       Universal media converter 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.

       Per-stream  options  can  be  followed  by  :<stream_spec> to apply that option to specific streams only.
       <stream_spec> can be a stream index, or v/a/s for video/audio/subtitle (see manual for full syntax).

       specified time is reached -ss <time_off>      start transcoding at specified time

       Per-file options (output-only): -metadata[:<spec>] <key=value>  add metadata

       Per-stream  options:  -c[:<stream_spec>]  <codec>   select encoder/decoder ('copy' to copy stream without
       reencoding) -filter[:<stream_spec>] <filter_graph>  apply specified filters to audio/video

       Video options: -r[:<stream_spec>] <rate>  override input framerate/convert to given output framerate  (Hz
       value, fraction or abbreviation) -aspect[:<stream_spec>] <aspect>  set aspect ratio (4:3, 16:9 or 1.3333,
       1.7777)  -vn                 disable video -vcodec <codec>     alias for -c:v (select encoder/decoder for
       video streams) -vf <filter_graph>  alias for -filter:v (apply filters  to  video  streams)  -b  <bitrate>
       video bitrate (please use -b:v)

       Audio  options:  -aq  <quality>        set audio quality (codec-specific) -ar[:<stream_spec>] <rate>  set
       audio  sampling  rate  (in  Hz)  -ac[:<stream_spec>]  <channels>   set  number  of  audio  channels   -an
       disable audio -acodec <codec>     alias for -c:a (select encoder/decoder for audio streams) -ab <bitrate>
       alias  for -b:a (select bitrate for audio streams) -af <filter_graph>  alias for -filter:a (apply filters
       to audio streams)

       Subtitle options: -sn                  disable  subtitle  -scodec  <codec>      alias  for  -c:s  (select
