1 How to test VPU
1.1 OS
Tested on the following OS:
1.1.1 Debian11 (bullseye)
- rk3588-sd-debian-bullseye-desktop-6.1-arm64-20240117.img.gz
- rk3568-sd-debian-bullseye-desktop-6.1-arm64-20231113.img.gz
1.1.2 Ubuntu20 (focal)
- rk3588-sd-ubuntu-focal-desktop-6.1-arm64-20240116.img.gz
1.1.3 Buildroot
- rk3588-sd-buildroot-5.10-arm64-20240117.img.gz
1.2 Check mpp version
mpp_info_test tail /var/log/messages
1.3 Test hardware video decoding
wget http://112.124.9.243/test/200frames_count.h264 -O 200frames_count.h264 mpi_dec_test -t 7 -i 200frames_count.h264 tail /var/log/messages
1.4 Test hardware video encoding
Encoding nv12 video streams to h264:
wget http://112.124.9.243/test/4k_nv12.yuv.gz -O 4k_nv12.yuv.gz gzip -d 4k_nv12.yuv.gz mpi_enc_test -w 3840 -h 2160 -t 7 -i 4k_nv12.yuv -f 0 -o 4k_nv12.h264 tail /var/log/messages
Packaged as playable mp4 file:
ffmpeg -i 4k_nv12.h264 -vcodec copy -f mp4 4k_nv12.mp4
Note: The above video stream file 4k_nv12.yuv was grabbed on the T6 via HDMI-In with the following command：
v4l2-ctl -d /dev/video0 --set-fmt-video=width=3840,height=2160,pixelformat='NV12' --stream-mmap=4 --stream-skip=10 --stream-to=/tmp/4k_nv12.yuv --stream-count=240 --stream-poll
1.5 Re-compile mpp on debian/ubuntu (optional)
On the target board:
sudo apt update
sudo apt install gcc g++ cmake make
cd ~
git clone https://github.com/friendlyarm/mpp
# Or git clone https://github.com/rockchip-linux/mpp.git
cd mpp/build/linux/aarch64/
sed -i 's/aarch64-linux-gnu-gcc/gcc/g' ./arm.linux.cross.cmake
sed -i 's/aarch64-linux-gnu-g++/g++/g' ./arm.linux.cross.cmake
./make-Makefiles.bash
make -j$(nproc)
sudo make install
cd test
sudo cp mpp_info_test /usr/local/bin/mpp_info_test
sudo cp mpi_dec_test /usr/local/bin/mpi_dec_test
sudo cp mpi_enc_test /usr/local/bin/mpi_enc_test1.6 Re-compile mpp on buildroot (optional)
On the Host PC:
export PATH=/path/to/your/buildroot-rk3588/buildroot/output/rockchip_rk3588/host/bin/:$PATH cd buildroot-rk3588/external/mpp/build/linux/aarch64 sed -i 's/aarch64-linux-gnu-gcc/aarch64-linux-gcc/g' ./arm.linux.cross.cmake sed -i 's/aarch64-linux-gnu-g++/aarch64-linux-g++/g' ./arm.linux.cross.cmake ./make-Makefiles.bash make -j$(nproc) cd test
Go to the mpp directory and copy librockchip_mpp.so.0 to the target board:
wget http://YourIP/files/mpp/librockchip_mpp.so.0 -O /usr/lib/librockchip_mpp.so.0
Go to the test directory and copy mpp_info_test,mpi_dec_test,mpi_enc_test to the target board:
wget http://YourIP/files/mpp/mpp_info_test -O /usr/bin/mpp_info_test wget http://YourIP/files/mpp/mpi_dec_test -O /usr/bin/mpi_dec_test wget http://YourIP/files/mpp/mpi_enc_test -O /usr/bin/mpi_enc_test
