Comment 18 for bug 1051559

Looks like simple usages of GStreamer shouldn't be broken (but http://cgit.freedesktop.org/gstreamer/gstreamer/tree/docs/random/porting-to-1.0.txt is pretty long...).
Maybe we can load GStreamer dynamically and, if we use only a subset of the API, we could avoid running into issues (just like we're now doing with libnotify).
AFAIK, there will be other API breakages in the future.
