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.
