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.
