Currently I have a setup like this:
transcoder -> multicast stream (h264, mpeg2-ts) -> wowza origin -> rtmp/hls/smoothstreaming -> wowza edge -> devices (pc, android, ios, windows)
There are certain intervals when I want to stop/start a live stream remotely, from an automation system. Is there an URL on the Wowza Media Server that allows me to do it via POST/GET URL calls to the origin server?
I'm interested in this as well. If I understand correctly the MediaCaster API is local to the Wowza server machine. So I'm guessing that JMX is not something that can control streams, and I need to pursue this HTTP provider to accomplish this?
Wowza HTTPProviders is the easiest option for integration. Any system that can load an HTTP resource and handle the response can use a Wowza HTTPProvider for integration.
If you take a look at the guide that Sal posted above, there are two examples, and they both start MediaCaster streams. The 2nd one is more complete, but they are both basic starting places, that could be used as-is in many cases.
