CBaseStreamControl.Flushing method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The Flushing method notifies the base class that the pin has started or stopped flushing.
Syntax
void Flushing(
BOOL bInProgress
);
Parameters
-
bInProgress
-
Specifies a Boolean value that indicates whether the pin is flushing. Use the value TRUE when the pin begins a flush operation, and FALSE when the pin ends a flush operation.
Return value
This method does not return a value.
Remarks
The pin must call this method from within its IPin::BeginFlush and IPin::EndFlush methods. Specify TRUE in BeginFlush and FALSE in EndFlush.
This method causes the CBaseStreamControl::CheckStreamState method to stop waiting. While the pin is flushing, CheckStreamState always returns STREAM_DISCARDING.
