CBaseStreamControl.StopAt method

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 StopAt method informs the pin when to stop delivering data. This method implements the IAMStreamControl::StopAt method.

Syntax

HRESULT StopAt(
   const REFERENCE_TIME *ptStop = NULL,
         BOOL           bSendExtra = FALSE,
         DWORD          dwCookie = 0
);

Parameters
