Status: RESOLVED INCOMPLETE

(Core :: WebRTC, enhancement)

Description

[Justin Uberti]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.89 Safari/537.36

Steps to reproduce:

Run https://webrtc.github.io/samples/src/content/peerconnection/pc1/ in Firefox.

Then do pc2.getStats().then(stats => stats.forEach(item => console.log(item))) in the JS console.

Actual results:

Observe output similar to { id: "5b6ba3c7", timestamp: 1595529829865, type: "inbound-rtp", kind: "video", mediaType: "video", ssrc: 1924989198, discardedPackets: 0, jitter: 0.003, packetsLost: 0, packetsReceived: 7988, … }.

Note the absence of many fields from https://www.w3.org/TR/webrtc-stats/#dom-rtcinboundrtpstreamstats, including |framesReceived|, |framesDecoded|, |totalSamplesReceived|, |concealedSamples|, |trackId|, and others. These fields are important for analyzing received media quality.

Expected results:

The aforementioned fields should have appeared in the inbound-rtp stats object.

looks ok-ish, lets close this (somehow I stumbled over this)?

Most of these are already fixed, see here
