IMFPMediaPlayer::SetBorderColor method (mfplay.h)

Article
12/05/2018

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 It has been superseded by MediaPlayer and IMFMediaEngine.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

Sets the color for the video border. The border color is used to letterbox the video.

Syntax

HRESULT SetBorderColor(
  [in] COLORREF Clr
);

Parameters

[in] Clr

Specifies the border color as a COLORREF value. Use the RGB macro to create this value. The default value is black.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
MF_E_INVALIDREQUEST	The current media item does not contain video.
MF_E_SHUTDOWN	The object's Shutdown method was called.

Remarks

This method fails if no media item is currently set, or if the current media item does not contain video.

To set the border color before playback starts, call this method inside your event handler for the MFP_EVENT_TYPE_MEDIAITEM_SET event. For more information, see IMFPMediaPlayerCallback::OnMediaPlayerEvent.
