Yes, v4l2-ctl -L for a list and set it with v4l2-ctl -c <control=value>
   v4l2-ctl -c stream_type=5 (MPEG-2 SVCD-compatible Stream)
   v4l2-ctl -c video_bitrate=<value>

Try to set temporal_filter to 8 or 0 via v4l2-ctl.

Both can not read mpeg streams. Anything that can read mpeg can open 
/dev/videoX directly. I use mplayer mostly for testing.
