output/dwarkesh-podcast/Dwarkesh Podcast_2024-01-15_agi-is-still-30-years-away.md
output/20vc/20 Minutes VC (20VC)_2024-03-10_funding-round-analysis.md

Podcast Registry

The registry at scripts/podcasts.json maps each podcast to its RSS feeds, transcript sources, and API endpoints. To add new podcasts:

{
  "id": "new-podcast",
  "name": "New Podcast",
  "rss": "https://example.com/feed.xml",
  "transcript_sources": {
    "primary": {"type": "website_scrape", "url": "https://example.com"}
  }
}

Troubleshooting

| Problem | Solution |

|---------|----------|

| "No transcript found" | Tier 2 (RSS+Whisper) is the recommended approach. If auto mode fails, try --method whisper to force it. |

| RSS fetch fails | RSS feeds may change; check scripts/podcasts.json for current URLs |

| Audio download slow | Large MP3s can take minutes on slow connections |

| Groq rate limited | Wait or switch to local faster-whisper |

| Taddy not returning transcripts | Some episodes lack transcripts; try --method whisper |

| Podcast not in registry | Add it to scripts/podcasts.json |

| Unicode error on Windows | Fixed: script auto-reconfigures stdout to UTF-8; saved files use UTF-8 encoding |

| Audio > 25 MB for Groq | Install ffmpeg: winget install ffmpeg (Windows) or brew install ffmpeg (macOS) |

Common Mistakes

• Forgetting API keys: Set GROQ_API_KEY in your env or .env file
• Relying on Tier 1 free sources: Tier 1 is best-effort and limited. Always fall back to Tier 2 (RSS+Whisper) which is the recommended method.
• Not cloning the Lenny's repo first: The GitHub archive must be cloned locally for Tier 1 to work
• Using --method taddy without TADDY_API_KEY: Falls through silently; set the key or use auto mode
