Schema v2 Features

What's New:

1. Comprehensive Extraction: ALL behavior occurrences (not just samples)

   • Typical 30min meeting: 300-500+ behavior examples
   • Direct quotes with key phrases (close approximations)

2. Speaker Name Extraction:

   • Reads names from video thumbnails (Zoom/Teams/Meet)
   • Tracks highlighted speaker (blue outline detection)
   • Listens for audio introductions
   • Falls back to S1, S2, S3 if names not found

3. Simplified Structure:

   • 3 levels max nesting (vs 5-6 in v1)
   • Focused on essential coaching metrics
   • More reliable Gemini generation

What's Different from v1:

• ❌ No full utterance-by-utterance transcript
• ❌ No timeline visualization with every statement
• ❌ No Pull→Push transition detection
• ❌ No filler word tracking or question quality metrics
• ❌ No communication scores (clarity/impact/inclusion)
• ✅ Instead: Comprehensive behavior occurrence extraction with quotes
• ✅ Per-participant filtered view of all their behaviors
• ✅ Speaker name identification

Setup Instructions

Prerequisites

• Docker & Docker Compose
• Gemini API key (Get one here)
• Apache web server (optional)

1. Clone and Configure

cd /path/to/rackham_meeting_analyzer

# Set up environment variables
cd infra
cp .env.example .env
nano .env  # Add your GEMINI_API_KEY and generate a JWT_SECRET

Generate a secure JWT secret:

openssl rand -base64 32

Example .env for local development:

MONGO_URL=mongodb://mongo:27017/btg
GEMINI_API_KEY=your_gemini_api_key_here
GEMINI_MODEL=gemini-2.5-pro
JWT_SECRET=your_secure_jwt_secret_here
API_BASE_URL=http://localhost:8080/api
FRONTEND_BASE_PATH=/
CORS_ORIGINS=http://localhost:3009,http://localhost:8080

Example .env for production with reverse proxy:

MONGO_URL=mongodb://mongo:27017/btg
GEMINI_API_KEY=your_gemini_api_key_here
GEMINI_MODEL=gemini-2.5-pro
JWT_SECRET=your_secure_jwt_secret_here
API_BASE_URL=https://ai-sandbox.oliver.solutions/rackham-back
FRONTEND_BASE_PATH=/rackham
CORS_ORIGINS=http://localhost:3009,https://ai-sandbox.oliver.solutions

2. Run Deployment Script

./deploy.sh

This automated script will:

• Build Docker containers (backend, MongoDB)
• Build frontend static files with production optimizations
• Deploy frontend to /var/www/html/rackham
• Start backend services
• Provide Apache configuration instructions

What gets deployed:

• Frontend: Static files at /var/www/html/rackham (served by Apache)
• Backend: Docker container on localhost:8080
• MongoDB: Docker container on localhost:27021

3. Configure Apache

The deploy script will output the exact configuration to add. Add this to /etc/apache2/apache2.conf:

# rackham video analyzer frontend - SPA routing
<Directory /var/www/html/rackham>
    Options -Indexes +FollowSymLinks
    AllowOverride All
    Require all granted

    # Handle React Router (SPA routing)
    RewriteEngine On
    RewriteBase /rackham/
    RewriteRule ^index\.html$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /rackham/index.html [L]

    # Cache static assets
    <FilesMatch "\.(js|css|png|jpg|jpeg|gif|ico|svg|woff|woff2|ttf|eot)$">
        Header set Cache-Control "public, max-age=31536000, immutable"
    </FilesMatch>

    # No cache for index.html
    <FilesMatch "^index\.html$">
        Header set Cache-Control "no-cache, no-store, must-revalidate"
    </FilesMatch>
</Directory>

# rackham video analyzer backend (should already be in your apache2.conf)
ProxyPass /rackham-back/ http://localhost:8080/
ProxyPassReverse /rackham-back/ http://localhost:8080/

Then reload Apache:

sudo systemctl reload apache2

Notes:

• Frontend is served as static files from /var/www/html/rackham (no Docker container needed)
• Backend runs in Docker container and is proxied
• Remove any existing ProxyPass /rackham directives if present

