  -V, --videobitrate     [1 to 16778] encoding bitrate for video (kb/s)
      --optimize         optimize video output filesize (slower)
  -x, --width            scale to given width (in pixels)
  -y, --height           scale to given height (in pixels)
      --aspect           define frame aspect ratio: i.e. 4:3 or 16:9

      --nosound          disable the sound from input

Input options:
      --deinterlace      force deinterlace, otherwise only material
                          marked as interlaced will be deinterlaced
      --vhook            you can use ffmpeg's vhook system, example:

  -f, --format           specify input format
      --inputfps fps     override input fps
      --audiostream id   by default the last audio stream is selected,
                          use this to select another audio stream
      --sync             use A/V sync from input container. Since this does

  -P, --pid fname        write the process' id to a file
  -h, --help             this message

Examples:
  ffmpeg2theora videoclip.avi (will write output to videoclip.ogg)

  cat something.dv | ffmpeg2theora -f dv -o output.ogg -

  Live encoding from a DV camcorder (needs a fast machine):
  dvgrab - | ffmpeg2theora -f dv -x 352 -y 288 -o output.ogg -
