Network problem in JMF project of video conference
hello,
i am working on video conferencing tool project. We are using a server-client architecture, but for
voice chat or Video chat or Video conferencing we are using peer 2 peer connection.
We developed this in Java Media Framework.
Now when we use this tool in internet we are getting problem.
Like we tested it from USA to India, at that time it works fine but when we use it from Germany to
India or vice versa then some times only voice comes (in video chat)but video doesn't.and also video start for few moments then it disappear.Many times nothing comes whether it is voice/video chat.when we see in the media properties the stream it gives zero in JMF player window.
I need a help on these :
1. What can be the reason for some times video chat work and many times it doesn't.
2. Is NAT etc need to implement.
3. P2P is reliable or not , i also heard about JXTA, can we use it with JMF(for internet and intranet version).
Please help me out. If need more information on question then let me know.
Looking forward for reply.
Thank you
hi,
I changed the TTL in SessionAddress of destination address to 255, but still i am not getting any voice or video data. AVReceive2 is still saying "Waiting for RTP data reply.." in almost cases.
When i send text data message (through TCP connection via server) it reaches well, but when i send voice/video data through UDP data (P2P connection) it doesn't reach.
I checked with Wireshark packet sniffer tool, and i found that other side person has private IP address and the destination port is opened on his public server.
In more clear way :
My IP Address is public IP Address say PUBLIC_IP_1 and also server is running on my system.
Other person's IP address is some private IP address( the person is staying in country) and the Server address ( i think, to which he is connected) is some public IP address say PUBLIC_IP_2. I am sure about that because i asked him his ip address by ipconfig command on his system which has given private ip address.
So when we start the voice/video chat session the RTP session becomes as rtp://<*PUBLIC_IP_1*>:21020 according to type of data and i set the TTL as 255 for destination IP address(which is given as PUBLIC_IP_2 in program).
Now when we see the packet transmission and receiving operation, packet reaches from My PUBLIC_IP_1 to PUBLIC_IP_2 at port number 21020 ( suppose voice session)but no pakcet from other side that is PUBLIC_IP_2 from port 21026.
NOTE : _21020 is target client's receiving port and 21026 is my receiving port._
I am not able to understand the condition because in one of our session out of 10-15 tries , we got voice stream from other side but no video stream in video chat session. At same time other person is not getting any stream.
So is it a some network issue? because in jmf we have to give ip address of the target system for RTP transmission.*
Please help me if there is some other way to do it.
Please help me out, what should i do to solve this problem.

Video Conference with a Windows PC
I have an iMac G5 with a separate iSight camera and my daughter has an iBook G4 with separate iSight camera. My son has a Windows PC with the following: Intel Extreme edition qx6700 quad core processor, 2 GB of ram and a BFG 8800 GTX video card. He is running a dual boot system with XP SP2/Vista. His camera is a MS Lifecam VX-3000. All of his drivers are up to date and he is using AIM with Trillian to communicate with his sister and me.
Our problem is that I can video conference with my daughter and a third person and my daughter can video conference with me and a third person, but my daughter and I can not video conference with my son. We can each individually iChat with my son, but video conferencing is not possible with him. Both my daughter and I have multiple iChat camera icons for each other when we launch iChat, but my son shows up with one iChat camera icon when he is online.
Is there something that can be done on his PC hardware or software wise where we can video conference with him? Or is this a problem with all PCs? Any help in figuring this out would be much appreciated! Thanks for your help.

