   We use NUC12 platform for hardware HEVC-QSV encode and decode. At least for NUC12 which has Xe graphics these are the guidelines.

   1. make sure to use the latest release or Continous AppImage
   2. Use kernel 5.19 or later
   3. Install OneVPL

       wget -qO - https://repositories.intel.com/graphics/intel-graphics.key | sudo gpg --batch --yes --dearmor --output /usr/share/keyrings/intel-graphics.gpg
       echo 'deb [arch=amd64 signed-by=/usr/share/keyrings/intel-graphics.gpg] https://repositories.intel.com/graphics/ubuntu jammy legacy' | sudo tee  /etc/apt/sources.list.d/intel.gpu.jammy.list
       sudo apt-get update
       sudo apt-get -y install intel-opencl-icd intel-level-zero-gpu level-zero intel-media-va-driver-non-free libmfx1 libmfxgen1 libvpl2
       
       sudo sh -c 'echo "options i915 enable_guc=2" > /etc/modprobe.d/i915.conf'
       sudo update-initramfs -u
   

   4. on decoder use --param use-hw-accel,force-lavd-decoder=hevc_qsv
   5. User that runs the UG app must be member of video,render and audio group.

   I think that is it.

   Thanks I will try this now. I'll have to update the kernel to get there.....

   But really, for HD, CPU encoding/decoding, should be no issue on modern CPU. QSV just add headache and less quality. We only use it for UHD, everything else is CPU.

   It's a 10th gen box, and the CPU based h.264 is fine. I am trying to squeeze in hevc for some unique use cases when desperately needed.

   2K or under, x265/hevc CPU only is fine. I've never been able to get UHD 12bit CPU only though. What unique cases do you have?

   Well, thats interesting. I "believe" the machine is strong enough to handle it, but I have never been able to reliably get hevc to encode and decode on the machine. Maybe I should have mentioned that in the first place. My goal is encode and decode in one box. I can see my core usage is about 5 on a 8 core box, but it will never go up to full 100% usage for it. I'm assuming thats a hyper threading issue, because in theory its a 4 core machine, but hyper threaded to 8.

   I doing two way SDI tunnels over the internet with my own error correction algorithm "which is better than SRT BTW..." and I want to have one box that will do encode and decode at the same time.

   Oh... that is a lighter CPU than I thought. We use Ryzen 16c/32t. What is different about your EC and how is it better than SRT?

   @TheSashmo Not sure what your budget is, but a NUC12i7 utilizing QSV can encode/decode 4K UHD easily, and you can get one all in for around $800.

   I'll pick up one of those to see if it eliminates my problems, but no matter what I do, I am seeing skipping frames on my output. Even on a server setup I get the same result. I'm starting to get frustrated a bit. Lets see if that NUC gets me over the hump. Thanks @alatteri . You going to NAB?

    NAB isn't in the plan. I know pre-COVID some of the UG would go. Maybe they'll be back this year. But if you're in LA, buzz me up.

    @alatteri not to clutter up this thread, but I will be LA after NAB. Lets meet up for a coffee! Not sure if I ever saw a DM option in github. But DM me? LOLOLOL.

    Email me XXXXX

    I've removed my email address, to prevent data scrapers, now that Sashmo and I have connected. The rest of this thread can go back to the original issue.
