Wowza provide many other services as mentioned below.

3.1 Wowza Streaming Cloud

Wowza provides Wowza Streaming Cloud service which lets you easily stream live video to any device (Like mobile device, TV etc.), scaling automatically to handle audience of any size, anywhere. Inputs of Wowza streaming cloud accept videos from nearly any H.264 encoder, RTSP stream or IP camera and transcode the cloud video to create and deliver high-quality streams in multiple bitrates and different formats that can be played on virtually any device. If you use Wowza Streaming Cloud service, then you don’t have to purchase or maintain hardware (servers), or install or run the software locally. You pay only for the resources you use. You can broadcast to audiences on the scale of large or small, any time and at any location.

Wowza Streaming Cloud provides a simple, browser-based interface to understand what you’re using to capture and encode your video and set your playback options, followed by letting Wowza Streaming Cloud do the remaining work. Wowza Streaming Cloud provides the information you need to connect with your source encoder for your viewers to watch the stream, and then it performs adaptive bitrate (ABR) transcoding on the stream by using the robust, reliable technology you’ve come to expect from Wowza.

4.   4K Video streaming using Wowza streaming engine on Eragon 820 based on Snapdragon 820

To demonstrate Wowza streaming engine, we have created live video streaming demo on Eragon 820 platform based on APQ8096 SoC.  In this demo, for AV capture and streaming, we use applications like Wowza GoCoder or  RTMP application developed by eInfochips. 4K AV stream is started from Eragon820 board and sent to Wowza Streaming Engine. On the other end, the mobile device or video player can playback the live video stream using  Wowza server URL. As you can see in Figure 2.
