USB Camera in JB 4.2.2-1.0.0 SabreSD

I've enabled the USB camera on JB 4.2.2 SabreSD board using the following patch.  When I test it with a Logitech Webcam C250 and the "Camera" app, I see a lot of video glitches.  Pointing it at a static location, I see glitches every 5-10 seconds.  And if I wave my hand in front of the camera the video glitches are worse.


Is there a way to improve the USB video decoding performance?
