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

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

NAT Traversal document
by Simon Horne 26 Sep '09

26 Sep '09

Guys Both GnuGk and H323plus CVS now support Direct Media or H.460.18/.19/.23/.24 in both slow and fast connect. These 4 standards work together to allow media to traverse NAT without requiring the media to be proxied. This greatly increases the scalability of video conferencing systems within NAT environments with only a small proportion of media needing to be proxied. I have prepared a not-so technical document which explains Direct Media and how the 4 standards interwork. http://www.h323forum.org/specifications/ I have also released a new version of PacPhone v2,2 (H323plus v1.22 CVS) and a windows installer for GnuGk v2.3.1 (current CVS) and both are available from the PacPhone website (www.pacphone.com <http://www.pacphone.com/> ).

I installed the plugins correctly and openmcu runs fine. However when using two polycom pvx clients to connect to openmcu using H.263 at 4CIF for both transmitting and receiving, the video is blocky and very distorted. There is no packet loss, the bitrate is set to 1920 kbps and the frame rate is a constant 30 fps for both transmitting and receiving. I was wondering if the problem is with openmcu or the pvx clients. Has anyone successfully used 4CIF resolution to be clear and smooth? Also, I had to massage the h.263 plugin code to get 4CIF to work with openmcu. Any help would greatly be appreciated. Adrien Rudulier Did you solve your problem? I'm having the same problem and I diddn't get some post to help me. I'm using the same softwares version than you. What did you do to enable 4CIF resolution? Thanks.

SVN PTLib 2.7beta1 Compilation
by Marcos Fábio Jardini 22 Sep '09

22 Sep '09

Hello I make a fresh new download from SVN PTLib trunk (2.7beta1) and CVS SimplePlus. The two compiles fine. I only have one question: is P_DIRECTSHOW2 really being compiled? Because there is no vidinput_directx2[.h/.cxx] in VS2008 project/solution (the 2 existis in source and header folders). Even ptbuildops.h.in, when transformed, do not include P_DIRECTSHOW2 definition (greyed by an #IF 0). Can I force P_DIRECTSHOW2 and the two headers in project/solution, or is needed something more to do? Regards, Eng. Marcos F. Jardini ___________________ [[ 0--,, ]]

Hello people Reporting back: * PTLib 2.6 (SVN Trunk): All compile fine and now DirectShow and Application properly works on projects outside PTLib_samples_2008.sln * H323Plus 1.22 (CVS Trunk): H46018_h225.h Error "H46019UDPSocket::GetLocalAddress" makes access to members "m_locAddr" and "m_locPort" but the two members are guarded by macro H323_H46024A and the method not.

Packetizer Forums Site Launched
by Paul E. Jones 25 Aug '09

25 Aug '09

Folks, Last week, I sent an email to a fairly large number of people wherein I raised an issue: there seems to be a need for a place to go for people to ask questions about signaling protocols, implementation, deployment, and various issues related thereto in the area of videoconferencing. There are various mailing lists and such, but people are scattered all over with no "right place" to go to ask questions. I get a lot of questions directed my way, simply because people do not know where else to ask. We are hosting a number of public mailing lists on Packetizer, some lists are hosted by the IMTC, others at Columbia and Ohio State, etc. Perhaps some of those lists are perfect for engineers or those working on standards, but I've noted that end users, especially, have no place to ask questions. Also, there are lots of questions related to open source projects that get posted to various lists, only because those products happen to use a particular protocol, etc. So, I took a poll asking whether folks would prefer a web-based discussion forum, email list(s), or a "nothing else is needed". Over 50% of those who responded to the poll indicated that they would like to see a discussion forum for VoIP, videoconferencing, and data conferencing discussions. So in response, I set up this site: http://forums.packetizer.com. The structure might not be perfect and since I had to write the ATOM/RSS code myself over the weekend, I will not declare it to be bug free just yet. Nonetheless, the board is running a stable release of phpBB3 and ought to work well. I certainly welcome any comments you have and will try to improve the structure and operation as issues are raised. I do hope you find this useful and I would encourage people with expertise in a particular area to join. I will personally be answering questions, as I have for years, but there are certainly others with better qualifications to answer questions in some areas than me. If anyone is interested in a moderator role on the site, let me know. If you have any questions at all, please don't hesitate to ask me. Paul

I thought that path file dlls in Tools->Option add,but again Video not shown. question : 1) How should DLL have to Project MyPhone add? 2) Whether I was in error?namely error in program Plugins or in h323plus? static void StartFastStartChannel(H323LogicalChannelList & fastStartChannels, unsigned sessionID, H323Channel::Directions direction) { for (PINDEX i = 0; i < fastStartChannels.GetSize(); i++) { H323Channel & channel = fastStartChannels[i]; if (channel.GetSessionID() == sessionID && channel.GetDirection() == direction) { fastStartChannels[i].Start(); break; } } } The Error is : Unhandled exception at 0x7c90e4ff in MyPhone.exe: 0xC0000008: An invalid HANDLE was specified. please you guide me.i have a lot of time that i try to solve this problem.

