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.

Open Source LLM based Web Chat Interface

This app will be a web interface that allows the user to send prompts to open source LLMs. It requires to enter the openrouter API key for it to work. This api key is free to get on openrouter.ai and there are a bunch of free opensource models on openrouter.ai so you can make a free chatbot. The user will be able to choose from a list of models and have a conversation with the chosen model. The conversation history will be displayed in chronological order, with the oldest message on top and the newest message below. The app will indicate who said each message in the conversation. The app will show a loader and block the send button while waiting for the model's response. The chat bar will be displayed as a sticky bar at the bottom of the page, with 10 pixels of padding below it. The input field will be 3 times wider than the default size, but it will not exceed the width of the page. The send button will be on the right side of the input field and will always fit on the page. The user will be able to press enter to send the message in addition to pressing the send button. The send button will have padding on the right side to match the left side. The message will be cleared from the input bar after pressing send. The last message will now be displayed above the sticky input block, and the conversation div will have a height of 80% to leave space for the model selection and input fields. There will be some space between the messages, and the user messages will be colored in green while the model messages will be colored in grey. The input will be blocked when waiting for the model's response, and a spinner will be displayed on the send button during this time.
