I have installed desktop version V190830 image on VIM3.
According to NPU Demo and source code and Simple NPU demo on VIM3 Ubuntu Bionic, I got correct result of inceptionv3:
root@Khadas:~/aml_npu_demo_binaries/inceptionv3/VIM3# ./run.sh

When I test Yolov3, there is an error:
root@Khadas:~/aml_npu_demo_binaries/detect_demo_picture# ./detect_demo_fb 0 1080p.bmp
./detect_demo_fb: error while loading shared libraries: libavcodec.so.58: cannot open shared object file: No such file or directory
This is the info of ldd:

I can find libavcodec.so.57 and libavcodec.so.53 on vim3:
root@Khadas:~/aml_npu_demo_binaries/detect_demo_picture# locate avcodec
/usr/lib/libavcodec.so
/usr/lib/libavcodec.so.53
/usr/lib/libavcodec.so.53.7.0
/usr/lib/aarch64-linux-gnu/libavcodec.so.57
/usr/lib/aarch64-linux-gnu/libavcodec.so.57.107.100
How to solve the problem? Do I need to flash a newer image?
