Steps to Reproduce

Confirmed on Pixel 3a XL Android 12 and Xiaomi Redmi 3s Android 6.0.

1. Open the attached project and run.

2. Press the Capture button which invokes the Shutter() method:

1. The app saves the captured image data into a new file and sets that file as a source of the ImageView (right below the camera view):

Expected Behavior

ImageData of MediaCapturedEventArgs contains a JPEG image with correct orientation applied.

Actual Behavior

ImageData is an incorrectly rotated JPEG and additional manual transformations are required.

Basic Information

• Version with issue: 1.3.0-pre2
• Last known good version: None
• IDE:
• Platform Target Frameworks:
  • iOS:
  • Android:
  • UWP:
• Android Support Library Version:
• Nuget Packages:
• Affected Devices: Pixel 3a XL (Android 12), Xiaomi Redmi 3s (Android 6)

Workaround

A workaround is to use ImageSharp where you can manually rotate the image according to MediaCapturedEventArgs.Rotation property. It works pathetically slow though.

public static class MediaCapturedEventArgsExtensions
{
    public static byte[] GetRotatedData(this MediaCapturedEventArgs self)
        => TransformOrientation(self.ImageData, self.Rotation);

    private static byte[] TransformOrientation(byte[] imageInBytes, double rotation)
    {
        using var image = Image.Load(imageInBytes, out IImageFormat imageFormat);
        RotateMode mode = rotation switch
        {
            90d => RotateMode.Rotate90,
            180d => RotateMode.Rotate180,
            270d => RotateMode.Rotate270,
            _ => RotateMode.None,
        };
        image.Mutate(x => x.Rotate(mode));
        return ImageToByteArray(image, imageFormat);
    }

    private static byte[] ImageToByteArray(Image image, IImageFormat imageFormat)
    {
        using var ms = new MemoryStream();
        image.Save(ms, imageFormat);
        return ms.ToArray();
    }
}
