i think what you want to know is the number of keyframes and
this is practically never known at the time at which the header
is written
the number of frames also is often not known
and even the duration in seconds is not known in many cases
(mpeg-ps/ts and any form of grabing which the user aborts at his
choice ...)

I do not agree with what you have to say, but I'll defend to the death your
right to say it. -- Voltaire
