Hello, i've recently received the entitlements to access the main camera stream for a project on the Apple Vision Pro.
What happens :
When executing code from this WWDC tutorial , i'm getting this error when trying to use a Camera Frame Provider :
ar_camera_frame_provider_t <0x300d58870>: Failed to start camera stream with error: <ar_error_t: 0x303fcc4c0 Error Domain=com.apple.arkit Code=100 "App not authorized." UserInfo={NSLocalizedFailureReason=Using camera frame provider requires an entitlement., NSLocalizedRecoverySuggestion=, NSLocalizedDescription=App not authorized.}
What I've tried :
I followed the instructions given by mail, by :
adding the .license file at the root of my project,
adding the .entitlements file by adding capabilities in the project (Main Camera Access & Passthrough in screen capture are there).
I've added NSCameraDescription, NSEnterpriseMCAMUsageDescription and NSWorldSensingUsageDescription (they all have a value assigned).
I've also followed those post & post advices.
When checking on the Account settings, i do see the capabilities in the "additional capabilities"
On first launch, I'm also getting prompted to accept the NSEnterpriseMCAMUsageDescription, so I assume the info.plist file is valid?
What did i missed to get the entitlements working ?
Here's the code :
import ARKit
import SwiftUI
import Vision
import RealityKit
class MainCameraAccess {
var arKitSession = ARKitSession()
var cameraFrameProvider = CameraFrameProvider()
var pixelBuffer: CVPixelBuffer?
func startCameraSession() async {
let formats = CameraVideoFormat.supportedVideoFormats(for: .main, cameraPositions: [.left])
// Request authorization
await arKitSession.requestAuthorization(for: [.cameraAccess])
// Start the session
do {
try await arKitSession.run([cameraFrameProvider])
} catch {
print("Failed to start ARKit session: \(error)")
return
}
// Get camera frame updates
guard let cameraFrameUpdates = cameraFrameProvider.cameraFrameUpdates(for: formats[0]) else {
return
}
// Process frames
for await cameraFrame in cameraFrameUpdates {
guard let mainCameraSample = cameraFrame.sample(for: .left) else {
continue
}
self.pixelBuffer = mainCameraSample.pixelBuffer
}
}
func saveLatestImage() {
guard let pixelBuffer = self.pixelBuffer else {
print("No image available to save.")
return
}
// Convert CVPixelBuffer to UIImage
let ciImage = CIImage(cvPixelBuffer: pixelBuffer)
let context = CIContext()
guard let cgImage = context.createCGImage(ciImage, from: ciImage.extent) else {
print("Failed to create CGImage.")
return
}
let uiImage = UIImage(cgImage: cgImage)
// Save UIImage to Photos Album
UIImageWriteToSavedPhotosAlbum(uiImage, nil, nil, nil)
print("Image saved to photo library.")
}
}
Thanks in advance for the help,
Jeremy
