You can't really opensource a project if it includes, say, a movie playback component or 3d engine or audio code with royalty-based licencing; the code won't even compile with it, and it may be customized/integrated to an extent where it would be a lot of work to even identify which of your source code files are "contaminated" by licenced stuff that isn't yours to publish.
