Hi Dave Sparks ! Thank you very much. I　think video recorder is another story . Now How to using video plane to display video is problem , It happens in: 1. video playback . 2. Camera ViewFinder. 3. Video recorder preview (also a view finder)
Do you have plan to give a method to solve this case together ? Using video plane will give performance improvement. Basic graphic plane for UI element while video plane for video output .
