[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetSyncSource method is called when a new clock is registered.

Syntax

HRESULT SetSyncSource(
  [in] IReferenceClock *pClock
);

Parameters

[in] pClock

Pointer to the new clock's IReferenceClock interface.

Return value

Returns an HRESULT value.

Remarks

This method is called before the filters are notified. Make sure to use AddRef on the pClock parameter if the plug-in distributor intends to hold it beyond this method call.
