Setting up VidiU transcoder to work with Nimble Streamer

Our customers quite often use Teradek VidiU transcoder and ask us how to setup it to work with Nimble Streamer. In this article we are going to show how to configure it.

Teradek VidiU is a portable standalone streaming media encoder on the go that can be mounted on top of cameras. VidiU provides instant transmission of live video signal encoded as H.264 video - to a content delivery network (CDN) of choice. This low cost encoder eliminates the need for expensive encoders and equipment to delivers HD quality video online.

If you have one, please start from Teradek VidiU Quick Start Guide and proceed step-by-step to chapter 5: "Connect to VidiU with a web browser". Leave your Teradek settings window opened, we will return to it after configuring Nimble Streamer.
