Not quite. #8820 is about ffprobe skipping I-frames when printing, which
might be the correct behavior, depending on the definition of what is a
keyframe.
My sample video has I-frames that are not IDR. When splitting at those
I-frames, the second part of the split cannot be played properly (the
first few frames are not playing). To fix this I have to manually specify
a segment_times that is close to an actual keyframe (IDR), and ffprobe
reports those same IDR as keyframe=1.
