Video Downloader

Overview

Use this skill to turn a video-platform URL into a local source-material folder containing the video file, post_caption.txt, audio.m4a or audio.mp3, transcript.txt, and metadata.json.

Terminology:

• post_caption.txt: platform publish text, title, description, and hashtags.
• transcript.txt: spoken in-video script generated from audio ASR.
• metadata.json: normalized platform metadata plus download and ASR status.

The current implemented providers are Douyin, Bilibili, YouTube, and Xiaohongshu. WeChat Channels is an explicit extension point; do not claim that provider works until its provider module has been implemented and tested. For WeChat Channels links, tell the user to first use the WeChat mini program kg百宝箱 to download the video from the 视频号 link, then continue with local ASR or downstream processing on the downloaded file.
