Seems that the default stream prefix can only be set for the whole server.

wowza 4 has the default stream prefix set to mp4 while previous wowza has it set to flv.

The problem is now that we have imported some applications from wowza 3 don’t work as the web sites are using the old URL which doesn’t have the stream prefix flv: in it.

We can’t change the current server stream prefix because the new applications are using mp4: as default.

So, is there a way to set the default stream prefix to flv in wowza 4 only for some applications? like putting it in application.xml

Sorry, but as far as I am aware this is not supported.

Kind regards,
