Plugin codecs question
by JF NP 08 Jul '09

08 Jul '09

Hi all: I'm trying to migrate an small test project that used OpenH323/PWLIB to H323Plus/PTLib. In that project, I've the following lines of code: H323Capability *h263Cap = new H323_RFC2190_H263Capability(0, 2, 0, 0, 0, videoMaxbandwidth*1024/100/*, FALSE, FALSE, FALSE, FALSE, TRUE, 0, 0, 0, 0, 0, 0, 0, TRUE*/); h263Cap->SetCapabilityDirection(H323Capability::e_ReceiveAndTransmit); SetCapability(0, P_MAX_INDEX, h263Cap); I've seen that the class H323_RFC2190_H263Capability does not exists anymore. My question is: what is the new mechanism to specify a max bandwidth for the H.263 capability, in order to be used in codec negotiation? Also, I 've code that looks like this: unsigned int maxBitRate = (((H323_RFC2190_H263Capability*)capability)->GetMaxBitRate()*100)/1024; in the Transmit() method of the H323SenderChannel derived class. Is there any way of getting the negotiated MaxBitRate for the H263 codec? Thank you in advance,

Video codecs are now plugins. You must compile the H.261 plugin and place the DLL’s in your application directory. Here is something you should know MyPhone will not compile with the lasted H323plus source code as I have not had time to upgrade the program. Some Video Camera will not work with the MyPhone2 0.4 because the DirectShow support in ptlib v1.12 does not work. H.264 is not supported. H.263 requires you compile the plugin and put the FFMPEG dll in app directory Basically it is currently broken, if you want to use MyPhone for the basis of a commercial product then you will need to do a lot of work to get it to compile with the latest h323plus version and currently I do not have the time to volunteer to do the job . Sending repeated emails to any address you can find is NOT going to get the support you require. Please refer all questions to the mailing list or otherwise your emails will be ignored.

Re: [h323plus] OpenMCU shutting down unexpectedly
by Michael Miller 08 Jun '09

Here's what I get when I use the debug version of OpenMCU located in : h323plus_src/applications/openmcu/obj_linux_x86_d You can see that I was able to connect a client and then the second client crashed OpenMCU. The first unit was a polycom vsx-8000 the second was a polycom vs-4000.

I would enable core dumps ("ulimit -c unlimited") and then execute the debug version of openmcu right out of the compile directory (./obj_linux_x86_64_d/openmcu ...."). When you then crash openmcu, you can start gdb with "gdb ./obj_linux_x86_64_d/openmcu core" and execute a "bt" command to see where it crashed.

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. 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

H.239 function problem

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.

Hi All, I would like to know the difference between FACILITY and EMPTY message. While doing TUNNELING I am getting OLC body through EMPTY header(H225). Can I use FACILITY method instead of EMPTY. Thanks, Prashant "Save Tree Save Humanity"

Cannot set codec video mode
by Zack Tidwell 24 Apr '09

24 Apr '09

Hello, I have video call application using h323plus v 1.20.1 and PTLIB v 2.0.1. I am using the Vic H.261 codec V 1.20.0. I am trying to set the codec video mode to either AdaptivePacketDelay or DynamicVideoQuality in the OpenVideoChannel callback when isEncoding is true. However, after I set it, codec.GetVideoMode always returns 0. Furthermore, as far as I can tell, I am unable to set any other codec options, such as max bitrate, TxQualityLevel, or TargetFrameTimeMS. This is the same place I was calling SetVideoMode back when the application used OpenH323. Furthermore, it is the same place these functions are called in the myphone2 application. I have tried using the ffmpeg h.263 codec to the same effect. I have also tried using the latest version from CVS, which didn't help. Can someone give me a hint as to why this is not working? -Zack
