Thanks for the reply. You are right that the initial versions of the standard did not specify a 10bit version of the MV profile. However, in July 2023, a proposal for the "Multiview Main 10" profile was made, and currently there are many encoded HDR videos in this profile being streamed to Apple Vision Pro. The HTM reference SW <https://vcgit.hhi.fraunhofer.de/jvet/HTM> already has the support (search for "JVET_AE0295"). The Dolby FAQ site <https://professionalsupport.dolby.com/s/article/Dolby-Vision-Profile-20-FAQ> also mentions this profile. Then there were other profiles ("Multiview Extended" and "Multiview Extended 10") proposed, and since "Multiview Extended 10" can be a superset of "Multiview Main 10", the latest standard (July 2024) <https://www.itu.int/itu-t/recommendations/rec.aspx?rec=H.265>, ended up only including the "Extended" profiles. For the "Extended" profiles, you can search for "JVET_AH0046" in the ref SW. Given that there are already many encoded videos with the "Multiview Main 10" profile, Apple has submitted a proposal (JVET-AJ0213 in Oct 2024) to bring back the profile into the standard. _______________________________________________ ffmpeg-devel mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
