Which ppa for graphics acceleration on coolpi laptop (rk3588)?

enok71

I'm trying to explore hardware acceleration features on my rk3588 based laptop. I run Ubuntu 22.04 as installed when I received it.

Are there any package sources (ppas?) that I could add to make this work easily? Or do I have to recompile all the libraries myself from github repositories?

I found ffmpeg-rockchip and compiled rkrga, rkmpp and ffmpeg-rockchip yesterday trying to get an ffmpeg that uses r3588 hardware video encoder. But it fails to run. Do I need to recompile libdrm also? The kernel?

Thank you and best regards!

Ok the following command line actually seems to work with my own compiled ffmpeg-rockchip, based on my own compiled rkrga and rkmmp. And top shows zero cpu-load so the CPU is actually not used at all.

ffmpeg -i /dev/video0 -c h264_rkmpp /tmp/tmp.mp4

Still interersted in URL to some source of precompiled Ubuntu packages though. Thanks.

Answering myself once more ... there is a ppa here although I'm not sure that's the optimal one for rk3588?

If someone is more sure of the best place to look for hardware accelerated software packages please help.

@enok71 Just in case someone reads my postings in this thread: The best source for coolpi hardware support packages is probably Georges ppa. Probably best to avoid mixed in packages from Liu Jianfengs ppa.

@enok71
Due to copyright issues with ffmpeg, only limited decoding support has been provided for ffmpeg Rockchip.

@enok71
The hardware acceleration software package currently defaults to using George PPA. We are currently researching a new branch and will release the results as soon as possible.

@enok71
George ppa provides ffmpeg source code and its patches, and can continue to develop on this code. We hope to support more formats. Especially in the coding part.
