How to delete track from MediaStream webcam and "stop"?

I am trying to remove a track from MediaStream. MediaStream.removeTrack() removes the track from the stream, but the camera light remains on the display, indicating that the camera is still active.

https://developer.mozilla.org/en-US/docs/Web/API/MediaStreamTrack?redirectlocale=en-US&redirectslug=DOM%2FMediaStreamTrack

This refers to the stop() method, which I suppose will completely stop the camera. In chrome, however, I get "Object MediaStreamTrack has no method 'stop'"

Is there a way around this, or do I need to stop the entire stream and then recreate it using tracks that I don't want to leave? For example, I want to delete a video track while the audio track is still there.

MediaStreamTrack.stop() now added in Chrome.

MediaStream.stop() deprecated in Chrome 45.

You must use MediaStream.getVideoTracks() to get the video tracks and stop the track using MediaStreamTrack.stop()

You need to call stop () in MediaStream, not MediaStreamTrack.

Take a look at simpl.info/gum . On the console, call stream.stop() : recording stops, and the camcorder's indicator goes off.

It seems that the right way to deal with this problem is to stop your MediaStream , recreate (and reconnect) it as audio only, and then renegotiate the PeerConnection session. Unfortunately, Firefox does not currently support a revised average session.

Thus, the only viable hack is also to recreate PeerConnection with the new MediaStream , as suggested here (see "Adding a video in the middle of -Call").
