Good info fellas

also I find related info from Gyan at
https://superuser.com/questions/1512575/why-total-frame-count-is-different-in-ffmpeg-than-ffprobe/1512583#1512583

Thanks again Gyan

https://stackoverflow.com/questions/13855533/how-to-decode-video-data-from-specific-position-in-byte

frame at a given byte position

cheers
