Steps to reproduce according to samples/configs/deepstream-app-triton/README:

2. apt update && apt install ffmpeg

3. Run the video preparation script:

Do you have any ideas, what can go wrong?

it is ffmepg installing issue, you can find the path of libavformat.so, then add it to LD_LIBRARY_PATH, here is a sample:
$ find / -name “libavformat.so*”
/home/test/test/libavformat.so.58.29.100
$ export LD_LIBRARY_PATH=/home/test/test/:$LD_LIBRARY_PATH && ldconfig

I don’t know why this happens in this image, but reinstalling these packages helped:

apt install libavformat58 --reinstall
apt install libavcodec58 --reinstall
apt install libavresample4 --reinstall
apt install libavutil56 --reinstall
