The main creator of the project, and currently (26/10/2001) the unique
developer, is Damien Sandras <dsandras at seconix.com>. He initiated the
project on the 25 december 2000, as a master thesis at the "Université
Catholique de Louvain" in Belgium (http://www.ucl.ac.be). As Damien is the
principal technical answerer in the mailing list, he was the first author, and
right now, principal contributor of this F.A.Q.

GnomeMeeting supports the following audio codecs : LPC10, GSM-06.10, MS-GSM,
G.711-Alaw, G.711-uLaw
GnomeMeeting supports the following video codecs : H.261-QCIF and H.261-CIF
GnomeMeeting supports H.245 Tunnelling, Fast Start, auto answering of incoming
calls, and do not disturb mode
GnomeMeeting can register with ILS directories and browse them to search for
users following several criteria
GnomeMeeting provides an intuitive GUI and is easily configurable.
GnomeMeeting provides an advanced personal settings management.
GnomeMeeting can modify the soundcard and camera settings.
GnomeMeeting provides an animated status docklet that appears in the Gnome or
KDE panel and that can control it.
GnomeMeeting provides internationalization support.

registration.
===============================================================================

No, because Netmeeting asks the ILS directory to list people using Netmeeting
and not other software like GnomeMeeting, but you will be able to see those
people and contact them.
===============================================================================
********** 33..33.. CCaann II sseerrvvee mmyy oowwnn IILLSS ddiirreeccttoorryy?? **********
Yes. The HOWTO here http://www.freesoft.org/software/NetMeeting/ describes how
to set up ILS using OpenLDAP servers. To allow Netmeeting users to see
GnomeMeeting users, it is necessary to modify the netmeeting.perl script to
substitute the search query executed by Netmeeting. A compatible server is
temporarily running at argo.dyndns.org.

tar zxvf GnomeMeeting-0.XX.tar.gz
cd into the directory where you just extracted it
run the ./configure script that supports several parameters :
--prefix=/usr to install it in /usr
--with-ptlib-includes= specifies the location of PTlib headers (for example,/
opt/pwlib/include/ptlib if you extracted PWlib in /opt, default is /usr/
include/ptlib)
--with-ptlib-libs= specifies the location of the PTlib libraries
--with-openh323-includes= specifies the location of OpenH323 headers
--with-openh323-libs= specifies the location of the OpenH323 libraries
For OpenSSL, and LDAP related options, try ./configure --help for more
information.

Yes, provided you have installed the gnome libraries. GnomeMeeting 0.12
provides support for status docklet. It means that Gnome and KDE users will
have the possibility to add a status docklet in their panel.

Yes. It is the Gnome CVS. Gnomemeeting, being natively a Gnome component, you
can find it in the Gnome CVS:
===============================================================================
******** 55..55..11.. LLooggiinn iinnttoo CCVVSS ********
First you need to setup a few environmental variables. The first command you
need is:
$ export CVSROOT=':pserver:anonymous anoncvs gnome org:/cvs/gnome'
You might want to put this in a script.
cvs login
(There is no password, so just press 'Return'.) You only need to run this
command once, not every time you access CVS.
Now grab the Gnomemeeting package.
$ cvs -z3 checkout gnomemeeting
Then, cvs download the last anonymous public version of Gnomemeeting.
Please use the -z3 option to minimize network bandwidth (-z9 eats too much CPU
time - please don't use it).
===============================================================================
******** 55..55..22.. UUppddaattee tthhee ssoouurrccee ffrroomm CCVVSS ********
We assume that you first used all the chapter 4.5.1 procedure.
To update the source, first change directory to where cvs downloaded the
gnomemeeting source
$ cvs -z3 update -Pd gnomemeeting

There can be several causes for that problem :
* You are trying to contact Netmeeting people that have no common codecs
with you. Tell them to install the MS-GSM codec or to enable the G.711
codec.
* Your are using the OSS kernel drivers. Please use the ALSA drivers. Most
of the OSS kernel drivers are not full-duplex, it means that they are
unable to record and play audio at the same time.
* You are natted, and you didn't install the modules.
* You are firewalled and firewall rules drop the audio/video packets.
Please check your firewall rules.

