Number of viewers export?
when I run a livestream I usually start an ec2 instance and copy the public dns name to a database, where I pull it via php to display the stream with a flash viewer at my website.
Works perfectly, and I don't mess with the settings of the preinstalled wowza server.
is there a more-or-less easy way to get the number of current viewers (total) of a running stream?
There are xml live stats available at http://wowza-ip:8086/connectioncounts.
You will need to set a user name and password in conf/admin.password. It defaults to digest authentication but you can set it to basic authentication by editing VHost.xml and setting the AuthenticationMethod to admin-basic or disable it by setting it to none.
All these settings can be made when you start an ec2 instance by using a custom startup package. refer to the EC2 users guide for instructions.
