MPlayer for pulldown-stream writes something like 
"Pulldown detected, changing framerate" which I

But otoh, it is a known limitation that FFmpeg does 
not handle soft-pulldown very well, so the output 
will not give a lot of information, I just wanted 
to describe a possibility to show the issue esily.

issue / question where it was useful.
