hardware-acceleration rockchip/

[sigma]

I have tried to get the hardware acceleration get working, but I also get some error from ffmpeg:
[h264_rkmpp @ 0xaaaac639cab0] Failed to init MPP context: -1

Current setup:

• orangepi5 rk3588
  
• dietpi 9.4
  
• Linux version 5.10.160-legacy-rk35xx (armbian@next) (aarch64-linux-gnu-gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0, GNU ld (GNU Binutils for Ubuntu) 2.38 ) #1 SMP Fri Feb 2 07:51:33 UTC 2024
  
• official docker container from jellyfin 10.9.2
  
• docker command from the jellyfin doc pages [docker command]
  
• installed libmali (sudo apt install ./libmali-valhall-g610-g13p0-gbm_1.9-1_arm64.deb)
  

check the files in the device folder (dma_heap, mali0, mpp_service, rga exist and accessible in the docker container)
check the opencl out put in the docker container and looks good (see attached file)

So in my opion everything looks good, but it crashed with different ffmpeg errors showing in the logs.

Have I something forgot or some advice what could be wrong?
Thanks and regards
