media-audio-download: Скилл скачивания аудио из видео

--- name: media-audio-download description: "Download audio tracks from video links for transcription/summarization. Docker-first (no host Python): uses yt-dlp+ffmpeg for Bilibili and Playwright extraction for Xiaohongshu note pages. Use when a platform skill needs an audio file for STT (e.g. Bilibili “No subtitles found”, Xiaohongshu video notes), or when the user asks “把这个视频音频下载下来/做逐字稿”." --- # Media Audio Download (Docker) This skill turns a **video URL** into an **audio file** you can feed into an STT skill (e.g. `whisper-transcribe-docker`). Supported (best-effort): - Bilibili video URLs (via `yt-dlp`) - XiaoHongShu note URLs (via Playwright -> extract `masterUrl` -> `ffmpeg` extract audio) ## Quick Start Build image: ```bash docker build -t moltbot-media-audio-download {baseDir} ``` Download audio from a URL into a host folder: ```bash mkdir -p out docker run --rm -v "$PWD/out:/out" moltbot-media-audio-download --url 'https://www.bilibili.com/video/BV...' ``` ### Auth via CookieCloud (recommended) If the page requires login cookies, pass CookieCloud env vars into the container. CookieCloud server URL (inside Docker): - Windows/macOS: `http://host.docker.internal:8088` - Linux: may require `--add-host=host.docker.internal:host-gateway` Example: ```bash docker run --rm -v "$PWD/out:/out" -e COOKIECLOUD_SERVER_URL='http://host.docker.internal:8088' -e COOKIECLOUDUUID='COOKIECLOUD_UUID_HERE' -e COOKIECLOUDPASSWORD='COOKIECLOUD_PASSWORD_HERE' moltbot-media-audio-download --url 'https://www.bilibili.com/video/BV...' ``` ### XiaoHongShu notes that require `xsec_token` Many XHS notes need an `xsec_token` to browse. Avoid shell escaping by passing it separately: ```bash docker run --rm -v "$PWD/out:/out" -e COOKIECLOUD_SERVER_URL='http://host.docker.internal:8088' -e COOKIECLOUDUUID='COOKIECLOUD_UUID_HERE' -e COOKIECLOUDPASSWORD='COOKIECLOUD_PASSWORD_HERE' moltbot-media-audio-download --note-id <noteId> --xsec-token <xsec_token> ``` ## Output - Default output dir: `/out` (mount a host directory there). - Default format: `m4a` (good for Whisper/faster-whisper). - Use `--json` to get machine-readable output (path, platform, ids).
