IGraphConfigCallback::Reconfigure 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 Reconfigure method is a callback method passed to IGraphConfig::Reconfigure.
Syntax
HRESULT Reconfigure(
PVOID pvContext,
DWORD dwFlags
);
Parameters
pvContext
Value passed in the IGraphConfig::Reconfigure method's pvContext parameter.
dwFlags
Value passed in the IGraphConfig::Reconfigure method's dwFlags parameter.
Return value
Returns S_OK if successful. Otherwise, returns an HRESULT value indicating the cause of the error.
Remarks
If your application or filter calls IGraphConfig::Reconfigure, you must implement this method and pass it as a callback. The IGraphConfig::Reconfigure method obtains a lock on the filter graph before calling your Reconfigure method. Your method then handles all the other details of dynamic graph building.
If this method succeeds, IGraphConfig::Reconfigure tries to put all the filters in the graph back into a running state. If the method fails, IGraphConfig::Reconfigure returns whatever error code this method returned.
This method allows for specialized graph rebuilding. For a more straightforward approach to dynamic graph building, see IGraphConfig::Reconnect.
