Adaptive Bitrate on a Wowza instance

Can you apply adaptive bitrate on the “standard” version of Wowza on AWS? if not how can you achieve it?

Hi,

You can create your own ABR file by incorporating a number of streams with different bit rates into a smil file,

e.g. if you have a number of streams with different bit rates, or a number of video assets with different bit rates, a simple smil file like this will be all you need:

<smil>
   <head>
   </head>
<body>
  <switch>
     <video src="hi-livestream" system-bitrate="500000"/>
     <video src="lo-livestream" system-bitrate="250000"/>
  </switch>
</body>
</smil>

If you want Wowza to create a number of ABR outputs then you will need to add in the Transcoder AddOn. This will create a number of keyframe aligned streams from a single source, that again you can put into a smil file.

This document describes the various scenarios. Some (such as The Transcoder) may not be available as part of your “standard” version.

I’d recommend contacting sales@wowza.com with a list of your requirements and they’ll point you in the right direction.
