IFullScreenVideoEx::IsKeepPixelAspectRatio method (amvideo.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 IsKeepPixelAspectRatio method queries whether the pixel aspect ratio is maintained. The Full Screen Renderer filter does not support this method; it always maintains the pixel aspect ratio.
