Hello,

I need a way to test if ffmpeg inserted the keyframes at the interval
requested using the -g parameter. The problem is no matter what value I use
for -g in my encoding command, even -g 1, the flash player I use acts the
same when I try to jump to different parts of the video, it will jump a few
seconds before or after the moment I actually choose. And I need a way to
track down what is wrong.

So how can I find the keyframe information for a mp4 video ? Can be ffmpeg
or another program..

Thank you,
Catalin
