Adds code to detect dead zone bars at the top and bottom of reformatted letterbox video (note that the code only looks at the top of the image and assumes any dead zone is symmetrical). Use of this to adapt rate control etc. will follow in a subsequent patch. Also counts other blocks (excluding the dead zone) that have no intra signal. The presence of a significant number of such blocks can be used as a identify that the frame may be artificial (e.g. animation, screen capture, graphics). This patch contains plumbing only and does not use the signal. Change-Id: I59bc93529cd4065416cef773e405fda3ae006a20 |
