Hi all

Does anyone know how to create a script of some kind to grab a still picture from a live stream and save it as a JPG file?

In this way a cron job can tricker the script and thereby grab a picture fx every 10'th minute and the picture can be shown on a website so people that are not attending can have a look into what is happening in the live stream.

Can anyone help?

Thank you both :-)

Isn't there a more easy way? I just need to grab one screenshot from a stream and save it in my webspace (so it can be used at my website).

You would require to send the data as data message by calling ns.send from publishing client and the subscribing side will have to implement function to recieve it and process it..

Something like that

The sending client has the following script:

var my_nc:NetConnection = new NetConnection();
my_nc.connect("rtmp://myServer.myDomain.com/appName/appInstance");
var my_ns:NetStream = new NetStream(my_nc);
my_ns.publish("slav", "live"); 
my_ns.send("Fun", "this is a test");    //Fun is the handler name.

The receiving client's script looks something like this:

var my_nc:NetConnection = new NetConnection(); 
my_nc.connect("rtmp://myServer.myDomain.com/appName"); 
my_ns = new NetStream(my_nc); my_ns.play("slav", -1, -1); 
 my_ns.Fun = function(str) { //Fun is the handler name. trace (str); }

In the example above, you can send jpeg data as parameter of function "Fun"

Or you may choose metadata to send such data.. More info @ http://livedocs.adobe.com/flashmediaserver/3.0/hpdocs/help.html?content=00000190.html
