OpenMCU - H263 and Connection Problems.
by Daniel Rammelt 02 Jun '09

02 Jun '09

Hi all, I am currently trying to get OpenMCU up and running on Debian 5 but am encountering some issues. Firstly, None of the clients I have tried (Mirial, Evo, Ekiga, Lifesize HD unit, etc) will connect at anything other than H261. I have OPENH323DIR=/usr/local/lib/openh323/ PTLIBPLUGINDIR=/usr/local/lib/opal-3.6.1/ Is there someway to see why the H263 codec is not loading? I have build it in Opal. Do I need to specify it somewhere? Second problem is that, when more than 2 clients join the conference everyone but the last person to join is disconnected from the conference. All clients are on the same network with no firewalls etc. I have tried looking into the trace.txt but I do not really know what to look for and there is alot of stuff in it. -- =========================================== Daniel Rammelt Advanced Video Collaboration Centre (AVCC) http://avcc.karen.net.nz

Leandro, Thanks! that resolved the problem with the certificate. And setting the PTLIBPLUGINDIR solved the video problem! I'm so close! But now it's not registering with GNU Gatekeeper. I think it's a password problem. I can see how to 'add' a password with addpasswd but addpasswd is giving me a floating point error. I'm compiling gnugk 2.2.8 now. And I'll let you know what happens. Thanks much for your help.

I have already used PVX 8 and some videconference endpoints from different brands/types. I've seen that it is possible to force openMCU to use 4CIF resolution by modifying the framesize parameter in mcu.cxx. So, I forced the value to 4cifMPI. However, when I start the connection, it shows me a "green - all messed up image" and when I try to connect two clients to the same MCU room the process exits display this error message: "Segmentation fault" When I change this setting to use cifMPI resolution only, it runs fine. Is there a patch to solve this problem? Can someone help me? Thanks in advance. Best regards, Leandro
