Adaptive bitrate delivery
Synchronized Multimedia Integration Language (SMIL)
When Wowza nDVR is added to your live workflow, you can leverage the same SMIL files you
may have created for live streaming. The SMIL workflow requires you to have an encoder
that can generate keyframe-aligned, multiple bitrate streams from the same source.
The smil: prefix is used when playing back a group using SMIL files.
To play using Adobe HDS:
http://[wowza-ip-address]:1935/live/smil:myStream.smil/manifest.f4m?DVR
To play using Apple HLS:
http://[wowza-ip-address]:1935/live/smil:myStream.smil/playlist.m3u8?DVR
To play using Microsoft Smooth Streaming:

For more information about how to create SMIL files, see How to do adaptive bitrate
streaming .
Integrating Wowza Transcoder and Wowza nDVR
Wowza Transcoder and Wowza nDVR can work together to transrate/transcode and record
a live stream at the same time. This can be set up with one application and one
configuration. Extra post-processing isn't required. For more information about Wowza
Transcoder, see the
Wowza Transcoder User's Guide .
Wowza nDVR records each output rendition from Wowza Transcoder in a separate directory
structure. If you're using the sample Wowza Transcoder template named
transrate.xml with
a live stream named myStream , then you'll see the following directories created in [install-
dir]/dvr/[app-name]/_definst_/[streamName][.n] :
myStream.0
myStream_160p.0
mySteam_360p.0
