F/OSS Multi-Point Video-Conferencing

DarkSarin writes "Given that solutions like iChat can seamlessly video-conference for multiple parties on the Mac, and that others are semi-commercial, like Oovoo (which recently left beta and is no longer free for more than 3-way calls), what do you recommend in terms of a F/OSS solution to a need for moderate-sized video-conferencing? Ideally, it would be something which does not use a web-page and does not require hours of configuration. iChat is insanely easy to use. Mebeam.com is also quite simple to operate, but requires so much screen real estate that it can't easily be used in conjunction with any other software. Referring to other documents while in the middle of the conference is nice, but it's important to have the reactions of the other participants — and not everyone has multiple monitors. I am aware of projects like vmukti and services like ustream.tv, but I am thinking more in terms of a stand-alone application that is F/OSS (Ekiga/GnomeMeeting comes to mind, but it does not do multi-point video chat unless one also has access to an H.323 gateway, which is apparently non-trivial to implement). With the prevalence of broadband connections, I am surprised that a solid effort is missing for making easy, painless multi-point video-conferencing for more than 3 or 4 connections (which seems to be the most that a lot of 'free' solutions offer, or even the low-cost ones). So, my question is two-fold: First, why isn't there a better effort at medium to large video-conferencing that pretty much anyone can set up? Second, do you know of any F/OSS applications which work well and support a minimum of 6 to 8 connected parties?"

  1. Skype? by Goeland86 · · Score: 4, Informative

    I know Skype isn't FOSS, but the latest Linux beta for skype does video chat with windows.
    I was pleasantly surprised when I tried it last week from my linux platform.
    It also does n-way calls. And runs on Linux, Windows and Mac. Something to follow up on?

      Skype can't do 3 way video conferencing, which is what the original poster was asking for. (I know, I've tried.)

  2. h323 by Lord+Byron+II · · Score: 4, Informative

    Any h323 client will do the job, like Ekiga (formerly GnomeMeeting). Also, for those in the science community, evo.caltech.edu is a nice Java-based collaboration tool.

  3. AccessGrid? VRVS? by Anonymous Coward · · Score: 3, Informative

    Accessgrid:

    Works fine, even supports multipoint *HD* video conferencing, open source though the "hours to set up" depends on your tech competence. It doesn't *need* working multicast, but works a lot better with it.

    Not really AG-specific: Also note that multipoint video conferencing requires either echo cancellation (and ALL software echo cancellation sucks, you need still need hardware DSP units even in 2008) or headsets for everyone - one bad node can ruin they meeting - if you think an echoey 2-way conversation is bad, you should experience a 15-way conference some time (though that might need academic/military bandwidth :-) )

    http://accessgrid.org/

    EVO? (Successor to VRVS).

    Kind of new, but descendant of VRVS. Kind of a cut-down accessgrid. Easy to use, though is web-page based.

    AFAIK, like VRVS, interoperates with AccessGrid, though participants in a conference tend to be "second class citizens".

    Given that the newest package listed on their site is from 2003, I might consider a different project. Gnomemeeting is one option, however I haven't found it to be that user friendly. You could use GTalk, assuming they all have Google accounts.

    http://www.mebeam.com/ has a plug-in for GTalk that allows for multi-way video conferencing.

  5. Re:software echo cancellation by btempleton · · Score: 3, Informative

    They do. The latest skype's echo cancellation is very good and done in software. They are also doing 640x480 at 24-30 fps, which is broadcast video quality, if you have the bandwidth and CPU for it. (about 800kbits up and a dual core.)
