Sets a new playback rate.
HRESULT SetRate( double dRate );
Parameters
- dRate
- New rate, where 1.0 is the normal normal playback speed.
Specifying 2.0 causes playback at twice the normal rate: a video
created for 10 frames per second (fps) will be played back at 20
fps, if resources permit. Audio streams played back at above-normal
speed increase the pitch rather than drop samples. A rate of 0.5
specifies half speed.
Return Values
Returns the HRESULTvalue returned by the call to the CSourceSeeking::ChangeRatefunction.
Remarks
You must implement ChangeRateto use this method. The m_dRateSeekingdata member is set to the new rate. Setting the rate to zero causes an error.
