(positive integer value)
max allowed guest bitrate
Useful if you are a director and you wish to prevent guests from pulling more than 500-kbps (LQ) or 1200-kbps (HQ) when in broadcast mode.
Set to 600-kbps, 200-kbps, or 80-kbps if the goal is to reduce CPU load also. (2x, 3x, or 4x down-scaling is applied at those bitrate limits).