It is not possible. This kind of things is based on the T.120 protocol.
GnomeMeeting currently only supports the H.323 protocol for video-conferencing,
but it doesn't prevent you to trying to implement that protocol or to use
dedicated software like VNC or ICQ for that purpose.

It seems that using the gcc version 2.96, from RedHat (whatever release you
use), can produce severe binary corruption on the SIMD code (Simple Instruction
Multiple Data usually found in MMX acceleration portions, for example). If you
compile from scratch, please use the same vanilla gcc compiler as found on
http://www.gcc.org Gcc v3.01 works fine or use exclusively the -m=i386 and NOT
-m=686

Updated Blocks permits you to choose the number of blocks (that haven't
changed) transmitted with each frame. These blocks fill in the background. If
you choose to transmit 99 blocks that have not changed with each frame, lot of
background blocks will be transmitted with each frame, and the picture will be
more often refreshed. So it is the best quality, but it will need more
bandwidth.

Gnomemeeting (> 0.12) contains support to set the jitter buffer delay and limit
the bandwidth. If you increase the jitter buffer for audio, you should not
loose audio frames.
You can also limit the video bandwidth by using the dedicated option, but the
result will not always be as good as expected. There are other ways to limit
the video bandwidth :
- set the video quality to 31
- set the setting for updated blocks to 2
- limit the transmitted frames per second to 1 FPS

This component of H.323 manages the bandwidth inbound and outbound from the
LAN. Gatekeepers register clients and coordinate communications with other
gatekeepers.
There are four features in a Gatekeeper:
1. Admission control authorizes clients' access to the LAN.
2. Bandwidth control for each network segment managed. Client
3. network addresses are translated so those participants can dial network
locations with aliases (such as e-mail addresses) instead of IP
addresses.
4. Call management monitors H.323 calls, tracks rejected calls, accounts for
use of WAN links and monitors other H.323 Components.

This is the encapsulation of H.245 messages within H.225/Q.931 messages (H.245
tunneling). If you have a firewall and enable H.245 Tunneling, there is one
less TCP port that you need to allow for incoming connections.

Fast Connect is a new method of call setup that bypasses some usual steps in
order to make it faster. In addition to the speed improvement, Fast Connect
allows the media channels to be operational before the CONNECT message is sent,
which is a requirement for certain billing procedures. It was introduced in
OpenH323 version2

