Problem

The current video_player plugin relies on native player ABR (ExoPlayer / AVPlayer), but this does not handle all real-world cases of network degradation.

In testing, removing Dart-side adaptive logic resulted in:

• No quality downgrade during buffering
• Playback stalls under poor network conditions

This suggests native ABR alone is insufficient without app-level feedback.

Proposal

Introduce adaptive bitrate control via:

• A public API: setBandwidthLimit(int bitrate)
• Internal Dart-level manager that:
  • Observes buffering events
  • Dynamically adjusts bitrate

Why this is needed

• Native ABR selects quality initially but does not always react to runtime buffering effectively
• Apps need control over bandwidth ceilings
• No existing API in video_player supports this

Platforms affected

• Android (ExoPlayer)
• iOS (AVPlayer)

Proposal Outcome

• Better playback stability under fluctuating networks
• Reduced buffering
• Developer control over bitrate behavior
