Introduction

What is Wowza nDVR?

owza™ nDVR provides the ability to record a live stream with Wowza Streaming Engine™ software while simultaneously allowing users to play or pause a live stream,

Setup for client playback of recorded streams is similar to playback of live streams from a Wowza Streaming Engine server.
