Dolby Vision and Mediainfo HDR Format

Post by douchey » Fri Oct 09, 2020 9:46 pm

I've made a MKV using MakeMKV 1.15.3 using a source that has Dolby Vision. However, opening it in the latest MediaInfo 20.08 I don't see any reference to Dolby Vision in the video track HDR Format description. As far as I know, MediaInfo should support reading Dolby Vision data?

Muxing the Bluray m2ts to a TS file manually and reading it with MediaInfo, there is a clear reference to the Dolby Vision track.

Should MediaInfo be displaying the Dolby Vision info in MakeMKV mkv files? If not, how can I verify my MakeMKV created files contain DV without trying to play it on a Dolby Vision capable display?

I downloaded the latest version today and it is showing me the DV info for mkv files, I had to switch to Tree view to see this data.

Did you really need to make a new thread with all the other dolby vision threads around? You're on the wrong version of mediainfo, you need 20.09.

Can confirm, the new version of MediaInfo 20.09 (just released today Oct 9th) displays the DV info. When I checked last night with the previous version it didn't work.
MediaInfo change log:

+ MXF: detection of Dolby E hidden in PCM tracks having more than 2 channels
+ WAV: detection of Dolby E hidden in PCM tracks having more than 2 channels
+ CineForm: display of color space (including Bayer), bit depth
x WAV: more precise sample count
x SMPTE ST 337: catch of streams starting later than usual (probing increased from 4 to 16 PCM "frames")
x PNG: detection of additional alpha plane in color space
x MXF: detection of additional alpha plane in color space
x AVI: detection of additional alpha plane in color space
x MPEG Audio: was wrongly flagging Xing info tag as CBR
