Hi Group,
Can some body suggest me quick pointers to understand
the way "Frame Per Second"
is derived from an encoded video 3GPP file.

I have downloaded the QT player which displays the FPS
for the video Track. Also the QT player displays the
Movie-FPS under "MovieInfo" section.

I need to understand so that i can validate against
the QT player. If i am right I understand its a
function of "Sample_Delta" in the 'stts' box.
But need some more information.

sort of. the average frames per second is computed from the total frame count and overall duration. What you do for an 'instantaneous' value (actually, some sort of moving average) is for you...



Thanks and Regards, Nikhil
