Author: Mans Rullgard <[email protected]> Committer: Mans Rullgard <[email protected]> Date: Wed May 30 04:04:54 2012 +0100 h264: allow cropping to AVCodecContext.width/height Override the frame size from the SPS with AVCodecContext values if the latter specify a size smaller by less than one macroblock. This is required for correct cropping of MOV files from Canon cameras.
