When blending OSD and subtitles onto the video, we write bogus alpha values. This doesn't normally matter, because these values are normally unused and discarded. But at least on Wayland, the alpha values are used by the compositor and leads to transparent windows even with opaque video on places where the OSD happens to use transparency. (Also see github issue #338.) Until now, the alpha basically contained garbage. The source factor GL_SRC_ALPHA meant that alpha was multiplied with itself. Use GL_ONE instead (which is why we have to use glBlendFuncSeparate()). This should give correct results, even with video that has alpha. (Or at least it's something close to correct, I haven't thought too hard how the compositor will blend it, and in fact I couldn't manage to test it.) If glBlendFuncSeparate() is not available, fall back to glBlendFunc(), which does the same as the code did before this commit. Technically, we support GL 1.1, but glBlendFuncSeparate is 1.4, and I guess we should try not to crash if vo_opengl_old runs on a system with GL 1.1 drivers only. |

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.
mpv's configure script is greedy and automatically enables features as a result
of autodetection. The cases where you may want to use --enable-* are very
limited.
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.
