The camera customization UI is upside down #101878
Description
I saw when send command device left and iOS execute device right, like this:
if ([orientation isEqualToString:@"portraitDown"]) {
return UIDeviceOrientationPortraitUpsideDown;
} else if ([orientation isEqualToString:@"landscapeLeft"]) {
return UIDeviceOrientationLandscapeRight;
} else if ([orientation isEqualToString:@"landscapeRight"]) {
return UIDeviceOrientationLandscapeLeft;
} else if ([orientation isEqualToString:@"portraitUp"]) {
return UIDeviceOrientationPortrait;
}
but why
if (deviceOrientation == UIDeviceOrientationPortrait) {
return AVCaptureVideoOrientationPortrait;
} else if (deviceOrientation == UIDeviceOrientationLandscapeLeft) {
// Note: device orientation is flipped compared to video orientation. When UIDeviceOrientation
// is landscape left the video orientation should be landscape right.
return AVCaptureVideoOrientationLandscapeRight;
} else if (deviceOrientation == UIDeviceOrientationLandscapeRight) {
// Note: device orientation is flipped compared to video orientation. When UIDeviceOrientation
// is landscape right the video orientation should be landscape left.
return AVCaptureVideoOrientationLandscapeLeft;
} else if (deviceOrientation == UIDeviceOrientationPortraitUpsideDown) {
return AVCaptureVideoOrientationPortraitUpsideDown;
} else {
return AVCaptureVideoOrientationPortrait;
}
The above is based on the value transfer direction of flutter, and the following is based on the direction of real equipment. Are there any special scenes
Why does videoOrientation not follow deviceOrientation?
Doing so will cause the up and down directions of the custom camera UI to be reversed
