how to generate spatial video file

To generate a spatial video file, you can follow the steps outlined in the session "Build compelling spatial photo and video experiences" from WWDC 2024. Here's a summary of the process:

1. Set Up AV Capture Session:

   • Create an AV capture session.
   • Add an AV capture device, setting it to the default system preferred camera.
   • Add an input and an output to the session.
   • Commit the configuration and start running the session.

2. Enable Spatial Video Recording:

   • Change the AV capture device to use the built-in dual wide camera, as spatial video requires both the wide and ultra-wide cameras to stream simultaneously.
   • Select a video format that supports spatial video by iterating through the formats in the video device and checking if isSpatialVideoCaptureSupported is true.
   • Set isSpatialVideoCaptureEnabled to true if spatial video capture is supported. Note that this feature is only available on the iPhone 15 Pro.

3. Handle Output:

   • The movie file output will manage the output and write the spatial video file to disk. The complexity of synchronization, camera calibration, encoding, and metadata writing is abstracted away, providing a fully formed spatial video file.

4. Enhance Quality:

   • For improved video stabilization, set the preferred video stabilization mode to cinematic extended enhanced.
