It appears the API requires you to cover all plane data with AVBuffers (that is, one AVBuffer per plane in the most general case), because certain code can make certain assumptions about this. (Insert rant about how this is barely useful and increases complexity and potential bugs.) I don't know any cases where the current code actually fails, but we want to follow the API, so do it anyway. Note that we don't really know whether or not planes are from a single memory allocation, so we have to assume the most general case and create an AVBuffer for each plane. We simply assume that the data is padded to the full stride in the last image line. All these extra dummy references are stupid, but the code might become much simpler once we only support libavcodec versions with refcounting and can use AVFrame directly. |

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. For
more information see the output of ./configure --help
for a list of options,
or look at the list of enabled and disabled features printed after running
./configure
. If you think you have support for some feature installed
but configure fails to detect it, the file config.log
may contain
information about the reasons for the failure.
Essential dependencies (incomplete list):
- gcc or clang
- X development headers (xlib, X extensions, libvdpau, libGL, libXv, ...)
- Audio output development headers (libasound, pulseaudio)
- fribidi, freetype, fontconfig development headers (for libass)
- libass
- FFmpeg libraries (libavutil libavcodec libavformat libswscale libpostproc)
- libjpeg
- libquvi if you want to play Youtube videos directly
- libx264/libmp3lame/libfdk-aac if you want to use encoding (has to be explicitly enabled when compiling ffmpeg)
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.
configure --enable-* parameters
The --enable-* parameters unconditionally force options on, completely skipping autodetection. This behavior is unlike what you may be used to from autoconf-based configure scripts that can decide to override you. This greater level of control comes at a price. You may have to provide the correct compiler and linker flags yourself. If you used one of these options and experience a compilation or linking failure, make sure you have passed the necessary compiler/linker flags to configure.

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.
