937110 - When one of several video elements using the same LocalMediaStream source is deleted, the remaining video elements freeze

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, defect)

Description

[Thomas Bruun]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.101 Safari/537.36

Steps to reproduce:

1. Retrieve stream using getUserMedia
2. Create two <video> elements using the same stream
3. Remove one of the two elements from the DOM

Example: http://jsfiddle.net/Uxw2j/


Actual results:

The second video element freezes, displaying a frame from the stream before the first video element was removed.


Expected results:

The second video element should continue playing the stream. 

This also affects the stream being sent to other peers using RTCPeerConnection. User twi at #media was able to create a workaround by setting the src attribute of the video to be removed to something different, before removing the element.
