This method has no parameters.
This method returns one of the following values:
The plug-in has successfully flushed queued data and is ready to accept new samples.
This method should not return an error code while samples are still referenced.
This method should reset the plug-in so that it is ready to accept samples after this call completes. This method should signal all the pended samples that were supplied by using IKsVideoProcessing::ProcessInput and IKsVideoProcessing::ProcessOutput.
Calling this method does not invalidate the selected media types of the plug-in's input and output.
