We are using AVPlayerViewController to display/play video. Till iOS 15 video player options are visible but for iOS 16 it's not visible. Do we require to make changes for iOS 16 to display video player options?

Hi! I'm trying to move from CoreMedio I/O DAL Plug-In to CoreMedia I/O camera extensions, announced in macOS 12.3. I created a test extension, placed it inside my app bundle into Contents/Library/SystemExtensions and signed with codesigning certificate. But when I try to install my extension from inside my app, using this code (Swift): func requestActivation() { guard case .idle = status else { fatalError("Invalid state") } print("Requesting activation of extension \"\(extensionIdentifier)\"") let req = OSSystemExtensionRequest.activationRequest(forExtensionWithIdentifier: extensionIdentifier, queue: DispatchQueue.main) req.delegate = self OSSystemExtensionManager.shared.submitRequest(req) status = .requested } I'm getting an error: OSSystemExtensionErrorDomain error 8: Code Signature Invalid which is rather generic. Can anybody tell me what I am doing wrong? Or at least propose some steps to find it out? I'm posting here entitlements and codesign output for my extension and containing application for further information. kdg@admins-Mac-mini SystemExtensions % codesign -d --entitlements - ./com.visicom.VirtualCamera.avextension.systemextension Executable=/Applications/VirtualCamera.app/Contents/Library/SystemExtensions/com.visicom.VirtualCamera.avextension.systemextension/Contents/MacOS/com.visicom.VirtualCamera.avextension [Dict] [Key] com.apple.security.app-sandbox [Value] [Bool] true [Key] com.apple.security.application-groups [Value] [Array] [String] 6SUWV7QQBJ.com.visicom.VirtualCamera kdg@admins-Mac-mini /Applications % codesign -d --entitlements - ./VirtualCamera.app Executable=/Applications/VirtualCamera.app/Contents/MacOS/VirtualCamera [Dict] [Key] com.apple.developer.system-extension.install [Value] [Bool] true [Key] com.apple.security.app-sandbox [Value] [Bool] true [Key] com.apple.security.application-groups [Value] [Array] [String] 6SUWV7QQBJ.com.visicom.VirtualCamera [Key] com.apple.security.files.user-selected.read-only [Value] [Bool] true kdg@admins-Mac-mini SystemExtensions % codesign -dvvv ./com.visicom.VirtualCamera.avextension.systemextension Executable=/Applications/VirtualCamera.app/Contents/Library/SystemExtensions/com.visicom.VirtualCamera.avextension.systemextension/Contents/MacOS/com.visicom.VirtualCamera.avextension Identifier=com.visicom.VirtualCamera.avextension Format=bundle with Mach-O universal (x86_64 arm64) CodeDirectory v=20500 size=1553 flags=0x10700(hard,kill,expires,runtime) hashes=37+7 location=embedded Hash type=sha256 size=32 CandidateCDHash sha256=25bd80657bfd6e0ab95467146c7b532817e9e520 CandidateCDHashFull sha256=25bd80657bfd6e0ab95467146c7b532817e9e5209fd50b0cb7ceef40dcfb40e8 Hash choices=sha256 CMSDigest=25bd80657bfd6e0ab95467146c7b532817e9e5209fd50b0cb7ceef40dcfb40e8 CMSDigestType=2 CDHash=25bd80657bfd6e0ab95467146c7b532817e9e520 Signature size=9006 Authority=Developer ID Application: Visicom Media Inc.

I built an app which hosts a CMIOExtension. The app works, and it can activate the extension. The extension loads in e.g. Photo Booth and shows the expected video (a white horizontal line which moves down the picture). I have a couple of questions about this though. The sample Camera Extension is built with a CMIOExtension dictionary with just one entry, CMIOExtensionMachServiceName which is $(TeamIdentifierPrefix)$(PRODUCT_BUNDLE_IDENTIFIER) This Mach service name won't work though. When attempting to activate the extension, sysextd says that the extensions has an invalid mach service name or is not signed, the value must be prefixed with one of the App Groups in the entitlement. So in order to get the sample extension to activate from my app, I have to change its CMIOExtensionMachServiceName to <my team ID>.com.mycompany.my-app-group.<myextensionname> Is this to be expected? The template CMIOExtension generates its own video using a timer. My app is intended to capture video from a source, filter that video, then feed it to the CMIOExtension, somehow. The template creates an app group called "$(TeamIdentifierPrefix)com.example.app-group", which suggests that it might be possible to use XPC to send frames from the app to the extension. However, I've been unable to do so. I've used NSXPCConnection * connection = [[NSXPCConnection alloc] initWithMachServiceName:, using the CMIOExtensionMachServiceName with no options and with the NSXPCConnectionPrivileged option. I've tried NSXPCConnection * connection = [[NSXPCConnection alloc] initWithServiceName: using the extension's bundle identifier. In all cases when I send the first message I get an error in the remote object proxy's handler: Error Domain=NSCocoaErrorDomain Code=4099 "The connection to service named <whatever name I try> was invalidated: failed at lookup with error 3 - No such process." According to the "Daemons and Services Programming Guide" an XPC service should have a CFBundlePackageType of XPC!, but a CMIOExtension is of type SYSX. It can't be both. Does the CMIOExtension loading apparatus cook up a synthetic name for the XPC service, and if so, what is it? If none, how is one expected to get pixel buffers into the camera extension?
