video proxy

A video proxy is a service that fetches and re-serves videos from a new URL, similar to an image proxy.

Why
Similar to an image proxy, you should use a video proxy to:
 * Avoid mixed content warnings when serving foreign videos
 * Cache content that may disappear in the future
 * Transcode or otherwise modifying videos before serving them to a client
