#ffmpeg

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/protocol

See man ffmpeg for detailed description of the options.
