CBaseInputPin.BreakConnect 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 BreakConnect method releases the pin from a connection.
Syntax
HRESULT BreakConnect();
Parameters
This method has no parameters.
Return value
Returns S_OK if successful, or an HRESULT value indicating the cause of the error.
Remarks
This method overrides the CBasePin::BreakConnect method. It decommits the allocator and releases the IMemAllocator interface.
If you override this method, call the base-class method from your overriding method. Otherwise, you might cause memory leaks.
