videos abnormal frames parsing?
Comment:
͏ I guess the cause might be OGOP (Open GOP).
͏ What are the interpreted encoding configs (returned by "libx265")?
͏ (or "Encoding settings" of MediaInfo)
͏ Should:
͏ `ffmpeg -y -v debug -hide_banner -nostdin -nostats -f lavfi -i
"testsrc2=1920x1080:30:d=15" -c:v libx265 -preset slow -crf 19 "Out.mkv"`
͏ ; reproduce then?
͏ To explicitly disable OGOP, add: `-x265-params "open-gop=0"`
͏ More tools for output analysis:
͏ `ffprobe -v warning -hide_banner -threads 0 -show_entries "frame"
-select_streams v:0 -of "xml" "Out.mkv" -o "Out.mkv.xml"`
