Certain tools, e.g. compilers, are customarily prefixed with the name of their target platform so that multiple builds can be used at once without clobbering each other on the PATH. I was using identifiers named `prefix` for this purpose, but that conflicts with the standard use of `prefix` to mean the directory where something is installed. To avoid conflict and confusion, I renamed those to `targetPrefix`.

/* 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
