Live Flash video capabilities have improved significantly in the last year, and with the support of major content delivery networks (CDNs) and new encoding tools, it is becoming an affordable solution to reach viewers efficiently across platforms with the best possible user experience.

To improve this even more, and to afford better monetization of content, Flash Media Server enables you to add metadata to the live stream—for instance, for clip information, slides, advertisement, or closed captioning. This article is intended to help you understand the current metadata options and show you how to create your own custom broadcast application using metadata injection.
