Configure I-slice keyframe interpretation in Wowza Streaming Engine

By default, I-slices are treated as keyframes by Wowza Streaming Engine™ media server software. If you don't want I-slices to be treated as keyframes, disable the behavior by changing the isISliceKey property for the Wowza Streaming Engine live application.

You can configure the property in Wowza Streaming Engine Manager or by editing [install-dir]/conf/[application-name]/Application.xml. If you make changes to Application.xml, supported settings appear in Wowza Streaming Engine Manager the next time it's started.
