3/26/2014

Override this member function to handle notification of a change of start time.

Syntax

virtual HRESULT ChangeStart( ) PURE;

Parameters

None.

Return Value

Returns an HRESULT value that depends on the implementation. HRESULT can be one of the following standard constants, or other values not listed.

Invalid argument.

Remarks

This member function is called when a new start position has been requested by a call to CSourceSeeking::SetPositions.

Override this and change the data sent.

Typically, you do this by calling CBaseInputPin::BeginFlush and CBaseInputPin::EndFlush, and then send samples marked with new start time (for example, with an implementation NewSegment method).
