Request - Dolby Vision metadata support #7

Open five82 opened 1 month ago

five82 commented 1 month ago

Support for automatically copying Dolby Vision metadata from the source, similar to how the --hdr parameter currently works.

For now, if you could add support for the svt-av1-psy --dolby-vision-rpu parameter so we can inject the metadata from an RPU file, that would be great. Thanks.

the problem is when you want to chunk. I would have to extract the metadata and split it along chunk borders that are saved in frame numbers (annoying to deal with bc constant frame rates are not a given). Hoping everything stays synced in the process, definitely possible but I would need to explore different ways and find the easiest cleanest one. prob exclusively involving ffmpeg

Thanks. Makes sense. Once they add AV1 support to dovi_tool, I'll be able to mux the metadata after the encode.
