In theory, input caps can be updated anytime at non-keyframe or sequence boundary, such as HDR10 metadata, framerate, aspect-ratio or so. Those information update might not trigger ::new_sequence() or subclass may ignore the changes. By this commit, input state change will be tracked by baseclass and subclass will be able to know the non-decoding-essential update by checking the codec specific picture struct on ::output_picture() Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/3328>
