1475360 - Implement MediaStreamTrack isolated/onisolationchange

Status: NEW

(Core :: WebRTC, enhancement, P3)

Description

[Eric Shepherd [:sheppy]]

The WebRTC spec, section 10.4.1 (https://w3c.github.io/webrtc-pc/#isolated-track), specifies additions to the MediaStreamTrack interface: the isolated attribute and the onisolationchange event handler (for the event isolationchange). isolated is true if the MediaStreamTrack is isolated by either its peerIdentity being set or because the track's contents come from a cross-origin source.

This should be implemented in order to simplify detection of isolation and changes to the isolation state of a track.

Is there a specification compliant procedure to set the peerIdentity?

Comment 2

[Andreas Pehrson [:pehrsons]]

I don't think this will be too hard to implement generically in MediaStreamTrack.

Comment 3

[Andreas Pehrson [:pehrsons]]

With bug 1212237 fixed so that the SecurityError reported there does not happen frequently, I no longer have justification for implementing this. It could still be done, should we want to invest more in shipping all parts of webrtc-identity. I'll upload the patches I have in their current state for the record.
