@zsbzsb: I think his suggestion was perfectly valid. A video player should exist for the same reasons that the audio module exists in my opinion. You say we should only suggest things that cannot be built on top of SFML, but then really what is SFML? It's not a multimedia library anymore. Since graphics, audio, networking are relatively independent, you can always just use another library and add on functionality. They are not so intertwined that you cannot have one without the other. SFML in my eyes is supposed to be a collection of easy to use interfaces to multimedia functionality, and video playback falls under this just like audio playback does.
So, I am for MW2TopTenWORLD's idea.
