Issues with HW transcoding - RK3588

[hedefalk]

I'm having the same issue.

I'm also running jellyfin on a FriendlyElec CM3588 Plus with the NAS SDK (32 GB RAM)

I'm running on a k3s cluster, but I've mapped the devices I think are needed (not mali0 though, but I have deselected tone mapping:



root@jellyfin-5d8cbd85c9-9btsr# ls -l /dev | grep -E "mpp|rga|dri|dma_heap"
drwxr-xr-x 2 root root        160 Jan  1  1970 dma_heap
drwxr-xr-x 3 root root        140 Jan 26  2024 dri
crw------- 1 root root    241,  0 Jan 26  2024 mpp_service
crw------- 1 root root    10, 122 Jan 26  2024 rga


I guess most relevant thing here is what got me to find this thread:

>Failed to set value 'opencl=ocl@rk' for option 'init_hw_device': No such device

In the jellyfin main logs I see:


MediaBrowser.Common.FfmpegException: FFmpeg exited with code 187

and in the ffmpegtranscode logs I have:


[hevc_rkmpp @ 0x558e173500] Failed to init MPP context: -1

On my host I'm only seeing a subset of the devices listed in the docs, but this exact subset is mentioned here too:

root@CM3588-Plus:~# for dev in dri dma_heap mali0 rga mpp_service \
iep mpp-service vpu_service vpu-service \
hevc_service hevc-service rkvdec rkvenc vepu h265e ; do \
[ -e "/dev/$dev" ] && echo " --device /dev/$dev"; \
done
--device /dev/dri
--device /dev/dma_heap
--device /dev/mali0
--device /dev/rga
--device /dev/mpp_service

Are these other devices needed too?
