  • [アーティクル]

Sets a new playback rate.

Syntax

HRESULT SetRate(
  double dRate 
);

Parameters

  • dRate
    New rate, where 1 is the normal rate, 2 is twice as fast, and so on.

Return Value

Returns E_INVALIDARG if dRate is zero. Otherwise, returns the HRESULT value returned from calling IMediaSeeking::SetRate on the connected pin.

Remarks

This member function implements the IMediaSeeking::SetRate method by calling this same method on the upstream filter's output pin. It is an error to set the rate to 0.
