I tried -fps 50 as it is required for -vf tfields 4:1 (which is a similar
way of deinterlacing). Behavior is quite strange :

with only -ofps 50 : lots of "duplicate frame(s)" messages on first
without ofps and fps : no messages, but video is played in 50% slow motion
(obviously, the output video is 50 fps)

with fps and ofps : no message en first pass, "duplicate frame(s)" messages
on every frames on second pass.
