How to check whether LiveStream (Audio Only) is up on Wowza or not?

问题

I am streaming from Wowza to Mobile (Android). I am using Vitamio streaming library. The actual flow is like, Wowza don't have live stream up, when my app hits the Wowza, but after a while Wowza gets live stream up. Now I again want to hit the Wowza to check whether live stream up or not.

All I want is, my app should hit the Wowza in every 5 sec to check the stream up or not.

It sounds like you just need to query your Wowza server to see if your stream is active or not. If so, then you can use a Wowza REST API command to query Incoming Streams (you need at least version 4.2+).

For example, to query application "live" for all Incoming Streams, you can send the following command via HTTP:

curl -X GET --header 'Accept:application/json; charset=utf-8' http://localhost:8087/v2/servers/_defaultServer_/vhosts/_defaultVHost_/applications/live/instances/_definst_

You would get a response similar to:

{"serverName":"_defaultServer_","incomingStreams":[{"sourceIp":"<hidden>","isPTZEnabled":false,"applicationInstance":"_definst_","name":"wowzademo.stream","isRecordingSet":false,"isStreamManagerStream":true,"isPublishedToVOD":false,"isConnected":true,"ptzPollingInterval":2000}],"outgoingStreams":[],"recorders":[],"streamGroups":[],"name":"_definst_"}

Which shows that I have an Incoming Stream called "wowzademo.stream" (among other things). You can also change your response to be xml instead of json, if you prefer.

Update

In response to your comment, I would add:

make sure that you are on at least version 4.2+; I would actually recommend using version 4.3 since there were some REST API fixes on the latest version;
If you are on version 4.3, then test with disabling authentication by setting <AuthenticationMethod> and <DocumentationServerAuthenticationMethod> to none under the Root/Server/RESTInterface container of the conf/Server.xml file;
Make sure that you add the restUserHTTPHeaders property to have the value "Access-Control-Allow-Origin:*|Access-Control-Allow-Methods:‌OPTIONS,GET,PUT,DELE‌TE,POST|Access-Contr‌ol-Allow-Headers:Con‌tent-Type".

If the above still does not work for you, try enabling the debug properties by setting <DiagnosticURLEnable> to true, and adding <debugEnable> (set to true/Boolean type) property in the RESTInterface container. You can view the logs generated by checking the access logs in the logs/ directory.
