My goal is to search keyframes in AVI file. I parse it and get all the data chunks for the video stream, but how can i find in there info about frames themselves - whether a particular frame is a keyframe or not?

  • meta: how is this question "unspecific"? it clearly states what it wishes to do and what it did already. could we reopen it or make a more specific comment on what's wrong, should there be anything. – n611x007 Jul 14 '14 at 15:18

The keyword is AVIIF_KEYFRAME. See http://www.opennet.ru/docs/formats/avi.txt

AVIIF_KEYFRAME

Indicates this chunk is a key frame. Key frames do not require additional preceding chunks to be properly decoded.
