Wowza rookie here 
and I tried to look for this info in the forum threads…
I have the following setup:
source (RTSP h.264) > Wowza > VLC client
If I have the source adjust the bit rate/frame rate midstream, where and how does Wowza look for these parameters?
Should the info be in the SDP attribute (a=… sprop-parameter-sets)? Any link to tutorials?
Appreciate the help!
I don’t think anything is necessary. Wowza just reflects streams, if the source bitrate changes, Wowza will continue to send that stream with the new settings.

It is probably a connectivity issue with the camera. For debugging it is better to revert to INFO level logging, then turn on just RTSP debugging. You can do it in the .stream file:
{
uri:"rtsp://192.168.1.100:10000",
rtpDebugSession:true
}
Or add to this Property to the Application.xml /MediaCaster Properties container:
<Property>
<Name>debugRTSPSession</Name>
<Value>true</Value>
<Type>Boolean</Type>
</Property>

Any idea why Wowza sends TEARDOWN command almost immediately after the stream PLAY command is sent when the source includes SPS and PPS information in each IDR frame?
This is the Wowza log just before the stream tear down. Wowza’s re-connection attempt will re-establish the session, but then immediately shuts down and just cycles.
Where else can I look to find more debug information?
