Subsequent frames, the delta frames, only contain the information that has changed. Keyframes will appear multiple times within a stream, depending on how it was created or how it’s being streamed.

2 I-slice. The H.264 format actually supports two different types of I-frames – traditional keyframe "IDR" I-frames which represent suitable restart points (IDR stands for "instantaneous decoder refresh"), and other, lesser, non-IDR I-frames in which frames after the non-IDR I-frame can still refer to frames before the I-frame, meaning the non-IDR I-frame can't be used as a restart point, but it's 2008-07-24 0 means current frame is identical to previous frame, and 100 means it is completely different. keyint is the maximum permitted distance between two keyframes; minkeyint is the minimum. IDR (instantaneous decoder refresh) frames are keyframes such that no future frame requires to refer to a frame earlier than the IDR-frame for decoding. To get the frame type for specific frame (e.g. frame 8) you can extend it to this: $ ffprobe video.mp4 -show_frames | grep -w -E 'coded_picture_number=8' -B 1 pict_type=P coded_picture_number=8.
