 Replying to [comment:23 oromit]:
 > ffmpeg.c just does not support a decoder changing the framerate of a
 video. Making it so it does is a major undertaking.
 > The only way around it is to use the deinterlacer via API from an
 application that supports it.

 It used to work with -r XX on output before the above mentioned commit.
 There is no way to make this happen again? Why it worked before and
 doesn't work now?
