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.

4CIF support at OpenMCU
by leandro.alvares＠caixa.gov.br 22 Sep '09

22 Sep '09

Hi all, I finally did the modifications to enable the 4 CIF capability. In my trace, All entries has CIF4 = 2.. But the PVX client are not sending video, the OpenMCU doesn't receive video. I'm sending the modifications. Am I right? if not, What should I have to do? I'm still getting the PColCnv PColourConverter constructed: YUV420P 704x576 -> YUV420P 352x28 at trace.

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--,, ]]

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
