Security Notes

Safe by Design

URL validation: Only accepts YouTube URLs (youtube.com, youtu.be)
Filename sanitization: Removes dangerous characters
Output restriction: Only writes to .tmp/ directory
No shell injection: Uses subprocess with argument lists, not string concatenation
No stored credentials: Cookies only used when explicitly requested

Copyright Warning

Only download content you have rights to access
Respect YouTube's Terms of Service
Do not redistribute copyrighted content
Use for personal/educational purposes

Rate Limiting

yt-dlp has built-in rate limiting
For bulk downloads, use --sleep-interval 5 to avoid throttling
YouTube may temporarily block IPs with excessive requests

Troubleshooting

Issue: "Video unavailable"

Cause: Video is private, age-restricted, or region-locked Solution: Use --cookies-from-browser chrome for age-restricted content

Issue: "Unable to extract video data"

Cause: YouTube changed their page structure Solution: Update yt-dlp: pip install -U yt-dlp

Issue: No subtitles found

Cause: Video has no captions (auto or manual) Solution: Use --list-subs to see available subtitles first

Issue: Slow downloads

Cause: YouTube throttling or network issues Solution: Try --concurrent-fragments 4 for faster downloads

Issue: Format conversion failed

Cause: ffmpeg not installed Solution: Install ffmpeg (see Environment Setup)

Integration Patterns

Download + Transcribe + Summarize

bash

# 1. Download video
python scripts/download_video.py "URL" --output-dir .tmp/video
 
# 2. Get transcript
python scripts/get_transcript.py "URL" --output .tmp/transcript.txt
 
# 3. Use content-generation to summarize
# (transcript file is now ready for summarization)

Bulk Research Workflow

bash

# 1. Get metadata for research videos
python scripts/get_video_info.py --urls-file research_videos.txt --output .tmp/metadata.json
 
# 2. Download transcripts for text analysis
python scripts/get_transcript.py --urls-file research_videos.txt --output-dir .tmp/transcripts
 
# 3. Use parallel-research to analyze content

Course Content Download

bash

# Download entire playlist as course modules
python scripts/download_video.py "PLAYLIST_URL" --output-dir .tmp/course --quality 720p
 
# Get all transcripts for notes
python scripts/get_transcript.py "PLAYLIST_URL" --output-dir .tmp/course/transcripts
