HDR not always initiated - christiaanvdlaken - 2024-06-13
Hello,
I have a strange situation. I have this 4k DV HDR10 movie that I played. It didn't seems very crisp and also didnt initiate the HDR10 functionality to my surprise so I decided to check out Stremio to see if other files were any better. I happened to see the exact same file so I started it up to see if I could notice any difference. Through stremio it does initiate the HDR and the same file looks much crisper and also the colors seems better.

it does not support DV but it should have a fallback to regular HDR10 ?
I have transcoding enabled
Any idea how this is possible? is it my tv or my server or jellyfin ?
RE: HDR not always initiated - TheDreadPirate - 2024-06-13
The log you included looks like a failed tone mapped transcode. Do you have the Intel OpenCL package installed?
With regards to HDR10 fallback. I've never seen Jellyfin/exoplayer fallback to HDR10 for my DV content. So I opted to remove the DV layer and go straight HDR10 for all my HDR content.

Thanks for the quick reply
Ok I already thought of filtering out DV on arr stack so will do that. regarding the OpenCL package, i have proxomox and jellyfin is running on a ubuntu VM I have the gpu passthrough but should is install the OpenCL package on the ubuntu vm then ? not sure if i have it so any way to see if it is installed ?
RE: HDR not always initiated - TheDreadPirate - 2024-06-13
sudo apt list --installed | grep intel-opencl-icd
Is Ubuntu a VM or a LXC? If a VM, I think this needs to be installed in the VM. If a LXC then it needs to be installed on the host.

Try adding Nvidia's repo to your apt config.

I vaguely remember someone with a similar issue and they had to install a newer version of the nvidia container toolkit than was available in Ubuntu's 22.04 repo.
