henbos has just created a new issue for https://github.com/w3c/webrtc-pc: == replaceTrack and removeTrack == Paraphrasing the spec ignoring some details... replaceTrack is asynchronous: - In parallel, check that track has not ended and queue a task to set the track if the pc is not closed and resolve the promise. The track could be muted before the queued task is executed, this could be a problem, but ignoring that for now. removeTrack is synchronous: - Set the sender's track to null, etc. What is the expected behavior of this? ``` sender = pc.addTrack(t1); sender.replaceTrack(t2); pc.removeTrack(sender); ``` I imagine this will result in the following steps: ``` sender = sender with track = t1; // pc.addTrack sender.track = null; // pc.removeTrack sender.track = t2; // replaceTrack ``` The removeTrack still changes the direction of the transceiver, so I suspect the renegotiation will cause the remote track to be removed regardless of the order of things, but there might be races with what sender.track is when renegotiating?
