Using the demo at https://webrtc-demo.vcap.mozillalabs.com/ when in a video call, the video for the Android device is displayed upside down on both the Android and the Desktop display. Tested on a Nexus 4.

I think this is only for the back cam, but with permissions disabled you can't choose any other :P

Sounds like a cut and dry blocker for gUM on Android.

FWIW, for these kind of bugs it's going to be really helpful to check whether the bug exists on multiple devices. Also, the subject implies this is only true in portait mode. Is it?

>Also, the subject implies this is only true in portait mode. Is it? Well darn, it is. That's...not what I would have expected.

The "compensate the mirror" thing came from the Android docs: http://developer.android.com/reference/android/hardware/Camera.html#setDisplayOrientation%28int%29 "So the users can see themselves as looking into a mirror." However, we don't use setDisplayOrientation and show the image that is actually sent to the remote, which doesn't use "mirror" orientation (wtf would you want *that* anyway?). Tested this on a Nexus 4 to give the correct result in all orientations/cameras.
