Transcoding causes crashes related to openCL not found after update

[carne_asada]

After I updated to   10.9.6

I get this error  and the client also crashes  or hangs .  Any thoughts?  I'm running this on a docker container on synology and confirmed the  dev/dra entitlements are correect.

Which docker image are you using? If you are using the Linuxserver Jellyfin image, you need to add their OpenCL mod.

https://github.com/linuxserver/docker-mo...encl-intel

[carne_asada]

I'm using the standard jellyfin image.  I've also tried linux server with the mod and get the same error.

If I disable tone mapping It no longer crashes  but also is no longer capable of transcoding without sutter.   I've tried with both VAAPI and  QVC

[TheDreadPirate]

What CPU/GPU do you have? And what OS is the host running?

[carne_asada]

CPU is Celeron J4025 on a Synology NAS DS220+ It's running the latest version of DSM.

[Efficient_Good_5784]

CPU is Celeron J4025 on a Synology NAS DS220+  It's running the latest version of DSM.

That's the issue. Synology is using an old Linux kernel that doesn't contain the necessary files for Jellyfin to properly tone map content.

If I disable tone mapping It no longer crashes  but also is no longer capable of transcoding without sutter.   I've tried with both VAAPI and  QVC

The CPU is quite underpowered. Synology purposefully uses these to lower the power draw of the NAS as well as lower temperatures.
It's perfect for basic NAS functionality, but will struggle with transcodes if the CPU is used instead of the iGPU. Especially if you're trying to tone map 4K videos.

Your only option is to wait for Synology to release a DSM version that contains a new enough Linux kernel, or just have tone mapping turned off.
Though Synology is generally slow with updating things. It may be a long while before something like this happens.
