Note that I think the demuxer is broken, too.
It does av_set_pts_info on the fps value in the header, but like
for WMV that value is just a kind of average, and rounded to
full FPS on top, it really should only set r_frame_rate and always
got by pts.
However I do not know if there are any (particularly the official test
streams) where this might cause an issue.
