Webcam input comes up mirrored in Unreal Engine 5.6

I’m trying to display a live webcam feed inside my Unreal project using a Media Texture, but the image comes in mirrored. When I use Live Link with a MetaHuman, the character’s head movements also is inverted compared to my own (e.g. when I turn my head right it turns left and vice versa). Is there a way to un-mirror the webcam input (either via Media Player/Material settings or another option) so that both the video feed and Live Link tracking match my real-world orientation?

p.s. In other apps the webcam feed is not mirrored.
