IVPConfig::SetScalingFactors method (vpconfig.h)

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetScalingFactors method sets the factors by which the decoder should scale the video stream.

  [in] LPAMVPSIZE pamvpSize
);

Parameters

Pointer to the new scaling size structure (AMVPSIZE) to use to specify the width and height.
