Video Conferrence over Internet??

Hi all experienced JMF-ers,
I'm new to Java, of course JMF too .But I have a big will to learn it ..
I'm interested to develop such a video conferrence using JMF.
I've read JMF Guide ( although I don't understand all yet ), some refference, I learn several free source code on the internet ( it helps me to understanding JMF faster ) .
with my poor of experience I modify AVTransmit2 and AVReceive2 then I can make the code to transmit captured video and audio over LAN ( still one way stream ). Although it still makes a delay 1-2 sec.
But then when I look at this forum, I read several messages that video conferrence using JMF still have a problem such as can't transmit video stream over Internet yet.
Is there anyone who have solved this problem? ( I'm not testing yet for DaddyE's code for video conferrence) , if yes, I apreciated if you want to share ur depth experience about its high level architecture? And what's the algorithm ? I'll try to make the code by my self. Thanx before.
Regards,
Adhi

Hi khrisna,
i decide to make a conferrence over LAN first before it goes to internet.
It doesn't work yet. I modify the code AVTransmit2 and AVReceive2.
And I think I dont set the frame rate ( default from the web cam ).
Video and Audio encoding are set just like AVTransmit2.
I have a plan to make client-server transmit. In a Local Area Network,
I use socket network programming.
Now, I've a problem to clone datasource. I think someone in this forum has a problem as I have.
whats ur suggestion about these :
1. merge the datasource for audio and video capture first and then make it one processor. After processor has realized, cloned the dataOutput from processor, or
2. make a processor for each audio and video capture, after both processor has been realized then I merge the dataOuput from both. and then clone the mergedDataOutput.
which one can work better ? ur help,please!

Two EX90 devices can make video calls over Internet with No VCS-C and VCS-E

Dear Experts;
I have just started TelePresence and VCS 2 weeks before by going through cisco docs and videos and I had taken a risk of implementing the infrastructure elements.
We are now implementing Cisco Tele presence with VCS-C, VCS-E TMS,TCS,MCU and End points with Jabber in One setup.
and in another setup CUCM 10.5,UCCX 10.5 IM&P,Jabber with some 10 agents.
Now the question is In our same building in 2nd floor we have one EX90 and in 5th Floor one EX90 and over LAN we can make video calls using IP address.
In the same way is it possible to make a video call between 2 EX90 devices present in different location in the same city over Internet without the involvement of VCS-C and VCS-E.
Appreciate your valuable reply.
Regards
Debashis

The simple answer to that is NO! Where is the EX90 registered to at the moment? Is it on the VCS? or CUCM

hi,
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 to control and display video from IP camera using ActiveX control over Internet.

Hello,
I need to control my IP cameras over the internet. I need to log into the cameras and then display the video. There's an ActiveX control registered on the computer and works fine with IE to access and control the cameras. Controlling the cameras using IE works fairly well, but there are some quirks that I'd like to eliminate by using my own custom code.
Has anyone created a vi that controls a Foscam FI8905W over the Internet? I’ve attempted, but I keep getting a catastrophic failure when I try to call ManagementConnect Method in the DVM_IPCam2 ActiveX Control Module V1.0. I'm not sure whether I need to establish an IP connection with the cameras first, or allow the ActiveX control to establish it for me.
Some example code would be greatly appreciated. Running LabVIEW 2011 on a Win7 32bit. Even some code used to control a similar device using ActiveX over Internet would be helpful.

I have an example vi for interfacing to the foscam activex.
I plan on using mouse click events within the activex window to trigger the PT function.
I only have the basic up/down/right/left directions and not the down-right/down-left/up-right/up-left in the enum. You can load the camera's web page and view the source to see the Java script code that uses the activex control. There are definitions for the other directions.
I had to mark the control as "Disabled" to keep click events from going to the activex control. If I double click the control, it goes full screen. If I then click on it to get out of full screen mode the video never returns or returns to the wrong spot in the VI.

Anyone used VisionNet system "designed to provide real-time streaming video feeds over the Internet"?

