[FFmpeg-devel] Hap codec

Quick note: there's dxt1 and dxt3 decoding implemented in libavcodec/s3tc.[ch]

Basically, the hap demuxer should output dxt/snappy compressed packets
which are decoded by a hap decoder, which reuses s3tc.c in the
software case and ofloads it to the GPU if that's possible/wanted. Not
sure how other GPU related code is done as I am not following FFmpeg
that closely lately.

I guess libsnappy should indeed be an external dependency like zlib.
