Preview flattened when in container

[jeryRazakarison]

Hi,

I would like to put the BarcodeScannerController inside a ContainerView (in order to have the Barcode scanner on the top half of the screen, and a tableview with the list of scanned barcode on the bottom half of the screen).

But when I tries to embed the BarcodeScannerController in a container which sizes the half of the height of the screen, the preview is flattened. Do anyone have an idea of how to fix it?

Thank you a lot,

Jery

This would be due line 179 in the controller: videoPreviewLayer?.videoGravity = AVLayerVideoGravityResize;

It should be: videoPreviewLayer?.videoGravity = AVLayerVideoGravityResizeAspectFill;

Oh, yes! Thank you for pointing this. Do you intend to do a PR, or do you want me to do it?