Your son has a single camera icon because he is unable to participate in multi-way chats (macs only).
Get your son to check his windowa firewall and other settings:

If that doesn't solve your problem, consider Skype instead. In my experience, Skype is a better bet for Mac-PC videochats.
Both sides will need to download the appropriate version of Skype:

Problem using iPad2 to project streaming video to a screen
Sounds old fashioned, but we use a projector and big screen to watch movies in the living room on family movie night. Up until last week I could hook up the iPad to the projector, rent or buy a movie on Amazon, and project it with no problem. When I attempted it last weekend the sound and closed captioning came through, but no picture. We could watch the movie on iPad alone, but not when hooked through the projector. This was prior to updated iOS to 8.3. We can still project videos from YouTube so I know it isn't my projector. At one time I could also project streaming video from Netflix, but that stopped as well the end of last year. Can anyone tell me whats going on?? Is there something I can do to regain the ability to project videos again?

enableComponents(false);
buttonStart.setLabel("Pause");
buttonEnd.setEnabled(true);
startMonitoring();
try {
processor.start();
DataSource clone = Manager.createCloneableDataSource(datasource);
MediaLocator ml2 = new MediaLocator("file://capture.mov");
System.out.println("Content Type " + clone.getContentType());
datasink = Manager.createDataSink(processor.getDataOutput(), ml2);
datasink.open();

IChat AV 3.1.1 (v429) Video Conference Problem :(
Hello everyone,
I have a problem with iChat and I hope you can help me guys. I don't know what to do, I never had this problem before. When I start an video conference I can see myself, the picture is kinda blur though..I can't see the person I am having the video conference with and the other way around..can anyone tell me what's wrong. My iChat was working fine a couple of days ago and all of the sudden it stopped working..
I re-installed ichat and the problem still persists.
I changed my quick time streaming settings to 1.5 Mbps..and it's still not working..
Please can anyone help me to solve this problem??
Thanks in advance,
StuartHi everyone ,
how are you doing? Thanks for your help Defcom(UK) ,that was the missing piece of my puzzle. If you were here I'd give you a big kiss. Well, maybe not.. I think a hug would do just as good.
Fortunately, I noticed the problem right after installing iGlasses, so I was able to figure out the problem immediately. I deinstalled iGlasses, unfortunately deinstallation of iGlasses won't fix it either. What you have to do is deinstall iChat and remove all preferences,logs & iChat folders. The best and easiest way to do it, is to use an application like cleanapp, you can find more information on cleanapp at http://synium.de/cleanapp/index.html .
So after you have wiped off iChat completele with all files and settings from your system, download iChat or reinstalled it from your Mac Os X Tiger dvd. And here is the very important part, after you have installed iChat again usually it should work but in case your problem still persits, you should do what Defcon(UK) suggested.. you need to apply the Intel Combo update..so your iChat messenger is upto date..Voilà tout..the problem is solved..
Thank you once again for your help Defcom(UK) ..
Have a nice day..
Kind Regards,
Stu

I just bought a MacBook, and I am having problems connecting to others via the iSight. I got it to work with my roommate's computer, but I mainly want it to work on my fiancee's. I have Tiger, and she has Windows XP. I searched and searched and opened up the ports everyone seems to suggest. My router is a Linksys (of which the model I don't know). I suspect it could be a problem on her side, but it doesn't work with my friend's computer either. Sometimes it tells me I didn't respond (?), what do I do? I don't want a wasted iSight.
oh yes, here is the error report:

IChat video conference connection problem
I am having trouble connecting in a video conference. I get to starting connection then it just hangs, or it will say that I did not respond. I have a netgear router which I know causes problems but i opened up every possible port that iChat uses. I am using a webcam supported by ichat, my video comes up fine
Hi,
This page is for how to Access and to view only.
It shows UPnP.
Make sure it is enabled and the setting saved.
Repeat. (Enable it again and save) as setting it twice on some firmware seems to make a difference.
This will allow the ports to be open when the Application wants them.
Make sure there si nothing set in the Port Forwarding section.

