sau youtube login --account creator
sau youtube check --account creator
sau youtube upload-video --account creator --file videos/demo.mp4 --title "标题" --desc "简介" --tags tag1,tag2 --visibility public
Titles can be up to 100 characters.--visibility Optional public、unlisted、private, defaults to public；--thumbnail specifies the thumbnail,--playlist specifies an existing playlist. Only pass --schedule "YYYY-MM-DD HH:MM"when the user explicitly gives a scheduled time; this option uses YouTube Studio's Schedule status, and the date and time shown on the page must be verified.
Before publishing, re-check the account, video, title, description, tags, visibility, and whether the intent is immediate or scheduled. If an upload or publish times out, first check for the original video in YouTube Studio; do not blindly re-upload. A successful upload does not mean review is complete or that the public video is already playable.
