SOLVED: Intel QSV HW Not working

[Raymagini24]

Hello I have a Windows Jellyfin server
CPU:Intel i5-7500
GPU: Nvidia 1060

I've used Intel QSV Acceleration for a while but it stopped working this weekend, I tried update ffmpg to the current one, roll back to the version 5 as I found in a similar thread, checked my paths on windows from another thread but nothing works.

I tried switching to Nvidia NVEC but that doesn't work either.

I've seen people talking about changing things from a terminal but I'm not sure if I can do that from Windows...

Any sugggestions? Thank a lot in advance.

These are my logs:

Windows will sometimes update/downgrade GPU drivers for you, but it can occasionally break functionality.

Please install the latest drivers from intel.com and revert Jellyfin FFmpeg to 7.0.2 and try again.

Hii! I already did both and same results exact same error.

Also noob question, for the Hardware I use, CPU:Intel i5-7500 and GPU: Nvidia 1060 should I still stick with the Intel i5 or try to fix to use the Nvidia NVEC?

I just noticed that you are using vanilla ffmpeg instead of Jellyfin ffmpeg. Which would explain why both QSV and NVENC are failing.

If you do not need that version of ffmpeg, please uninstall it. If you do need it for use outside of jellyfin, reconfigure windows so that calls to "ffmpeg" are routed to jellyfin-ffmpeg.

[Raymagini24]

That sounds perfectly logical, I thought I moved the jellyfin-ffmpeg... maybe I'm doing it wrong. I only use that device for Jellyfin and storage so definitely don't need ffmpeg for anything else. If possible, would you share some guide on how to uninstall it correctly?

Thanks!

[TheDreadPirate]

Just go to the Add/Remove programs in the control panel and remove "ffmpeg". After that is done, calls to ffmpeg should go to jellyfin-ffmpeg.

[Raymagini24]

Nothing comes up in the control panel or the add/remove programs. Even when typing ffmpeg in the star menu nothing comes up. I can also verify that if I had to install it in order to have it I've never done it... The only thing I did was download the jellyfin-ffmpeg, extract and replace everything in the Jellyfin folder.

Also video playback work if I disable hardware acceleration, of course is incredibly laggy and can barely transcode 1 video, enabling HW accel on Intel or NVEC both fail.

If you open Voidtool's "Everything" app, do you see ffmpeg.exe listed?

[Raymagini24]

I only see ffmpeg on jellyfin and the different downloaded zip files I've tried.

[TheDreadPirate]

I see that you have a custom ffmpeg build in your downloads, which matches the version that Jellyfin is calling.

Read the guide below. Start at step 3 to see if you've setup an environment variable to use this custom ffmpeg build.
