H323plus v 1.22 and ptlib 2.6.5
by Sebastian Peschko 13 Nov '09

13 Nov '09

I wonder if someone can help out here. I am having trouble with Asterisk Crashes caused by libpt and openh323 where I am using Asterisk 1.6.2rc5 and h323plus v1.19.0Beta7 and ptlib v1.12.0. In this config when compiling the 2 packages and then doing a make in the asterisk H323 directory it automatically activates the chan_h323 in the Menuselect options of Asterisk and allows me to compile asterisk with h323plus support. The problem I am having is that I am registering with a Nortel H323 GateKeeper and when this looses the registry for some or other reason as a backup I send the calls using a Gateway directly to the Nortel PBX. With this configuration in v1.4.23 it was working perfecttly with openh323 v1.18.0 and pwlib v1.10.3. The problem came when because of issues with openmfcr2 I needed to upgrade to 1.6 for the embedded openr2 support. For this reason I am no trying to compile Asterisk 1.6.2.0rc5 with the latest h323plus v1.22.0 and ptlib 2.6.5. At the moment once these 2 packages are compiled it does not allow me to activate or select chan_h323 in the Asterisk "make menuselect". How can this be activated? I hope someone can help. Sebastian

Guys Just a quick note. http://www.packetizer.com/ipmc/h323/whatsnew_v7.html It has been nearly 3 years from my first submission to final approval on H.460.23/.24 but finally it's done. H.323 now has a standard complete NAT traversal solution. Simon

simph323 - could not open sound device

I am trying to get simph323 to work, but I having some trouble w/ the audio. Running h323plus-v1_21_0 with ptlib-2.4.5 on Linux.

Looking at ptlib/common/sound.cxx PSoundChannel it is baseChannel->PChannel::IsOpen() which returns FALSE For a quick test I changed the line to baseChannel->IsOpen() which makes it jump that hurdle and simph323 connects with the other h323 end and sound bits are exchanged. Here is the thing that puzzles me! I am using the same version of ptlib with opal (e.g. simpleopal) and don't see this problem. Code is build and run on the same machine. Any thoughts? mat

Opal H.264 plugin with OpenMCU and H323plus
by Prasad 06 Nov '09

06 Nov '09

Hi, I have taken latest code for ptlib, h323plus, avplugins from h323plus and H.264 plugin from opal. I manged to have video call on OpenMCU with H263. I found it has dependency on specific version of libavcoded, 0.4.7. For H264 I compiled the code and put the .so in $PWLIBPLUGINDIR, also I put libx264 in $LD_LIBRARY_PATH. But somehow H.264 codec is not getting loaded. The libraries are getting linked on start of openmcu but I cant see capabilities being added in OpenMCU traces. Is there any specific version of libx264 needed? I tried with version 78 and 67. Also, H264 requires avcoded too. Is this needed to be built with option --enable-libx264 ? -- Prasad

Openmcu execution issues

Hi, I've compiled openmcu with all the dependencies. When I execute openmcu -xc, I get the following error on termimal 2009/11/03 20:50:10.777 HTTP Service:b7c00a78 Error HTTPS Accept failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate 2009/11/03 20:50:10.790 HTTP Service:b7c00a78 Error HTTP server creation/open failed. and I am unable to access https://127.0.0.1/1421 with following error on browser. An error occurred during a connection to 127.0.0.1:1421. You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information: Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number. (Error code: sec_error_reused_issuer_and_serial) Previously I also got some error related to server.pem. I tried to delete the certificates of openmcu from browser properties but that also didn't work. I also tried to enable and disable SSL 3.0 and TSL 1.0 but that also didnt work.

H.263 and H.264 at OpenMCU. Removing capability. Why?
by HUB Netsky 03 Nov '09

03 Nov '09

Hi, all. I'm trying to set up an MCU server on SLES11 x64 with latest patches. I've grabbed the latest snapshots of ptlib and opal libraries (from http://opalvoip.svn.sourceforge.net) and latest h323plus and OpenMCU (from http://h323plus.cvs.sourceforge.net) After successful compilation with debug flags and a slight modification of Makefiles to repair "make install", I'a able to launch openmcu. But it gives messages like these in the startup log: ============ quote of openmcu startup ============= 2009/11/03 15:00:37.682 OpenMCU Debug2 H323 Found capability: H.261-QCIF{sw} <25> 2009/11/03 15:00:37.683 OpenMCU Debug2 H323 Removing capability: H.261-QCIF{sw} <25> 2009/11/03 15:00:37.684 OpenMCU Debug2 H323 Found capability: H.261{sw} <26> 2009/11/03 15:00:37.684 OpenMCU Debug2 H323 Removing capability: H.261{sw} <26> 2009/11/03 15:00:37.685 OpenMCU Debug2 H323 Found capability: H.263{sw} <27> 2009/11/03 15:00:37.686 OpenMCU Debug2 H323 Removing capability: H.263{sw} <27> 2009/11/03 15:00:37.687 OpenMCU Debug2 H323 Found capability: MPEG4{sw} <28> 2009/11/03 15:00:37.688 OpenMCU Debug2 H323 Removing capability: MPEG4{sw} <28> ============ end of quote of openmcu startup ============= And when the final codec list is printed, it looks like this: ============ quote of openmcu startup ============= 1: H.261-CIF{sw} <24> 2: ============ end of quote of openmcu startup ============= And like the last message shows, OpenMCU doesn't use h263 and MPEG-4 codecs, only H.261 Codecs for H.264 are compiled too and placed just near the other (h261,h263) codecs, but aren't even being noticed by openmcu. I've tried both with h323plus/plugins and opal/plugins by creating symlinks to their ".so" files in "/usr/local/lib/ptlib" directory. The same result, though many audio codecs from opal are being successfully loaded. The questions are: 1. Why openmcu removes capabilities that were successfuly found? 2. Why openmcu doesn't load plugins in the plugin dir? Thanks for any response. Tell me, if any additional info is required. -- HUB

Porting Project for Visual Studio 10 Beta
by Marcos Fábio Jardini 28 Oct '09

28 Oct '09

Hello people Call me crazy but since I'm testing new Visual Studio 10, the awesome C++0x lambda functions, rvalue reference and Parallel Pattern Library, I take the opportunity to see how PTLib and H323plus solutions compile on VS10. The nice news is now Microsoft will separate the compilation from IDE, now solutions/projects are more self-contained for use with MSBuild system (wich comes with Windows SDK), the 1st modification is to use the install-path env-var in the project file itself, like the *NIX flavors of H323plus, ie, the old "Tools->Oprtions->Projects and Solutions-> VC++ Directories" are now in "Project->Properties". Resuming, there is no more needed to hardcode H323Plus and PTLib paths on IDE, paths are now Project properties :) The 'configure' files updated to WindowsSDK v7.0A. Because VS path changing from beta 1 to beta 2 I'll wait until RC or RTM to write back the correct 'configure' file. The basic ptlib compiles fine. ----- Jogue RPG, alimente o lado criativo!
