#1

I have download armbian sid for rockpi 4p+ in https://github.com/armbian/community
I have compile mpp, but mpp_platform_test print H.264 decoder: (null), and I can’t use mpp in ffmpeg
I also can’t find /dev/mpp_service

This is how I compile mpp.

 git clone -b release https://github.com/rockchip-linux/mpp.git 
 cmake -DRKPLATFORM=ON -DHAVE_DRM=ON && make -j5
 make install

Proprietary rockchip video platform will not work on mainline based kernel.

  • move to most recent kernel
  • check / switch to armbian forums
  • you are looking for Hantro video codecs support
