Dolby Vision Profile 20? #2790

Open dprestegard opened 8 months ago

Hello!

I'm interested in packaging content for Dolby Vision Profile 20 for Apple Vision Pro.

This is basically Dolby Vision Profile 5 but extended for MV-HEVC. It would be awesome to be able to use MP4Box to package Profile 20 content into HLS CMAF.

Hi, looks great. Would it be possible to share with us some reference content? Also will you be able to play it back for validation?
