We have no "Last Working" and "First Broken" builds in mozilla-inbound, so I try to find this regressionwindow in b2g-inbound.

Let's see if we can find a smaller window here.

Andreas this seems to have been caused by the changes for bug 1212783. Can you please take a look?

Nominating to 2.6 blocker for broken functionality

There's nothing obvious from bug 1212783 that I see would be wrong. I'm not set up for building or debugging b2g at the moment so I'm trying to get help from Taipei on that part.

In bug 1212783, we added a MediaStreamTrack to DOMCameraControl. With this patch, HTMLMediaElement will remove the playback of CameraPreviewMediaStream after other HTMLMediaElement playback begins. For CameraPreviewMediaStream, we should always keep it alive.

(In reply to Munro Chiang [:munro_chiang] from comment #10) > HTMLMediaElement will remove the playback of CameraPreviewMediaStream > after other HTMLMediaElement playback begins. Hmm, I'd like to know more about this. Generally we can have multiple media elements active at the same time, why not here?

Alastor, this behavior may be related to the audio channel competition mechanism. Could you help check?

Non-audible media element shouldn't involve in audio competing, this issue has been solved in latest m-c.

Can QA verify that this works now? Thanks.
