Trying to establish a call from an Android device to a Windows machine fails to render the remote video streams
Build: Firefox Nightly 24 Desktop OS: Windows 7 64-bit Android Device: Samsung Galaxy Nexus Android OS: Android 4.2 STR 1. Go to apprtc.appspot.com on FxAndroid 2. Go to the URL derived from #1 on apprtc on a desktop machine 3. Accept permissions on your desktop machine Expected The remote camera stream should render - desktop should see the Android video, android should see the desktop video. Actual The remote camera stream fails to render. Additional Notes: Interestingly enough, I did confirm the call was established - I was able to send and receive audio across my Android and desktop device. So something isn't working correctly with the video streams then.
Same problem as on the mobile demo pages (https://webrtc-demo.vcap.mozillalabs.com/mobile.html): 05-18 19:16:42.274: D/WEBRTC(9185): VideoCaptureDeviceInfoAndroid 05-18 19:16:42.274: D/WEBRTC(9185): Camera 0, Facing back, Orientation 90 05-18 19:16:42.274: W/CameraService(129): CameraService::connect X (pid 9185) rejected (existing client). 05-18 19:16:42.274: E/WEBRTC(9185): Failed to init VideoCaptureDeviceInfo exception: Fail to connect to camera service 05-18 19:16:42.274: D/WEBRTC(9185): Failed to create VideoCaptureDeviceInfoAndroid. 05-18 19:16:42.274: D/WEBRTC(9185): VideoCaptureDeviceInfoAndroid 05-18 19:16:42.282: D/WEBRTC(9185): Camera 0, Facing back, Orientation 90 05-18 19:16:42.282: W/CameraService(129): CameraService::connect X (pid 9185) rejected (existing client). 05-18 19:16:42.282: E/WEBRTC(9185): Failed to init VideoCaptureDeviceInfo exception: Fail to connect to camera service 05-18 19:16:42.282: D/WEBRTC(9185): Failed to create VideoCaptureDeviceInfoAndroid. After fixing Bug 863290, trying to probe the Video Capture capabilities no longer silently fails. From a quick read, calling SetAndroidObjects causes a VideoCaptureDeviceInfoAndroid object to be constructed, and that tries to get camera capability info on construction, which fails when someone already has the camera locked. The webrtc-Android code architecture needs some work here...
Simple fix suggestion by jesup: just bail out of SetAndroidObjects early if the objects are already set up.

Looks like I still can't get a call to work between FxAndroid and Desktop Firefox. I'll file a new bug on this.
