…For this reason I think that this is for clients. …In this case where this file is saved?
It’s saved on the server (not client-side), in the content folder, wherever the /conf/[application]/Application.xml /StorageDir points to. If it’s not there, then it’s not setup correctly.
I don’t know another way to do it. This is the way to record portions of a live stream on the server.
Look in the log for error messages. If you can’t sort it out, zip up the conf and logs folders and send them to support@wowza.com. (if the email bounces please post the zip files to a web server and send a link)
