Adobe Access is agnostic to the delivery mechanism of the
content as the Flash Player abstracts out the networking layer and
simply provides the protected content to the Adobe Access subsystem.
Hence, content can be delivered through HTTP, HTTP Dynamic Streaming,
RTMP, or RTMPE.
However, you may get some issues due to the necessity of the
protected content’s metadata (usually in the form of a ‘.metadata’
file) before Adobe Access can acquire a license to decrypt the content.
Specifically, with the RTMP/RTMPE protocol, only FLV and F4V data
can be delivered to the client through the Flash Media Server (FMS).
Because of this, the client must retrieve the metadata blob by other
ways. One option to solve this problem is to host the metadata on
an HTTP web server, and implement the client video player to retrieve
the appropriate metadata, depending on the content being played
back.
private function getMetadata():void{
extrapolated-path-to-metadata = "http://metadatas.mywebserver.com/" + videoname;
var urlRequest : URLRequest = new URLRequest(extrapolated-path-to-the-metadata + ".metadata");
var urlStream : URLStream = new URLStream();
urlStream.addEventListener(Event.COMPLETE, handleMetadata);
urlStream.addEventListener(IOErrorEvent.NETWORK_ERROR, handleIOError);
urlStream.addEventListener(IOErrorEvent.IO_ERROR, handleIOError);
urlStream.addEventListener(IOErrorEvent.VERIFY_ERROR, handleIOError);
try{
urlStream.load(urlRequest);
}catch(se:SecurityError){
videoLog.text += se.toString() + "\n";
}catch(e:Error){
videoLog.text += e.toString() + "\n";
}
}
