alvestrand has just created a new issue for https://github.com/w3c/webrtc-stats: == Track stats: track or attachment? == In implementation discussions, it was asked what the stats for a track mean for the case where a track is attached to a PC multiple times. This is not possible using AddTrack, but is possible using ReplaceTrack or AddTransceiver. The WG has previously said that this is "no special treatment" - if you ask for a track to be sent twice, it will be sent twice, and surface at the receiver as two tracks. The cleanest way out seems to be to say that the track stats track the attachment of the track to an RTCPeerConnection, so that the sequence pc.addTrack(a) pc.addTrack(a) pc.getStats(a) will return a stats object with two RTCMediaStreamTrackStats objects in it. For receivers, there is no such discrepancy, because a track is always sourced from a single receiver, and can't be detached from it. @taylor-b @henbos @jan-ivar - comments requested.
