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

PTimedMutex::Wait patch
by Nir Soffer 17 Feb '09

17 Feb '09

In PTimedMutex::Wait(const PTimeInterval & waitTime), when pthread_mutex_timedlock is not available or broken (it is broken on our arm platform), the code always sleeps before checking the finish time, which is incorrect. For example, if you call Wait(0), and fail to acquire the lock, you will sleep for 10 milliseconds before you get back the retrun value. This is a bigger issue if you use H323EndPoint::FindConnectionWithLock: PWaitAndSignal mutex(connectionsMutex); H323Connection * connection; while ((connection = FindConnectionWithoutLocks(token)) != NULL) { // XXX this will block for 10 milliseconds if the lock can not be acquired! // TryLock calls Wait(0) which sleeps for 10ms on failure switch (connection->TryLock()) { case 0 : return NULL; case 1 : return connection; } // Could not get connection lock, unlock the endpoint lists so a thread // that has the connection lock gets a chance at the endpoint lists. connectionsMutex.Signal(); PThread::Sleep(20); connectionsMutex.Wait(); } return NULL; The code try sleep for 20 milliseconds while the connectionsMutex is unlocked, letting the other thread that hold the connection a chancee to use the endpoint lists, but for each 30 milliseconds cycle, it keeps the endpoint lists locked for 10 milliseconds. Attached a trivial fix. Best Regards, Nir Soffer

Hi, First, I would like to thank Packetizer for continuing the open h323 development. Ptlib/h323plus have big set of functions, but I'm not able to find the right one I need. Is there any function to mute/unmute the input sound device while the call is in progress? Any help is greatly appreciated. Marcus

Hello, I would like to use a bluetooth controlled mobile. basically if you connect the mobile to your pc the pc's speaker & mic will become the mobile's speaker & mic. Therefore, I will need to swap the recorder & player device so that h323plus will encode the speaker's audio (player device) and send it to remote endpoint, and decode the microphone's audio (record device) and send it to the local mobile phone. thanks in advance! regards, Eleoson

The CVS code is neutral, compiles in any POSIX compliant system. You will need to inform to the 'configure' program the default system output folder and set proper enviroment variables, some systems need a little more tricks on the config.in file, but not the case of Debian.

IE element decode
by robertp 04 Nov '08

04 Nov '08

lo, i've been harnessing the Q931 class of h323plus to decode packets off the wire, however i'm a little confused as to how h323plus decodes the contents of the information elements which are contained within Q931. i assumed (apparently wrongly) that you would do a check for an element by using Q931.HasIE(), get the byte array of the IE using Q931.GetIE(), then call something like Q931.decodeUserUserIE which returns a structure of some sort which can have methods such as getConferenceGuid() called upon it. I've done the first few steps upto GetIE(), and i now have a PBYTEARRAY of the IE, but i've no idea what to do with it now to decode its contents in a workable, consistent manner. I've poured through the h323+ code, but i cant seem to find where the code deals with this problem. perhaps h323pdu plays a role ?? -- To clarify, i'm sniffing packets off the wire, i.e: mid call, so i'm not an endpoint in the call, rather a onlooker. I don't have transport objects or anything such, i just want to decode the packets and view their contents. - Thanks in advance.

Hi, I have installed openMCU version 2.2.1 (debian repository) OpenH323 version is libopenh323-1.19.1 ( debian repository) OpenMCU starts properly in daemon mode ( openmcu -d ) But netmeeting, Gnomemeeting and xmeeting are not able to connect. Gnomemeeting is giving error as " no comman codec" Can anybody help me on this to resolve this issue? Regards Amogh K This e-mail is confidential and may be legally privileged.

bug in rtp.cxx
by robertp 28 Oct '08

28 Oct '08

line 883 of rtp.cxx is bugged, you're deleting jitter, even if the audio disable has been used for the build. This causes a build error. Also, how reliant is h323plus on the forked sections of ptlib ? Its rather annoying having to build against a customised version. Would it be at all reasonable to make a motion towards merging the ptlib found in other sources such as the ubuntu repositories, and the ptlib given on the h323plus website ? Thanks in advance. - R

