Batch mode won't run in headless environment.

I tried running batch mode while ssh'ed into a virtual machine, and got the following error:

$ soundconverter -b -m "audio/mpeg" -s ".mp3" *.flac
soundConverter 2.9.0-beta1

However, running on the exact same virtual machine in a local terminal (so from the VM's desktop) the command runs fine.

A work around is to install and use a virtual frame buffer. Instructions below with others who have the same requirement:

1) Install xvfb (X Virtual Frame Buffer)

sudo apt-get install xvfb

2) Start a virtual frame buffer and switch your terminal onto it. Note the capitalization of Xvfb below, that's not a typo.

Xvfb :99 &
export DISPLAY=:99

3) Run your batch soundconverter command:

soundconverter -b -m "audio/mpeg" -s ".mp3" *.flac
