That will be the ideal, but that include file is not included in package libgstreamer-plugins-bad1.0-dev. So we would need to do that in plugins-bad, and also include it as build dependency in media-hub. Not saying that we should not do it, but I do not know if it is worth the effort atm. Note also that we are using g_object_set with literal strings all around in this file (and previously g_object_set(..., "surface",...)).
