BUG - Setting facingMode on video inputSetting has no effect

[MerlinB]

Expected behavior

Passing

inputSettings: {
    video: {
        settings: {
            facingMode: "environment",
        },
    },
},

into Daily.createFrame I'd expect the video to no longer be mirrored. (See https://developer.mozilla.org/en-US/docs/Web/API/MediaTrackConstraints/facingMode for mdn docs)

Describe the bug (unexpected behavior)

Within the Iframe, the video element still has data-mirrored=true set and the transform: scale(-1, 1); CSS property applied and is thus still mirrored.

facingMode, as you point out, is an underlying track constraint that browsers support. However, it does not affect whether the video is flipped or not. Rather, it is a generic way to tell the browser which device you want to get. Specifically, this is primarily used on mobile to tell the browser whether to use the selfie cam ("user") or the outward-facing cam ("environment"). On a desktop, with a built-in camera or a camera plugged in, facingMode typically can only be "user" and setting it to something else has no effect.

Based on your issue, I assume you are using our prebuilt offering. Unfortunately, we do not have a way to override the mirroring behavior at this time.