I'm a Mac user and we only have Macs at home. My son just started preschool, which offers a VisionNet system--"a state-of-the-art system of cameras, servers, and software designed to provide real-time streaming video feeds over the Internet." However, on the VisionNet FAQ page, it specifies the following:
"You need a web browser that is Java-enabled, perferably Microsoft Internet Explorer. If you're running Microsoft Internet Explorer, it needs to be version 6.x or higher. We recommend Internet Explorer 6.x as this is the latest and most up-to-date product release. Some Windows XP and Windows XP Professional users will have do download a Java runtime environment in order to use the VisionNet system if they have not done so already."
We don't have any PCs at home, so I tried to log in using my MacPro desktop, my old MacBook Pro and my new MBP. Basically, for the last 3 weeks I've managed to access the site only ONCE from my desktop and after the time-out session, I wasn't able to log on ever again (I just cannot enter any keys on the Username and Password fields at login). If I hit the Logon button from the FAQ page, I get an "Unauthorized Access" pop-up message: "This site may only be entered from an authorized web site! Please enter this site from your childcare provider's web site." When I enter "OK" I immediately get a pop-up menu "Confirm Dialog Preference. Prevent this page from creating additional dialogs" but I still can't enter any keys at login. It does nothing!
The "support guy" has NO knowledge of Macs, so I don't know where else to go. The fact that I had successfully logged on once makes me believe it's something I have to update/delete/add in my Preferences in Firefox (I've used Safari and Chrome with no success). I've also considered purchasing an inexpensive PC just for this lousy VisionNet system but I want to see if anyone has any ideas or advice.
Can anyone please help me? Thank you in advance!

Here is a link to the finished PSA at Vimeo. It is not an outstanding production or anything too special, but it is worth noting that while some of the stills were doctored in Photoshop, the entirety of the editing and motion graphics were done in Premiere CS6.02; and the timeline playback was RealTime thanks to the MPE Hardware Acceleration and a GTX 560 2GB.

Bad video quality on Atom over Internet, but not o...

I have an Asus netbook with a 1.66GHz Atom, 1GB DDR3, and XP. The video quality when in a call over the Internet is almost always bad, and Skype complains the computer is "slow". There is no virus scanner or any other garbage running that sucks up resources. I keep it lean.
So I tried using a different computer to make the call; an 8 year old Sempron laptop, also with XP and 2.2GHz or close to that. Video quality is great. So it's obviously a computer performance issue, right?
It gets stranger. I set up a video call between these two computers over my LAN (i.e. within the same house). Video quality is great on both.
The results have been similar over a span of a year or more, calling people in different parts of the country, and even dropping Wifi and using a cable.
So what causes Skype to think the computer is slow when video calling over the Internet, but not when calling another computer on the same LAN? I have a theory, but I'll hold that thought for right now.

I have been using iChat exclusively over WiFi (Airport Extreme) from my iMac, and via Ethernet and WiFi from my Powerbook. I have not had any quality issues when connecting in this manner. Connections within my local network from WiFi to WiFi, as well as to outside connections over Broadband have all been of very good quality. Now if I can just get it all working again following the upgrade to Leopard 10.5.1.
FYI: I have even used iChat AV on Tiger using DUN on my Treo650 (Sprint), which worked fine as well.

Facing Problems in Streaming Video over internet using FMS 3.5

I,am using FMS 3.5 to stream video over internet.This video will be a part of a website www.mywebsite.com . I have the webserver in my company. This webserver has the local LAN IP : 192.168.10.19 which is binded with a public internet ip 212.77.xx.xx .This website is hosted using IIS 6.0 on OS windows 2003 server with SP2
I created a swf name sample.swf from sample.flv file and gave it the rtmp address as follows:
rtmp://192.168.10.19/vod/_StreamingVideo_/sample.flv (where _StreamingVideo_ is the instance on the server, and 192.168.10.19 is the LAN IP of server) ,and it worked fine and every one within the local company network could see the streaming video. Now i tried to replace this local address with the public address and the address became as follows:
rtmp://212.77.xx.xx/vod/_StreamingVideo_/sample.flv
After giving this public IP in the rtmp address i,am getting a message "Failed to load Flv from the address rtmp://212.77.xx.xx/vod/_StreamingVideo_/sample.flv" and as as result the video is not streamed and it only shows the progress bar on the link
www.mywebsite.com/VideoStreaming/Sample.html without loading the video. I have also checked the ports 80,1935,1111 on the server and they are open. Is there any problem with my rtmp address with public IP or any other reason ??. Please help me out in this regard because im realy stuck here.

Adding to my previous post this is the XML output i get when i try to access the fms admin console from local ip address i.e http://192.168.10.19:1111/fms_adminConsole.htm
<?xml version="1.0" encoding="utf-8" ?>
- <result>
<level>error</level>
<code>NetConnection.Connect.Rejected</code>
<description>Admin user requires valid username and password.</description>
<timestamp>2/3/2010 8:26:08 AM</timestamp>
</result>
but when i try to access fms admin console through public ip (http://212.77.xx.xx:1111/fms_adminConsole.htm) then it gives me the following :
Internet Explorer cannot display the webpage.
Any more suggestions Jay (because really ur the only one helping me out in this so far) ??

