Dudemanguy 4009e99b9c player: remove auto choice from sub-forced-only 
First of all, this never worked. Or if it ever did, it was in some
select few scenarios. c9474dc9ed is what
originally added support for the auto choice. However, that commit
worked by propagating a value to a fake option used internally. This
shouldn't have ever worked because the underlying m_config_cache was
never updated so the value shouldn't have been preserved when accessed
in sd_lavc. And indeed with some testing, the value there is always 0
unsurprisingly.

This was later rewritten in ba7cc07106
along with a lot of other sub changes, but with that, it was still
mostly broken. The reason is because one of the key parts of having to
hit this logic (prefer_forced) required `--no-subs-with-matching-audio`
to be set. If the audio language matches the subtitle language (the
requirement also excludes forced subs), the option makes no subtitle
selection in the first place so pick->forced_only_def is not set to true
and nothing even happens. Another way around this would be to attempt to
change your OS language (like with the LANG environment variable) so
that the subtitle track gets selected but then audio_matches mistakenly
becomes false because it compares the OS language to the audio language
which then make preferred_forced 0, so nothing happens. I don't think
there's a scenario where pick->forced_only_def is actually set to true
(thus meaning `auto` is useless), but maybe someone could contrive
something very strange. Regardless, it's definitely not something even
remotely common.

fbe8f99194 changed track selection again
but didn't consider this particular case. The net result is that DVD/PGS
subs become equivalent to --sub-forced-only being yes, so this a change
in behavior and probably not a good one. Note that I wasn't able to
actually observe any difference in a PGS sample. It still displayed
subtitles fine but that sample probably didn't have the right flags to
hit the sub-forced-only logic.

Anyways, the auto feature is extremely questionable at best and in my
view, not actually worth it. It is meant to be used with
`--no-subs-with-matching-audio` to display forced pictures in subtitle
tracks that are not marked as forced, but that contradicts that
particular option's purpose and description in the manual (secretly
selecting a track under certain conditions even though it says not to).

Instead of trying to shove all this logic into select_default_track
which is already insanely complicated as it is, recognize that this is a
trivial lua script. If you absolutely want to turn --sub-forced-only on
under these certain conditions (DVD/PGS subtitles, matching audio and
subtitle languages, etc.), just look at the current-tracks property and
do your thing. The very, very niche behavior that this option tried to
accomplish basically never worked, no user even knows what this option
does, and well it's just not worth supporting in core mpv code. Drop
all this code for sanity's sake and change --sub-forced-only back to a
bool.

Overview

mpv is a free (as in freedom) media player for the command line. It supports a wide variety of media file formats, audio and video codecs, and subtitle types.

There is a FAQ.

Releases can be found on the release list.

System requirements

  • A not too ancient Linux, Windows 10 or later, or macOS 10.8 or later.
  • A somewhat capable CPU. Hardware decoding might help if the CPU is too slow to decode video in realtime, but must be explicitly enabled with the --hwdec option.
  • A not too crappy GPU. mpv's focus is not on power-efficient playback on embedded or integrated GPUs (for example, hardware decoding is not even enabled by default). Low power GPUs may cause issues like tearing, stutter, etc. The main video output uses shaders for video rendering and scaling, rather than GPU fixed function hardware. On Windows, you might want to make sure the graphics drivers are current. In some cases, ancient fallback video output methods can help (such as --vo=xv on Linux), but this use is not recommended or supported.

mpv does not go out of its way to break on older hardware or old, unsupported operating systems, but development is not done with them in mind. Keeping compatibility with such setups is not guaranteed. If things work, consider it a happy accident.

Downloads

For semi-official builds and third-party packages please see mpv.io/installation.

Changelog

There is no complete changelog; however, changes to the player core interface are listed in the interface changelog.

Changes to the C API are documented in the client API changelog.

The release list has a summary of most of the important changes on every release.

Changes to the default key bindings are indicated in restore-old-bindings.conf.

Compilation

Compiling with full features requires development files for several external libraries. Mpv requires meson to build. Meson can be obtained from your distro or PyPI.

After creating your build directory (e.g. meson setup build), you can view a list of all the build options via meson configure build. You could also just simply look at the meson_options.txt file. Logs are stored in meson-logs within your build directory.

Example:

meson setup build
meson compile -C build
meson install -C build

Essential dependencies (incomplete list):

  • gcc or clang
  • X development headers (xlib, xrandr, xext, xscrnsaver, xpresent, libvdpau, libGL, GLX, EGL, xv, ...)
  • Audio output development headers (libasound/ALSA, pulseaudio)
  • FFmpeg libraries (libavutil libavcodec libavformat libswscale libavfilter and either libswresample or libavresample)
  • zlib
  • iconv (normally provided by the system libc)
  • libass (OSD, OSC, text subtitles)
  • Lua (optional, required for the OSC pseudo-GUI and youtube-dl integration)
  • libjpeg (optional, used for screenshots only)
  • uchardet (optional, for subtitle charset detection)
  • nvdec and vaapi libraries for hardware decoding on Linux (optional)

Libass dependencies (when building libass):

  • gcc or clang, yasm on x86 and x86_64
  • fribidi, freetype, fontconfig development headers (for libass)
  • harfbuzz (required for correct rendering of combining characters, particularly for correct rendering of non-English text on OSX, and Arabic/Indic scripts on any platform)

FFmpeg dependencies (when building FFmpeg):

  • gcc or clang, yasm on x86 and x86_64
  • OpenSSL or GnuTLS (have to be explicitly enabled when compiling FFmpeg)
  • libx264/libmp3lame/libfdk-aac if you want to use encoding (have to be explicitly enabled when compiling FFmpeg)
  • For native DASH playback, FFmpeg needs to be built with --enable-libxml2 (although there are security implications, and DASH support has lots of bugs).
  • AV1 decoding support requires dav1d.
  • For good nvidia support on Linux, make sure nv-codec-headers is installed and can be found by configure.

Most of the above libraries are available in suitable versions on normal Linux distributions. For ease of compiling the latest git master of everything, you may wish to use the separately available build wrapper (mpv-build) which first compiles FFmpeg libraries and libass, and then compiles the player statically linked against those.

If you want to build a Windows binary, you either have to use MSYS2 and MinGW, or cross-compile from Linux with MinGW. See Windows compilation.

Release cycle

Every other month, an arbitrary git snapshot is made, and is assigned a 0.X.0 version number. No further maintenance is done.

The goal of releases is to make Linux distributions happy. Linux distributions are also expected to apply their own patches in case of bugs and security issues.

Releases other than the latest release are unsupported and unmaintained.

See the release policy document for more information.

Bug reports

Please use the issue tracker provided by GitHub to send us bug reports or feature requests. Follow the template's instructions or the issue will likely be ignored or closed as invalid.

Using the bug tracker as place for simple questions is fine but IRC is recommended (see Contact below).

Contributing

Please read contribute.md.

For small changes you can just send us pull requests through GitHub. For bigger changes come and talk to us on IRC before you start working on them. It will make code review easier for both parties later on.

You can check the wiki or the issue tracker for ideas on what you could contribute with.

License

GPLv2 "or later" by default, LGPLv2.1 "or later" with -Dgpl=false. See details.

History

This software is based on the MPlayer project. Before mpv existed as a project, the code base was briefly developed under the mplayer2 project. For details, see the FAQ.
