Request to generate Dolby Profile 8.4 like Dolby Profile 8.1 #144

It seems, level 6 is unnecessary

Maybe one day, but I have no way to test.

I've been trying to make Dolby Vision 8.4 on Windows. The way I figured out is to make two "similar" PQ and HLG videos, use madMeasureHDR and dovi_tool to make Dolby 8.1, and then inject the 8.1 file to HLG.hevc. I know this sounds crazy and doesn't make sense, but I also don't have a better way. Is there a way to regenerate RPU.bin from the exported RPU_export.json file, so that I can manually delete level6 to test.

My native language is not English, all of the above are google translated. Sorry for any offense.

No.

Profile 8.1 is incompatible with HLG base layer, we need to generate an RPU with defaults like iPhone recordings.

It seems that I know too little about Dolby Profile, thank you for your reply, looking forward to a way to implement this function one day.
