Yes, the pseudo vout filters must backport them to their vout destination and
it is not yet done.

As the AspectCallback is used to specify the aspect ratio of the displayed
video, it works.
But for vout filter, you cannot be sure that it does not have to modify/use the
So each vout filter should be modified to support ASPECT_CHANGE flag.
