Remove the special casing of vo_vdpau vs. other VOs. Replace the complicated interaction between vo.c and vo_vdpau.c with a simple queue in vo.c. VOs other than vdpau are handled by setting the length of the queue to 1 (this is essentially what waiting_mpi was). Note that vo_vdpau.c seems to have buffered only 1 or 2 frames into the future, while the remaining 3 or 4 frames were past frames. So the new code buffers 2 frames (vo_vdpau.c requests this queue length by setting vo->max_video_queue to 2). It should probably be investigated why vo_vdpau.c kept so many past frames. The field vo->redrawing is removed. I'm not really sure what that would be needed for; it seems pointless. Future directions include making the interface between playloop and VO simpler, as well as making rendering a frame a single operation, as opposed to the weird 3-step sequence of rendering, drawing OSD, and flipping.
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, pulseaudio)
- FFmpeg libraries (libavutil libavcodec libavformat libswscale libavresample) At least FFmpeg 2.1.4 or Libav 10 is required.
- libjpeg (for screenshots)
- libquvi if you want to play Youtube videos directly
Libass dependencies:
- gcc or clang, yasm on x86 and x86_64
- fribidi, freetype, fontconfig development headers (for libass)
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.
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.

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.
Contacts
These forms of contact are meant to ask questions about mpv usage, give feedback on mpv and discuss it's development.
If possible, please avoid posting bugs here and use the issue tracker instead.
