This paper studies and implements a 3D video player, which can play multiple video at the same time. To expand the application space of multimedia technology, making it closer the engineering applications. Combined with Multimedia Technology and OpenGL technology, designed a 3D video player. It can play a different video in different surface of three-dimensional graphics, and play several different video in multiple 2D planes at the same time. 2D graphics and 3D graphics can be flexible and comfortable in the deformation, moving, rotating, etc. Experimental results show that play picture is smooth and natural. We can freely choose the number of the video. There is no disturbed between various video, reach a more ideal and satisfactory playback effect.
