What's New in AVFoundation

1. Spatial Media Integration

  • Recording Spatial Video: AVFoundation now supports recording spatial video, leveraging the new camera setup on the iPhone 15 Pro. This involves using the AV capture session, device input, and movie file output to manage the data flow and write it to disk. The process is similar to recording 2D video but with additional steps to enable spatial video recording.
  • Playback of Spatial Media: AVFoundation can now detect and load spatial media assets. This includes support in PhotoPicker and PhotoKit for filtering and presenting spatial assets.

2. Media Performance Metrics

  • New Metrics System: In iOS 18, AVFoundation introduces a new way to gather media performance metrics represented as events. This helps in triaging issues like playback start delays and stalling by providing client-side metrics, which were previously available through access logs, error logs, and various AV player notifications.

3. Multiview Video Playback in visionOS

  • Multiview Architecture: AVFoundation supports multiview video playback in visionOS, allowing simultaneous viewing of multiple video streams. This is integrated with AVKit and RealityKit to provide a high-quality, customizable viewing experience.
