CSourceSeeking::ChangeStart (Windows CE 5.0)
Override this member function to handle notification of a change of start time.
virtual HRESULT ChangeStart( ) PURE;
Parameters
None.
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.
| Value | Description |
|---|---|
| E_FAIL | Failure. |
| E_POINTER | Null pointer argument. |
| E_INVALIDARG | Invalid argument. |
| E_NOTIMPL | Method is not 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).
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements.
For more information, see Setting Up the Build Environment.
OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
