Rock64 hardware video acceleration

[fenouil-r]

Hello,

I have been using your OMV5 release for a long time now and very happy with it !
Recently, I have been trying to get Frigate running, but the board struggles with multiple h264 encoding and decoding simultaneously.

Good news is that rk3328 has hardware h264 encoding/decoding support, but I cannot get it to work.
It looks like a kernel based on BSP is required to access it (unless available from mainline too ?).

I got support after opening issues in Frigate and ffmpeg repositories, and a post on LibreElec forum here.

However I'm not sure to understand how to get a proper kernel to make ffmpeg happy :)

When using apt package manager from your release, I have a lot of options for available kernels, some named 'ayufan', others not.
However, it seems rockchip BSP kernels are versions 5.10, 6.1 or 6.10, but none of them is listed by package manager.

Regarding 'Ayufan' kernel releases, I don't see any 5.x or more recent on this repository, although I see some in apt list... Is this normal ?

Can you help me to understand where to find proper kernel, and tell me whether your work is based on rockchip BSP kernels ?

I see LibreElec provides distributions with 5.10, 6.1 or 6.10 kernels, but no success there too.
Also I saw rockchip is supposed to only support rk3328 up to kernel 5.10.

As you see, I'm a bit lost with all these kernels versions, sources, and features....
Any help would be appreciated :)

All information about tests/logs and different kernels in linked issues above, feel free to comment there if you prefer.

Thank you !
