	Stereoscopic, or 3D, video support was implemented into the VLC Media Player as part of my Google Summer of Code project. It is currently experimental with a couple of bugs and I'm still actively working on it. At present you must build it from source, and I'm looking to soon merge it into the main tree.

			The default value for i_eye is 0, and all present video codecs output frames where i_eye is 0. It is up to the stereoscopy module to split it into left and right. But it's possible for someone to develop a video codec that output pictures where i_eye>0, for example for a container format where the data is stored as separate left/right images. In this case the stereoscopy module does nothing, and forwards the pictures on as is.

			Mask i_eye by STEREO_EYE_MASK to get the eye number without any flags. It is possible that two images represent the same point in time (this is only untrue for field sequential video). If the STEREO_WAIT_FOR_NEXT_FRAME_BIT is set then the vout shouldn't present the frame straight away, but expect another picture immediately joining it representing the other eye at the same point of time, and display them together at once.
