If you are using the CVS version of mjpegtools there is the "--cbr"
option. Use "--cbr and the "--video-bitrate" together and you can
force a constant bitrate to be generated. Using "--cbr" overrides
the use of the quality (-q) option. Basically with "cbr" the encoder
varies the quality (down/up) to maintain the bitrate, with "vbr"
the quality stays close to constant but the bitrate is varied.
