bilitube
bilitube is a small command-line tool I wrote for my own use. It publishes the programming screencasts on my YouTube channel: it uploads a finished video, sets its title, description, chapters, tags and thumbnail, and adds subtitle tracks in English, Chinese, Spanish and Russian.
It runs on my own computer, signs in to my own Google account, and only ever touches my own channel. It is not a service, it has no other users, and it is not offered to anyone else.
