General workflow for streaming audio or video. The following steps summarize the workflow for publishing real-time audio and video:

   1. Create a NetConnection object.
   2. Use the NetConnection.connect() method to connect to the application instance on the server.
   3. Create a NetStream object to create a data stream within the connection.
   4. Use the NetStream.attachAudio()method to capture and send audio over the stream and the NetStream.attachCamera() method to capture and send video.
   5. Use the NetStream.publish() method to give the stream a unique name and send data over the stream to the server so that others can receive it. You can also record the data as you publish it, so that users can play it back later.
