CBaseFilter.ReconnectPin 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 ReconnectPin method breaks an existing pin connection and reconnects it to the same pin, using a specified media type.

Syntax

HRESULT ReconnectPin(
   IPin                *pPin,
   AM_MEDIA_TYPE const *pmt
);

Parameters

pPin

Pointer to the pin's IPin interface.

pmt
