<DIV></DIV>By the way, I wonder now!<BR>If people are videoconferancing, is it

everybody see the one that talks. So if you want people to see you, you

provided everyone use the same codec, there is another solution which<BR>>
only shows the talker's incoming video stream, i.e. do not mix video,<BR>>
only audio. There has to be some delay though, so the videostream<BR>>
does not jump around all the time as someone coughs...<BR>>
<BR>>
Some people on this mailing list are working on it and we're discussing<BR>>
how to make it into a contribution for Asterisk 1.6.<BR>>