RE: [h323plus] How to split audioHi, dansukcu! The best way is deriving H323Codec class and override "write" function (followings for example) and then use it in OpenAudioChannel function. BOOL H323_XXX_Audio_Codec::Write(const BYTE * buffer, unsigned length, const RTP_DataFrame & /*rtpFrame*/, unsigned & written) { ... } BOOL H323_XXX_Audio_Codec::WriteRaw(void * data, PINDEX length) { ... } ... If you want to do more process of the splited audio data, you may also need to implement your own SoundChannel.

Hi, I want to configure openmcu on Debian release lenny I have installed openmcu version 2.2.1. ( debian repository) Manufacturer: Post Increment Version : 2.2.1 System : Linux-i686 2.6.26-1-686 Debian kernel version: Linux linmcu 2.6.26-1-686 #1 SMP Thu Oct 9 15:18:09 UTC 2008 i686 GNU/Linux I am using openh323 version libopenh323-1.19.1 ( debian repository) Openmcu is started properly with openmcu -d ( in daemon mode) But when I try to connect to openmcu through different clients like netmeeting, Gnomemeeting or xmeeting any client is not able to connect.

OpalVideoFormat never instantiated
by Niek Kooij 21 Oct '08

21 Oct '08

Hi, I was looking at the code in h323.cxx function "H323Connection::MergeCapabilities((unsigned sessionID, const H323Capability & local, H323Capability * remote)" OpalVideoFormat & remoteFormat = (OpalVideoFormat &)(remote->GetWritableMediaFormat()); const OpalMediaFormat & localFormat = local.GetMediaFormat(); if (remoteFormat.Merge(localFormat)) { This looks like it would call the "Merge" function of OpalVideoFormat but when debugging it uses the Merge function of the base class OpalMediaFormat. Looking through the code it seems that the class OpalVideoFormat is actually never instantiated. I was thinking of fixing this by making "GetWritableMediaFormat" virtual and reimplementing it in for example "H323VideoCapability" class to create a real OpalVideoFormat instance. I was wondering if anybody knows this code better and could tell if this is a good idea... Greetings Niek

OpenMCU Web page not saving data
by Adrien Rudulier 16 Oct '08

16 Oct '08

OpenMCU's webpage isn't saving the configuration data when I change a value. I did a clean ubuntu install with cvs/svn versions of ptlib, h323plus and openmcu. Does anyone know off the top of their head whether it's a problem with openMCU or should I go talk to the guys at OpalVoip about ptlib? -Adrien __________________________________________________________________ Be smarter than spam.

by quan-xiao-wen 09 Oct '08

09 Oct '08

Hi all: Does H.323plus support H.460.6 now? Is there any tools to simulate H.460.6? thanks George _________________________________________________________________ MSN 中文网，最新时尚生活资讯，白领聚集门户。 http://cn.msn.com

Need tested source code to run an MCU
by Shahzad Abid 22 Sep '08

22 Sep '08

Dear All I am trying since last week to run an openmcu on Centos5 and I have tried almost all the combination of source code available at h323plus.org web site and at source forge.net I need help to install h323plus + openmcu to stablish a video conferacing room. I am successfull installing openh323 + openmcu v2.2.1 on ubuntu but users can't see video but they can hear voice although openmcu's statistics show that clients are Rx/Tx video frames but there is not video at any end. Regards, Shahzad Abid

H323Transport::HandleFirstSignallingChannelPDU crash when connection is NULL
by Nir Soffer 21 Sep '08

21 Sep '08

In H323Transport::HandleFirstSignallingChannelPDU, if NULL connection is returned from endpoint.OnIncomingConnection, the code try to send a release complete to the other side. However, line 1292 is not going to work (the connection is NULL): releaseComplete.Write(*this,*connection); To fix this, I added a Write method which does not accept a connection. Note that the new method duplicate the code from the version that accept a connection - I did not have to time to do it properly. The patch is created against version 1.20.2-alpha2. I verifyed that the issue still exists in the trunk. http://h323plus.cvs.sourceforge.net/h323plus/h323plus/src/transports.cxx?vi…

