aos-AVP VS dovi_tool

Good idea, filed a feature request https://github.com/nova-video-player/aos-AVP/issues/890

Nova Video Player (version 2561170): Video player for local/network content with subtitle/metadata download support

They have Mac builds available for the latest release.

With a combination of dovi_tool by quietvoid and FFMPEG you should be able to inject the EL into the HEVC track you demuxed from RGB, then remux it back in using FFMPEG or mkvtoolnix.

There are ways to download the exact untouched copy of the stream from the server (not screen capturing) and extracting that DV metadata from the HEVC stream. Same goes for ripping discs and extracting DV there.

Yeah, the RPUs (which I honestly haven’t been able to even find out what it stands for, lol) can be converted using dovi_tool, which is how those hybrids are made. I’ve converted a few P7 movies from BR sources myself to get them to work in Infuse.

From what I gathered, it is possible to convert HDR10+ content to Dolby Vision using dovi_tool and hdr10plus_tool. But I haven't seen any tutorial on doing the opposite: taking the dynamic metadata from Dolby Vision and converting it to HDR10+. I have found posts with this question but with no solution. The replies to this one (from 2020) suggest that it is theoretically possible but that you would need more info about the DV metadata. Now, using dovi_tool, it is possible to extract the Dolby Vision metadata into a JSON file. But, while dovi_tool is able to generate a DV RPU using a JSON file containing HDR10+ metadata, hdr10plus_tool has no similar option. Is there any way to convert the DV metadata to something usable by hdr10plus_tool to inject in HEVC?

2) DoVi_Tool - This is a tool that uses ffmpeg to extract the DV layer and recode it back into the compressed output. (https://github.com/quietvoid/dovi_tool)

Step 2: Extract the Dolby Vision data with dovi_tool

It appears the player can't process FEL. I tried myself and it fellback to hdr10. I haven't been able to find an Android player app that can process FEL. You could convert FEL to MEL with something like dovi_tool but that might get time consuming.

You can look into a program called dovi_tool which can do all kinds of operations on DV tracks, including combining base & enhancement layers from separate tracks into a single track if I'm not mistaken.
