+**Risk Level**: HIGH
+
+### Objectives
+- [ ] Analyze format usage statistics
+- [ ] Reduce transcoding dependency
+- [ ] Implement format conversion pipeline (if needed)

+- [ ] Final performance optimization
+
+### Decision Matrix for Format Support
+
+| Format | Current Support | ArtPlayer Support | Action Required |
+|--------|----------------|-------------------|-----------------|
+| MP4 (H.264) | ✅ Transcoding | ✅ Native | **Migrate to ArtPlayer** |
+| WebM (VP9) | ✅ Transcoding | ✅ Native | **Migrate to ArtPlayer** |
+| MKV | ✅ Transcoding | ⚠️ HLS Only | **Evaluate HLS conversion** |
+| AVI | ✅ Transcoding | ⚠️ HLS Only | **Evaluate HLS conversion** |
+| MOV | ✅ Transcoding | ⚠️ HLS Only | **Evaluate HLS conversion** |
+| WMV | ✅ Transcoding | ❌ Limited | **Keep transcoding fallback** |
+| FLV | ✅ Transcoding | ❌ Limited | **Keep transcoding fallback** |
+
+### Transcoding Reduction Strategy
+
+#### Option 1: Pre-conversion Pipeline
+```typescript
+// src/lib/video-conversion-pipeline.ts
+export const convertToHLS = async (videoPath: string): Promise<string> => {
+  // Convert problematic formats to HLS during off-peak hours
+  // Store HLS version alongside original
+  // Serve HLS version to ArtPlayer
+  
+  const hlsOutputPath = `${videoPath}.hls/index.m3u8`;
+  
+  // Background conversion process
+  await scheduleHLSConversion(videoPath, hlsOutputPath);
+  
+  return hlsOutputPath;
+};
+```
+
+#### Option 2: Smart Fallback System
+```typescript
+// src/lib/smart-video-server.ts
+export const getOptimalVideoUrl = (video: VideoFile): VideoUrl => {
+  const format = detectVideoFormat(video);
+  
+  if (format.supportLevel === 'native') {
+    return { url: format.directUrl, player: 'artplayer' };
+  }
+  
+  if (format.supportLevel === 'hls' && format.hlsUrl) {
+    return { url: format.hlsUrl, player: 'artplayer' };
+  }
+  
+  // Fallback to current transcoding system
+  return { url: format.transcodedUrl, player: 'current' };
+};
+```
+
+### Code Removal Strategy
+- [ ] Remove FFmpeg process management
+- [ ] Clean up transcoding API endpoints
+- [ ] Remove anti-jitter hooks (if ArtPlayer performs well)
+- [ ] Update database schema
+- [ ] Remove video analysis utilities

