Transcoding won't work when tonemapping is enabled (J5005 + Unraid)

[Reytec 2]

I'm running a Dell Wyse 5070 with an Gemini Lake Intel J5005 (UHD Graphics 605) and Unraid 6.12.6

My server can't transcode media when tonemapping ist enabled, this problem only occurs when using QuickSync (VAAPI works). but QuickSync is the prefered method since its more efficient.

Recently i tested Plex and had a similar problem, with tonemapping enabled the Server falled back to Software transcoding which causes massive load on the CPU and lagging playback.

 

I tested both the official emby stable image and the beta with following results:

QuickSync Transcode - disabled Tonemapping - Works

QuickSync Transcode - enabled Tonemapping - Broken Playback

VAAPI Transcode - enabled Tonemapping - Works, but is inefficent on that CPU

 

I tried to transcode different 4k material with Dolby Vision and/or HDR, always with the same problem.

Here are the logs after some Playback attemps:

It's recommended to provide more info, as it explain in this thread:

Thank you.

VAAPI tonemapping is only working when the VAPPI HW method is selected. The VAAPI Extra-T OpenCL method also causes broken playback.

That IGP doesn't support HDR video.

That is why your transcode tonemapping of HDR is failing.

Interesting. If this is true then it sounds like we need to improve the detection so that it never attempts to do it in the first place.

That's nonsense. As you can from the report and the provided logfiles, VAAPI tone mapping is working.

I found posts with similar problems on the plex and jellyfin forums. There is actually a issue with newer linux kernels in combination with the j5005 and similar cpus.

I'm now running Ubuntu Server 22.04 with Kernel 5.15 via VM on Unraid and i can confirm that QuickSync tonemapping works as intended.

Not optimal but at least a workaround for now.

@softworkzIs it possible that this is the same problem that we discussed here?

In your hardware log it says GeminiLake UHD Graphics 600. Almost the same as mine. It has to be affected by the same Kernel issue.

[MrMackey 33]

Yes, it looks like it, at least now we know what the probable cause is.

Take it up with Intel, this has been discussed years ago

That's about the question whether HDR is supported on Windows 10 as a desktop mode. This is something totally different from video acceleration.

In other words: You cannot connect an HDR TV or monitor, but you can still transcode 10bit HEVC video.

@MrMackey @Reytec- Yes, this appears to be the same issue.

This might be resolved in the latest beta (28). We made some updates to the Intel stack and had successful tests. 

=> EDIT: It's in .27

Would you be able to (re)try with the beta?

 

@Reytec- Please note that you might not be able to go back to stable after upgrading, be sure to make a backup.

Not fixed in beta 27

I think i tested beta 27 already before creating this thread. But just to make sure i tried again right now.

 

This is running the Unraid docker under kernel 6.1.64:

@Reytechave you updated to Emby Server 4.8.10? Has that helped?

[Reytec 2]

Sorry for the late response, but I'm not using emby at the moment. Maybe someone else with similar hardware can test it. Would be great if it works with newer kernel versions.
