CPosPassThru::SetRate

  • Article

Sets a new playback rate.

HRESULT SetRate(
  double dRate 
);

Parameters

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

Return Values

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.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
