This is a topic that's been discussed many times on this list - if you delve into the archives you'll find lots of suggestions about how to go about creating this sort of application, along with some of the possible shortcomings/problems/issues etc.

Hi,
We have one that we are testing right now. Hopefully, we are able to release it end of next week. Essentially, what we have is an applet that takes snapshots of the desktop, sends the images to Red5, have xuggler convert them to video that gets streamed to the flash client. If you are interested in the code, you can find it here http://code.google.com/p/bigbluebutton/source/browse/#svn/trunk Take a look at deskshare-applet, deskshare-app, and bigbluebutton-client.

Is there a reason you didn't choose to encode directly on the client to screencodec and then stream this to Red5? I'd imagine time was the reason.

The reason was the size the applet would become if it had to do the encoding. Xuggler and ffmpeg together are rather large. In contrast the size of the applet now is just a few kb.
There are also issues when using Xuggler inside of Applets. - Denis On Fri, Jul 3, 2009 at 1:10 PM, Dominick Accattato <dominick@...> wrote: Richard: _______________________________________________ Red5 mailing list Red5@... http://osflash.org/mailman/listinfo/red5_osflash.org |

Speaking of which, if anyone is an Java web-start expert or applet expert contact us on the xuggler list -- we're interested (for Xuggler 4, not sooner) in making Xuggler work with web-start, but we need some guidance We've never built a JNLP-project before, and Xuggler has some, um, special, needs :)

Interesting, although I'm talking about encoding directly through code, not using a third party.

the size of adding an api for encoding into ScreenCodec is worth the benefits from bandwidth performance. I'd imagine your currently sending an image sequence, as compared to deltas which would be sent with ScreenCodec.

We haven't looked into that..or don't really have any idea how it can done.
Perhaps if you can provide any pointers or ideas we may be able to take a look at it in the future. However, the way it is now works fine... What you're proposing is attractive because we don't have to worry about tunneling because we can just use RTMPT. Right now, the applet connects to port 1026 and we are trying to figure out how to make it work through http tunneling. The "vieweing" part works using RTMPT.

Yes, the applet is sending image sequences to Red5.
Forgive me for my ignorance, but what's the ScreenCodec? Can you point us to where we may be able to read about it? Did a quick google. Results point to WMV 9 ScreenCodec and VH ScreenCodec. One results talks about in the SWF file format (http://www.wowzamedia.com/forums/showthread.php?t=732). Is this what you mean? Thanks.

Yes it is.
http://code.google.com/p/bigbluebutton/source/browse/#svn/trunk/deskshare-applet Just to be clear...the applet is not a Red5 client in the sense that it uses RTMP to talk to Red5. We tried using the RTMPClient class in Red5 but the applet became too big because of dependencies to other libraries.
