RTCOutboundRtpStreamStats: targetBitrate property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The targetBitrate property of the RTCOutboundRtpStreamStats dictionary represents the current target bitrate of the codec in use by the stream.

The value is dynamic, reflecting the encoder settings and other factors such as network conditions and available bandwidth. It should correlate closely to the payload bytes sent per second (excluding retransmissions).

Value

A number representing the target rate in bits per second. This is defined in the same way as the RFC 3890: Transport Independent Application Specific (TIAS) bitrate.
