GPUImage3 The front camera is upside down.

When I'm trying to swap camera to the front, the preview is rotated upside down. Any solution?

@gpapoyan95 Can you please attach a small project to repro this?

In my opinion , you can try to transform your renderView to solve this problem

I changed .portrait to .landscapeRight in imageOrientation for front camera and its working fine. @BradLarson please review it if its correct.

func imageOrientation() -> ImageOrientation {
    switch self {
    case .backFacing: return .landscapeRight
    case .frontFacing: return .landscapeRight  // this was  .portrait
    }
}

I add code in Camera.swift if self.location == .frontFacing{ connection.videoOrientation = .landscapeRight } @jagdev7dayz I don't know which solution is better

a soulution i have found to preserve the mirroring aspect (and fixing the upside-down bug) of the front camera is to set in ImageOrientation.swift L15:

case (.landscapeLeft, .portrait): return .rotateClockwiseAndFlipVertically // previously: return .rotateClockwise
