FFmpeg Package

Hyper fast Audio and Video encoder
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

Getting help:

-h-- print basic options -h long-- print more options -h full-- print all options (including all format and codec specific options, very long) -h type=name-- print all options for the named decoder/encoder/demuxer/muxer/filter/bsf See man ffmpeg for detailed description of the options.
