What is it?

Y2A-Auto automates the full pipeline of moving YouTube videos to Chinese video platforms AcFun and bilibili. It downloads videos and covers with yt-dlp, generates or translates subtitles via speech recognition (Whisper, Voxtral) and OpenAI-compatible models, checks subtitle quality, optionally burns subtitles into the video, and uses AI to draft titles, descriptions and tags before uploading.

A built-in web admin panel lets users review tasks, edit metadata, force uploads, and configure accounts, AI, subtitles, transcoding and security. A YouTube monitor can poll channels or keyword searches on a schedule and queue matching videos automatically. Cookies can be imported by hand or synced from CookieCloud, and notifications go to WeCom, Server酱 or message-pusher.

The project runs in Docker or locally with Python 3.11+ and FFmpeg, and supports CPU and NVIDIA, Intel or AMD hardware encoding. Optional Aliyun Green content moderation and a separate Telegram bot for submitting links are available.