Working on: /home/rafa/place/_Datex/FAQ-Gnomemeeting-0.0.6.sgml
1. Generalities1.1. About GnomeMeeting1.1.1. What is GnomemeetingGnomeMeeting is an H.323 compatible client designed for the Gnome desktop. It is compatible with Netmeeting and other H.323 products. 1.1.2. Is it Free Software?As Free Software, you don't have to pay for it, it is free as in free speech and free beer. Yes, it is licensed under the GPL. 1.1.3. What is the LicenseGnomeMeeting is licensed under the GPL and as a special exception, you have permission to link or otherwise combine this program with the programs OpenH323 and Pwlib, and distribute the combination, without applying the requirements of the GNU GPL to the OpenH323 program, as long as you do follow the requirements of the GNU GPL for all the rest of the software thus combined. 1.2. Greetings1.2.1. Who created it?The main creator of the project, and currently (26/10/2001) the unique developer, is Damien Sandras <dsandras at seconix.com>. He initiated the project on the 25 december 2000, as a master thesis at the "Université Catholique de Louvain" in Belgium (http://www.ucl.ac.be). As Damien is the principal technical answerer in the mailing list, he was the first author, and right now, principal contributor of this F.A.Q. 1.2.2. Who made the logo?Carlos Pardo, thanks Carlos. You can visit his website at : http://www.m4de.com 1.2.3. Who made the website?Webdesign was by Cédric Valcke. Feel free to contact him at cvalcke at redoute.fr . The actual website has the same nice graphic design, but is entirely php written (yet another Damien Sandras production). 2. Features2.1. Which audio codecs are supported?At the time of this writing, as of with the v0.12: GnomeMeeting supports the following audio codecs : LPC10, GSM-06.10, MS-GSM, G.711-Alaw, G.711-uLaw 2.2. Which video codecs are supported?GnomeMeeting supports the H.261 video codecs (QCIF and CIF sizes) 2.3. Features.GnomeMeeting supports the following audio codecs : LPC10, GSM-06.10, MS-GSM, G.711-Alaw, G.711-uLaw GnomeMeeting supports the following video codecs : H.261-QCIF and H.261-CIF GnomeMeeting supports H.245 Tunnelling, Fast Start, auto answering of incoming calls, and do not disturb mode GnomeMeeting can register with ILS directories and browse them to search for users following several criteria GnomeMeeting provides an intuitive GUI and is easily configurable. GnomeMeeting provides an advanced personal settings management. GnomeMeeting can modify the soundcard and camera settings. GnomeMeeting provides an animated status docklet that appears in the Gnome or KDE panel and that can control it. GnomeMeeting provides internationalization support. For the most recent feature updates, please see http://www.gnomemeeting.org/features.php 2.4. Does it work with Netmeeting?GnomeMeeting works with Netmeeting 3.01 and even with Netmeeting for Windows XP. 3. ILS directory concerns3.1. Can I register to ILS directories ?Yes, but some directories give error messages and deny GnomeMeeting registration. 3.2. Will Netmeeting users be able to see me ?No, because Netmeeting asks the ILS directory to list people using Netmeeting and not other software like GnomeMeeting, but you will be able to see those people and contact them. 3.3. Can I serve my own ILS directory?Yes. The HOWTO here http://www.freesoft.org/software/NetMeeting/ describes how to set up ILS using OpenLDAP servers. To allow Netmeeting users to see GnomeMeeting users, it is necessary to modify the netmeeting.perl script to substitute the search query executed by Netmeeting. A compatible server is temporarily running at argo.dyndns.org. 4. Hardware concerns4.1. Do I need a webcam to run GnomeMeeting?No, a working soundcard is enough. 