Provide a description that is worded well enough to be understood

propose optional integration of Whisper.cpp into yt-dlp,
to be able to use its srt output directly for embedding subs.

offline, supports translating other languages to English, alternative to other machine-translated.

tiniest dataset was able to accurately transcribe 20 seconds of English audio (5 sentences, 50 words), in just 6 seconds.

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
