[FREQ] Make live image view on camera screen is same as actual output image

[tiendq]

Context

I want to capture 4:3 scale image and I use below code, captured image is exact what I wanted (4:3) but camera screen (MCameraScreen) always shows live image in full screen mode (which is 16:9 scale on my iPhone 11, I guess).

For short, I want it works same as built-in Camera app, (live) camera screen shows exact image in chosen scale (4:3 or 16:9).

MCamera()
        .setCameraOutputType(.photo)
        .setResolution(.photo)
        .startSession()

Alternatives

No.
