Video Recorder Studio

A production-ready, backend-agnostic video recording and transcoding library that enables websites to capture webcam video and automatically convert it to HLS format using AWS services.

Features

• Universal Recording: Works across all modern browsers and devices
• AWS-Powered: Leverages S3, MediaConvert, and CloudFront for scalable processing
• Backend Agnostic: Integrates with any server technology
• Mobile Optimized: Responsive design with mobile-specific optimizations
• Production Ready: Built-in error handling, retry logic, and monitoring
• Customizable: Flexible configuration and styling options
• Progress Tracking: Real-time upload and processing progress
• Secure: Presigned URLs and proper authentication handling

Quick Start

1. Install the Package

npm install @onamfc/video-transcoder

2. Basic Usage

import { VideoRecorder } from '@onamfc/video-transcoder';

const recorder = new VideoRecorder({
  apiEndpoint: 'https://your-api.com/api/video',
  maxDuration: 300,
  videoQuality: 'medium'
});

// Initialize camera
await recorder.initialize();

// Start recording
await recorder.startRecording();

// Stop and upload
const recording = await recorder.stopRecording();
const upload = await recorder.uploadRecording(recording.blob);

// Track progress
recorder.onComplete((result) => {
  console.log('HLS URL:', result.hlsUrl);
  console.log('MP4 URL:', result.mp4Url);
});

3. React Hook

import { useVideoRecorder } from '@onamfc/video-transcoder/react';

function VideoRecorderComponent() {
  const {
    initialize,
    startRecording,
    stopRecording,
    isRecording,
    duration,
    status
  } = useVideoRecorder({
    config: {
      apiEndpoint: 'https://your-api.com/api/video',
      maxDuration: 300
    },
    onComplete: (result) => {
      console.log('Video processed:', result.hlsUrl);
    }
  });

  return (
    <div>
      <button onClick={initialize}>Initialize Camera</button>
      <button onClick={startRecording} disabled={!isInitialized || isRecording}>
        Start Recording
      </button>
      <button onClick={stopRecording} disabled={!isRecording}>
        Stop Recording
      </button>
      <p>Status: {status}</p>
      <p>Duration: {duration}s</p>
    </div>
  );
}

API Reference

VideoRecorder Class

Constructor

new VideoRecorder(config: RecorderConfig)

Methods

• initialize(): Promise<void> - Initialize camera access
• startRecording(): Promise<void> - Start video recording
• stopRecording(): Promise<RecordingResult> - Stop recording and get result
• pauseRecording(): void - Pause current recording
• resumeRecording(): void - Resume paused recording

• onComplete(callback: (result: ProcessingResult) => void): void
• onError(callback: (error: ErrorEvent) => void): void

Configuration

interface RecorderConfig {
  // Required
  apiEndpoint: 'https://your-api.com/api/video',
  
  // Recording Settings
  maxDuration: 300, // 5 minutes
  videoQuality: 'medium', // 'low' | 'medium' | 'high' | 'auto'
  audioEnabled: true,
  
  // Upload Settings
  chunkSize: 5 * 1024 * 1024, // 5MB chunks

}

Backend Integration

Your backend needs to implement these endpoints:

• POST /api/video/upload-token - Generate presigned upload URLs
• GET /api/video/status/:trackingId - Get processing status
• GET /api/video/recordings - List recordings (optional)

See the GitHub repository for complete backend examples and AWS infrastructure setup.
