CSourceSeeking::ChangeRate
Override this member function to handle notification of a change of sample rate.
virtual HRESULT ChangeRate( ) 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 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.
