πŸš€ Player Configuration

βš™οΈ Preload Strategy

const player = TCPlayer('player', {
  // Dynamic preload based on network
  preload: navigator.connection?.effectiveType === '4g' 
    ? 'auto' 
    : 'metadata',
  
  // Buffer configuration
  playbackConfig: {
    bufferTime: 30,        // Forward buffer 30s
    maxBufferLength: 60,   // Max buffer 60s
  }
});

🎬 Video Encoding

Recommended encoding:

  • β€’ Video codec: H.264 High Profile, keyframe interval 2-4s
  • β€’ Audio codec: AAC-LC, 128kbps stereo
  • β€’ Resolution ladder: 480p, 720p, 1080p
  • β€’ Bitrate config:
    • - 480p: 800-1200 kbps
    • - 720p: 1500-2500 kbps
    • - 1080p: 3000-5000 kbps

🌐 Network Optimization

πŸ”— CDN and Caching

  • β€’ Geo distribution: Choose CDN nodes close to users
  • β€’ Cache strategy: TS segments 24h, M3U8 playlist 10s
  • β€’ Compression: Enable Gzip to reduce transfer size
  • β€’ HTTP/2: Use HTTP/2 for better concurrency
# CDN cache config example
# .ts files - long cache
Cache-Control: public, max-age=86400

# .m3u8 files - short cache
Cache-Control: public, max-age=10

# CORS config
Access-Control-Allow-Origin: *

πŸ“± Mobile Optimization

iOS Safari Optimization

  • β€’ Inline playback: Set playsinline to avoid fullscreen
  • β€’ Preload limit: iOS limits preload, use preload="none"
  • β€’ Autoplay: Requires user interaction for autoplay
<video id="player"
       playsinline
       webkit-playsinline
       preload="none"
       muted>
</video>

⚑ Advanced Tips

πŸ”„ Smart Pre-caching

Predict user behavior to preload likely content segments

🎯 Segment Optimization

Adjust TS segment size, balance latency and stability, recommend 6-10s

πŸ’Ύ Local Storage

Use IndexedDB to cache frequent segments, reduce network requests

πŸ”€ Load Balancing

Use multiple CDN sources, smart switch to optimal route
