Hi.
I have CoreELEC 19.2 running in a S905X3 device, connected to a 2019 Sony Android TV.
I have noticed in some 1080p videos encoded with HEVC in 10bit and HDR10, that the image “flashes” from time to time.
Here is the MediaInfo of one of those videos:

My TV is configured with HDR set in “Auto” mode.
However, if I fix the TV HDR mode in “HDR10”, the video is played perfectly. Also, I play it directly in the TV itself with Emby Android app, there are no flashes at all.
That’s the reason I think that the HDR information is not well transmitted to the TV and, somehow, it doubts, disabling and re-enabling the HDR10 mode periodically, because it is HDR10 indeed.
Except these series of videos, I have been playing 2160p HEVC 10bit HDR10 movies without this kind of problems.
What do you think?
Thanks!
