MPP is not working on RK3566 platform

[gilmotta3]

Hello friends,

I cloned the latest MPP repo and built it according the following instructions:

git clone https://github.com/rockchip-linux/mpp
pushd mpp
cmake -DRKPLATFORM=ON -DHAVE_DRM=ON && make -j$(nproc)
sudo make install
sudo cp ./mpp/librockchip_mpp.so* /lib/aarch64-linux-gnu
sudo cp ./mpp/legacy/librockchip_vpu.so* /lib/aarch64-linux-gnu
popd

then I built FFmpeg accoding the following instructions:

git clone https://github.com/hbiyik/FFmpeg.git
pushd FFmpeg/
./configure --enable-rkmpp --enable-version3 --enable-libdrm --enable-libx264 --enable-gpl
make -j$(nproc)
sudo make install
popd

However FFmpeg is not able to initialize MPP and it is throwing an error!

and from the log I only see one line which I have no clue!

Can anyone please assist me with this? My goal is to run hardware encoding on the RK3566. I would l like to use ffmpeg and gstreamer on the RK3566 to encode the video input.

Thank you!
