IPinConnection::DynamicDisconnect method (strmif.h)
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 DynamicDisconnect method disconnects the pin when the filter is active (paused or running). Call this method instead of IPin::Disconnect to disconnect a pin when the graph is running or paused.
The caller must ensure that no data is flowing to the pin when it calls this method. Call the IPinFlowControl::Block method on an upstream pin to block the data flow, or use some other mechanism to make sure that no samples are delivered until this pin is reconnected.
