I tried to extract frames from 10 bit video using ffmpeg:
ffmpeg -i 10-bit-video.mp4 -pix_fmt rgb16be test_%03d.png
and that's 16-bit png with max value of 65535
how to get corresponding 10-bit RGB value (0-1023) from extracted 16-bit PNG?

Divide by 1024. – Gyan Aug 18 '21 at 09:28

why divide by 1024? 0~65536 / 1024 is in 0~64 – Yineng Xiong Aug 20 '21 at 08:38

That should be the case, Gyan, but it is not. https://trac.ffmpeg.org/ticket/7978#comment:6 in ffmpeg just converting 10 bit 940 value to png does not get you to 60160. – Валерий Заподовников Aug 31 '21 at 04:08
