Not sure if this is a bug. Steps: 1. Connect to http://jsfiddle.net/hsg9t3kf/ 2. Run "gUM!" and grant the permission to both video and audio devices. 3. Run "Stop!" to stop all tracks. After these steps, MediaStreamGraphImpl::ExtractPendingInput() is still called repeatedly. The symptom only occurs when audio track exists.
It only spins for a while.
