New HDR info

[jonomite 29]

One of Emby 4.6's new additions is "Add HDR info to video stream titles."  After the upgrade, I see that the video information for my 4K titles includes the "HDR10" label. My questions are (1) is this the new HDR info; and (2) are there plans to make that information more detailed by, for example, including HDR10+ or Dolby Vision info?

Thank you.

HDR10

Dolby Vision

Huh. I am not seeing the "Codec Tag" field for my DV files, though they are in an MKV container. Does Emby only recognize DV in an MP4 container?

Also, I do see HDR10 display properly, but I was asking about HDR10+.

dvhe for dolby vision

for HDR10+ you would look at the profile.

Emby is basically just reporting things as tagged.

I understand dvhe refers to Dolby Vision. The issue I'm reporting is that I have media encoded with Dolby Vision dynamic meta data that is not being reported by Emby. It appears that in the screenshot you attached, the file is in an MP4 container. The files I have are in an MKV container; I wonder if that's why I am not seeing the dvhe tag?

Also, I do not believe "Profile" refers to HDR10+. My understanding is that refers to HEVC's Main 10 profile.

If you could provide screen shot of what you see in Emby's detail screen and what you see in a 3rd party program that would be appreciated.
Right now we can only report back what we get from ffmpeg's ffprobe but we can see what we can add if needed.

Here is a screenshot from MediaInfo.NET reporting on an MKV file that has both Dolby Vision and HDR10+ metadata.

 

Here is how Emby reports the same file.

I've done a little more research, and while I can easily be mistaken, it appears to me at least that Emby is displaying the "Codec ID" tag, as shown in the MediaInfo.NET screenshot above. I wonder if the better tag to use to display HDR info is the HDR format tag.

Good info.  Could you do one other thing?  Let's see what ffmprobe shows:

ffprobe -i "movie path here"

you can find ffprobe in your Emby system directory.

This info/feature has been asked for many times - but the only enhancement since the request is displaying the HDR10 'info' after the HEVC codec - but of course that is incorrect for anything that is HDR10+, HLG or DV...

Identifying these streams is easy enough in something like MediaInfoCLI - that also includes identifying all the object based Audio streams such as THD Atmos and DTS-X.

However, as emby uses ffprobe, this does NOT identify the above info, and thus emby cannot catalogue it.

Manual hacking the db or api is the only way to get the more advanced features displayed ..

To add - if emby did a lookup of the HDR type - then it could display the correct info.  However, currently if you replace the value in the field/db with anything but 2020 - it displays nothing at all, so it only appears to recognise HDR10 only.

HDR Type    Identifier
HDR10        2020
HDR10+        2094-40
Dolby Vision    2094-10
HLG        2100
AD-HDR        2094-20 + 2094-30

@rbjtech

Thanks for the responses. I missed those earlier threads. Looks like I'm experiencing the expected behavior on this.

@jonomite @rbjtech I wanted to mention that the RPDB project does support matching both HDR and Dolby Vision for videos properly: https://ratingposterdb.com/

The RPDB Folders app needs to be used for now in order to detect HDR / Dolby Vision and other detailed video info which would be added as badges to the movie / series posters directly.

Poster badges are only supported with Tier 3 though.
