RE: Converting Dolby Vision to HDR10 - gnattu - 2025-02-19
The one-liner is known to work bad with the mkv muxer of ffmpeg because ffmpeg's own mkv muxer tries to do too many smart things during stream coping and it will fail the process when the dolby vision metadata is removed for some videos. You have to remux to a better implemented muxer like mp4, and then from that mp4 to remux back to mkv.

Personally, I wouldn't bother converting DV5 videos to HDR10. Some Android TV devices use mediatek SoCs, and some of those models have driver bugs that break Dolby Vision 7 and 8. And one of my devices also has a mediatek chipset.
That is in addition to my re-encoding all my media to AV1, which doesn't support DV 7 or 8.
Yes, you are right. And I gave up
Tried all possible combinations of dovi_tools conversion from 5 to 8 prior to using ffmpeg and tried using ffmpeg on original files but with old method and Mp4 intermediary. No result. Even on first steps video was all purple-ish.I figure its because DV5 is using properitary colorspace and not many tools are capable of reading it and doing anything about it.
I even read that owners of Dolby Vision standard have IP patent on the method of converting DV5 to HDR and thats why there are no tools to do it avaliable to public.
