[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetSourcePosition method sets the source rectangle.

Syntax

HRESULT SetSourcePosition(
  [in] long Left,
  [in] long Top,
  [in] long Width,
  [in] long Height
);

Parameters

[in] Left

Specifies the x-coordinate, in pixels.

[in] Top

Specifies the y-coordinate, in pixels.

[in] Width

Specifies the width, in pixels.

[in] Height

Specifies the height, in pixels.

Return value

Returns an HRESULT value.

Remarks

This method has the same effect as individually calling the IBasicVideo::put_SourceLeft, IBasicVideo::put_SourceTop, IBasicVideo::put_SourceWidth, and IBasicVideo::put_SourceHeight methods.

Setting this coordinate does not affect the destination rectangle height.
