Do not use the outdated MPP libs from Radxa.
from ffmpeg-rockchip.
Sadly this doesn't prevent people from still trying to use outdated libraries because Rockchip never bumps version numbers in pkgconfig/rockchip_mpp.pc. The version checking during the configure
stage of FFmpeg could have fundamentally avoided this problem, but Rockchip's approach makes this impossible.
Since I am not an employee of Rockchip, please report such issues to upstream and urge them to resolve them. Thanks.

I will use that in a future FFmpeg version. But for now it's too new for most distros and people will complain about this;)

ffmpeg was running under root and it had access to the devices.

Extremely humble opinion: it might make sense to put this requirement (which exactly version is required) somewhere. For example:
- Here: https://github.com/nyanmisaka/ffmpeg-rockchip?tab=readme-ov-file#important
- And here: https://github.com/nyanmisaka/ffmpeg-rockchip/wiki/Compilation
If somebody can tell which exactly minimum version is required then I can prepare a PR for README.md.
