Description Dominique Hazael-Massieux 2013-05-30 21:17:42 UTC 
From what I recall, the constructors for VideoStreamTrack and AudioStreamTrack were defined so that one could build a MediaStream out of them, and then request permission via getUserMedia.

That notion is still vaguely mentioned in the spec:
"Those actions only happen after the developer has requested that a media stream containing "new" tracks be bound to a source via getUserMedia(). Until that point tracks are inert."

But getUserMedia doesn't currently offer a way to get consent for such a manually constructed MediaStream.

We need either to define it, or we should remove the constructors (or at least explain why they can be used for and how).
Comment 1 Stefan Hakansson LK 2013-05-31 07:23:43 UTC 
My view is that we should define how to bind manually created MediaStream to getUserMedia. It is valuable in a WebRTC context.
Comment 2 Harald Alvestrand 2013-08-13 12:41:04 UTC 
My view is that we should remove the constructors until a complete use case and solution (with explanations of how to handle the corner cases) is constructed and proposed.
Comment 3 Stefan Hakansson LK 2014-02-20 13:28:59 UTC 
There has been no activity looking into this. I agree to Harald, let's remove the constructors.
Comment 4 Stefan Hakansson LK 2014-04-01 13:14:04 UTC 
In the latest Editor's draft the constructors are removed.

Closing the bug.
