CPosPassThru.ForceRefresh 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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The ForceRefresh method is obsolete.
Syntax
HRESULT ForceRefresh();
Parameters
This method has no parameters.
Return value
Returns S_OK.
Remarks
Originally this class was designed to cache pointers to the connected pin's IMediaPosition and IMediaSeeking interfaces. The ForceRefresh method released those interfaces.
As currently implemented, this class does not cache those interfaces. For compatibility, the ForceRefresh method is still included, but it returns S_OK without doing anything.
