If you’re playing a file called myStream.flv the path would be something like this:
rtmp://[Wowza-IP-Address]:1935/vod/definst/flv:myStream.flv
In Wowza Streaming Engine, the default prefix is now “mp4:” to play a .flv file you must add the “flv:” prefix to the stream name.
If you need more help, type flv streams in the search above for forum posts as there are many discussions on this. Hope that helps
