Remoting a facility by which a client can call a server method in a request response fashion. Unlike RTMP remoting services are performed using AMF over HTTP/HTTPS. Red5 can act as both a RTMP server as well as a HTTP/HTTPS remoting server. Remoting enables non rtmp clients to access Red5 methods. A very practical approach would be to request chat room user count for example. Using remoting you can request such data without consuming too much server resources as in a RTMP connection. You can also create chat programs with simple amf-polling as well. Remoting also lets you sync data types over both ends (client-server) (more…)
Record Live Stream With Red5 Media Server
Most commonly known modes of working in RTMP servers are the live, record and append modes. However a most commonly required mode which is not provided in the flash API is the Live-Record mode. Each RTMP server has its own way of implementing it on the server side. Here we will see how to use flash client and Red5 to do live-record.
Red5 Server Application Code: – [ Goes into Application Class ]
/** {@inheritDoc} */
@Override
public boolean connect(IConnection conn, IScope scope, Object[] params) {
return true;
}
/** {@inheritDoc} */
@Override
public void disconnect(IConnection conn, IScope scope) {
super.disconnect(conn, scope);
}
@Override
public void streamPublishStart(IBroadcastStream stream)
{
try {
stream.saveAs(stream.getPublishedName(), false);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void streamBroadcastClose(IBroadcastStream stream)
{
System.out.print("Broadcast Closed");
}
@Override
public void streamBroadcastStart(IBroadcastStream stream)
{
System.out.print("Broadcast Started");
}
@Override
public boolean connect(IConnection conn, IScope scope, Object[] params) {
return true;
}
/** {@inheritDoc} */
@Override
public void disconnect(IConnection conn, IScope scope) {
super.disconnect(conn, scope);
}
@Override
public void streamPublishStart(IBroadcastStream stream)
{
try {
stream.saveAs(stream.getPublishedName(), false);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void streamBroadcastClose(IBroadcastStream stream)
{
System.out.print("Broadcast Closed");
}
@Override
public void streamBroadcastStart(IBroadcastStream stream)
{
System.out.print("Broadcast Started");
}
In the above code you will see there are two events for handling BroadcastStart: streamBroadcastStart and streamPublishStart. We will typically use streamPublishStart which is safer. The method saveAs takes two parameters: savefilename and append. When append is true Red5 will try to append new stream data to existing file , in which case it may throw exception if file was not existing. Thus we surround the statement by a try… catch block to handle such situations.
Flash Client Sample:
In your flash client code you create a simple publisher and publish the stream as live stream. Red5 will automatically begin recording the stream at server end.

You will notice that in the above code we stream cam/mic data in live mode. And our server side code captures the live broadcast into a flv container.

Open source video revolution – OSMF on Red5
JWFLV Player vs Flow Player vs Strobe:
Strobe Player:
Note that in some cases flash player may ask you to accept ssl certificate. this happens only with red5 running the OSMF player
OSMF is a move by Adobe which clarifies how much flash is towards openness. Whether your needs are to setup a video-tube site or live event broadcasting, OSMF and Red5 provide the perfect package to go fully open source. No more cumbersome domain licenses. No more expensive RTMP solutions. Take up Red5 , download Adobe strobe playback component and go live – completely open source. (more…)
