So, this just does not work. I tried to re encode with nvenc in hevc in
MPEG TS a film (with -bf 0). https://drive.google.com/file/d

First: note that
http://andytather.co.uk/panda/Files/Video/HDR/LG%20Chess%20HDR.mp4 is NOT
mp4. It is MPEG TS.
Second: the problem with TS is persistent. I tried to encode that MPEG TS
in mp4 and in mkv with just "-acodec copy -vcodec copy" and it became
good, then I again "-acodec copy -vcodec copy" back to ts and it was again
broken. So this is very strange, also broken for VLC and Media Player
Classic (with LAV)... But good in Potplayer and "Movies and TV"...
