CSourceSeeking.SetRate method

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

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.
