Auto-Skip Silence Feature - Quick Start Guide

🎯 What It Does

Automatically detects and skips silent portions of videos to save time during playback.

---

🚀 Quick Start (3 Steps)

Step 1: Add Props to Your Video Player

import AdaptiveVideoPlayer from '@/components/AdaptiveVideoPlayer';

<AdaptiveVideoPlayer
  sources={[{ quality: '720p', url: '/video.mp4' }]}
  lessonId="lesson-1"
  enableSilenceSkip={true}  // ← Add this
/>

Step 2: Configure (Optional)

<AdaptiveVideoPlayer
  sources={[{ quality: '720p', url: '/video.mp4' }]}
  lessonId="lesson-1"
  enableSilenceSkip={true}
  silenceThreshold={20}        // Adjust sensitivity (5-50)
  minSilenceDuration={1.5}     // Min silence to skip (seconds)
  onSilenceSkip={(start, end) => console.log('Skipped:', start, end)}
/>

Step 3: Use the Feature

• Play your video
• Click the "Skip Silence" button in controls to toggle on/off
• Watch silent portions get automatically skipped!

📖 Examples

Example 1: Basic Usage

<VideoPlayer
  videoId="video-1"
  videoUrl="/lecture.mp4"
  title="Introduction to Blockchain"
  enableSilenceSkip={true}
/>

Example 2: With Custom Settings

<VideoPlayerSync
  videoId="video-2"
  src="/tutorial.mp4"
  enableSilenceSkip={true}
  silenceThreshold={25}
  minSilenceDuration={1.0}
/>

Example 3: With Callback

<AdaptiveVideoPlayer
  sources={[{ quality: '720p', url: '/course.mp4' }]}
  lessonId="lesson-5"
  enableSilenceSkip={true}
  onSilenceSkip={(start, end) => {
    analytics.track('silence_skip', { start, end });
  }}
/>

🔧 How It Works

1. Analyzes video audio in real-time using Web Audio API
2. Detects when audio level drops below threshold
3. Waits for minimum duration to confirm it's silence
4. Skips forward automatically
5. Tracks total time saved

---

✅ Acceptance Criteria

• ✅ Detect silence - Real-time audio analysis
• ✅ Skip automatically - Seamless forward seeking
• ✅ Toggle feature - Easy on/off control

---

🐛 Troubleshooting

Feature not working?

• Check that enableSilenceSkip={true} is set
• Ensure video has audio track
• Try adjusting silenceThreshold lower (more sensitive)

Skipping too much?

• Increase silenceThreshold (less sensitive)
• Increase minSilenceDuration (skip only longer silences)

Not skipping enough?

• Decrease silenceThreshold (more sensitive)
• Decrease minSilenceDuration (skip shorter silences)
