Plex Dolby Vision Mkv
Plex Dolby Vision Shield Pro

When is dolby vision going to be supported on the shield? I have many TS and mkv files that play in plex with DV, but same files in Emby just show HDR. Im using Nvidia Shield with whatever latest version from store is. Doesn't Dolby Vision work in a m2ts container on the Oppo? Plex does work with m2ts but not ISO or folder format. As you've said DV metadata apparently does not work in an MKV container. I'm not sure how to rip discs with multiple playlists into an m2ts format. Also, does the m2ts format retain chapters and subs?

There has been some extremely interesting development regarding Dolby Vision. With makeMKV 1.15.1 the developer added DV support for .mkv.

'While not announced on release notes page, MakeMKV 1.15.1 (released 15.4.20) should correctly recognize and preserve Dolby Vision streams in MKV file. '

“Dolby Vision is not a separate codec, but rather a (HEVC) stream extension - DV data (EL+RPU) are encoded in separate NAL units, according to Dolby spec.
The presence of DV data can be checked by several different methods - most obvious are:
(1) DV descriptor in codecprivate data (there is an “standard” of storing additional elements in codec private for AVC and HEVC streams, that was used for ages since 3D MVC video) or
(2)presence of DV RPU unit in first frame.”

And feature request for the mkv format:

Once makeMKV implements that method I’ll provide a sample and hope that you can implement it in infuse.
