Getting Started

​
Basic Broadcasting Setup

import { SocialPlusVideo } from '@social-plus/video-sdk';

const broadcaster = new SocialPlusVideo({
  apiKey: 'your-api-key',
  mode: 'broadcaster'
});

// Start broadcasting
await broadcaster.startBroadcast({
  title: 'My Live Stream',
  description: 'Broadcasting live from the event',
  privacy: 'public'
});

​
Broadcasting Flow

  1. Initialize SDK: Set up the broadcasting client
  2. Configure Stream: Set stream parameters (resolution, bitrate, etc.)
  3. Preview Setup: Show camera preview to broadcaster
  4. Start Broadcasting: Begin live transmission
  5. Monitor Stream: Track viewer count, quality metrics
  6. End Broadcasting: Gracefully stop the stream

​
Broadcasting States

The SDK manages several broadcasting states:
  • Idle: Ready to start broadcasting
  • Preparing: Setting up camera and audio
  • Preview: Showing camera preview
  • Broadcasting: Actively streaming
  • Paused: Temporarily paused
  • Stopped: Broadcast ended
  • Error: Something went wrong

​
Quality Management

​
Adaptive Streaming

The SDK automatically adjusts stream quality based on:
  • Network bandwidth
  • Device capabilities
  • Viewer feedback
  • Server load

​
Manual Quality Control

Broadcasters can also manually control:
  • Video resolution (480p, 720p, 1080p)
  • Frame rate (15fps, 30fps, 60fps)
  • Bitrate limits
  • Audio quality settings

​
Platform Considerations
