I watch a live streamer on TikTok who films using an iphone's back camera, and his streams are always flipped horizontally. Is this done automatically by TikTok? Or does the iphone do it? (I read that iphone's front camera flips the screen to be like a mirror, but the back camera doesn't).

Is it possible that he flips it himself? I ask because he un-flips the video every now and then when he wants to show text to viewers, so he knows the stream is flipped. Whether he flipped it purposely or not, I don't know.

I can't ask him because he gets tens or hundreds of thousands of comments per stream, and I don't think his email is available (nor do I think he has time to read viewer mails).
