Delphi10.4.1 ios13.7 FmxTestApp not working #109

Hi, on click on "Start Camera" Button on a iPad the app crash with a execption. ECaptureDeviceException.

But i think this is a problem from the TCameraComponent.

Maybe you can check this please?

Unit FMX.Media.AVFoundation ` procedure TAVVideoCaptureDevice.RecordingRequestAccessForMediaTypeCompletionHandler(granted: Boolean); var LMessage: string; begin if granted then LMessage := string.Empty else LMessage := SUserRejectedCaptureDevicePermission;

TThread.Synchronize(nil, procedure begin DoPermissionRequest(LMessage, granted); ----> exception here end); end; `

The code above looks fine to me.

But the fmx camera is not the best camera. It does not perform very well. If you need scanning and IOS only then you better off with scanning natively because scanning is build into IOS camera. Look at WinSoft.sk

Anyway, I uploaded an improvement of the fmxTestApp. Maybe it will help.
