Return Values

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.
