YouTube ASR Summarize (Local)

Other

Summarize YouTube videos with NO subtitles by doing local ASR (yt-dlp + faster-whisper) and extracting a few screenshot frames via ffmpeg. Use when the user asks to summarize the latest video from a channel and YouTube timedtext/subtitles are empty, or when no API tokens/keys should be used.

source .venv/bin/activate
pip install faster-whisper

python3 scripts/youtube_asr_summarize.py \
  --url "https://www.youtube.com/watch?v=<id>" \
  --out "/tmp/youtube-asr/<id>" \
  --model small \
  --lang zh \
  --frames 1 \

Notes

Default model small (CPU/int8) is fast; use --model medium for better accuracy.
