       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.
