[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 QueryPinInfo method retrieves information about the pin.

HRESULT QueryPinInfo(
  [out] PIN_INFO *pInfo
);

Return code	Description

Remarks

When the method returns, if the pFilter member of the PIN_INFO structure is non-NULL, it has an outstanding reference count. Be sure to release the interface when you are done.
