Code review comment for lp:~sil2100/cupstream2distro-config/stack_package_dependency_additions

Looking mostly good, thanks for the hard work Lukasz!

However, we need a way to remove gstreamer0.10-ffmpeg from the list of dependency. It's not in main but universe and the license of ffmepg makes it incompatible for us to ship it by default in the future. Is there any way to (even if we support less videos format for now on), plug anything gstreamer codec? (the -good ones we are installing by default for instance?)
