I have installed IceWeasel to be able to test WebRTC.
root@radxa:~# iceweasel --version
Mozilla Iceweasel 31.3.0
Issue
To test the camera, I have installed luvcview which shows the video stream
... but when I try cheese, it does find the webcam, takes a lots of time to start the application but doesn't stream any video (black)
... on a test WebRTC session http://opentokrtc.com/test, it prompts to share the Lifecam and starts the session but there is no video stream
It does pass the getMediaStream. The camera lights up when I refresh the page and click on Share MS Lifecam, only there is no video stream. There is no error message on the browser console.
How can I troubleshoot this? This looks like a driver issue.
