James Ross-Gowan 3c10ed540b ao_wasapi: fix try_format logic in shared mode 
The MSDN documentation for IsFormatSupported says a return code of
AUDCLNT_E_UNSUPPORTED_FORMAT means the function "succeeded but the
specified format is not supported in exclusive mode." This seems to
imply that the format is supported in shared mode, and that's what the
old code assumed, however try_format would incorrectly return success
with some drivers.

The remarks section of the documentation contradicts that assumption. It
says that in shared mode, if the audio engine does not support the
caller-specified format or any similar format, ppClosestMatch is set to
NULL and the function returns AUDCLNT_E_UNSUPPORTED_FORMAT. This is the
same as in exclusive mode, so treat AUDCLNT_E_UNSUPPORTED_FORMAT the
same regardless of opt_exclusive. In shared mode, the format selection
code will fall back to the mix format, which should always be supported.

mpv

Overview

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

If you are wondering what's different from mplayer2 and MPlayer you can read more about the changes.

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.

NOTE: Using the old build system (with ./old-configure) should still work, but will be removed in a future version of mpv.

Essential dependencies (incomplete list):

  • gcc or clang
  • X development headers (xlib, X extensions, libvdpau, libGL, libXv, ...)
  • Audio output development headers (libasound/ALSA, pulseaudio)
  • FFmpeg libraries (libavutil libavcodec libavformat libswscale libavfilter and either libswresample or libavresample) At least FFmpeg 2.1.4 or Libav 10 is required.
  • libass
  • Lua (optional, required for the OSC pseudo-GUI)
  • libjpeg (optional, used for screenshots only)
  • Enca (optional, for subtitle charset detection)
  • vdpau and vaapi libraries for hardware decoding on Linux (optional)

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 are running Mac OSX and using homebrew we provide homebrew-mpv, an up to date formula that compiles mpv with sensible dependencies and defaults for OSX.

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. See the wiki article about the issue.

Release cycle

Every few months, a new release is cut off of the master branch and is assigned a 0.X.0 version number.

As part of the maintenance process, minor releases are made, which are assigned 0.X.Y version numbers. Minor releases contain bug fixes only. They never merge the master branch, and no features are added to it. Only the latest release is maintained.

The goal of releases is to provide stability and an unchanged base for the sake of Linux distributions. If you want the newest features, just use the master branch, which is stable most of the time, except sometimes, when it's not.

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.
