>The ffmpeg implementation requires DRM. Make sure that mpp is built with -DHAVE_DRM and that your user can access the DRM devices (/dev/dri/?).

Mpp is built with -DHAVE_DRM.
You are right, my user cannot access the DRM device.

But i started my decoder program with sudo access and this does not help, but the output is changed.

New output:
