Dolby Vision Files not recognized

[Dan]

I have several test clips that contain Dolby Vision. One (in MP4 container) appears in Serviio and plays fine, including triggering the DV label on my display. Another (TS container) appears in Serviio and plays but does not trigger DV or HDR on the display. The third (also in TS container) appears identical to the other TS file, but Serviio doesn’t even display the file under any presentation. Media info for the MP4 file, the TS file that plays but no DV, and the TS file that doesn’t display in Serviio.

This is the only information in the log for the file not displayed:

2022-06-05T17:24:30,592 WARN [MetadataExtractionCoordinator] Skipping processing metadata for an unsupported file (F:\Test Videos\dolby-vision-lg-earth.ts). Message: Unknown video codec.

I also consider this log entry puzzling, as I have metadata extraction turned off for my Test Videos folder, so I wouldn’t expect this to appear for this folder.

Players tested are the TV’s native DLNA player (LG Nano85), Nvidia Shield using Kodi, and Roku Ultra 4800, all of which support DV. Serviio version 2.2.1, Windows 10 OS.

[Petr Nejedly]

this will probably require new ffmpeg version

[Dan]

I’ll try a different (newer) version. But since they aren’t being transcoded, I don’t know what FFMPEG might have to do with it. Of course, if you use it elsewhere for other purposes, that would be understandable.

[Priit Varik]

Check the output of ffmpeg -i on all those files.
I believe Serviio uses ffmpeg to identify media composition and codecs used.

For example, I see this message in my serviio log:

2022-07-20T00:22:07,875 DEBUG [FFMPEGWrapper] Invoking FFMPEG to retrieve media information for file: /Tests & Demos/Dolby Vision/RPU p8.1 L1.L2_cmv29.mp4

[Petr Nejedly]

can you post ffmpeg -i for the file (using ffmpeg 5.x) pls?

[Petr Nejedly]

especially the file that doesn’t appear. (eg /RPU p8.1 L1.L2_cmv29.mp4)

the one that doesn’t appear as Dolby Vision, is it possible it’s transcoded? I assume your files are picked up in profiles as h265, pretty much.

[Dan]

Petr, I’m traveling this week (currently sitting in the Denver airport), so it will be the weekend before I can do that. I did grab a new version of ffmpeg, which made some of the missing files visible. I think there’s still one missing, so I’ll check that one out.

[Priit Varik]

I get with ffmpeg 5.1.2 the following result:
