[Sponsor] Mux Video

Mux is the developer video platform. Use their Video API to build video streaming into your application and make it play beautifully at scale on any device. A Mux stream is just one GET request away from magical-feeling features like automatic thumbnails, animated gifs, and data-driven encoding decisions. Looking for more insight into your video performance? They’ve got that covered too with Data: which viewers are seeing errors or rebuffering, which player or CDN is performing better, and whether or not you should use Mux (trick question, yes).
