opal and h323plus library
by andrew wang 06 Jun '09

06 Jun '09

hello everybody, I want to know the difference between opal and h323plus in client side. The two libs are all based on ptlib, and I think the two libs have the same function---h323 stack. I have made one window application which is above opal library. And I want to use h323plus lib, and don't change the application interface. Is there any difference between the application interfaces of opal and h323plus. Thanks. The question is very urgent to me. I'll appreciate your answers. And Please give me some valuable advice. Thanks. Best regards andrew

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

OpenMCU shutting down unexpectedly
by Michael Miller 02 Jun '09

02 Jun '09

Hello, I have OpenMCU compiled/installed from the latest cvs. When I get a third client connected, OpenMCU shuts down unexpectedly. It appears to get a shutdown signal from somewhere. I have attached an strace. Let me know if more info is needed. Also, in pursuing more info about this, I tried compiling OpenMCU with the debug option and got: ]# make debug make DEBUG=1 default_target make[1]: Entering directory `/root/openmcu-v2_2_4-src/applications/openmcu' g++ -I/root/pwlib/include -DPTRACING=1 -D_REENTRANT -I/usr/kerberos/include -fno-exceptions -Wall -g3 -ggdb -O0 -D_DEBUG -DPTRACING -I/root/h323plus/include -felide-constructors -Wreorder -c main.cxx -o obj_linux_x86_d/main.o g++ -I/root/pwlib/include -DPTRACING=1 -D_REENTRANT -I/usr/kerberos/include -fno-exceptions -Wall -g3 -ggdb -O0 -D_DEBUG -DPTRACING -I/root/h323plus/include -felide-constructors -Wreorder -c video.cxx -o obj_linux_x86_d/video.o video.cxx: In member function ‘PBoolean MCUSimpleVideoMixer::ReadSrcFrame(VideoFrameStoreList&, void*, int, int, PINDEX&)’: video.cxx:953: warning: comparison between signed and unsigned integer expressions video.cxx:953: warning: comparison between signed and unsigned integer expressions g++ -I/root/pwlib/include -DPTRACING=1 -D_REENTRANT -I/usr/kerberos/include -fno-exceptions -Wall -g3 -ggdb -O0 -D_DEBUG -DPTRACING -I/root/h323plus/include -felide-constructors -Wreorder -c conference.cxx -o obj_linux_x86_d/conference.o g++ -I/root/pwlib/include -DPTRACING=1 -D_REENTRANT -I/usr/kerberos/include -fno-exceptions -Wall -g3 -ggdb -O0 -D_DEBUG -DPTRACING -I/root/h323plus/include -felide-constructors -Wreorder -c filemembers.cxx -o obj_linux_x86_d/filemembers.o g++ -I/root/pwlib/include -DPTRACING=1 -D_REENTRANT -I/usr/kerberos/include -fno-exceptions -Wall -g3 -ggdb -O0 -D_DEBUG -DPTRACING -I/root/h323plus/include -felide-constructors -Wreorder -c custom.cxx -o obj_linux_x86_d/custom.o g++ -I/root/pwlib/include -DPTRACING=1 -D_REENTRANT -I/usr/kerberos/include -fno-exceptions -Wall -g3 -ggdb -O0 -D_DEBUG -DPTRACING -I/root/h323plus/include -felide-constructors -Wreorder -c h323.cxx -o obj_linux_x86_d/h323.o h323.cxx: In member function ‘virtual PBoolean OpenMCUH323Connection::OnIncomingAudio(const void*, PINDEX)’: h323.cxx:926: warning: comparison is always false due to limited range of data type g++ -I/root/pwlib/include -DPTRACING=1 -D_REENTRANT -I/usr/kerberos/include -fno-exceptions -Wall -g3 -ggdb -O0 -D_DEBUG -DPTRACING -I/root/h323plus/include -felide-constructors -Wreorder -c mcu.cxx -o obj_linux_x86_d/mcu.o make -C /root/pwlib/src/ptlib/unix debug make[2]: Entering directory `/root/ptlib-2.6.2/src/ptlib/unix' make[2]: *** No rule to make target `debug'.

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.

FYI From: h323implementers-bounces(a)lists.packetizer.com [mailto:h323implementers-bounces@lists.packetizer.com] On Behalf Of leandro.alvares(a)caixa.gov.br Sent: Friday, May 22, 2009 5:58 PM To: h323implementers(a)lists.packetizer.com Cc: h323plus-join(a)lists.packetizer.com Subject: [h323implementers] bug: openMCU-v2.2.4 4CIF resolution Hello everyone, I'm using ffmpeg-0.5, opal-3.6.2, h323plus_1.20.5, openmcu-v2_2_4-src and ptlib-2.6.2. 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

I'm using h323plus 1.20.5, ptlib 2.6, ffmpeg 0.5 and openMCU 2.2.3. I've compiled Opal to generate plugins like H.263, H.264, G.722, etc... but when I run OpenMCU, it don't use H.264 codec, it find H.261, H.263 and MPEG4, bu it don't use H.264.... I read that H.264 is aplicated by H.245... I read too tha have a lot persons who added H.264 support in their openMCU, but they don't talk who did that. How can I do that? I really need to know that

Greg, I've copied the H323 Plus mailing list. I suspect somebody on there, either the H323 Plus or Opal team members, will be able to address your question.
