mpeg1video encoder AVOptions:
  -gop_timecode      <string>     E..V.. MPEG GOP Timecode in hh:mm:ss[:;.]ff format
  -intra_vlc         <int>        E..V.. Use MPEG-2 intra VLC table. (from 0 to 1)
  -drop_frame_timecode <int>        E..V.. Timecode is in drop frame format. (from 0 to 1)
  -scan_offset       <int>        E..V.. Reserve space for SVCD scan offset user data. (from 0 to 1)
  -mpv_flags         <flags>      E..V.. Flags common for all mpegvideo-based encoders.
     skip_rd                      E..V.. RD optimal MB level residual skipping
     strict_gop                   E..V.. Strictly enforce gop size
     qp_rd                        E..V.. Use rate distortion optimization for qp selection
     cbp_rd                       E..V.. use rate distortion optimization for CBP
  -luma_elim_threshold <int>        E..V.. single coefficient elimination threshold for luminance (negative values also consider dc coefficient) (from INT_MIN to INT_MAX)
  -chroma_elim_threshold <int>        E..V.. single coefficient elimination threshold for chrominance (negative values also consider dc coefficient) (from INT_MIN to INT_MAX)
