Mux has introduced a new feature called Direct Uploads that allows users to push content directly to their platform without needing to store the file online first. This simplifies workflows for developers and can be useful in various scenarios such as mobile apps, browser uploads, batch uploads, and command line interfaces. The process involves creating a new direct upload with an authenticated URL that is used by client software to upload content via PUT requests. Mux encourages users to explore the possibilities of Direct Uploads and share their experiences.
