fixed : sudo apt install libavdevice-dev

[anshulrouthu]

In order to prevent this kind of system dependency on libav* libraries, setup.sh will build the ffmpeg library locally from with in the repository and installs in (root)/staging directory. If you had successfully run the setup.sh script you wouldn't need to install the libavdevice-dev on your system. I will fix the setup.sh script to error out if the setup was not successful, that was bad on my part.
