I do.

I wish MPlayer worked that way, but unfortunately it doesn't.  For MPEG-4 
(or H.261, H.263, or motion-JPEG) video streams, MPlayer would complain, 
and not play video at all, if the user did not use the "-fps" option.  My 
code now overcomes this by looking at (and buffering) incoming packets 
until it is able to figure out the frame rate; then it sets 
"sh_video->fps", and from then on the rest of MPlayer is happy.

For MPEG-1 and MPEG-2 video streams, on the other hand, MPlayer never used 
to require the user to use "-fps".
