Feature Request: Built-in Live Stream Recording compatible with demo project

Subject: Feature Request: Built-in Live Stream Recording
Dear Media3 Team,
I'm writing to propose a new feature for Media3: built-in live stream recording.
Problem: Currently, Media3 doesn't provide a native solution for directly recording live streams especially works with Media3 Demo Android Application. Developers often need to rely on custom implementations, which can be complex and resource-intensive.
Proposed Solution: Introduce a new API or extension that allows developers to easily record live streams directly from the Media3 player. This could be achieved by:

1. Exposing a Recording API: Provide a simple API to start, stop, and pause recordings.
2. Offering a Callback Mechanism: Allow developers to access the decoded media data for custom recording implementations.
3. Providing Sample Implementations: Share code examples demonstrating best practices for live stream recording.
   Advantages:

• Simplified Development: Reduces the complexity of implementing live stream recording.
• Improved Performance: Optimized recording capabilities can lead to better performance and reduced resource usage.
• Enhanced User Experience: Enables users to easily record and save their favorite live streams.
• Increased Flexibility: Offers developers more control over the recording process and output formats.
  By incorporating these features, Media3 can become a more powerful and versatile platform for both developers and end-users.
  Thank you for considering this feature request.
  Sincerely,
