<div dir="ltr"><div><div><div><div><div><div>Hello guys, <br><br>I am trying to use
FreeSWITCH as a conference server for group calls. I'm using
mod_conference, and I know it works fine with multiple SIP clients (for
testing purposes I use Ekiga and Jitsi on both Windows and Linux). Audio
is mixed individually for each user, and video is switched based on the
active talker, and the same video is sent to all clients.<br><br></div><div>The
problem shows up when I join the group call using a Polycom hardware.
If I configure FreeSWITCH to support H.263 only, it works fine, my
Polycom can display the video sent by FreeSWITCH, including when the
active talker is itself. The other SIP clients work fine as well.<br><br></div><div>When
I configure FreeSWITCH to support H.264 only, the video switching only
works when Polycom is the active talker, otherwise all the users just
see the last video frame sent by Polycom. <br>If I do a peer-to-peer
call between the Polycom and a SIP client, both configured to use H.264,
everything works just fine, which points me that the problem could be
related to the transition between viewing a video stream with a given
resolution and viewing another video stream with a different resolution,
or something related to the non-continuity of video packets timestamp.<br></div></div><br></div><div>Is
there anybody out there that have experienced similar issues? Do you
guys have any suggestion or anything that could help me to make it work
properly?<br></div></div></div><br></div>Thanks in advance.<br clear="all"><br>-- <br><div class="gmail_signature"><div dir="ltr">Att. Mário Gasparoni.<div><a href="http://www.inf.ufrgs.br/~mcgjunior" target="_blank">www.inf.ufrgs.br/~mcgjunior</a></div></div></div>
