any advancements in video player features

Yes, there have been several advancements in video player features presented at WWDC. Here are some highlights:

1. Multiview Video Playback in visionOS:

   • Multiview: This feature allows users to watch multiple video screens simultaneously. It supports up to five video screens at once with layout templates that maximize comfort and viewability. Users can switch the main focus between videos, and the audio will follow the main focus video. This feature is integrated with AVKit and AVPlayerViewController, providing a familiar user interface and enhanced video viewing capabilities on visionOS.
   • Content Browser: A content browser is available to add and remove videos, making it intuitive for users to interact with multiple video screens (Explore multiview video playback in visionOS).

2. Media Performance Metrics in AVFoundation:

   • Enhanced Metrics for HLS Streaming: In iOS 18, there are enhanced metrics available for HLS streaming assets, providing more data points and detailed insights into media playback performance. This includes access logs, error logs, and various AV player notifications (Discover media performance metrics in AVFoundation).

3. Spatial Photo and Video Experiences:

   • AVPlayer View Controller: This cross-platform API supports both 2D and 3D video content, making it a versatile option for displaying various types of video content with a consistent presentation style. It also supports HTTP Live Streaming for spatial video (Build compelling spatial photo and video experiences).
   • Full-Screen Spatial Video: Spatial videos can be displayed in full-screen mode, enhancing the immersive experience. The AVPlayer View Controller will use the 3D video presentation in full-screen mode (Build compelling spatial photo and video experiences).

4. Window Placement for Video Players in macOS:

   • Adjust Window Placement: The video player window can be adjusted to fit the best position and size given the video and the screen it is playing on. This ensures optimal viewing experiences across different monitor configurations (Tailor macOS windows with SwiftUI).
