NETINT's fork of FFmpeg 7.1 with hardware decoders, encoders and filters
for the NETINT Quadra video processing units, through libxcoder.

The programs are ffmpeg-netint and ffprobe-netint; libraries and headers
live in lib/ffmpeg-netint and include/ffmpeg-netint, so the port does not
conflict with multimedia/ffmpeg. Hardware filters need the decoder option
"-xcoder-params out=hw".
