Why is my rear facing camera mirroring images when I record video?

[Android Central Question]

When I record, everything looks fine. When I review the video, the video is mirrored or flipped. I see how to correct this issue for the front facing camera when taking pictures. Nothing for how to correct this issue for video. Need this to work correctly for upcoming online classes and I can't find a fix.
