ofxVLC

It's an addon that wraps vlc as a video player for oF, extending ofVideoPlayer so it can be used wherever you are using the usual ofVideoPlayer.
It should be able not only to play video files but also to access video devices like dvb, v4l2, dv cameras...
Also it can open and create streams just by giving some options in the loadMovie method.
And some more options like cropping the input, applying filters...
