Video Uploader 3.0 is a YouTube API-based PHP script that lets you add YouTube uploading functionality to your own website or web application. It allows your users to upload videos directly to your own YouTube Channel, without the need to sign in to YouTube or even have Google Account. The script uses the latest version (3.0) of YouTube Application Programming Interface (API) to upload videos and and set the video's metadata (title, description, tags, status, and category). The script uses Google OAuth 2.0 endpoints to create web server application that use OAuth 2.0 authorization to access Google APIs. OAuth 2.0 allows you to share specific data with an application while keeping your Google Account usernames, passwords, and other information private.
