ICM_DRAW_RENDERBUFFER message

The ICM_DRAW_RENDERBUFFER message notifies a rendering driver to draw the frames that have been passed to it. You can send this message explicitly or by using the ICDrawRenderBuffer macro.

wParam = 0; 
lParam = 0; 

Return Value

This message does not return a value.

Remarks

Use this message with hardware that performs its own asynchronous decompression, timing, and drawing.

This message is typically used to perform a seek operation when the driver must be specifically instructed to display each video frame passed to it rather than playing a sequence of video frames.
