CSourceSeeking::ChangeRate
Override this member function to handle notification of a change of sample rate.
virtual HRESULT ChangeRate( ) 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 change to the rate has been made by a call to the CSourceSeeking::SetRate function. Override this and change the rate of data sent. Typically, you do this by calling CBaseInputPin::BeginFlush and CBaseInputPin::EndFlush, and then send samples marked with new time stamps, for example, with an implementation NewSegment method.
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.
