String fullname = appInstance.getApplication().getName() + “/”+ appInstance.getName();

appInstance.setStreamNameAliasProvider(this);

}

…

public String resolvePlayAlias(IApplicationInstance appInstance,

String name, IHTTPStreamerSession httpSession) {

getLogger().debug("[ModuleTimeLimitedURL] Resolve Play HTTPSession: " + name);

…

String streamName = StreamNameAlias(name);

if (streamName == null || “”.equals(streamName)){

httpSession.rejectSession();

getLogger().info(" [ModuleTimeLimitedURL] Reject HTTPSession Session");

}

Hello there.

Are you using the IMediaStreamNameAliasProvider2 interface or the StreamNameAlias AddOn? Or are you using both together?

You cannot use the interface in the same application with the StreamNameAlias AddOn, and you cannot use .stream files if you are using this interface.

Can you please provide some more detail about your implementation?

Thank you.

Hello,

Troubleshooting custom code is beyond the scope of this forum. Can you please test the IMediaStreamNameAliasProvider2 API without the custom code and verify that it does work?

Thank you.

Also please confirm that the stream exists at that point of the resolvePlayAlias event.

If everything checks out without the custom code you can send a zip file of the /lib, /conf and /logs folders to support@wowza.com to open a ticket. And someone will look at this closer.

Thanks again.

Hello…

I used "IMediaStreamNameAliasProvider2 " API for streamNameAlias.

Don’t used duplicate it.

thanks…
