video files. You have to use
``--demuxer=rawvideo`` as well.
Available options are:
:fps=<value>: rate in frames per second (default: 25.0)
:w=<value>: image width in pixels
:h=<value>: image height in pixels
:format=<value>: colorspace (fourcc) in hex or string
constant.
:mp-format=<value>: colorspace by internal video format
Use ``--rawvideo=mp-format=help``
for a list of possible formats.
:codec: set the video codec (instead of selecting
the rawvideo codec)
:size=<value>: frame size in Bytes
*EXAMPLE*:
- ``mpv foreman.qcif --demuxer=rawvideo --rawvideo=qcif`` Play the
famous "foreman" sample video.
- ``mpv sample-720x576.yuv --demuxer=rawvideo --rawvideo=w=720:h=576``
Play a raw YUV sample.
--really-quiet
Display even less output and status messages than with ``--quiet``.
--referrer=<string>
Specify a referrer path or URL for HTTP requests.
--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.
--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 doesn't always work. In these cases, try to use ``--geometry``
to position the window explicitly.
*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-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 won't 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 won't 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 that 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 doesn't 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``.
*EXAMPLE*:
- ``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.
*NOTE*: 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, if there is enough interest).
This affects smplayer, smplayer2, mplayerosx, and others.
--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 resample or lavcresample audio filter will be
inserted into the audio filter layer to compensate for the difference. The
type of resampling can be controlled by the ``--af-adv`` option.
--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.)
*EXAMPLE*:
``--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
*EXAMPLE*: ``--vf=scale --ssf=lgb=3.0``
--sstep=<sec>
Skip <sec> seconds after every frame.
*NOTE*: without ``--hr-seek``, skipping will snap to keyframes.
--stereo=<mode>
Select type of MP2/MP3 stereo output.
:0: stereo
:1: left channel
:2: right channel
--stop-xscreensaver
(X11 only)
Turns off xscreensaver at startup and turns it on again on exit. If your
screensaver supports neither the XSS nor XResetScreenSaver API please use
``--heartbeat-cmd`` instead.
--sub=<subtitlefile1,subtitlefile2,...>
Use/display these subtitle files. Only one file can be displayed at the
same time.
--sub-demuxer=<[+]name>
Force subtitle demuxer type for ``--subfile``. Using a '+' before the name
will force it, this will skip some checks! Give the demuxer name as
printed by ``--sub-demuxer=help``.
--sub-no-text-pp
Disables any kind of text post processing done after loading the
subtitles. Used for debug purposes.
--sub-paths=<path1:path2:...>
Specify extra directories where 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.
*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.
*EXAMPLE*:
- ``--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 and
watch mpv ``-v`` output for available languages. Fallback codepage
specifies the codepage to use, when autodetection fails.
*EXAMPLE*:
- ``--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.
--sub-delay=<sec>
Delays subtitles by <sec> seconds. Can be negative.
--subfile=<filename>
Open the given file with a demuxer, and use its subtitle streams. Same as
``--audiofile``, but for subtitle streams.
*NOTE*: use ``--sub`` for subtitle files. This option is useless, unless
you want to force libavformat subtitle parsers instead of libass or
internal subtitle parsers.
--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.
--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 affects 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.
--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 ``--playing-msg``).
--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.
*EXAMPLE*: ``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]=<0-65535> (v4l1)
[volume|bass|treble|balance]=<0-100> (v4l2)
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> (v4l2)
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).
hidden_video_renderer (dshow only)
Terminate stream with video renderer instead of Null renderer
(default: off). Will help if video freezes but audio does not.
*NOTE*: May not work with ``--vo=directx`` and ``--vf=crop``
combination.
hidden_vp_renderer (dshow only)
Terminate VideoPort pin stream with video renderer instead of removing
it from the graph (default: off). Useful if your card has a VideoPort
pin and video is choppy.
*NOTE*: May not work with ``--vo=directx`` and ``--vf=crop``
combination.
system_clock (dshow only)
Use the system clock as sync source instead of the default graph clock
(usually the clock from one of the live sources in graph).
normalize_audio_chunks (dshow only)
Create audio chunks with a time length equal to video frame time
length (default: off). Some audio cards create audio chunks about 0.5s
in size, resulting in choppy video when using immediatemode=0.
--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.
*WARNING*: May be dangerous if playing from untrusted media.
--user=<username>
Used with some network protocols.
Specify username for HTTP authentication. See also ``--passwd``.
*WARNING*: works with the deprecated ``mp_http://`` protocol only.
--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.
--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
shouldn't 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 you'd normally specify a single one to use, but in
configuration files specifying a list of fallbacks may make sense. See
`video_outputs` for details and descriptions of available drivers.
--volstep=<0-100>
Set the step size of mixer volume changes in percent of the whole 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 win32 only)
This tells mpv to attach to an existing window. The ID is interpreted as
"Window" on X11, and as HWND on win32. 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 ``--slave-broken``.
