One way is to use ffprobe -show_frames

for example:

ffprobe -show_frames some.mp4

...
[FRAME]
...
key_frame=1
...
[/FRAME
...

ffprobe is from ffmpeg. probably avprobe from libav also.

I quick method do browse iframes is to open the video in Aegisub. It allows you to seek to next/previous keyframe in the video by pressing shift+left / shift+right (the framenumber field in the GUI has a turquoise color when you are on a keyframe btw).

Count of iframes is given in stats of tools like Avinaptic, but that sadly won't give you the number of a specific keyframe. I think mkvinfo (part of mkvtoolnix) also gives a breakdown of keyframes with timestamps.

Thank You Very Much...

any way to view whole frames in a column chart like graph (like in bitrate viewer)...

like each frames in different colors or any method that can distinguish I frames.
I remember very old Dr.Divx had something similar that shows keyframes... Something like that...
!?

Try GSpot (search it in videohelp page). Is old but good for view in color frames structure.

Edit: Ups, Oh My God, does not work with h.264, sorry. Better try with VideoInspector, I've never used (download it in softpedia, portable version).

Edit2: look Avinaptic:

Here
