router = APIRouter()

@router.post("/upload-presentation")
async def upload_presentation(
    title: str,
    description: Optional[str] = None,
    slides_file: UploadFile = File(...),
):
    try:
        # Read the uploaded file content
        content = await slides_file.read()
        
        # Save to temporary directory
        with tempfile.NamedTemporaryFile(delete=False) as f:
            f.write(content)
            file_path = f.name
        
        # Process the presentation (e.g., convert to HTML5)
        processed_slides = process_presentation(file_path, title)
        
        # Clean up temporary files
        if os.path.exists(file_path):
            os.remove(file_path)
            
        return {
            "status": status.HTTP_201_CREATED,
            "message": "Presentation uploaded successfully",
            "presentation_id": str(processed_slides.id),
