TDX_DRAWVIDEOPORT
[ component ]
The TDx_DrawVideoPort component wraps the DirectX IDirectDrawVideoPort interface, which channels live video from the video port hardware to a surface, often an overlay, for display. It is used to start and stop the flow of video information, retrieve the input and output formats supported, retrieve the zoom factors required to display video successfully, change the video transfer parameters and retrieve the number of the video line currently being written to the frame buffer. Other methods include the retrieval of status, polarity or color control information, assigning target surfaces for the video, changing the flipping behavior, setting color controls and waiting for the vsync or a specified scan line.
