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).

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

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
