Video Transcript Extraction

When to use

User shares a video URL and wants the spoken content transcribed to text. Works for Bilibili, YouTube, and other platforms by downloading audio and running ASR.

User Preference

Always use this workflow when the user shares a video link. The user explicitly requested: "以后我给你视频你就按照这样识别出给我". Do NOT ask which method to use — just do it.

Workflow

Step 1: Get video info

For Bilibili short URLs (b23.tv), resolve first:

curl -sL -o /dev/null -w "%{url_effective}" "https://b23.tv/xxx"

Extract BV ID from the redirect URL.