Ichat video conference problem
hello i am having a video conference problems when i try either the quailty is bad or the person that i am tryin to view camera is very blurry to the point i cant tell what it is has anyone has this problem or know how to fix it thanks
Which camera are you using? I have a MacAlly USB webcam. Before I bought it I went to their site to see what problems people were having.
Some of the problems people were having with blurry video was because they didn’t remove the protective clear tape over the lens or they didn’t know how to focus the camera, which on the MacAlly is turning the ring around the lens.
Maybe yours is a more technical problem, but this information helped me to not make the same mistakes. -
Audio&video conference network deployment
HI guys. I am new in conferencing so apologies if u guys think my question is stupid . There is voice and data network and we need to install Biamp conference system which need connection to voice net for voice traffic and to data network for video traffic . What is the good practice :
a) to create separate vlan for conference on the core switch which will do routing for both data and voice traffic?
OR
b) use separate physical connections to voice vlan and data vlan (that mean need ip from data and ip from voice to be configured on conference system) ?
thank you .Hi Bekzod,
Since the same node is processing both audio and data portion of the conference, you will have only one IP for the server. Hence, what we've seen is all the conferencing is kept on the same VLAN. You can later on regulate the priority of packets on the network with QoS.
I hope this helps.

Audio Video Conference application with JMF
hi there!
I am developing an "Audio Video Conference application". so far I've been able to develop an applicaiton which opens an RTP Player on the client side, now my purpose is to enhance the functionality of RTP player by adding various functions like "Quit", "Pause" etc. I am looking for more options for enhancing the functionality of the RTP player in order to make it more user friendly for example I've been able to find the method for quiting from the player which is "KillThePlayer()" it is found in the class "PlayerWindow".
java.lang.Object
|
--java.awt.Component
|
--java.awt.Container
|
--java.awt.Window
|
--java.awt.Frame
|
--com.sun.media.ui.PlayerWindow
|
--RTPPlayerWindow
Please suggest me some of the classes and methods where I can find the method(s) for "Pausing the player" by which the player stops recieveing data and when un-paused it again starts recieveing, and also suggest me more functions to add to the RTP player so as to make it more user friendly.hi!
thanx, I appreciate your interest! i know i am hitting the wrong forum but i have also posted my query in the JMF forum, i waited for long but unfortunately there was no reply posted to my request, so i just thought why not to try on some other relevant forums.
if there is any sort of refernce available to my topic please help me.
thanx for your help,
bbye! -
I capture a video but can't save it .How to halndle the problem via JMF?
Hi everyone, I'm starting to use JMF and faced the problem
The problem is to save captured video in .avi or .mov formats.I managed to capture and play it in a player, but can't save it .On the other hand when I used processor to capture and save the video , I've succeeded .But my task is to combine these two actions. Give a hint please.
All kind of replies will be greatly appreciated.

You need to get the StreamWriterControl on the DataSink, rather than the Processor.I doesn't seem to work.

Live video conference over internet
hi frndz,
i have done a video conference application which works fine in LAN.
i have a static IP server to host the video conference application.
my problem is that i was not able to recieve the video transmitted from the server. in vise-versa if i send it from client which is in different network, i am able to recieve it frm the server using the public IP of my ISP,
can any one help me how to transmit in rtp:// from server and how to recieve it in the client side
i have checked this transimission and receiving by JMF studio and my code
rgds
-venkathi,
first get clear idea on JMF archietecture and wot it does,
Start with creating a player,
learn about processors, DataSource, realizing a player, media types supported by JMF and RTP protocol,
by learning above things u ll be clear about how to start ur video conference app,
for further clarification revert me back

