I struggle to add custom properties to my streams as described in the WWDC22 video https://developer.apple.com/videos/play/wwdc2022/10022/ minute 28:17 The speaker describes using this technique in his CIFilterCam demo (would the source code be available please?) to let the app control which filter the extension should apply. Presumably, there's thus a way to: 1 - define a custom property in the camera extension's stream/device/provider? 2 - be able to use CoreMediaIO (from Swift?) in the app in order to set values of that custom property. This is not documented anywhere I could find. Help and sample code would be greatly appreciated. Thank you. Laurent

It’d be nice if the extension could inherit the permissions given to the main app by the user, in my case screen capture. Alternatively, is there a way to send data to the extension from the app, or vice versa? Especially image or video data. thanks! laurent
