Hi! I’m unable to transcode a single 4k HDR to 1080p SDR with tone mapping enabled. With tone mapping enabled processor usage is around 40% and Tautulli shows transcode speed below 1, video buffers every few seconds. If I disable tone mapping processor usage drops to around 10% and transcode speed j…

Found it. You installed the SNAP package from the Ubuntu App Store. They changed the App store. It only dispenses SNAP apps now. SNAP packages can only use software and are confined to your home directory. (They are locked containers) Jan 27, 2021 01:02:47.449 [0x7f10a000e700] INFO - Plex M…

Tried it, didn’t work. Still get the same error. I can locate the libOpenCL.so.1 file in /usr/lib/x86_64-linux-gnu/

No customization, I’ve been wrestling with this issue for a couple of days. I’ll try a fresh Ubuntu install once more as it only takes a few moments.

Didn’t work. The same libOpenCL.so.1 error message appears on debug logs before and after running ‘apt install ocl-icd-libopencl1 beignet-opencl-icd’ on a completely fresh Ubuntu install.

Here you go, logs before and after installation of dependencies. attachments removed

Yessss it’s working! Thank you for being so patient, as you can see it’s my first week with Linux. I had no idea about that SNAP thing. Awesome :smile: [1]

Just wait. The pain will begin soon enough :smiling_imp:
