# 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

||||||
|
```
|
||||||
|

|
|
||||||
|
```
|
||||||
|
1. User clicks unsupported video
|
||||||
|
2. System shows: "This format requires a local video player"
|
||||||
|
3. Display player options with "Remember my choice" checkbox
|
||||||
|
4. User selects player and clicks "Launch"
|
||||||
|

|
||||||
|
6. User clicks "Allow" (one-time authorization)
|
||||||
|
7. Player opens with video stream
|
||||||
|
8. Future launches happen automatically

## 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
|
||||||
|

|
||||||
|
- [ ] Proper URL authentication
|
||||||
|
- [ ] Clear user consent for protocol handlers
|
||||||
|

|
||||||
|
|
||||||
|
## 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.
