We only build the API's we want to use ourselves. MediaServ was built by The 4 Syndicate, the owner of several other applications. Many of the API's we've built we've needed, including MediaServ. MediaServ is used by applications such as BlabAway and Incline Media.
MediaServ allows us to process videos and photos. It also allows us to store other types of files. We built the API to allow us to do all this efficiently, without having to build a new solution every time we wanted to do anything with files. MediaServ allows us to build new applications very quickly by getting a lot of the extra work out of the way.
We haven't even scratched the surface on MediaServ. Lets Read the Documentation to learn more.