How can I tell that AutoQOS config is adequate on a video conference switch
I have a Tandberg video conference bridge and gateway connected to a 3750 switch. The audio is marked EF and the video CS3. I configured AutoQos on the switch and trust DSCP on the ports. When we reach a large video conference of 25 or more attendies, we begin to have problems. The Tandberg starts to ratchet some of the video streams down, some to below 180kps, and the conference quality begins to suffer.
The only change to the default AutoQOS config I've made is changing the "mls qos trust dscp" on the uplinks, adding a QOS policy on the Tandberg ports to mark the video with CS3 and trust the audio DSCP (Tandberg had a bug that didn't mark the video packets) and adding
queue-set 2
priority-queue out
to the uplinks.
Will the default AutoQOS queue/buffer/SRR share and shape commands be adequate for 25 to 30 simultaneous video streams? We allow about 500k per stream.
I read through the 3750 QOS guide, but am a bit confused with the explanations of the queuing and SRR workings. I know that CS3 is mapped to COS-3, but don't know which queue it goes in and whether or not it gets shaped/disgarded when too much video is present.
Once I am sure that the 3750 QOS is working OK, and not causing problems with our large conference calls, then I'll expand my troubleshooting to the rest of the network.
I've attached a text file with the 3750 config, and 'show mls qos int statistics' that show the packets are being marked.I mistyped in my first post. I do indeed mark the video as AF41 (Cos4). It is the call control that I mark CS3 with the policy map to get around the old Tandberg bug that doesn't mark the call control.
So do you think the queue 3, where Cos4 goes to, is big enough to handle 30 video streams of 480k? If my calculation is correct that would be 14.4mbps of video on a 100mbps port.
With this config.....
srr-queue bandwidth share 10 10 60 20
srr-queue bandwidth shape 10 0 0 0
...is it telling me that queues 1 & 2 get 10% bw, queue 3 gets 60% and queue 4 gets 20% bw and is shared? If that is correct than 60% is more than enough for 14.4mbps of video.
What happens if too much video overruns the queue? -
IChat video conference question?
I have a couple of and maybe some dumb questions.
I manage a small office with 3 Dell desktop windows XP Pro computers and 2 Macs (1-iMac 1000GHz & 1-Powerbook G4 1000GHz, both 10.4.8) and one Savin Office scanner/copy machine. The one Windows XP computer works as the server for the Savin copier. All are assigned static IP addresses. I'm presently running a Linksys wireless router WRT54G. We have several other seperate locations associated with the business where we would like to be able to video conference with iChat.
I use to be able to iChat (video & audio) with the office computers for about a year and a half from my office but after changing the Linksys router from an older non-wireless version to the newer wireless version WRT-54G vers. 5, I can no longer Video or Audio iChat with the office on either of the 2 Macs listed above (text chating is no problem). The 2 office computers can no longer Video or Audio iChat with any other locations any where (but they can within the office, machine to machine). After exhaustive research, I'm convinced it is the Router.
I was thinking of getting the new Airport Extreme base station with N, that Apple is now advertising, to see if this works. My first question is, will it work with the Savin Office copier/scanner like the Linksys does? Is it any different in setting up than say the Linksys?
Is this more of a HOME piece of equipment or can I really use it in an office setting that is truely cross platform. (all computers file share with each other, particularly with the one XP machine that is the server for the Savin scanner.)
Will I have any problems at all with iChat.
I know there are a lot of questions but I really don't want to spend the money and disrupt the office if there is any anticipation of problems.
The business is a Day Care Center with 9 locations so the Video & Audio chat is important to the kids and the office personnel.
If this will work flawlessly, I would go ahead and replace the 10 routers for the 10 different centers we have, so everyone can Video & Audio iChat.
Thanks for your help.

Might it be that you just don't have the proper ports opened on the Linksys router to allow for both the audio & video portions of iChat? The following site is a great tool in setting up ports for specific routers, including your Linksys: http://portforward.com/default.htm

I am assuming that your Savin copier is Ethernet-enabled. Since the new AirPort Extreme Base Station (AEBS) provides three Ethernet LAN ports, it should function similiarly to the Linksys to provide network access to the Savin. Since it a different device, there will be differences on setup. For example, the previous AirPort base station relied on the AirPort utilities for setup...and not a web-based one like the Linksys do. This is expected to be the same for the new model.
Is this more of a HOME piece of equipment or can I really use it in an office setting that is truely cross platform. (all computers file share with each other, particularly with the one XP machine that is the server for the Savin scanner.)
I would treat the AEBS no different than your current Linksys. Would you consider the Linksys a "HOME" piece of equipment? The AEBS should fit in quite well in a business environment as it does in a home one.
Will I have any problems at all with iChat.
As long as you have the proper ports opened on BOTH your hardware AND software firewalls, should shoudn't have any problems with iChat.
