ffmpeg for Ubuntu

I looked for ffmpeg to run on my Ubuntu VirtualBox VM. However, it turned out that there is a competitor (fork of ffmpeg) which is typically used with Ubuntu: libav.

So the install was very easy:

sudo apt-get update
sudo apt-get install libav-tools

and avprobe prints info about the video file -