Behavior on VideoInputDevice
by Marcos Fábio Jardini 21 Aug '09

21 Aug '09

Hello everybody I just managed get some time to back to H323Plus code. Successfully compiled PTLib, H323Plus, Plugins, OpenMCU and SimplePlus near without modification, only one of plugins come with a PBollean type not found but easy fixed, I'll do the compilation again to confirm wich archive is and report back soon. I'm using a full instalation of Visual Studio 2008 Pro SP1 (embeded Windows SDK 6.0A instaled) For who having problems, put in the enviroment: PWLIB_CONFIGURE_EXCLUDE_DIRS, with the paths: * C:\Program Files\Microsoft SDKs\Windows\v5.0 * C:\Program Files\Microsoft Visual Studio 9.0\smartdevices\sdk * C:\Program Files\Windows mobile 5.0 SDK r2 This prevents pre-compilation step, Configure.exe, to search for extensions on wrong paths (Atention! if you are compiling for Windows Mobile remember to remove "C:\Program Files\Windows mobile 5.0 SDK r2" from exclusion search path) But I figured a behaviour: VideoTest from PTLib can find and use the WebCam with the "DirectShow" and "*" key search string in getDriversDevices. But SimplePlus not. If you start a new Solution to mimic VideoTest you will get the same bahaviour. Because VideoTest is marked dependency on PTLib on the build tree something getting wrong on projects outside PTLib Solution. I'll investigate, and try search for more clues. Just reporting to see if others having the same issue. Regards. Eng. Marcos F. Jardini -- ----- Jogue RPG, alimente o lado criativo!

Discussion Forum or Mailing List for Videoconferencing
by Paul E. Jones 19 Aug '09

19 Aug '09

<http://www.packetizer.com/> http://www.h323.net/images/shared/pktzr_ur_logo.png Folks, First let me apologize for this very unusual message, but I would really very much appreciate your feedback and suggestions on this topic. Over the past year, I have seen an increase in the number of videoconferencing-related questions. Sometimes these questions are development-related (for which there are appropriate mailing lists), but more often lately I am getting a lot of end-user questions. I get questions like "how do I configure product X to talk to product Y" or "how can I get video working with product X" or "what is the best video camera for use with my software videophone?" I'm also now getting questions about using XMPP for audio and video communication, which is a fairly natural extension of the IM/presence standard. (In case you were not aware, Google Talk is using XMPP and Google worked to define the Jingle extensions that make this possible.) Unfortunately, I am unable to provide good answer to some of these questions, but I know others on these lists are. Collectively, I think we could answer any question sent our direction. And, keeping with the spirit of why Packetizer was created in the first place, I would really like to offer a place for people to go to get the needed answers to their problems. Even you might have some questions and would like to have a place to go ask. That said, you might feel differently. So, before I create an on-line discussion forum or create a mailing list, I would like to get your input. Should I create a discussion forum, mailing list, or neither? Obviously, if I create it, I would want people to register / sign-up to participate, else it would be pointless. If you feel like you would likely never bother with visiting this web site or subscribing to a mailing list, then I'd like to know that: say "neither". Since there are over 1,000 people on these mailing lists (just considering those on Packetizer - likely more on the H.323 Forum list), I decided to create a poll for my benefit and the benefit of others who are interested in this topic. So, please go cast your vote: http://www.micropoll.com/akira/mpview/646129-195628 Please go take the poll, but do not do a "reply all" and send messages back to everybody. If you do want to talk to me about this, though, feel free to reply to me privately. Kindest Regards, Paul E. Jones Rapportuer, ITU-T Q2/16, Q12/16

BYO video conferencing
by Edward Harvey 11 Aug '09

11 Aug '09

I’m not sure this is the appropriate list – please feel free to send me somewhere else. I’m a decent and robust IT guy, but new to video conferencing. I’m looking for advice from folks who really know this stuff inside out (that’s you guys.) ;-) I would like to build a solution for the company, where our own private server acts as the relay/gatekeeper/stun/registrar (not sure which terms are technically right) so my Mac / Linux / Windows user clients can all communicate with each other via voice & video (and hopefully chat and file transfer too). From anywhere on the internet. I’m hopeful to have a company addressbook, so admins can add/remove users and users will automatically have that updated, and so on. Basically I want to build a low-cost enterprise video conferencing system. Commercial products are ok, provided they’re not crazy expensive (as some are). I am looking at products like Xmeeting, openMCU, gnugatekeeper, and so on … I must admit some confusion about which ingredients are required, and then, some more confusion about pro/cons of the different varieties of each ingredient. Any advice would be appreciated… Thank you…

H.460.18/.19/.23/.24/.24A support now in GnuGk / H323plus
by Simon Horne 09 Aug '09

09 Aug '09

Guys I would just like to let you know that GnuGk 2.3.1 (CVS) and H323plus 1.21 (CVS) now support the complete H.323 NAT Traversal solution. This a major step forward for both projects and H.323. I have built a sample windows installer for GnuGk and MyPhone (CVS version) for demonstration purposes. GnuGk Windows Installer (Win2000 or above) www.h323plus.org/standards/GnuGkSetup231.exe MyPhone Installer (XP or above) www.h323plus.org/standards/MyPhoneSetup121.exe Any queries then please address them to the appropriate mailing lists. Details for what the standards do: H.460.18 Mechanism to enable registration and call signalling traversal across a NAT/FW H.460.19 Mechanism to enable media traversal (proxying) across a NAT/FW H.460.23 (ITU approval in November) NAT detection and classification H.460.24 (ITU approval in November) Point to Point Media through NAT. Allows media to traverse NAT/FW without the need to proxy media (disable H.460.19). H.460.24 Annex A Same NAT RTCP probe. Extension of H.460.24 to allow endpoints behind the same NAT/FW to probe for direct connectivity. The standards documents are available from Packetizer. http://www.packetizer.com/ipmc/h323/standards.html http://www.packetizer.com/ipmc/h323/doc_status.html Simon
