  • Debug a video conferencing application (How?)

    Hi,
    I am developing a video conferencing application and would like to know your opinions on efficiently debugging such application if I am alone.
    Thank you

    Well, if you are alone you can still have two computers and have a conference with yourself.
    You will need a group of volunteers to help you test it in any depth.

  • Creating video conferencing application?.

    hello, im a newbie in JMF. How should i design a video conferencing application that uses less ports for transmitting audio and video streams? since i have read in the API that there is a separate port to be used for audio and video. and what comes into my mind. the use of ports may increase since more users can come in and join the conference, and also interact with the conferencing. Thanks. I would like to hear a lot of response from people who have already created such application.

    Hi,
    Already set audioReliable & videoReliable false on publisher & player nestream.
    Still the lag is there. Is there any latency buffer settings anywhere ( on server which each peer copies?)

  • Video Conferencing in Air 3 for Android/IOS

    Hi,
    We are in the process of creating a Video Conferencing application for Android and IOS devices, the app would be published on Android and IOS market.  I have some quires related to using Air 3.0 for the development:
    For Android devices Front facing camera is supported only in Air 3.0, but can we assume Air 3.0 would be officially available by end of this year?
    Would this feature available for all Android 2.2 and above devices?
    Can we use Flash Media Server/any other streaming server for video conferencing?
    I have read in some of the post that Apple store do not allow video streaming with RTMP, is this true? Is there any work-around to use streaming video from within Air app for IOS?
    Thanks in advance!

    I used milkmangames ANE. (50$), because i didnt want to fork the code for each os.
    http://www.milkmangames.com/blog/tools/
    It was "easy" to set up (quotes: as easy as something complicate can be).
    Consumables, or One-time-purchases worked out of the box, but restore, subscriptions and auto subscriptions (like newspapers) had bugs like hell and were unusable.
    Also check out here for some free stuff (wich propably works as well as the comercial, "supported" stuff, stupid-me)...

  • Need help with an Apple Video Conferencing webcam

    I am having a fit trying to get my Performa (6500/225) to work with the hardware I have. Previously I had a Performa 6400/180. I have an Apple Video Conferencing webcam that I was able to make work with OS 9.1. It worked with the original software that came with it and it worked with the software for the Logitech Quickcam (QuickPict setting) I was even able to use it with Ivisit (webcam program). Now that I've had to change the harddrive and reinstall everything, it doesn't work with anything but the original software.
    Can anyone tell me what extensions I might need or how to configure it so it will work with what I already have?
    Performa 6500/225   Mac OS 9.1.x  

    Thanks to all who tried to help. As it turned out it was not a problem with the cam. It took some time and some tweaking but I did get it to work. I had a problem with the webchat program iVisit and I was able to get that solved thru their tech support forum.
    This Apple Video Conference camera was a great find. I recommend it to anyone who still uses a vintage mac like mine. What a shame it was discontinued.

  • Video conferencing help

    Hi Guys,
    Im extremely new to java, im trying to find out how to go about setting up a peer to peer video conferencing on my website. So that users that are logged into my site
    can chat to each other. Does anyone know of any tutorials around that can help me?
    thanks.

  • Video conferencing through Flex2

    Hi,
    I am a newbie to Flex and wanted to know whether applications
    like video conferencing, audio conferencing or chat are possible to
    be developed in flex. If yes how could it be developed. Kindly
    suggest me some tutorials or sites from which i could get the
    required help.
    Thanks and Regards

    I'm a newbie too and found this site...
    http://mx.sys-con.com/read/223822.htm
    It covers how to set up an application where you can see
    yaself in the web cam and I think also stream the cam image through
    a flash media server...although not sure.
    Managed to get my cam image working fairly easily and
    embedded in the application window which is the main thing though.
    Not totally sure how you would go about getting the other person's
    camera to appear on the same screen though...if you find out I
    would love to know.
    Good luck!

  • Video Conferencing Systems vs Basic IP Cameras

    Hello all,
    I am new to video over IP technologies.
    We need a system where 2 or 3 people can basically talk to each other (Audio/Video).
    A vendor is trying to steer us into purchasing a high priced video conferencing system, although I do not see the difference between a video conferencing "system" and some IP Cameras. As long as the people can see each other (through a web browser, or other method) and the cameras are of high quality, what's the difference between a IP Camera "system" and a Video Conferencing "system"?
    Thanks

    Well the question is how are you going to do conferencing with "just some IP cameras"? In its simplest form you need some type of application to do video conferencing. Smmething like Yahoo IM, AOL IM, Windows Messenger, NetMeeting, etc. These applictions tend to allow one-on one video conferncing but some are getting better. Even with apps as old as Netmeeting you could have more than 2 people on a call but you could only ever see 2 people at once at the most. Not sure about some of the new versions of IM clients though.
    In general you need an MCU (Multi-point Conference Unit) in order to have true multi-party conferencing.
    These units will allow everyone to see everyone else at the same time (within space constraints offered by the size of the monitor).
    There are plenty of (relatively) inexpensive MCUs out there and a vast array of features. I don't think the vendor is steering you in the wrong direction. The only problem is determining if an MCU is overkill or not. Perhaps using an IM client app might be enough for your needs.
    Hope this helps.

  • HT4534 Mac Mini HD Video Conferencing

    I am considering purchase of a mac-mini for video conferencing.  This article (http://support.apple.com/kb/HT4534?viewlocale=en_US) refers to "built in camera".  Of course, the mac-mini has no built in camera.  I would be using my HDTV for a monitor.  Can I use the Logitech c910 & the mini for HD Facetime?

    I also have a mac mini and am using the Logitech C920.  At the beggining, I had issues with its built in mics not working with FaceTime, but I found a solution for the problem and now all the programs that interface with the camera work great (FT, Skype, iMovie, etc).  If you do buy the C920 run into the same issue that I had with the mic not working, here is the quick solution for the problem:
    Cause of Problem:  The Logitech C920 camera/mic operates on a 2ch-16bit integer.  You can verify this by opening "finder + Utilities + Audio MIDI Setup" and then select the HD Pro Webcam C920 and look at the "Input" Default values.
    The Mac Mini's "Built-In Output" and "Buiilt-In Input" formats were set for 2ch-24 bit integer.  Therefore, the default input and output were out of sync with the C920 default format.
    Solution:  Change the Mac Mini's default Output to "2ch-16 bit integer".  You don't need to change the default Input but it doesn't hurt to do so.  Once you do this, the camera and it's built in mics work on facetime and all other video chat applications.

  • Pc-to-pc audio/video conferencing

    I've been looking into the ability of a direct (secure) connection from one Linux machine to another for the purposes of audio/video conferencing.  I know there's stull like ekiga but that requires an account and a third party server.  I'm looking for a solution that would be completely maintained between the two or three linux machines directly (webcam/mic).  What's out there that I'm not seeing in google?

    Also interested, been meaning to move away from Skype for a time now. I've looked/asked around and found opensips. You'll still need a client to manage calls though, I'll probably try out Twinkle. I'm going to spend some time trying to set it up myself. Hope it helps.
    Edit Note: I quickly moved from twinkle to linphone.
