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

See man ffmpeg for detailed description of the options.
