[IMC-Video] video streaming discussion...

Tue Sep 26 08:42:39 PDT 2006

hi all!
one issue i noticed is that people sometimes has problems to watch DSS 
streaming when you are using nat, because DSS uses a udp way to transmit the 
data, usually the user has to activate RTP over TCP inside the player.
I tried DSS running in a Linux system, but i think dss is the same in maco$x 
and linux.

I'd like to see ogg/dirac foi icecast streaming!
to embbed ogg video, people use cortado, that is a java applet, that any 
browser w/ java can run.
http://www.flumotion.net/cortado/

one another good option for live video is use ekiga, that is a voip softphone, 
that, w/ an asterisk server well configured from indytel people 
( http://www.blagblagblag.org/BLASTERISK/ ), can broadcast video w/ very low 
latency and bitrate, and in both directions :-)

bye,
rafael diniz
