I am doing videoconferencing since the early 90s and i am researching =20= in the past years about large scalable secure video conferencing a lot. After i meet my main developer in 2008 we started to implement =20 "opencu" based on the old protocol papers i=B4ve found. At that time there was no efficent opensource codec and Qt wasnt =20 opensourced too, so we decided to use wxwidgets and xvid / portaudio =20 to implemented the basic features and made an proof of concept client. =20= (The server/refector isnt re_enineered yet, only java hack available ) He got a job offer to implement such a commercial system but he failed =20= after some attemts on latency and serverload. So after i' ve tested most of all available systems like paltalk, =20 ivisit, camfrog and jmeeting, webmeeting and so on , i figured all =20 solutions whitch were mostly implemented in the 90s worked more or less worse =20 and had latency about 4 seconds and were not opensource at all. So I decided to re_implement our social -zero-conferencing idea with =20= VP8 whitch was aquired from google in 2010 and got "opensourced" and seems highly efficent for the video part and WAB bonjour a =20 zeroconfiguration service discovery framework developed by dr.steward chesire from apple. After i see the issues my developer had, this "unbufferbloat project" =20= came to my attention because latency and buffering seems to be the =20 main issue in realtime communication plattforms. I am looking forward to see how this problems would be solved. regards Marc On Aug 25, 2011, at 4:18 AM, Dave Taht wrote: > oops, the thing I was hoping for more eyeballs on was: > > http://www.bufferbloat.net/issues/249 > > in addition to 243. > > --=20 > Dave T=E4ht > SKYPE: davetaht > US Tel: 1-239-829-5608 > http://the-edge.blogspot.com > -- Les enfants teribbles - research / deployment Marc Manthey- Vogelsangerstrasse 97 50823 K=F6ln - Germany skype: MarcManthey Tel.:0049-221-29891489 Mobil:0049-1577-3329231 site: http://let.de project : http://opencu.org twitter: http://twitter.com/macbroadcast/ Opinions expressed may not even be mine by the time you read them, and =20= certainly don't reflect those of any other entity (legal or otherwise).
