# Transcoding Removal & Local Player Implementation Design
## Executive Summary
This document outlines the complete technical design for removing all transcoding functionality from NextAV and implementing a local video player fallback system. The goal is to eliminate server-side CPU overhead while maintaining full video format support through local player integration.
## Current State Analysis
### Existing Transcoding Infrastructure
**Active Components:**
- `/api/stream/[id]/transcode` - Full FFmpeg transcoding endpoint
- `/api/stream/[id]` - Main streaming with transcoding redirect logic
- `src/lib/ffmpeg/process-registry.ts` - Process management for FFmpeg
- Video format detection with transcoding fallback
**Transcoding Features:**
- Real-time H.264 encoding with libx264
- Multi-quality output (480p, 720p, 1080p)
- Seek-optimized transcoding with -ss parameter
- Process registry for concurrent session management
- Quality-based bitrate adaptation
**Dependencies:**
- fluent-ffmpeg library
- FFmpeg binary with libx264 support
- Complex process lifecycle management
### Browser Security Constraints
**Critical Limitation:** Modern browsers prohibit automatic local application launching without explicit user interaction (click/keypress). This is a fundamental security requirement that cannot be bypassed.
**Compliance Requirements:**
- All local player launches require user gesture context
- Custom protocol handlers need one-time user authorization
- Browser security policies must be respected
## New Architecture Design
### System Architecture Overview
```

```
### Format Classification Matrix
| Format | Extension | Browser Support | Action Required |
|--------|-----------|-----------------|-----------------|
| **Tier 1: Native** |
| MP4 H.264 | .mp4 | ✅ Universal | Direct ArtPlayer |
| WebM VP9 | .webm | ✅ Chrome/Firefox/Edge | Direct ArtPlayer |
| MP4 HEVC | .mp4 | ⚠️ Platform dependent | Direct ArtPlayer |
| **Tier 2: Local Player** |
| MKV | .mkv | ❌ None | Local Player Required |
| AVI | .avi | ❌ None | Local Player Required |
| WMV | .wmv | ❌ None | Local Player Required |
| FLV | .flv | ❌ None | Local Player Required |
| MOV* | .mov | ⚠️ Limited | Local Player Required |
| TS/M2TS | .ts/.m2ts | ❌ None | Local Player Required |
| **Tier 3: Special Handling** |
| HLS Streams | .m3u8 | ✅ With plugin | ArtPlayer + HLS.js |
*Note: Some MOV files may work in browsers but reliability is low
### API Response Changes
#### Current Transcoding Response

}
```
#### New Local Player Response
```typescript
// NEW: Direct local player guidance
{
type: 'local-player',
supportLevel: 'local-player-required',
url: '/api/stream/direct/123',
action: 'launch-local-player',

| macOS | Safari | Elmedia | ✅ Launches successfully |
| Windows | Chrome | PotPlayer | ✅ Launches successfully |
| Windows | Edge | VLC | ✅ Launches successfully |
| Linux | Firefox | VLC | ✅ Launches successfully |
## Success Criteria
### Functional Requirements
- [ ] All transcoding endpoints return 410 Gone
- [ ] Unsupported formats show local player UI
- [ ] Supported formats work with ArtPlayer
- [ ] Player launch works on macOS and Windows
- [ ] Settings persist across sessions
- [ ] Stream URLs support range requests
### Performance Requirements
- [ ] Zero server CPU usage for video playback
- [ ] Player launch under 2 seconds
- [ ] No memory leaks from removed processes
- [ ] Responsive UI during player launch
### Security Requirements
- [ ] No automatic launches without user interaction
- [ ] Proper URL authentication
- [ ] Clear user consent for protocol handlers
- [ ] No player enumeration vulnerabilities
## Migration Strategy
### Deployment Plan
1. **Phase 1** (Week 1): Disable transcoding endpoints
2. **Phase 2** (Week 2): Deploy format detection changes
3. **Phase 3** (Week 3): Release local player UI
4. **Phase 4** (Week 4): Cleanup and optimization
### Rollback Plan
**If Critical Issues Found**:
1. Revert API endpoints to original transcoding logic
2. Restore original format detection
3. Keep new UI components disabled via feature flag
4. Investigate and fix issues before re-deployment
**Feature Flag Implementation**:
```typescript
const USE_LOCAL_PLAYER_ONLY = process.env.LOCAL_PLAYER_MODE === 'true';
```
## Risk Assessment
### High-Risk Items
1. **Browser Security Restrictions**: Cannot bypass user interaction requirement
2. **Player Installation Dependencies**: Users must have players installed
3. **Network Configuration**: Firewalls may block HTTP streaming
### Mitigation Strategies
1. **Clear User Education**: Provide installation links and setup instructions
2. **Fallback Options**: Always provide stream URL for manual copy/paste
3. **Network Detection**: Provide troubleshooting for common network issues
## Conclusion
This design completely eliminates server-side transcoding while maintaining full video format support through local player integration. The solution respects browser security requirements and provides a seamless user experience through thoughtful UI design and clear user guidance.
