Minimal publishing bitrate control

It is possible to control minimal published stream bitrate, and stop publuishing if bitrate drops below the threshold during specified time.

This feature is enabled by the following parameter

stream_idle_bitrate_monitoring=true

Bitrate threshold is set in bps with parameter

stream_idle_bitrate_monitoring_threshold_bps=100000

Time interval in which bitrate can be below the threshold is set in seconds with parameter

stream_idle_bitrate_monitoring_window_sec=30

If WebRTC, RTMP, RTSP or VOD stream bitrate is below the threshold during the time specified, publishing is stopped with message in server log

Incoming video rate reached idle threshold, stopping media session, rate 98794

The error message Failed by idle bitrate is returned to publishsing client.

Note that static picture or screen capture stream may be stopped with this setting, in this case bitrate control should be disabled, or bitrate threshold should be set to minimum possible value.
