            • Test was landed in this change assigned to developer who landed the tests
            • Seems like an actual regression in video playback for ARM.
            • Regression is from Chrome side between 45.0.2416.0 and 45.0.2417.0. Reverting the video changes in this diff does not seem to fix the issue. Trying to revert the WebRTC roll, but its failing locally. I've reached out to the WebRTC sheriff
