I have tried avcodec_align_dimensions2. It introduces corruption on a
gt220 which was fine before.
Expanding the video surface in horizontal direction will always result
We are able to duplicate this issue with dxva decoder.
Why do you think the size of a video surface should not match the
original coded size of a frame?
Did you try this sample on a ION platform? The problem won't show on e.g. GT220.
