I am trying to do an audio only stream. I have just set up a new streaming engine and the RTP stream works in VLC. When I set the RTP stream to go to Wowza it shows the correct bitrate but then when I try to tune in with VLC it will not work… Here is one thing I noticed in the log

```auto
2019-06-24	17:05:01	CDT	comment	server	INFO	200	-	MediaCasterStreamValidator.onValidateMediaCaster[live/_definst_] Stream not healthy [stream startup timeout]: mp4:test.stream	-	-	-	13171.2

```

That mp4 makes me think that wowza is not liking that it is audio only (Mp3, confirmed with VLC)

I also get this warning whenever I (unsucessfully) try to connect with VLC.

```auto
WARN	server	comment	2019-06-24	16:56:58	-	-	-	-	-	12687.73	-	-	-	-	-	-	-	-	Application folder ([install-location]/applications/_defapp_) is missing

```

But I have used the iphone based encoder app and everything works fine with that and VLC. Any indication on where I can look for help with this?
