Do not use the outdated MPP libs from Radxa.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Sadly this doesn't prevent people from still trying to use outdated libraries because Rockchip never bumps version numbers in pkgconfig/rockchip_mpp.pc.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.

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.
