I just noticed i didn't share the ffmpeg, but i have alot of those logs, which one do you need/want?

I want the ffmpeg_transcode logs.

Also, do you have IOMMU enabled in your BIOS?

There isnt a setting called IOMMU, but after what i can read VTx/VTd is the same and that is on
Its called "Virtualization Technology (VTx/VTd) " Which is enabled

I have found out that it is specifically HEVC SDR that i cant transcode. But according to ,https://imgur.com/a/WzBo60y, your docs i should be able to. Even if i disable hevc transcoding it doesent work. I have a Intel® Core™ i7-6700 Processor

Looking at the screenshot from your first post, you have HEVC & HEVC 10-bit enabled for HWA. Make sure to disable them if this is the case.

Oy. My bad. I missed that. Skylake CAN decode 8-bit HEVC, but not 10-bit. And it looks like the problem files are 10-bit.

Okay, first of all, i was really tired when i wrote that and didn't double check things. On my production server, it cant play files at all if i have QSV on and have both HEVC Disabled. ¨

On the test server that i have setup it can play files if i have QSV on and disabled HEVC 8 bit AND 10 bit. If i turn these settings on, at my test server https://imgur.com/a/oYNkDos Then it dosent work.

This is the newest FFmpeg transcode log from the production server:

Have you tried setting up VAAPI instead? I wonder if that would work for you.

This might be the answer.  I recall some other Skylake users having to switch to VAAPI.  Did Intel deprecate support for that generation or something?

Maybe, but I can't really confirm that. The main reason I suggested VAAPI was because the last image he shared was showing an error with not being able to use VAAPI.

Okay, on my production server. If i set it to VAAPI, now i can play all other formats than HEVC SDR. Even if i disable 8 bit and 10 bit in the HW settings

On the test server i have, it is the same problem.

If it matters, it's the two same series i test on, although not always the same episode

Ugh. I had a 6700K and Z170 board lying around for years until a couple months ago.

I can't think of anything logical to explain what is happening. But you're not the first Skylake owner to have unexplainable transcoding difficulties.
