Openmcu execution issues
by Sohil Shah 03 Nov '09

03 Nov '09

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. I understand that this is some certification related issue but I'm not able to solve it. My openmcu version is 2.2.1, Test machine Fedora 11 and Firefox web browser version 3.5.3. I hope openmcu issues are addressed on this mailing list. Let me know if you need more details. -- Thanks& Regards, Sohil Shah -- _____________________________________________________________________ Disclaimer: This e-mail message and all attachments transmitted with it are intended solely for the use of the addressee and may contain legally privileged and confidential information.

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!

In order to take more control over the uptime of the STUN servers, can we just place a number of public STUN servers in the variable: H46023STUN=stun.site1.net,stun.site2.net,stun.site3.net,stun.site4.net,stun… I assume that h323plus based endpoint, like the simpleh323 one, will receive the full list and will try another STUN server if previous one fails to connect. BTW: Just a thought that it would be great if GnuGK integrates STUN server in itself, using the open source STUN server code. Marcus

Yuriy Are you using H.460.18/.19 on the gatekeeper? Is that where you think the leak might be? Or it's a general leak in GnuGk?

Direct Media (H.460.18/.19/.23/.24) Testing
by Simon Horne 21 Oct '09

21 Oct '09

Guys Over the last few weeks Jan and I have been hard at it testing the Direct Media (no proxy NAT traversal) support in GnuGk and H323plus. We are now relatively confident we have direct media working under most conditions. If you are interested in testing then Gatekeeper then download the latest GnuGk CVS and compile. You can also use the latest H323plus CVS if you want to build a simple endpoint. If you want a quick test under windows. The PacPhone website has the (latest compiled) pacphone client and a windows installer for GnuGK. Remember you may need a STUN server for H.460.23/.24 support. If you have Tandberg or other equipment that supports H.460.18/.19 you may want to try and test also. It would be good if as many people as possible would test the code before the GnuGk 2.3.1 release. Simon

How to add for H323EndPoint capability for codec G.729 into h323plus library?
by Marek Wlizło 11 Oct '09

11 Oct '09

Hello! On the last Friday I decided to upgrade my project’s libraries: pwlib 1.10.0 -> 1.12.0 and openh323 1.18.0 -> h323plus 1.19.7. The project's application is a media-signaling gateway from DSS1 to H.323 protocol using my hardware with DSP for media converting. With previous openh323 library I don’t have any problems with adding codecs supported by my DSP to capabilities table – I just simply create object ‘mydevice’ of class MyOpalDevice : public OpalLineInterfaceDevice and inside of it just add table ‘CodecInfo’: -static struct { const char * mediaFormat; } CodecInfo[] = -{ - { OPAL_G729A }, - { OPAL_G711_ALAW_64K }, - { OPAL_G711_ULAW_64K }, - { OPAL_G729 } -}; - -//------------------------------------------------------------------------------------------------- - -static PINDEX FindCodec(const OpalMediaFormat & mediaFormat) -{ - LOGDBG(_("%s"), __PRETTY_FUNCTION__); - - for (PINDEX i = 0; i < PARRAYSIZE(CodecInfo); i++) - { - if (mediaFormat == CodecInfo[i].mediaFormat) - return i; - } - return P_MAX_INDEX; -} - -//------------------------------------------------------------------------------------------------- - -OpalMediaFormat::List MyOpalDevice::GetMediaFormats() const -{ - LOGDBG(_("%s"), __PRETTY_FUNCTION__); - - OpalMediaFormat::List formats; - - for (PINDEX i = 0; i < PARRAYSIZE(CodecInfo); i++) - { - formats.Append(new OpalMediaFormat(CodecInfo[i].mediaFormat)); - } - return formats; -} After this it was enough to use static method: H323_LIDCapability::AddAllCapabilities(&mydevice, capabilities, 0, 0); during initialization of my endpoint in method: GatewayEndpoint::Init(bool initial) (where class GatewayEndpoint : public H323EndPoint). In h323plus there is not defined class OpalLineInterfaceDevice and for two days I can’t find the way how to use codec’s capabilities different than G.711-ALaw-64k{sw} or G.711-uLaw-64k{sw}. I need to add G.729 and G.729A. I must mention that I have read documentation from http://www.voxgratia.org/docs/faq.html#5_1 and there is explained how to use external plugins with software codecs. In my case I need to put into my GatewayEndpoint capabilities table information that my DSP just supports (G.729 and some others). Please help.

Help with OpenMCU
by Mike R. 09 Oct '09

09 Oct '09

Hey, I've been trying to get OpenMCU working, but I've run into some problems. I'm using a trunk build of h323plus, ptlib, and openmcu (though I have tried several versions), on Ubuntu Linux (9.04). I am able to get voice working, but I cannot get video working. I compiled h323plus with all possible video codecs. When I place calls, on the status page, for video it reports a framerate of 0, and codec none/none By using a simple printf, I determined that the function OpenMCUH323Connection::OpenVideoChannel was never called. I made sure the "Enable Video" option was checked on the Parameters page. I have tried calling with a D-Line DVC-2000 i2eye, and a Polycom HDX 8000. Any help would be greatly appreciated. Thanks, -- --Mike

Thank you for clarification. I thought downloading a dll from *somewhere* might be a security risk. Furthermore, there was a security update from Microsoft which updates mfc71.dll, and the mfc71.dll downloadable from the internet has a version number before this security update. I'll keep looking for a more up-to-date version of the dll. Wilfried
