Attempting hardware acceleration, ffmpeg -init_hw_device says "No device found"

[guiniveretoo]

I have all these lovely movies and shows that are 10-bit and the poor cpu just can't keep up with them, they stutter and jitter, on the computer, on my phone, on the TV (via Roku).

Ubuntu 22.04.2 LTS, Jellyfin 10.8.10, ffmpeg version 5.1.3-Jellyfin

We recently installed a Radeon 270, hoping that it would help. I'm not sure it was installed correctly, I'd love help diagnosing that if it's relevant. I'm trying to go through the steps here: https://jellyfin.org/docs/general/admini...ration/amd

I'm stuck on step 6:

Code:

    $ sudo /usr/lib/jellyfin-ffmpeg/ffmpeg -v debug -init_hw_device opencl=ocl:.0,device_vendor="Advanced Micro Devices"

I believe I have the correct drivers installed:

Code:

$ lspci -k | grep -EA3 'VGA|3D|Display'
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Curacao XT / Trinidad XT [Radeon R7 370 / R9 270X/370X]

        Kernel driver in use: amdgpu
        Kernel modules: radeon, amdgpu

rocm-opencl-runtime is installed and up-to-date, but clinfo gives no devices found:

Code:

$ sudo clinfo

Am I doing anything wrong? Do I just need to suck it up and upgrade my hardware more or is something set up incorrectly?
