Hello,I can not do this “sudo apt-get install -y libavformat-dev libavutil-dev libavcodec-dev libswscale-dev libfreetype6-dev”.No package ... available, so could you guide me in the issue?
Thank u!!!

The idea is that you need to install libav or ffmepg. The exact command can vary depending on your OS and its version.
