Question
SMIL based variable bandwidth playlists for streaming flash video from Flash Media Server 2
I've spent most of the last couple of days crawling through
the PDFs for client and server side AS, along with the technotes
and samples, attempting to get a clear understanding of how to get
SMIL XML based dynamic bandwidth streaming from FMS2. I've been
able to code from scratch a nice NetStream based solution, but
really want to use the dynamic bandwidth management and loose
coupling of the SMIL based solution. Currently I've got the
following setup:
Windows 2003 Server
IIS 6
serving a swf containg the following button which dynamically loads the smil file from the same directory as the swf:
on( click ){
import mx.video.*;
_root.vid_ctrl.contentPath = " http://localhost/flashVid/streams.xml";
trace( "contentPath: "+ _root.vid_ctrl.contentPath );
var listenerObject:Object = new Object();
listenerObject.metadataReceived = function(eventObject:Object):Void {
_root.vid_ctrl.setSize(vid_ctrl.preferredWidth, vid_ctrl.preferredHeight);
_root.vid_ctrl.seek(4);
trace( "contentPath after metadata: "+ _root.vid_ctrl.contentPath );
}
_root.vid_ctrl.addEventListener("metadataReceived", listenerObject);
}

This is the content of the XML SMIL file:
<smil>
<head>
<meta base="rtmp://localhost/bls_videos/_definst_" />
<layout>
<root-layout width="320" height="256" />
</layout>
</head>
<body>
<switch>
<video src="Bag-mask 1 resc (512)" system-bitrate="512000" />
<video src="Bag-mask 2 resc (512)" system-bitrate="128000" />
</switch>
</body>
</smil>
I can see in my server log for the bls_videos app that a connection is being made, but no streams are showing on the streams tab, and no response on the client. The following is logged on server when the connection is made:
welcome[object Client]
Error : command msg sent before client connection has been accepted.
Error : command msg sent before client connection has been accepted.
The Welcome is a trace line I put into the main.asc to ensure it was getting called. Not sure what the error is about.
Any more detailed information on using the SMIL XML files for streaming - particularly a fully worked end to end example, would be useful.After trawling through the various online and offline docs on this subject there is very little to guide anyone.
thanks
