Implement video codec and quality adaptation

[RUKAYAT-CODER]

Background

Videos served in fixed quality regardless of network speed. Implement adaptive bitrate (ABR) streaming or serve multiple quality versions, lowering quality on slow connections.

Description

Adapt video quality based on network connection speed.

Current Behavior

Fixed video quality regardless of network

Expected Behavior

Lower quality on slow networks, higher on fast

Impact

📶 Better video experience on slow networks
🎬 Fewer buffering events
⚡ Faster playback start

Acceptance Criteria

• Detect network speed (already done)
• Serve video variants (low/medium/high quality)
• Auto-select quality based on network
• Test on various network speeds
• Monitor playback quality metrics
• Document video adaptation strategy

Implementation Hints

Serve video as HLS with multiple bitrates or provide quality selection.

Performance Metrics

Before:

• buffering3G: 50% of videos buffer

After (Target):

• buffering3G: <5% with quality adaptation
