CameraView and device orientation

[RcBrgr]

I have played around a bit with CameraView and also captured images in landscape orientation but the images are rotated. Do I need to make some configuration like changing the resolution or other configuration?

What platform are you seeing this on?

[RcBrgr]

Android - Samsung A33 5G - SDK 34

Thanks. @jfversluis i recall there was an issue in the XCT around rotation issues and you applied a fix for it. Do you recall what it was?

[jfversluis]

Looking at the issues and PRs there we tried but never 100% fixed it

[RcBrgr]

Thanks for the clarification. Since the CameraView is now using CameraX for Android, I might give it a try implementing. Android has a promising documentation: https://developer.android.com/media/camera/camerax/orientation-rotation

Good find! Let us know how that goes

@bijington @jfversluis I'm also experiencing this on iOS 17.5.1. Do you know of any workarounds I could use?

[bijington]

I suspect what you might be seeing on iOS is a result of there being more than 4 orientations for an iOS device https://developer.apple.com/documentation/uikit/uideviceorientation. I have seen in the past that even the iOS camera app can fail to get the photo orientation exactly correct when the device is close to faceUp or faceDown. I am not aware of anything that can be done immediately, I think in the past I have monitored the last used good orientation (excluding faceUp and faceDown) and used that as a best guess.

I have a solution implemented for iOS and Android, needs a bit more testing but it is promising. I need to wait currently for approval of the CLA from my employer, then I will open a PR.

@bijington I'm probably experiencing that too, but even before that, if I take a picture in any orientation other than portrait the pictures will be rotated. Thank you for the Apple docs link, I'll see if I can get that to work.

When you get the orientation info, what do you do to apply it? Rotate the image data itself? Add an EXIF tag?

@RcBrgr Have they responded yet?
