I'm not sure what your answer means.
I understand that "A keyframe" is a random access point. The flag in
ffprobe's output seems to always be "1".
I thought it might be the same as "intra" in FFV1.3's ffprobe output,
but it doesn't go to "0" when GOP>1.

True.
I just found it a bit confusing to have "slices" mentioned in FFV1 <
version 2.

Thanks for clearing that up.
