IMixerPinConfig::SetRelativePosition method (mpconfig.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetRelativePosition method sets the position of the stream in the display window.

Remarks
This method assumes window coordinates of {0, 0, 10,000, 10,000}. Therefore, if you want your video stream to be rendered in the bottom right quarter of the display window, you would call this method with the parameters {5,000, 5,000, 10,000, 10,000}.
