Transvribe

Unfortunately, Transvribe is no longer functional due to significant changes made by YouTube to their internal API.

YouTube has implemented stricter validation requirements for accessing video transcripts. Their API now requires session-specific authentication tokens that cannot be reliably obtained programmatically, making it impossible to extract transcripts without a real browser session.

YouTube's get_transcript endpoint now requires visitorData andconfigInfo fields that are generated per-session and validated against IP addresses and browser fingerprints. These tokens expire quickly and cannot be reused, effectively blocking server-side transcript extraction.

Despite extensive efforts to work around these restrictions, including attempting to extract session tokens dynamically and implementing fallback methods, YouTube's validation is too strict to bypass reliably.

The full codebase is available on GitHub for anyone who wants to explore, fork, or potentially find a solution. If you discover a working approach, I'd love to hear about it!