4. Access the Application

How It Works

Video Analysis Flow

1. Upload: User uploads meeting video (up to 2GB) via chunked upload
2. Queue: Job enters FIFO processing queue
3. Upload to Gemini: Video uploaded to Gemini File API (auto-deleted after 48 hours)
4. Analysis: Gemini 2.5 Pro analyzes video with structured output:
   • Speaker diarization (S1, S2, S3, ...)
   • Speaker name extraction from video thumbnails and audio
   • ALL behavior occurrences extracted (300-500+ for 30min video)
   • Direct quotes with key phrases for each occurrence
   • Behavior counting per speaker (11 Rackham behaviors)
   • Pull:Push ratio calculations
   • Speaking time analysis
   • 2-3 coaching action items per speaker
5. Validation: JSON schema validation with up to 2 retries
6. Storage: Analysis saved to MongoDB (90-day TTL)
7. Dashboard: Interactive visualization with per-participant drill-down
8. PDF: Downloadable comprehensive report

Processing Time

• Small videos (5-10 min): ~3-5 minutes
• Medium videos (20-30 min): ~5-10 minutes
• Large videos (45-60 min): ~10-15 minutes
• No timeout - Gemini has unlimited time to complete analysis

Troubleshooting

Backend Issues

Job queue not processing:

• Check Gemini API key is valid and has sufficient quota
• Check video file exists in /data/videos
• View logs: docker logs infra-backend-1 -f
• Ensure using Gemini 2.5 Pro model

MongoDB connection failed:

• Ensure MongoDB container is running: docker ps
• Check MONGO_URL environment variable
• Verify network connectivity: docker network ls

Gemini API errors:

• Verify API key is correct
• Check quota limits at https://aistudio.google.com
• Review logs for specific error messages
• Ensure video is under Gemini's size limits

Speaker names not extracted:

• Check if video has on-screen name labels (Zoom/Teams/Meet)
• Verify people introduce themselves in audio
• Names will show as S1, S2, S3 if not detected (this is expected fallback)

Frontend Issues

API calls failing:

• Check backend is running on port 8080: curl http://localhost:8080/health
• Verify VITE_API_BASE environment variable
• Check CORS settings in backend
• Clear browser cache and cookies

Upload fails:

• Check file size (max 2GB)
• Verify file format (mp4, mov, avi, mkv, webm)
• Check available disk space
• Review browser console for errors

Dashboard not loading:

• Check analysis completed successfully (job status = COMPLETED)
• Verify analysis data structure matches v2 schema
• Check browser console for TypeScript errors
• Ensure backend returned all required fields

Security Notes

• JWT tokens stored in HTTPOnly cookies (secure)
• File upload validation (size, type, sanitization)
• TTL-based data expiration (90 days)
• CORS restricted to configured origins
• Path traversal prevention
• Video files auto-deleted from Gemini after 48 hours
• Reminder: Internal meetings only - do not upload confidential external content

---

Migration from v1 to v2

If you have existing v1 analyses, note these breaking changes:

Schema Changes:

• transcript section removed → use behavior_examples instead
• analysis.timeline removed → use behavior_examples filtered by participant
• analysis.metrics removed → data now in participants array
• analysis.feedback removed → use action_items per participant
• Field renamed: paraphrase → quote
• Field added: name (speaker names)
• Field added: speaker_name (in behavior examples)

Data Structure:

• Old: data.analysis.participants

• New: data.participants

• Old: data.transcript.duration_sec

• New: data.meeting.duration_sec

Frontend Components Removed:

• TimelineVisualization component (no longer needed)
• TransitionsPanel component (no longer needed)
• Communication scores display
• Alert system display

---

Performance Characteristics

Processing Times (Typical):

• Upload: 10-60 seconds (depending on file size)
• Gemini Processing: 5-15 minutes (no timeout - takes as long as needed)
• Validation: < 1 second
• PDF Generation: 2-5 seconds

Data Volumes (30min meeting):

• Behavior occurrences extracted: 300-500+
• Speakers identified: 2-6 typically
• Coaching action items: 4-18 (2-3 per speaker)
• Analysis JSON size: ~200-500 KB
• PDF size: ~150-300 KB

Storage:

• Video retention: Uploaded to Gemini (auto-deleted after 48h)
• Analysis retention: MongoDB with 90-day TTL
• Local video files: Stored in /data/videos, can be cleaned periodically

Troubleshooting Common Issues

"response.text is None" Error

Cause: Pydantic models with default field values (e.g., Optional[str] = None) Solution: Already fixed - we use Optional[str] without defaults

"Unknown field for Schema: additionalProperties"

Cause: Pydantic Config classes with extra = 'forbid' Solution: Already fixed - no Config classes in models

Gemini Returns Only {'version': 'v2'}

Cause: Old google-generativeai SDK bug with nested models Solution: Already fixed - migrated to google-genai==1.47.0

Dependency Conflict: httpx

Cause: google-genai requires httpx>=0.28.1 Solution: Already fixed - requirements.txt updated
