Dolby Vision Profile 20?

[dprestegard]

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.

• I looked for a similar issue and couldn't find any.
• I tried with the latest version of GPAC. Installers available at https://gpac.io/downloads/gpac-nightly-builds/
• I give enough information for contributors to reproduce my issue (meaningful title, github labels, platform and compiler, command-line ...). I can share files anonymously with this dropbox: https://www.mediafire.com/filedrop/filedrop_hosted.php?drop=eec9e058a9486fe4e99c33021481d9e1826ca9dbc242a6cfaab0fe95da5e5d95

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?
