How does the Online Video Converter handle different video qualities?
The Online Video Converter dynamically fetches available video qualities using the yt_dlp
library. Here's a code snippet demonstrating this functionality:
```python @app.route('/get_qualities', methods=['POST']) def get_qualities(): url = request.json.get('url') if not url: return jsonify({'error': 'No URL provided'}), 400
try:
with yt_dlp.YoutubeDL() as ydl:
info = ydl.extract_info(url, download=False)
formats = info['formats']
available_qualities = []
for f in formats:
if f.get('height'):
quality = f"{f['height']}p"
file_size = f.get('filesize_approx', 0) / (1024 * 1024) # Convert to MB
available_qualities.append({'quality': quality, 'size': f"{file_size:.2f} MB"})
available_qualities = sorted(available_qualities, key=lambda x: int(x['quality'][:-1]), reverse=True)
return jsonify({'qualities': available_qualities})
except Exception as e:
logger.error(f"Error in get_qualities: {str(e)}")
return jsonify({'error': f'Failed to fetch video info: {str(e)}'}), 500
```
This function retrieves available video qualities and their approximate file sizes, allowing users to choose their preferred quality.
Can you explain how the transcription feature works in the Online Video Converter?
The transcription feature uses the youtube_transcript_api
library to fetch the transcript and then generates a PDF using the fpdf
library. Here's a code snippet demonstrating this functionality:
```python @app.route('/transcribe', methods=['POST']) def transcribe_youtube(): url = request.json.get('url') if not url: return jsonify({'error': 'No URL provided'}), 400
video_id = extract_video_id(url)
if not video_id:
return jsonify({'error': 'Could not extract video ID'}), 400
try:
transcript = YouTubeTranscriptApi.get_transcript(video_id)
pdf_filename = generate_pdf(transcript, video_id)
return send_file(pdf_filename, as_attachment=True, download_name=f"{video_id}.pdf")
except Exception as e:
logger.error(f"Error transcribing video: {str(e)}", exc_info=True)
return jsonify({'error': f'Failed to transcribe video: {str(e)}'}), 500
```
This function extracts the video ID, fetches the transcript, generates a PDF, and sends it as a downloadable file to the user. The Online Video Converter's transcription feature can be particularly useful for content creators, researchers, and accessibility purposes.
