Regarding the alias file, you must put the default rule last. The first match is always used, so rules below the default rule will never be read.
MyStream=rtsp://192.168.0.104/axis-media/media.amp
MyServer=rtmp://192.168.0.251/rtplive2
*=${Stream.Name}
But with JW player I know it’s not necessary to use an alias with rtsp stream, so it seems like it is another problem.
Be careful not to break this other ways while try to work this out, maybe we should start from the top. I would comment out the StreamNameAlias module for the moment.
I’m using axis camera. I followed this guide to setting up the application:

Have you tried with the Wowza example player, SimpleVideoStreaming?
