Thanks for the insight. I am using surfaceview to render video stream and I cannot use anything other than surface view or video view. My application requires me to display multiple cameras on a screen within a scroll view. When a video is playing and I scroll the window, it makes a big hole on the window. But if we stop the feed, it gets back to normal.
Please advise.
