wm4 2e84934be7 input: change license to LGPL 
cehoyos adds the step_property command in 7a71da01d, and it could be
argued that copyright of this still applies to the later add/cycle
commands (a668ae0ff9). While I'm not sure if this is really the case,
stay conservative for now and mark these commands as GPL-only. Mark the
command.c code too, although that is not being relicensed yet.

I'm leaving the MP_CMD_* enum items, as they are obviously different.

In commit 116ca0c768, "veal" (essentially an anonymous author) adds an
"osd_show_property_text" command (well, the commit message says "based
on" that person's code, so it's not clear how much is from him or from
albeu, who agreed to LGPL). This was later merged again with the
"osd_show_text" command, and then all original code was removed in
commit 58cc0f637f, so I claim that no copyright applies anymore. (Though
technically the input.conf addition still might be copyrighted, so I'm
just dropping it to get rid of the thought.)

"kiriuja" added 2f376d1b39 (sub_load etc.) and be54f4813 (switch_audio).
The latter is gone. I would argue that the former is fully rewritten
with commits b7052b431c and 0f155921b0. But like in the step_property
case, I will be overly conservative for now, and mark them as GPL-only,
as this is potentially shaky and should be thought through first. (Not
bothering with the command define/enum in the header, as it will be
unused in LGPL mode anyway.)

keycodes.c/h can be GPL, except for commit 2b1f95dcc2, which is a
patch by someone who wasn't asked yet. Before doing something radical, I
will wait for a reply.

mpv

Overview

mpv is a media player based on MPlayer and mplayer2. It supports a wide variety of video file formats, audio and video codecs, and subtitle types.

Releases can be found on the release list.

System requirements

  • A not too ancient Linux, or Windows Vista or later, or OSX 10.8 or later.
  • A somewhat capable CPU. Hardware decoding might sometimes help if the CPU is too slow to decode video realtime, but must be explicitly enabled with the --hwdec option.
  • A not too crappy GPU. mpv is not intended to be used with bad GPUs. There are many caveats with drivers or system compositors causing tearing, stutter, etc. 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.

Downloads

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

Changelog

There is no completely 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 inidcated in restore-old-bindings.conf.

Compilation

Compiling with full features requires development files for several external libraries. Below is a list of some important requirements.

The mpv build system uses waf but we don't store it in your source tree. The script './bootstrap.py' will download the latest version of waf that was tested with the build system.

For a list of the available build options use ./waf configure --help. If you think you have support for some feature installed but configure fails to detect it, the file build/config.log may contain information about the reasons for the failure.

NOTE: To avoid cluttering the output with unreadable spam, --help only shows one of the two switches for each option. If the option is autodetected by default, the --disable-*** switch is printed; if the option is disabled by default, the --enable-*** switch is printed. Either way, you can use --enable-*** or --disable-** regardless of what is printed by --help.

To build the software you can use ./waf build: the result of the compilation will be located in build/mpv. You can use ./waf install to install mpv to the prefix after it is compiled.

Example:

./bootstrap.py
./waf configure
./waf
./waf install

Essential dependencies (incomplete list):

  • gcc or clang
  • X development headers (xlib, xrandr, xext, xscrnsaver, xinerama, libvdpau, libGL, GLX, EGL, xv, ...)
  • Audio output development headers (libasound/ALSA, pulseaudio)
  • FFmpeg libraries (libavutil libavcodec libavformat libswscale libavfilter and either libswresample or libavresample) At least FFmpeg 3.2.2 or Libav 12 is required. For hardware decoding with vaapi and vdpau, FFmpeg 3.3 or Libav git is required.
  • 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)
  • vdpau and vaapi libraries for hardware decoding on Linux (optional) (FFmpeg 3.3 or Libav git is also required.)

Libass dependencies:

  • gcc or clang, yasm on x86 and x86_64
  • fribidi, freetype, fontconfig development headers (for libass)
  • harfbuzz (optional, 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:

  • gcc or clang, yasm on x86 and x86_64
  • OpenSSL (has to be explicitly enabled when compiling ffmpeg)
  • libx264/libmp3lame/libfdk-aac if you want to use encoding (has to be explicitly enabled when compiling ffmpeg)
  • Libav also works, but some features will not work. (See section below.)

Most of the above libraries are available in suitable versions on normal Linux distributions. However FFmpeg is an exception (distro versions may be too old to work at all or work well). For that reason you may want to use the separately available build wrapper (mpv-build) that 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.

FFmpeg vs. Libav

Generally, mpv should work with the latest release as well as the git version of both FFmpeg and Libav. But FFmpeg is preferred, and some mpv features work with FFmpeg only (subtitle formats in particular).

Preferred FFmpeg version

Using the latest FFmpeg release (or FFmpeg git master) is strongly recommended. Older versions are unsupported, even if the build system still happens to accept them. The main reason mpv still builds with older FFmpeg versions is to evade arguing with people (users, distros) who insist on using older FFmpeg versions for no rational reason.

If you want to use a stable FFmpeg release, use the latest release, which has most likely the best maintenance out of all stable releases. Older releases are for distros, and at best receive basic changes like fixing critical security issues or build fixes, and at worst are completely abandoned.

FFmpeg ABI compatibility

mpv does not support linking against FFmpeg versions it was not built with, even if the linked version is supposedly ABI-compatible with the version it was compiled against. Expect malfunctions, crashes, and security issues if you do it anyway.

The reason for not supporting this is because it creates far too much complexity with little to no benefit, coupled with absurd and unusable FFmpeg API artifacts.

Newer mpv versions will refuse to start if runtime and compile time FFmpeg library versions mismatch.

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.

Contributing

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.

Relation to MPlayer and mplayer2

mpv is based on mplayer2, which in turn is based on the original MPlayer (also called mplayer, mplayer-svn, mplayer1). Many changes have been made, a large part of which is incompatible or completely changes how the player behaves. Although there are still many similarities to its ancestors, mpv should generally be treated as a completely different program.

mpv was forked because we wanted to modernize MPlayer. This includes removing cruft (including features which stopped making sense 10 years ago), and of course adding modern features. Such huge and intrusive changes made it infeasible to work directly with MPlayer, which is mostly focused on preservation, so a fork had to be made. (Actually, mpv is based on mplayer2, which already started this process of removing cruft.)

In general, mpv should be considered a completely new program, rather than a MPlayer drop-in replacement.

If you are wondering what's different from mplayer2 and MPlayer, an incomplete and now unmaintained list of changes is located here.