4.2. Which type of camera can I use with GnomeMeeting?Every camera supported by the Linux kernel and that understands the Video4Linux API (Philips webcams, Creative webcams, and many others...) Please mail r_pinilla at yahoo.com so that we can build a list of supported webcams and give an appreciation of the webcam quality when used together with GnomeMeeting. Please insert the string “ GM-webcam “ in your subject. 4.2.1. Resources for Philips webcamURLs: Philips USB webcams: http://www.smcc.demon.nl/webcam/ http://daimon.free.fr/linux/trucs/videocam.html Compatibility: Good Tips & tricks: Supported models: all the 6XX and 7XX USB series are known to work. 5. Software concerns5.1. Which libraries do I need to run it?You will need : the standard Gnome Libraries : http://www.gnome.org the OpenH323 library : see the download section of this site the PWLib library : see the download section of this site the OpenLDAP library : included in your distribution, or http://www.openldap.org 5.2. How can I compile GnomeMeeting?Simply use the binaries from your distribution, the ones in the download section, or : As root, follow the steps : 5.2.1. Compile pwlibExtract it: tar xvzf pwlib_X.X.X.tar.gz
export PWLIBDIR=<the directory where you extracted pwlib>
cd $PWLIBDIR
make opt
And then do the following : cp -d $PWLIBDIR/lib/*so* /usr/local/lib
ln -s /usr/local/lib/libpt_linux_x86_r.so.X.X.X /usr/local/lib/libpt.so
Then, add /usr/local/lib to /etc/ld.so.conf and run ldconfig 5.2.2. Compile Open H323.Download it either from http://www.gnomemeeting.org/downloads or from http://www.openh323.org/code.html extract it :
tar xvzf openh323_X.X.X.tar.gz
export OPENH323DIR=<the directory where you extracted openh323>
cd $OPENH323DIR
make opt$OPENH323DIR/lib/*so* /usr/local/lib
cp -d $OPENH323DIR/lib/*so* /usr/local/lib
ln -s /usr/local/lib/libh323_linux_x86_r.so.X.X.X /usr/local/lib/libopenh323.so
Then, run ldconfig. If you have any problem, please have a look at openh323 FAQ : http://www.openh323.org/ 5.2.3. Compile OpenLDAPCheck if it is installed in /usr/lib/ or /usr/local/lib (ls /usr/lib/libldap*) Installation is beyond the scope of this FAQ. Check http://www.openldap.org for more information on how to install the OpenLDAP libraries. 5.2.4. Compile GnomemeetingDownload it on http://www.gnomemeeting.org/downloads Extract it: tar zxvf GnomeMeeting-0.XX.tar.gz
cd into the directory where you just extracted it run the ./configure script that supports several parameters : --prefix=/usr to install it in /usr --with-ptlib-includes= specifies the location of PTlib headers (for example,/opt/pwlib/include/ptlib if you extracted PWlib in /opt, default is /usr/include/ptlib) --with-ptlib-libs= specifies the location of the PTlib libraries --with-openh323-includes= specifies the location of OpenH323 headers --with-openh323-libs= specifies the location of the OpenH323 libraries For OpenSSL, and LDAP related options, try ./configure --help for more information. make
make install
You should have the gnomemeeting executable available. 5.2.5. **Error**: You must have `intltool' installed to compile gnomemeeting.Get ftp://ftp.gnome.org/pub/GNOME/stable/sources/intltool/intltool-0.12.tar.gz (or a newer version if it is available) 5.2.6. I'm very lazy, dont you have an automated script.Yes, we have. #!/bin/sh

