Comment (by Balling):

 I created this https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/20091

 but we need a sample. From here or arteficially created:
 https://video.stackexchange.com/questions/28358/ffmpeg-identify-non-idr-
 frame-i-frame-as-keyframe

 I propose this as well (not in my code): should we maybe create a std
 strict condition that manadates that it cuts at IDR frames only, as it is
 requires by the H.264 pdf standard? This is separate from this bug where
 Open GOP is incorrectly cut at I frames that are not IDR
