Remarks

Horizontal mirroring is useful for video conferencing or video chat applications, because the users typically want to see a reflected image of themselves. The non-mirrored view can look strange, because we are used to seeing ourselves in a mirror.

To mirror the preview video, apps should instead use the following method. Windows app using JavaScript should use the msHorizontalMirror property of the video object. UWP apps using C++, C#, or Visual Basic should use the FlowDirection property on the CaptureElement.

SetPreviewMirroring can potentially be used as a performance optimization on some devices