Stay tuned, more to come. 5.3. Can I use another version of OpenH323 and PWlib than the versions provided in the download section?Yes, if these versions are newer. Don't use old version of the libraries. 5.4. Does it run under KDE?Yes, provided you have installed the gnome libraries. GnomeMeeting 0.12 provides support for status docklet. It means that Gnome and KDE users will have the possibility to add a status docklet in their panel. 5.5. Is there a CVS repository?Yes. It is the Gnome CVS. Gnomemeeting, being natively a Gnome component, you can find it in the Gnome CVS: 5.5.1. Login into CVSFirst you need to setup a few environmental variables. The first command you need is: $ export CVSROOT=':pserver:anonymous anoncvs gnome org:/cvs/gnome'
You might want to put this in a script. cvs login
(There is no password, so just press 'Return'.) You only need to run this command once, not every time you access CVS. Now grab the Gnomemeeting package. $ cvs -z3 checkout gnomemeeting
Then, cvs download the last anonymous public version of Gnomemeeting. Please use the -z3 option to minimize network bandwidth (-z9 eats too much CPU time - please don't use it). 5.5.2. Update the source from CVSWe assume that you first used all the chapter 4.5.1 procedure. To update the source, first change directory to where cvs downloaded the gnomemeeting source $ cvs -z3 update -Pd gnomemeeting
6. Getting it to work behind a firewallH323 relies on a very special protocol behaviour that uses several ports : H.323 uses/relies on the following data streams: Port Description 389 Internet Locator Server (TCP) 522 User Location Server (TCP) 1503 T.120 Protocol (TCP) 1720 H.323 (H.225 call setup, TCP) 1731 Audio call control (TCP) Dynamic H.245 call control (TCP) Dynamic RTCP/RTP streaming (UDP) 6.1. For 2.2 kernelsThe appropriate module can be found on : http://www.coritel.it/coritel/ip/sofia/nat/nat2/nat2.htm A little Howto: http://www.linux-sottises.net/en_themasq.php (english) The same Howto in French http://www.linux-sottises.net/themasq.php 6.2. For 2.4 kernelsThe newnat netfilter modules can be found on: http://www.kfki.hu/˜kadlec/sw/netfilter/ 7. Troubleshooting7.1. I Don't have any /dev/video* device ! What can I do ?Create it by hand, being root: localhost:/dev# mknod c 81 0 /dev/video0 localhost:/dev# mknod c 81 1 /dev/video1 localhost:/dev# mknod c 81 2 /dev/video2 You should create a symlink from /dev/video to the one you want used first localhost:/dev# ln -s /dev/video0 /dev/video 7.2. I have Permissions problems with /dev/video*You should have the following permissions in your /dev/video* devices lrwxrwxrwx 1 root video 11 Aug 25 02:37 video -> /dev/video0 crw-rw-r-- 1 root video 81, 0 Aug 25 02:37 video0 crw-rw-r-- 1 root video 81, 2 Aug 25 02:18 video2 crw-rw-r-- 1 root video 81, 1 Aug 25 02:18 video1 So, if you haven't done it yet, add your username at the end of the 'video' line in the file '/etc/group'. you should see the line: video:x:44:username Then, give the necessary permissions to the devices: chown root.video /dev/video0 chown root.video /dev/video1 chown root.video /dev/video2 chmod u=rw g=rw /dev/video0 chmod u=rw g=rw /dev/video1 chmod u=rw g=rw /dev/video2 7.3. God ! Why does-it function so bad?The camera occasionally starts up in a higher resolution mode and I only see 1/4 of its field of view in the small window mode. Are you sure that your driver support 176x144 as capture size? Try to look about that in the doc. 7.4. I can see people, but I do not hear them, and they don't hear me.There can be several causes for that problem :
7.5. Video test is working, but people do not see me.Netmeeting seems to have problem if you choose to send images with size being set to 'Large'. You forgot to enable video transmission in the settings. 7.6. How can I send a test picture to the remote endpoint if I have no webcam?You can always select "Enable Video Transmission". When clicking on Apply, you will get a warning but a test picture will be sent to the remote endpoint during calls. 7.7. How can I share my desktop or make a text chat with Netmeeting?It is not possible. This kind of things is based on the T.120 protocol. GnomeMeeting currently only supports the H.323 protocol for video-conferencing, but it doesn't prevent you to trying to implement that protocol or to use dedicated software like VNC or ICQ for that purpose. 7.8. I have trouble compiling (whatever Gnomemeeting software component) with gcc 2.96.It seems that using the gcc version 2.96, from RedHat (whatever release you use), can produce severe binary corruption on the SIMD code (Simple Instruction Multiple Data usually found in MMX acceleration portions, for example). If you compile from scratch, please use the same vanilla gcc compiler as found on http://www.gcc.org Gcc v3.01 works fine or use exclusively the -m=i386 and NOT -m=686 References: http://gcc.gnu.org/gcc-2.96.html http://www.redhat.com/support/errata/RHBA-2000-132.html 8. Tuning Questions8.1. What do the settings for video quality from 1 to 31 means?1 is best quality, 31 is bad quality, but uses less bandwidth. 8.2. What about the settings for updated blocks?Updated Blocks permits you to choose the number of blocks (that haven't changed) transmitted with each frame. These blocks fill in the background. If you choose to transmit 99 blocks that have not changed with each frame, lot of background blocks will be transmitted with each frame, and the picture will be more often refreshed. So it is the best quality, but it will need more bandwidth. 8.3. I prefer realtime-Sound/Bad-Video than Realtime-Video/Bad-Sound.Gnomemeeting (> 0.12) contains support to set the jitter buffer delay and limit the bandwidth. If you increase the jitter buffer for audio, you should not loose audio frames. You can also limit the video bandwidth by using the dedicated option, but the result will not always be as good as expected. There are other ways to limit the video bandwidth : - set the video quality to 31 - set the setting for updated blocks to 2 - limit the transmitted frames per second to 1 FPS 8.4. What is the best audio codec supported by GnomeMeeting?GSM. GSM is not supported by Microsoft Netmeeting, but you can add it to Netmeeting. Just download the executable in the download section of http://www.gnomemeeting.org 8.5. What is a Gatekeeper and what does it do?This component of H.323 manages the bandwidth inbound and outbound from the LAN. Gatekeepers register clients and coordinate communications with other gatekeepers. There are four features in a Gatekeeper:
8.6. What is H.245 Tunneling?This is the encapsulation of H.245 messages within H.225/Q.931 messages (H.245 tunneling). If you have a firewall and enable H.245 Tunneling, there is one less TCP port that you need to allow for incoming connections. 8.7. What is fast start?Fast Connect is a new method of call setup that bypasses some usual steps in order to make it faster. In addition to the speed improvement, Fast Connect allows the media channels to be operational before the CONNECT message is sent, which is a requirement for certain billing procedures. It was introduced in OpenH323 version2 |
