wm4 8099cbe9dd vo_opengl: add alpha output
Allows playing video with alpha information on X11, as long as the video
contains alpha and the window manager does compositing. See vo.rst.

Whether a window can be transparent is decided by the choice of the X
Visual used for window creation. Unfortunately, there's no direct way to
request such a Visual through the GLX or the X API, and use of the
XRender extension is required to find out whether a Visual implies a
framebuffer with alpha used by XRender (see for example [1]). Instead of
depending on the XRender wrapper library (which would require annoying
configure checks, even though XRender is virtually always supported),
use a simple heuristics to find out whether a Visual has alpha. Since
getting it wrong just means an optional feature will not work as
expected, we consider this ok.

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 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.

Bug reports
===========

Please use the `issues 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.
