CSourceSeeking::ChangeStart

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

virtual HRESULT ChangeStart( ) PURE;

Return Values

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

E_FAIL	Failure.
E_POINTER	Null pointer argument.
E_INVALIDARG	Invalid argument.
E_NOTIMPL	Method isn't supported.
S_OK or NOERROR	Success.

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.
