How donI verify an av composition?

To verify an AV composition, you can follow the steps outlined in the session "Build compelling spatial photo and video experiences" from WWDC 2024. Here is a brief overview of the process:

1. Create an AV Capture Session: Start by creating an AVCaptureSession.
2. Add Device Input: Add an input to the session, which represents input from a capture device like a camera.
3. Add Movie File Output: Add an output to the session, which manages the output and writes it to disk.
4. Connect Input and Output: Connect the input and output with an AVCaptureConnection.
5. Start Running the Session: Commit the configuration and start running the session.

Here is a code snippet to illustrate these steps:

let captureSession = AVCaptureSession()
guard let captureDevice = AVCaptureDevice.default(for: .video) else { return }
let input = try AVCaptureDeviceInput(device: captureDevice)
captureSession.addInput(input)

let output = AVCaptureMovieFileOutput()
captureSession.addOutput(output)

captureSession.startRunning()

To extend this for spatial video recording, you need to:

1. Change the AV Capture Device: Use a device that supports spatial video.
2. Pick a Supported Video Format: Ensure the video format supports spatial video.
3. Enable Spatial Video Recording: Enable spatial video recording on the output.

For more detailed information, you can refer to the session Build compelling spatial photo and video experiences (05:21).
