Description	Special applications are developed in the area of virtual reality, multimedia communications and others where combinations of audio, video, 3D data are sent between two (or more) distant users which can interact with these data. A form of so exchanged information usually requires, among others, special forms of presentation. Thus stereoscopic and virtual reality visualization devices are used to present intricately structured information. There are situations where the presented information is to be rendered in real-time and transmitted to the remote user. In this case, the content is presented on a local visualization device (e.g. CAVE) being simultaneously sent to a remote device. The problem is, how to obtain the rendered data for transmission with minimal impact on the rendering and visualization process. In this paper, we present a method how to retrieve video stream from an arbitrary running OpenGL application, capturing every frame with minimal impact on performance.
