Video Conferencing using java

hi,
i am developing video conferencing project using JMF.
and using AVReceive2 and AVTransmit2.
i am able to send and receive audio and video between two pc's where one transmits and one receives.
but how to use AVReceive2 and AVTransmit2 for more than two pc's when any one doesnot have information that other user is transmitting.
What i mean is that when one user wants to connect to another user then how can second (receiver) know that someone is sending him data.
Basically when to run the AVReceive2 program on second PC..

Video conferencing using RTP

IM doing my final project in video conferencing...
i want know how to send video and audio sametime by live capture..
if we use vfw://0 it is for live video
r dsound://0 for live audio
what is the command for sending both the items

I am doing the project with user interface,OK ,most people do...
So we will be giving the address at start of inititalisation.whats the problem in this, you would have to save that address in some variable....
we will not be able to type the command once the project is opened.What?? which command?
we will be locating the medias by getting the commands like vfw://0 (for video) and dsound://(for audio) in a text box.
Likewise how can we get the live audio and video simultaneously??the method is already explained in Reply#2, what is the problem with that?
I like to know whether these commands will work for transmitting both
vfw://0&dsound://0
vfw://&dsound://0
dsound://0&vfw://0No... if you think that is what JMStudio shows you, it is lying ;-)... you can't even merge the two Datasources together and make a processor to transmit them, it has always failed (thats my experience). You just have to create 2 processors, one for video, one for audio and similarly two RTPManager instances (with same target and source ip addresses but different ports) and then when you say start transmission (by clicking a button or something) you have to start the processors and output streams from the RTPManager, thats all.... at the receiver side, you just have to make a player with the rtp address given in Reply#2 and start the player.
Thanks!

Does Video Conferencing use multicast?

We want to enable vide conferencing between multiple remote sites, however, our providers backbone does not support multicast traffic.
The question I have is if I have 2 users in Boston, 2 in NYC and 2 in SF for video conferencing, is the traffic output from a MCU a multicast or unicast to the remote sites?
This is with the MCU at the NYC location.

H.323 uses unicast traffic. Some vtc endpoints are also capavle of generation a mutlicats video stream, but that is not a part of the H.323 feature set. Multicast is not supported on the public internet, and very few if any providers are going to allow it on their backbone.

Trying to bypass CAC for Video Conferencing using EnableBWPolicyOverride

Scenario:
CAC enabled and bandwith policy defined for all company sites. Video bandwidth very restricted (250 Kbps).
VIP users were granted a Voice Policy with EnableBWPolicyOverride=TRUE (VIP users must bypass CAC).
Test:
P2P Video Calls between VIP users bypass CAC, allowing high video resolutions (Ok!).
Video Conferences between VIP users don't bypass CAC, limiting video to low resolution (NOT ok).
Is this expected, that Video Conferencing will not respect the EnableBWPolicyOverride=TRUE from the Voice Policy? (I know, it's a VOICE Policy and I'm tlaking about VIDEO. But remember, on P2P video call the bypass worked.
Any ideas?

Hi,
Bandwidth policy override enables administrators to override call admission control policy decisions for a particular user, however, the policy will be overridden only for incoming calls to the user and not for outgoing calls that are placed by
the user. So I think the policy does not apply to video conference.

Risks when using DV camcorder for ichat video conferencing..

I have a sony dcr pc350. Bought it January of this year and havent had problems with it until recently. For some reason, the video head was damaged. When i play my DV tapes on it, thick gray horizontal lines appear, or sometimes it refuses to play the tapes completely. I just recently read one of the topics in the ichat AV FAQ and it mentioned that there's a risk that using a DV camcorder for ichat AV video conferencing can actually damage the camcorder. Now i'm wondering if that's the reason why my dv cam is damaged now. I haven't been using it to shoot some video footage for a while now, but i have been using it to video conference very often for about over a month now. And then recently, when i had to use it to shoot some video, that's when i saw that the camera needed repairs. As i've mentioned, I havent been using it for anything else (not even to shoot video) and i havent dropped it or anything. I pretty much take good care of it. So i'm thinking that it was my constant use of it for video conferencing that did the damage.
So my question is:
Has anyone else experienced some camcorder damage that might be related to frequent video conferencing use? If it does indeed damage the camcorder, what specifically does it do to it (what does it damage, how exactly does it cause the damage, etc...)? I'd like to know so I can be more specific when I bring it to the service shop for repairs.

Hello Albert,
I do NOT think that using your Sony with iChat AV poses any greater risk than using it for other things.
I used my Sonys (DCR-TRV17 and DCR-TRV70) for a while, but I switched to iSight before I damaged them. (I am clumsy.)
The kinds of damage I contemplated in the iSight vs Camcorder or other web-cam FAQ were:
- dropping or tipping the camera or the tripod upon which it was mounted,
- contamination from dirt, body oils, or dust, etc.,
- wear on the heads and internal moving components, and
- wear on the camera's electrical connections.
Moreover, regular professional clean and adjust is required for my Sonys based on usage hours. Such is NOT required for iSight.
Some of those risks can be mitigated by careful placement and use and by keeping the tape out when using the camera, but some risk always exists when using the equipment. My thought was that, if I wore out or damaged a camera by using it for hundreds of hours of video chat, I would rather wear out or damage iSight, which is cheaper than my Sonys were.
Please post back what your Sony Service Tech finds. I will be eager to read whether your camera needed more than a professional clean and adjust.

I think, I got your point.
You are saying that Java Web Start are using to install client applications remotely. Am I right?Basically, yes.
and these applications can be developed in AWT/Swing or Applet.Yes.
But my concern is different.
I need a web application, that means application will be running on the web server and more than 1 clients will access this via the http URL. ..This is equally easy for either an embedded applet or an app. launched using JWS. So long as the server-side component of the teleconferencing is at the same site that served the app., either can access it while in a sand-box. If the server-side component is at a different site, either type would need to be digitally signed, and trusted.
..I don't have to install the application to each client separately. .. OK - not for the server-side component, but for the client-side component, it sure does need to be installed if it is either an embedded applet or a JWS app. The only real difference is that for some people, downloading an applet is not seen as 'installing' software, though in reality it is. An applet must be cached on the client-side before the code is invoked to make the applet appear in the web page. Where JWS provides a better user experience than applets though, is that the browser (and JRE) cache might be cleared (effectively 'uninstalling' the applet), by things outside Java's control (such as the user clearing the browser's cache using the browser's own controls).
..so I need the video and audio conferencing in this application itselt. it will be like a website.
so please tell me, what I have to do?I am still not convinced that this needs to be, or will provide a better user experience as, an applet. But let's put that thought aside for the moment.
Can you do this video conferencing using the cross-platform version of the JMF? The cross-platform version of JMF does not support as many formats(1) as the JMF performance pack - and you might find that the PP version supports some formats that offer better compression than the x-plat version is able to handle. Note that this can be tested once you have the server-side component in place - it is pretty much the same for an applet, JWS app., or plain old desktop app. such as JMStudio (provided as a sample app. with JMF) to access the web service that provides the video feed.
