Tobias,
Yes this is possible with Red5 and OpenLaszlo. Go to this wiki
page<http://wiki.openlaszlo.org/RtmpRed5Webapp>and try the example
war. This page also outlines some bugs in OpenLaszlo
that need fixing in order to support Red5 fully, but it has been working
fine for server - client communication.
Here is an example open laszlo file:
<canvas debug="true">
<button name="callButton" onclick="sendEventCall();">
Call sendEvent
<method name="sendEventCall">
canvas.rtmp.sendEvent.event = "button was clicked!";
canvas.rtmp.sendEvent.call();
</method>
</button>
<rtmpconnection name="rtmp" debug="true" autoconnect="true"
src="rtmpt://192.168.1.134:80/cardsrvr/myhome' }" >
<handler name="onconnect">
Debug.write("connected");
</handler>
<handler name="onerror">
Debug.write("error ",this.status);
</handler>
<netremotecall name="sendEvent" funcname="sendEvent">
<attribute name="event" value="" type="string" />
<netparam name="vars1"><method name="getValue"> return
parent.event;</method></netparam>
</netremotecall>
<netremotecall name="newEvent" funcname="newEvent">
<method name="onResult" args="value">
Debug.write('event received: ' + value);
</method>
</netremotecall>
</rtmpconnection>
</canvas>
This will connect to a red5 rtmpt (http tunneling) connection with the
rtmpconnection tag. Then when the button is clicked
the netremotecall tag named "sendEvent" is used to call the server's
endpoint. The ApplicationAdapter class which is the
server handler for a particular context is used to call into (from client -
server) and call out of (server - client).
public class Application extends ApplicationAdapter implements
IPendingServiceCallback {
private static final Log log = LogFactory.getLog(Application.class);
public boolean appStart() {
log.info("Application.appStart");
return true;
}
public void appStop() {
log.info("Application.appStop");
}
public boolean appConnect(IConnection conn, Object[] params) {
log.info("Application.appConnect " + conn.getClient
().getId());
return true;
}
public void appDisconnect(IConnection conn, Object[] params) {
log.info("Application.appDisconnect " + conn.getClient
().getId());
}
public String sendEvent(String event) {
try {
log.info("Method 'sendEvent' called with: " +
event);
IConnection current = Red5.getConnectionLocal();
Iterator<IConnection> it = current.getScope
().getConnections();
while (it.hasNext()) {
IConnection cons = it.next();
if (cons instanceof
IServiceCapableConnection) {
((IServiceCapableConnection)
cons).invoke("newEvent", new Object[] { event }, this);
}
}
} catch (Exception err) {
log.error("invokeClientFunctions", err);
}
return event;
}
public void resultReceived(IPendingServiceCall call) {
try {
log.info("resultReceived "+call);
log.info("resultReceived Arguments "+call.getArguments());
log.info("resultReceived Arguments Number
"+call.getArguments().length);
log.info("resultReceived Result "+call.getResult());
log.info("resultReceived ServiceMethod Name
"+call.getServiceMethodName());
}
catch (Exception err) {
log.error("resultReceived",err);
}
}
Hope this helps. A good start would be to check out the example war.
