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?

Answer 1

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.
