This should not have been pushed. If it had been posted for review, I
would have had a chance to explain to you that filters are not supposed
to use information from the frame rate, as it is not negotiated and
supposed to be only indicative.

Filters that need matching timestamps between frames on separate streams
should use framesync or an equivalent logic.
