The old versions of ffmpeg libraries are not available on for Ubuntu20 #60

There are several libraries as:
libavformat-ffmpeg.so.56 => not found
libavutil-ffmpeg.so.54 => not found
libswscale-ffmpeg.so.3 => not found
libavdevice-ffmpeg.so.56 => not found

which are not available on Ubuntu 20 after installing the Pangolin recommended ffmpeg dependency. Is there any workaround to change these libraries for Cilantro's example applications?