OpenMCU and XMeeting

I'm having trouble with XMeeting and OpenMCU. XMeeting connects fine intially, but if another h.323 client joins the session, XMeeting disconnects and OpenMCU crashes. Here's what I get at the console for OpenMCU: *** glibc detected *** openmcu: free(): invalid pointer: 0x098912c8 *** ======= Backtrace: ========= /lib/libc.so.6[0xb49ac1]

Thanks a lot Robert for your prompt response. I got confused with your answer. Actually I posted 2 questions so the answer if of which question. The 2 questions are Actually I am looking for error codes in H323 protocols. 1) In H225/Q931 what could be the error codes. Is these error codes comes along with the last message "Release complete message" ? are in between the call.I am able to find these kind of codes specifically in SIP with the response messages with their numbers(Ex:400,500,..),similarly the case with the MGCP protocol.But,I am very much confused with the H.323. 2)What could be the case with the H.245 protocol.

Re: [h323plus] Multicast
by Troy 28 Aug '08

28 Aug '08

Thanks for your input Marcos. I have already looked at OpenMCU but it seems to be too different from what is required for a decentralised conference. As I recall, the signalling involved in OpenMCU is the default behaviour of the base classes for the most part. It wasn't clear to me how to change the signalling to identify distributed multicast but I'm still researching this. But the biggest question I have is how difficult it will be to add multicast capability to the library. Is it as simple as joining a multicast group if the network address is a multicast address and having everything else basically just work (same code to send/receive on an established multicast socket as for a UDP unicast socket) or is there more to it than that... maybe some additional management associated with H.323/H.245/H225.0/???? under this circumstance? So nobody else can provide any pointers/opinions? Troy.

Multicast
by Junk-Mail Wastebasket 20 Aug '08

20 Aug '08

Greetings H323Plus devs. I have need of an ability to support a conference where each end-point can/will manipulate the audio stream coming from every other end-point based on some data associated with each end-point. To me, it seems like each end-point should multicast the audio stream and possibly the data that each other end-point will use to modify the audio stream. Each end-point should listen for multicasts associated with the conference and modify and mix the streams as required based on the data. From my internet searches, this seems to be more or less the classic decentralised/distributed multipoint conference. I have attempted to search the mailing list archives and code for how to do this with H323 Plus and have found that the capability appears to be lacking. Although I am willing to work on developing this capability, I am far from expert on H323 (Plus or otherwise) or VoIP and would need some strong pointers from those of you who are expert. I would appreciate some input on how best to proceed to get the functionality for which I'm looking. Your suggestions would be most welcome, Troy.

Bitrate Fluctuations
by Adrien Rudulier 19 Aug '08

19 Aug '08

When I am connected to OpenMCU using PVX, I notice that the bitrate coming from OpenMCU varies quite a bit. I have the bitrate set to 1920 Mbps but actual call rate is 1856 and the actual bitrate bounces sporadically never hitting the maximum bitrate consistently. Sometimes it goes above the call rate and then back down. Is this something that H323+ handles or is this handled by the codec? __________________________________________________________________ Yahoo!

Shutting down a call manually in OpenMCU
by Adrien Rudulier 06 Aug '08

06 Aug '08

I am trying to manually remove members from a conference from the status web page but I am having troubles closing down the connection properly. I have access to the conference manager and the conference connection. When I call H323Connection::ClearCall(), it severs the connection to the endpoint and the member is removed after ConferenceManager::RemoveMember is called but there is a segmentation fault because the logical channel threads are still running. I keep getting the following assertion failure: 2008/08/06 15:26:39.089 HTTP Service:0xb50f9b90 Message Assertion fail: Transport thread did not terminate, file transports.cxx, line 1355, Error=107 I was wondering if anyone knows how to close down a call properly. __________________________________________________________________ Yahoo!
