   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.