+# Complete Video Player Replacement Plan
+
+## Executive Summary
+
+This document outlines a comprehensive plan to completely replace the current custom video player implementation with ArtPlayer + hls.js, eliminating the FFmpeg transcoding system unless absolutely necessary.
+
+## Current State Analysis
+
+### Existing Architecture
+- **Custom HTML5 video player** with advanced transcoding pipeline
+- **FFmpeg-based process management** with anti-jitter technology
+- **Complex format support** through real-time transcoding
+- **Process deduplication** and heartbeat mechanisms
+- **Anti-jitter progress tracking** and protected duration handling
+
+### Pain Points Identified
+- Transcoding system complexity and maintenance overhead
+- FFmpeg process management reliability issues
+- High resource consumption for video processing
+- Complex deployment requirements
+- Browser compatibility limitations for certain formats
+
+## Proposed Solution: ArtPlayer + hls.js Integration
+
+### Core Technology Stack
+- **ArtPlayer.js**: Modern, lightweight video player (18-25kB gzipped)
+- **hls.js**: HLS streaming support with adaptive bitrate
+- **Native browser capabilities**: Leverage built-in format support
+
+### Architecture Changes
+
+#### Before (Current)
+```
+Video File → FFmpeg Transcoding → Process Management → HTML5 Player → User
+```
+
+#### After (Proposed)
+```
+Video File → Format Detection → [Direct Streaming | HLS Streaming | Fallback] → ArtPlayer → User
+```
+
+## Implementation Strategy
+
+### Phase 1: Foundation Setup (Week 1-2)
+
+#### Dependencies Installation
+```bash
+npm install artplayer hls.js artplayer-plugin-hls
+```
+
+#### Core Component Development
+- Create unified `ArtPlayerWrapper` component
+- Implement format detection logic
+- Set up basic HLS integration
+- Maintain existing bookmark/rating APIs
+
+### Phase 2: Feature Parity (Week 2-3)
+
+#### Essential Features Migration
+- Keyboard shortcuts (Space, arrows, F, M)
+- Fullscreen support with proper exit handling
+- Progress tracking and resume functionality
+- Bookmark integration with real-time updates
+- Star rating system compatibility
+
+#### UI/UX Enhancements
+- Modern player controls with ArtPlayer theming
+- Picture-in-picture mode support
+- Playback speed controls (0.5x - 2.0x)
+- Advanced subtitle support (VTT, SRT, ASS/SSA)
+- Mini-player functionality for multitasking
+
+### Phase 3: Streaming Architecture (Week 3-4)
+
+#### Format Support Strategy
+
+**Tier 1: Direct Streaming (Native Browser Support)**
+- MP4 (H.264, H.265)
+- WebM (VP8, VP9)
+- OGG (Theora)
+- Direct file serving with HTTP range requests
+
+**Tier 2: HLS Streaming (ArtPlayer + hls.js)**
+- Adaptive bitrate for network optimization
+- Live streaming support
+- Advanced error recovery
+- Multi-audio track support
+
+**Tier 3: Fallback Mode**
+- Simple file serving for unsupported formats
+- Basic playback without advanced features
+- User notification for limited functionality
+
+#### API Endpoint Modifications
+
+**New Endpoints:**
+```typescript
+// Direct file streaming
+GET /api/stream/direct/:id
+
+// HLS playlist generation (when needed)
+GET /api/stream/hls/:id/playlist.m3u8
+GET /api/stream/hls/:id/segment/:segment
+
+// Format detection
+GET /api/video/:id/format
+```
+
+**Deprecated Endpoints:**
+```typescript
+// Remove transcoding endpoints
+DELETE /api/stream/:id/transcode
+DELETE /api/ffmpeg/*
+```
+
+### Phase 4: Transcoding System Removal (Week 4-5)
+
+#### Code Cleanup
+- Remove FFmpeg dependencies and configurations
+- Delete process management system
+- Clean up anti-jitter hooks and utilities
+- Remove video analysis utilities
+- Update database schema (remove codec_info dependency)
+
+#### Dependency Reduction
+```bash
+# Remove FFmpeg-related packages
+npm uninstall fluent-ffmpeg
+# Remove process management utilities
+# Remove video analysis dependencies
+```
+
+## Technical Implementation Details
+
+### New Player Component Architecture
+
+```typescript
+// src/components/artplayer-wrapper.tsx
+import Artplayer from 'artplayer';
+import Hls from 'hls.js';
+
+interface ArtPlayerWrapperProps {
+  video: VideoFile;
+  onProgress: (time: number) => void;
+  onBookmark: () => void;
+  onRate: (rating: number) => void;
+}
+
+export const ArtPlayerWrapper: React.FC<ArtPlayerWrapperProps> = ({
+  video,
+  onProgress,
+  onBookmark,
+  onRate
+}) => {
+  const playerRef = useRef<Artplayer>(null);
+  const containerRef = useRef<HTMLDivElement>(null);
+
+  useEffect(() => {
+    const player = new Artplayer({
+      container: containerRef.current,
+      url: getVideoUrl(video),
+      type: getVideoType(video),
+      plugins: getPlugins(video),
+      // Maintain existing features
+      subtitle: {
+        url: video.subtitleUrl,
+        type: 'vtt',
+        style: {
+          color: '#fff',
+          fontSize: '20px',
+        }
+      },
+      // Feature parity configuration
+      fullscreen: true,
+      fullscreenWeb: true,
+      pip: true,
+      playbackRate: true,
+      aspectRatio: true,
+      screenshot: true,
+      hotkey: true,
+    });
+
+    // Integrate with existing systems
+    player.on('video:timeupdate', () => {
+      onProgress(player.currentTime);
+    });
+
+    playerRef.current = player;
+
+    return () => {
+      player.destroy();
+    };
+  }, [video]);
+
+  return <div ref={containerRef} className="artplayer-container" />;
+};
+```
+
+### Format Detection Logic
+
+```typescript
+// src/lib/video-format-detector.ts
+export const detectVideoFormat = (video: VideoFile): VideoFormat => {
+  const extension = getFileExtension(video.path).toLowerCase();
+  
+  // Tier 1: Direct streaming support
+  const directStreamingFormats = ['mp4', 'webm', 'ogg'];
+  if (directStreamingFormats.includes(extension)) {
+    return {
+      type: 'direct',
+      url: `/api/stream/direct/${video.id}`,
+      mimeType: getMimeType(extension)
+    };
+  }
+  
+  // Tier 2: HLS streaming for optimal experience
+  const hlsSupportedFormats = ['m3u8', 'mp4', 'ts'];
+  if (hlsSupportedFormats.includes(extension)) {
+    return {
+      type: 'hls',
+      url: `/api/stream/hls/${video.id}/playlist.m3u8`
+    };
+  }
+  
+  // Tier 3: Fallback to direct file serving
+  return {
+    type: 'fallback',
+    url: `/api/files/content/${video.id}`,
+    warning: 'Limited playback features for this format'
+  };
+};
+```
+
+### HLS Integration with ArtPlayer
+
+```typescript
+// src/lib/artplayer-hls-plugin.ts
+export const artplayerHlsPlugin = (option) => {
+  return (art) => {
+    const hls = new Hls();
+    
+    hls.loadSource(option.url);
+    hls.attachMedia(art.video);
+    
+    hls.on(Hls.Events.MANIFEST_PARSED, () => {
+      // Auto-select optimal quality level
+      const levels = hls.levels;
+      const autoLevel = hls.autoLevelEnabled;
+      
+      if (levels.length > 1 && autoLevel) {
+        art.controls.updateQualitySelector(levels);
+      }
+    });
+    
+    hls.on(Hls.Events.ERROR, (event, data) => {
+      handleHlsError(art, hls, data);
+    });
+    
+    return {
+      name: 'hls',
+      hls: hls
+    };
+  };
+};
+```

+USAGE INSTRUCTIONS:
+1. Save this as test-hls.html in your project root
+2. Navigate to http://localhost:3000/test-hls.html
+3. Click the test buttons to verify HLS functionality
+4. Check browser console for detailed debug information
+-->
+
+<!-- 
+DEBUG CHECKLIST:
+- Check browser console for HLS.js debug output
+- Verify playlist loads correctly (should show M3U8 content)
+- Test segment loading (should return binary data)
+- Check network tab for any CORS or loading issues
+- Verify error handling works by testing with invalid IDs
+-->
+
+<!-- 
+COMMON ISSUES:
+1. 404 errors: Check that routes are properly registered
+2. CORS issues: Verify CORS headers in API responses
+3. HLS.js errors: Check browser compatibility and version
+4. Segment loading failures: Verify file paths and permissions
+5. Playlist parsing errors: Check M3U8 format validity
