Statistics for a contributing source (CSRC) that contributed to an inbound RTP stream.

RtcStatsType::Csrc variant.

Fields

contributor_ssrc: Option<u32>

SSRC identifier of the contributing source represented by the stats object, as defined by RFC 3550. It is a 32-bit unsigned integer that appears in the CSRC list of any packets the relevant source contributed to.

inbound_rtp_stream_id: Option<String>

ID of the RTCInboundRtpStreamStats object representing the inbound RTP stream that this contributing source is contributing to.

packets_contributed_to: Option<u64>

Total number of RTP packets that this contributing source contributed to.

This value is incremented each time a packet is counted by RTCInboundRtpStreamStats.packetsReceived, and the packet's CSRC list (as defined by Section 5.1 in RFC 3550) contains the SSRC identifier of this contributing source, contributorSsrc.

audio_level: Option<Float>

Present if the last received RTP packet that this source contributed to contained an RFC 6465 mixer-to-client audio level header extension.

The value of audioLevel is between 0..1 (linear), where 1.0 represents 0 dBov, 0 represents silence, and 0.5 represents approximately 6 dBSPL change in the sound pressure level from 0 dBov. The RFC 6465 header extension contains values in the range 0..127, in units of -dBov, where 127 represents silence. To convert these values to the linear 0..1 range of audioLevel, a value of 127 is converted to 0, and all other values are converted using the equation:

f(rfc6465_level) = 10^(-rfc6465_level/20)
