/* Maintainer notes:
*
* THIS IS A MINIMAL BUILD OF FFMPEG, do not include dependencies unless
* a build that depends on ffmpeg requires them to be compiled into ffmpeg,
* see `ffmpeg-full' for an ffmpeg build with all features included.
*
* Need fixes to support Darwin:
* libvpx pulseaudio
*
* Known issues:
* 0.6 - fails to compile (unresolved) (so far, only disabling a number of
* features works, but that is not a feasible solution)
* 0.6.90 - mmx: compile errors (fix: disable for 0.6.90-rc0)
* 1.1 - libsoxr: compile error (fix: disable for 1.1)
* Support was initially added in 1.1 before soxr api change, fix
* would probably be to add soxr-1.0
* ALL - Cross-compiling will disable features not present on host OS
* (e.g. dxva2 support [DirectX] will not be enabled unless natively
* compiled on Cygwin)
*

FFmpeg is the leading multimedia framework, able to decode, encode, transcode,
mux, demux, stream, filter and play pretty much anything that humans and machines
have created. It supports the most obscure ancient formats up to the cutting edge.
No matter if they were designed by some standards committee, the community or
a corporation.
