The SetRate method sets the playback rate. This method implements the IMediaSeeking::SetRate method.
Syntax
HRESULT SetRate(
double dRate
);
Parameters
dRate
Playback rate.
Return Value
Returns an HRESULT value.
Remarks
This method updates the value of the CSourceSeeking::m_dRateSeeking member variable, and then calls the pure virtual method CSourceSeeking::ChangeRate. The method does not validate the dRate parameter.
