/* 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.
