How can I add support for downloading audio-only files in the Video Downloader template?

To add audio-only download support, you can modify the download_video function in routes.py. Here's an example of how to implement this:

```python @app.route("/download", methods=["POST"]) def download_video(): try: data = request.get_json() if not data or 'url' not in data: return jsonify({"error": "No URL provided"}), 400

       url = data['url']
       format_type = data.get('format', 'video')  # Default to video if not specified

       with tempfile.TemporaryDirectory() as temp_dir:
           ydl_opts = {
               'format': 'bestaudio/best' if format_type == 'audio' else 'best',
               'outtmpl': os.path.join(temp_dir, '%(title)s.%(ext)s'),
               'postprocessors': [{
                   'key': 'FFmpegExtractAudio',
                   'preferredcodec': 'mp3',
                   'preferredquality': '192',
               }] if format_type == 'audio' else [],
           }

           # Rest of the function remains the same

```

This modification allows users to specify whether they want to download the video or just the audio.

How can I implement a download progress indicator in the Video Downloader template?

To add a download progress indicator, you'll need to modify both the backend and frontend. Here's a basic example:

In routes.py, modify the download function to use a custom progress hook:

```python def progress_hook(d): if d['status'] == 'downloading': progress = d['downloaded_bytes'] / d['total_bytes'] * 100 socketio.emit('download_progress', {'progress': progress})

@app.route("/download", methods=["POST"]) def download_video(): # ... existing code ... ydl_opts = { # ... existing options ... 'progress_hooks': [progress_hook], } # ... rest of the function ... ```

In home.js, add a WebSocket listener for progress updates:

javascript const socket = io(); socket.on('download_progress', (data) => { const progressBar = document.getElementById('progress-bar'); progressBar.style.width = `${data.progress}%`; progressBar.textContent = `${Math.round(data.progress)}%`; });

This implementation uses WebSockets to provide real-time progress updates in the Video Downloader interface.
