SERVER-SIDE ACTIONSCRIPT LANGUAGE REFERENCE FOR ADOBE MEDIA SERVER 5.0.1

Server-Side ActionScript Language Reference

Last updated 7/2/2013

Parameters

sourceStreamName A String. The name of the source multicast stream.

Returns

If a MulticastStreamIngest instance already exists for this group with this stream name, it returns the existing one,

otherwise it creates a new MulticastStreamIngest instance.

Example

The following example is pseudocode that provides a high-level description of how to ingest a multicast stream,

convert it into a Stream object, record it, and play it.

// First, set up Stream instance that will play (and record) the multicast ingest.

var stream = Stream.get("mp4:multicast-ingest.f4v");

// Next, set up a server-side NetConnection and NetGroup to join the Flash Group

// where the desired multicast stream is being published.

var nc = new NetConnection();

nc.onStatus = function(info) {

if (info.code == "NetConnection.Connect.Success") {

ng = new NetGroup(nc, groupspec);

ng.onStatus = ngStatusHandler;

}

};

nc.connect("rtmfp://<ams-introduction-server>...");

// Handle NetGroup status events; this simple example handles only the initial join.

function ngStatusHandler(info) {

if (info.code == "NetGroup.Connect.Success") {

// As soon as we've successfully joined the Group,

// attempt to start ingesting a multicast stream.

// Assume we know the stream name we want to ingest (sourceStreamName).

ingest = ng.getMulticastStreamIngest(sourceStreamName);

}

// At some later point (or directly in the ngStatusHandler above),

// play the multicast ingest.

stream.playFromGroup(ingest);

// The stream can be recorded locally.

stream.record();

...

stream.record(false); // And recording stopped.

// To stop playback of a multicast stream, pass the Boolean false.

stream.playFromGroup(false);