VIDEO CONFERRENCE OPTIMATION !!! help..

Hi all,
I'm still developing my video conferrence project ( over LAN ). I've modified AVTranmit2 and AVReceive2 to be one application. And I want to manage little client-server application, so that each user can make a conferrence with other user (more than one). I've already done bout transmitting and receiving audio+video between two computer. But I'm not satisfied yet bout my application. I think it should be high speed communication, coz it runs on LAN. but my application run with a delay about 2-3 second. Is it normal? What is the effect of streaming format in speed of transmitting? Can anyone suggest me how to optimize this video conferrence application. Especially to decrease the delay. I will appreciated if you want to share ur experience using JMF.
regards,
Adhinxz

i make each client transform their webcam image to a jpg image that is sent to the webclient.
so i try to explain a bit better:
i wanted to create a video overseeing application and wanted to see the image of my webcam from an applet.
so, my applet connect me to the server i made at home.
the server notice it received a connection and then he do some:
ImageIO.write(stream, "jpg", streamSocketClient).
on the other side, the applet decode the jpg stream to an awt image and show it.
so i mean that RTP streams are converted to jpg streams sent to client which will convert it to awt image.
good luck

Video Chat over Dial-up Connection

Hi,
Is it possible to have a video chat over a dial-up connection? If it is, I'm interested to hear what is the experience like from anyone who has tried it. Is it acceptable? How about having 3 person AV conference, and one connection is dial-up?
I'm looking at buying an MacBook for my parents so they can chat and see the grandkids but they only have dial-up and getting broadband is not really an option since where they are it's still ridiculously expensive.
Thanks for your replies,
Alex

Hi,
Since I started with iChat in 2003 I have only ever seen one post about a successful iChat Video over Dial-Up.
As I recall it was from Britain to somewhere in Ireland and the Irish end was using IDSN at the time at about 66kbps and that it was late in the day.
The Minimum spec stated is for an Internet connection of 100kbps but iChat will give you an Error message when it detects a Bandwidth or Connection speed less than 50kbps.
Realistically this (above) was a fluke and the answer is NO.

How Smooth Should Flash Video Play over a 6Mbps DSL Connection?

Hello,
I am noticing a lot of stuttering on my Flash videos viewed over the internet, Win 7 64bit and IE 8, Opera & Chrome.
Here is a link to some tests - http://watchmymvp.com/Encoding%20Test/EncodingTest.htm
Please give some feedback on your playback experience if you would!
Some background:
I am a video producer who shoots, edits, encodes and manages a few websites. I am very familiar with bitrates and encoding.
The videos I am seeing stuttering on are created from HD content and were encoded in Adobe Media Encoder at a bitrate from 775kbps down to 400kbps. When I play these through my 6meg DSL connection there is a constant random stutter like the video is stuggling with a low buffer. This happens even after the download bar shows the entire video is downloaded.
So am I expecting too much from Flash video? Will it always be an "internet" experience and not smooth?
When I double-click the .swf files in Windows Explorer they play just fine, very smooth. Maybe a SWF Publishing setting?
The Flash player is the latest which was uninstalled and re-installed
Thanks!

Hello Vicente, thanks for your reply.
So the videos did not show stuttering when you watched them? Could I ask what your computer specs are? - Mac/PC, browser etc...
I get a random stutter which shows up more when there is camera movement.
I am trying to track down why this is happening when the .swf file played locally plays perfectly.
Since I an in the video industry, I would like these files to play as if they are on a television is that is possible.
Thanks for your input.

Audio and video cpompression over anetwork.

Hello every body,,
I want to transmit audio and vedio over internet,, and as every body know the transmition of audio and vedio has some delay over the internet...
so can i made some compression to audio and vedio streams at the sender side and then transmit them and extract this commpression at the receiver side..???

i dont think you can compress to a lower quality when sending and then decompress to a higer quality when receiving. actually, h263 and jpeg are already compressed. what you can do is just degrade the quality of a jpeg or h263 streams and receive it like that. the lowest one-way video stream bandwidth i could go down to w/o major programming was 80-90kbps with h263 codec. there's probably a way to make it even less, but it requires a deeper programming to reduce frame rate, because standard JMF ways to alter frame rate dont work (i've tried at least 3 different ways). if you can do it, you can probably get a decent quality one-way video stream with as low as 30kbps
