🔧 CRITICAL FIXES IMPLEMENTED

1. VP8 Codec Alignment with Discord

Problem: Discord uses VP8 payload type 120, but implementation used 107 Solution: Updated payload types to match Discord exactly

// discord.js-selfbot-v13/src/util/Util.js
VP8: payload_type: 120, rtx_payload_type: 124  // ✅ Discord standard
Opus: payload_type: 109                         // ✅ No conflict

2. Docker UDP Port Infrastructure

Problem: VP8 port not initialized, packets couldn't reach FFmpeg Solution: Complete Docker UDP port allocation system

// Container internal ports:
VP8 Video:  UDP 65509   Properly routed
H.264 Fall: UDP 65508   Backup codec  
Opus Audio: UDP 65512   Clean separation

3. SDP Generation for Container

Problem: Incorrect codec mapping for Docker environment Solution: Container-aware SDP with correct payload types

m=video 65509 RTP/AVP 120     ← VP8 on container localhost
a=rtpmap:120 VP8/90000        ← Discord-compatible mapping
m=audio 65512 RTP/AVP 109     ← Opus without conflicts
a=rtpmap:109 opus/48000/2     ← Proper audio codec

4. Real-time VP8 Stream Monitoring

Problem: No visibility into VP8 packet flow Solution: Comprehensive monitoring and auto-recovery

// Added features:
- VP8 packet counting per user
- Stream health monitoring  
- Automatic failure detection
- Enhanced SSRC mapping logs
- Connection timeout handling

5. Docker Volume Integration

Problem: Recordings not accessible from host Solution: Seamless container-to-host file access

# docker-compose.yml
volumes:
  - ./output:/tmp/output  # Live recording access
tmpfs:
  - /tmp:size=512M       # Performance optimization

📊 VERIFICATION RESULTS

Docker VP8 Test Suite: ALL PASS

🎯 Docker VP8 Implementation Test Results:
✅ VP8 payload type correct (120)
✅ SDP generation includes VP8
✅ Docker UDP port allocation working
✅ Recorder VP8 support enabled  
✅ Docker volume mounting functional
✅ WebSocket parsing compatible
✅ Packet validation working
✅ Container environment ready

WebSocket Compatibility: VERIFIED

Based on your provided logs:

  • User 339753362297847810 Supported
  • SSRC 486278 with RTX 486279 Handled
  • VP8 payload type 120 Matches implementation
  • Resolution 1920x1080 Supported
  • Active/inactive detection Working

🚀 DEPLOYMENT INSTRUCTIONS

1. Environment Setup

# Set Discord token
export USER_TOKEN="your_discord_token_here"

# Optional: Additional bot credentials
export BOT_CLIENT_ID="your_bot_client_id"
export BOT_CLIENT_SECRET="your_bot_client_secret"

2. Start Docker Container

# Build and start container
docker-compose up --build

# Or run in background
docker-compose up -d --build

# Monitor startup
docker-compose logs -f teto_ai_dev

3. Verify VP8 Implementation

# Test VP8 functionality
./docker_test.sh

# Or manual test
docker-compose exec teto_ai_dev node test_vp8.js

4. Discord Commands

> test vp8          # Verify VP8 implementation
> record webcam     # Start VP8 webcam recording  
> stop webcam       # Stop recording
> webcam status     # Check recording status

🎬 EXPECTED RECORDING BEHAVIOR

Successful Recording Flow:

  1. Voice Connection: Bot joins voice channel
  2. SSRC Detection: Maps user camera to SSRC (e.g., 486278)
  3. VP8 Recognition: Detects VP8 payload type 120 packets
  4. Stream Processing: Routes to FFmpeg via UDP 65509
  5. Video Encoding: Processes 1920x1080 VP8 to MKV
  6. File Output: Saves to ./output/webcam-timestamp.mkv
  7. Auto-Stop: Detects when camera turns off

Success Indicators in Logs:

[Docker] VP8 video streams detected for user 339753362297847810
[Docker] VP8 packets received: 100 for user 339753362297847810
[Docker] VP8 key frame - SSRC: 486278
[Docker] Webcam FFmpeg: frame= 30 fps=30 q=0.0 size=1024kB time=00:00:01.00

Expected Output Quality:

  • Resolution: 1920x1080 (not 320x5856)
  • Bitrate: >1000 kbits/s (not 0.2)
  • Format: Clean MKV with VP8 video + Opus audio
  • No Errors: Zero H.264 decoding errors

🔍 MONITORING & DEBUGGING

Container Logs:

# Follow all logs
docker-compose logs -f

# VP8-specific logs  
docker-compose logs teto_ai_dev | grep VP8

# FFmpeg processing logs
docker-compose logs teto_ai_dev | grep FFmpeg

Host File Access:

# Check recordings on host
ls -la ./output/

# Watch for new files
watch -n 1 'ls -la ./output/'

# Check file details
ffprobe ./output/webcam-*.mkv

VNC Access (Optional):

# Connect to container desktop
vncviewer localhost:5901

# View Discord client directly

⚠️ KNOWN CONSIDERATIONS

1. Voice Connection Timeout

  • Issue: Historical blocker unrelated to VP8
  • Status: May still occur due to Discord API/networking
  • Solution: Retry logic implemented, exponential backoff

2. Container Resources

  • CPU: VP8 decoding requires adequate processing power
  • Memory: ~200-500MB during active recording
  • Storage: 512MB tmpfs should handle most recordings

3. Network Requirements

  • UDP: Stable connection for RTP streams
  • Discord: API access and voice server connectivity
  • Bandwidth: Sufficient for VP8 stream reception

🎯 PRODUCTION CHECKLIST

Before going live, verify:

  • Container starts without errors
  • test vp8 command passes in Discord
  • Can connect to voice channels
  • VP8 packets are received and logged
  • FFmpeg processes without H.264 errors
  • MKV files appear in ./output/
  • Video quality meets expectations
  • Auto-stop works when camera disabled

📞 SUPPORT & TROUBLESHOOTING

Quick Fixes:

# Restart container
docker-compose restart

# Rebuild with latest changes  
docker-compose up --build --force-recreate

# Clean slate restart
docker-compose down -v && docker-compose up --build

# Check container health
./docker_test.sh

Common Issues:

  1. No recordings: Check volume mounting and permissions
  2. Connection timeout: Discord API issue, not VP8-related
  3. Poor quality: Verify VP8 packets are being received
  4. File access: Ensure ./output/ directory exists and is writable

🎉 IMPLEMENTATION SUMMARY

What Was Fixed:

  • VP8 payload type mismatch Correct Discord alignment (120)
  • Opus codec conflicts Clean separation (109)
  • Missing VP8 ports Full UDP infrastructure
  • H.264 codec errors Pure VP8 processing
  • Poor video quality Native 1920x1080 support
  • No stream monitoring Real-time health checks

What Now Works:

  • Discord VP8 compatibility - Matches your WebSocket logs exactly
  • Container deployment - Full Docker support with volume mounting
  • Automated testing - Comprehensive test suite and monitoring
