Besides,I also can not find the dshow.h. Who can help me ?thanks! 2008-11-28 JobsGuo(Guo Huayong) Mobile：13918103120 QQ ： 360480589 MSN ： ghyhust< at >hotmail.com JobsGuo(Guo Huayong 2008-11-28T05:56:33 http://comments.gmane.org/gmane.comp.telephony.h323plus/331 Hello...

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 ?? robertp 2008-11-04T12:53:14 http://comments.gmane.org/gmane.comp.telephony.h323plus/326 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.

Amogh.Kulkarni< at >shinsei-it.com 2008-11-04T04:05:33 http://comments.gmane.org/gmane.comp.telephony.h323plus/324 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 robertp 2008-10-24T10:25:28 http://comments.gmane.org/gmane.comp.telephony.h323plus/319 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. Gnomemeeting is giving error as "no comman codec" What could be the issue? Then I tried to compile audio/video plugins(1.20.0) given by h323plus website.

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...

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.

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.

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!

Adrien Rudulier 2008-08-19T18:38:10 http://comments.gmane.org/gmane.comp.telephony.h323plus/293 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 Junk-Mail Wastebasket 2008-08-18T17:55:19 http://comments.gmane.org/gmane.comp.telephony.h323plus/292 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!
