IVMRWindowlessControl9::SetBorderColor method (vmr9.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetBorderColor method sets the border color to be used by the VMR.

Syntax

HRESULT SetBorderColor(
  [in] COLORREF Clr
);

Parameters

[in] Clr

Specifies the color as a COLORREF value.

Return value

The method returns an HRESULT. Possible values include those in the following table.

Remarks

The border color is used to fill any area of the destination rectangle that does not contain video. It is typically used in two situations:

• When the video straddles two monitors
• When the VMR is trying to maintain the aspect ratio of the movies by letter-boxing the video to fit within the specified destination rectangle. See SetAspectRatioMode.
