I set the device format and colorspace to Apple Log and turn off the HDR, why the movie output is still in HDR format rather than Prores Log?
func setup(){
session.sessionPreset = .inputPriority
// get the back camera
let deviceDiscoverySession = AVCaptureDevice.DiscoverySession(deviceTypes: [.builtInWideAngleCamera], mediaType: .video, position: .back)
backCamera = deviceDiscoverySession.devices.first!
try! backCamera.lockForConfiguration()
backCamera.automaticallyAdjustsVideoHDREnabled = false
backCamera.isVideoHDREnabled = false
let formats = backCamera.formats
let appleLogFormat = formats.first { format in
format.supportedColorSpaces.contains(.appleLog)
}
print(appleLogFormat!.supportedColorSpaces.contains(.appleLog))
backCamera.activeFormat = appleLogFormat!
backCamera.activeColorSpace = .appleLog
print("colorspace is Apple Log \(backCamera.activeColorSpace == .appleLog)")
backCamera.unlockForConfiguration()
do {
let input = try AVCaptureDeviceInput(device: backCamera)
session.addInput(input)
} catch {
print(error.localizedDescription)
}
// add output
output = AVCaptureMovieFileOutput()
session.addOutput(output)
let connection = output.connection(with: .video)!
print(
output.outputSettings(for: connection)
)

previewSource = DefaultPreviewSource(session: session)
queue.async {
self.session.startRunning()
}
}Is there anything I missed?
The video output from the app.
The video output from the system camera.
