Dolby Vision detect or maybe playback issue from plex server

When I put a 4K HEVC Dolby Vision file on plex server and add it as source of my infuse, infuse detect this file is only 4K HEVC, but then I put this file directly into Infuse, it shows 4K HEVC DV correctly.

So what’s wrong with it or set source from plex just do not support DV?

Platform:

Infuse Pro 7.0.5(3689) on iOS 14.6 (iPhone 12 Pro) & iPadOS 14.6 ( iPad Pro 2021 12.9 inch)

The video file info showed as below:

Does it playback in Dolby vision on both? If playback runs properly the. I’m going to suspect that plex server doesn’t do meta data checks beyond HDR.

Agreed. Plex does not pass on DV tag.

The playback seems correctly or at least no color or other issue.

But it showed the hdr tag in Plex client but no HDR in infuse.

Think that has to do with how infuse handles HDR tags, DV files are not tagged HDR in the native app either, the feature request may have to do then with the HDR tags being pulled from Plex even though natively the file is actual DV HDR. @james :question:

This is correct. The file will pay back correctly with proper DV trigger.

The official plex client shows DV files as 4K HEVC even though they play back properly in DV. This is a limitation in plex server with how they show files in the library. This will need to be fixed by plex.

actually the plex app marks this file as 4K HDR HEVC

Not mine: I have two DV encoded webrips and one is 4K HDR HEVC and the other is 4K HEVC but both playback as DV.

Agree with that too, some inconsistencies are there in DV metadata fetching with Plex.

Correct.

When connected to Plex, Infuse will rely on the metadata and specs provided by the Plex server for a particular video, instead of generating its own.

I guess DV videos are technically HDR, but Infuse will use these 2 terms for 2 different video types…so displaying HDR in this case wouldn’t really be accurate with how other videos are handled.

Regardless of what tags are displayed in Infuse, the playback pipeline will use the actual video specs to determine the best way to play the video (and switch frame rates and dynamic range accordingly).

Hey,

I just noticed, that when viewing DV show or a movie remotely on plex, it doesn’t show the “DV” letters, marking it as DV file. However, when I download the file locally, it properly tags it.


EDIT: I just also noticed that it says, the file is DD+ 5.1 when viewing remotely, and DD+ 2.0 when synced locally.

EDIT 2: iPhone 12 Pro, iOS 14.6, Infuse 7.0.8
