  • status        - Show system status
  • help          - Show all commands
  • exit          - Exit the program

Command Line Usage

# Transcribe a video file
vt-cli transcribe path/to/video.mp4

# Analyze video metadata
vt-cli analyze path/to/video.mp4

# Search in transcriptions
vt-cli search "artificial intelligence"

# Show system status
vt-cli status

Programmatic Usage

import asyncio
from ai_agent_video_transcription import CoordinatorAgent

async def transcribe_video():
    # Configuration
    config = {
        'transcriber': {
            'model_size': 'base',  # tiny, base, small, medium, large
            'language': 'es'       # Force Spanish transcription
        },
        'formatter': {
            'output_directory': './output'
        },
        'output_formats': ['txt', 'srt']
    }
    
    # Create coordinator
    coordinator = CoordinatorAgent(config)
    
    # Execute transcription
    result = await coordinator.execute({
        'video_path': 'path/to/video.mp4',
        'output_name': 'my_transcription'
    })
    
    return result

# Run transcription
result = asyncio.run(transcribe_video())
print(f"Transcription completed: {result['final_outputs']}")

🔧 Advanced Usage

Batch Processing

# Process multiple videos
videos = ['video1.mp4', 'video2.mp4', 'video3.mp4']
results = await coordinator.execute_batch(videos, 'batch_output')

Custom Memory Queries

# Search in stored transcriptions
memory = MemoryManager()
results = memory.search_transcriptions("machine learning", limit=10)

Quality Analysis

# Analyze video quality before transcription
analyzer = AnalyzerAgent()
metadata = await analyzer.execute({'video_path': 'video.mp4'})
print(f"Quality Score: {metadata['quality_score']}")

🐛 Troubleshooting

Common Issues

FFmpeg not found:

# Verify installation
ffmpeg -version

# Install if missing
brew install ffmpeg  # macOS
sudo apt install ffmpeg  # Ubuntu

Memory issues with large models:

• Use smaller models: tiny, base, small
• Process videos in smaller segments
• Increase system RAM or use GPU acceleration

Transcription in wrong language:

• Set language explicitly: language: "es" in config
• Check audio quality and clarity
• Try different Whisper models

Performance Optimization

• GPU Acceleration: Install CUDA-compatible PyTorch for faster processing
• Model Caching: Models are cached automatically after first use
• Batch Processing: Process multiple videos in sequence for efficiency
