--a52drc= Select the Dynamic Range Compression level for AC-3 audio streams. 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= (``--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= 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= 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= Same as ``--af``. --aid= Select audio channel. ``auto`` selects the default, ``no`` disables audio. See also ``--alang``. --alang= 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= 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= 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= Set hinting 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= Set line spacing value for SSA/ASS renderer. --ass-styles= 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= 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= 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= Play audio from an external file (WAV, MP3 or Ogg Vorbis) while viewing a movie. --audiofile-cache= 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= 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= 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= 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= 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= (Blu-ray only) Tells mpv which Blu-ray chapter to start the current title from (default: 1). --bluray-device= (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= 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= 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= Playback will start when the cache has been filled up to of the total (default: 20). --cache-seek-min= If a seek is to be made to a position within 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= This option can be used to tune the CD Audio reading feature of mpv. Available options are: speed= 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= Use specified generic SCSI device. sector-size= Set atomic read size. overlap= Force minimum overlap search during verification to 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= Add sectors to the values reported when addressing tracks. May be negative. (no-)skip (Never) accept imperfect data reconstruction. --cdrom-device= Specify the CD-ROM device (default: ``/dev/cdrom``). --channels= 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= Specify which chapter to start playing at. Optionally specify which chapter to end playing at. Also see ``--start``. --chapter-merge-threshold= 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= 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= 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= 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= 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= (network only) Read HTTP cookies from . 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= 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= 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= Time in milliseconds to recognize two consecutive button presses as a double-click (default: 300). --dvbin= 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=: Instructs mpv to read the channels list from . 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= 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= 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= Some DVD discs contain scenes that can be viewed from multiple angles. Here you can tell mpv which angles to use (default: 1). --edition= (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=
