Thanks Nicolas for review ! I agree with it that the patch can't solve the case that "not all frames have the same orientation". The only way I can think of (correct me if I am wrong) is a filter that dynamic do tranformation per frame. From a technical perspective, this kind of media is absolutely possible. For example motion jpeg consists of jpg with different orientations. But I assume it is rare with my limited knowledge. What do you think?
