I have experienced this situation after flash Flatfish build from 140912 to 140918.

I see bug 1000583 comment 7 have the same situation.


I suspect this is a regression of bug 880780, although I have no evidence.

[Milan Sreckovic [:milan] (needinfo for best results)]

Flatfish specific?

I do not think it is related.

The behavior has changed a bit in latest builds (tested on 2014-12-20) : the screen now remains completely black when using webrtc.
There is also a sound when minimizing the application(or browser tab), like a notification (but there is no text displayed)
Using the camera application, it still works fine. But any application/website using webrtc seems to fail

Attachment: logcat_webrtc.txt

Here is the logcat when trying to use webrtc on appear.in
It displays an error message "Unable to access Camera and microphone".

When using apprtc.appspot.com, it also fails with "getUserMedia() failed. Is this a WebRTC capable browser?" then "Failed to get access to local media. Error name was InternalError. Continuing without sending a stream"
