confiance-devel Mailing List for CONFIANCE

Hi !!

I am Juanvi Martínez and I am new (and maybe alone) in this mailing  
list.

I'm having a problem when running Confiance. When I try to execute it,  
I always get the error "Couldn't open the codec to open the logo image  
file...".

I have tried to download the latest FFMPEG version from its SVN  
repository and recompile it, but the error still appears.

Maybe the problem is something related with CODEC_FLAG_H263P_AIC, not  
supported anymore in ffmpeg, but I changed in cvm_session.c the line  
that refers to it to fit with the new supported codec  
(CODEC_FLAG_AC_PRED) and I get the same error.

Does anyone have a solution to this??

Thank you !!! :)

Hi Sher,

Minisip or any other BFCP-enabled client is only needed for enhanced  
Confiance conferences (i.e. those with the new protocols we  
implemented). The patch also allows normal meetme conferences to take  
advantage of the video features: enabling video sources is however  
left to other means (a console command, in this case), considering  
that no moderation protocol is involved.

About the Grandstream phone, it will work if you'll just use  
videoswitching between them. The available VideoMixer doesn't support  
CIF resolutions, which is how Grandstream sends video. Videoswitching  
doesn't involve transcoding and composition (it's just a forwarding of  
incoming frames from the enabled source to the other destinations), so  
it should work just fine.

Regards,
Lorenzo

Hi. I'd like to configure confiance with asterisk. Would this allow me  
to have a video conference call using the grandstream gxv3000 video  
phone?

Is the minisip required if I'll be using the gxv3000 for making my  
video conference calls?

Thanks,

Sher

Hello!
I'm one of the Asterisk developers, looking at your patches for  
Asterisk.

I'm trying to sort out the licensing for your libraries, but it's hard  
to find out.
If your libraries are licensed under GPL, we can't include your stuff
under our dual license. If you license under lgpl or BSD, there's no  
problem.

Can you please confirm the license for libraries?

Thanks,
/Olle

A paper on CONFIANCE and DCON has been recently presented at the IPTComm 
2007 conference (Principles, Systems and Applications of IP 
Telecommunications) in New York (http://iptcomm.org). After the 
discussion of the paper, which described the scalability enhancements 
DCON can offer, a demo of the described work has been successfully 
arranged for all the interested attendees.
You can have a look at all the presented work (slides, proceedings, and 
a couple of videos as well) on the documentation page 
(http://confiance.sf.net/doc).

A user-friendly, interactive, installer script for CONFIANCE is now availab=
le.
It allows an automatic retrieval, compilation and installation of all the=20
needed pieces of the framework (Asterisk, Minisip, BFCP, MSRP, Videomixers=
=20
and both client and server side patches), without having to take care of ea=
ch=20
one separately. The script is interactive, which means you can choose what =
to=20
compile and what not (for example if you've already installed a component).
You can get the gz-compressed script from the download page:

Exciting news in CONFIANCE!
The new release introduces support for video mixing and transcoding 
functionality, so that to provide continuous video presence in 
conferences. To do so, CONFIANCE can rely on two different videomixers:

	* CONFIANCE VideoMixer (http://confiance.sourceforge.net/?q=node/21), a 
work we're carrying on ourselves, and which you can get on the CONFIANCE 
homepage;
	* Sergio Garcia Murillo's VideoMixer, an open source videomixer 
available on http://sip.fontventa.com/.

Both the videomixers are optional, and do not depend on each other. This 
means that you can choose to enable support for both, for only one, or 
for none if you're just interested in the already provided basic 
videoswitching. Instructions on how to enable support for the 
videomixer(s) are provided in the CONFIANCE installation guide.

Though both the videomixers are early works and in a beta stage, they 
both already work quite fine, and have support for a range of codecs. 
Specifically, the CONFIANCE VideoMixer currently provides:

	* adaptive layouts according to how many active video sources are 
feeding the mix;
	* continuous presence for up to 8 users (this can be easily enhanced by 
adding new layouts in the code);
	* a static logo when no video sources are active;
	* support for H.261, H.263 and H.263+ (QCIF only for the moment, and 
H.261 support is still quite buggy).

Currently, only one global layout is available for all users in the same 
conference: support for customized layouts will be added in the future. 
Any kind of feedback and/or comment/suggestion upon the current work 
will be more than welcome, and will help us enhancing its functionality.

To know more about the VideoMixer Sergio Garcia Murillo wrote, visit his 
website at http://sip.fontventa.com/, and follow the discussion on the 
Asterisk-video mailing list.

That said, you can get the updated release of CONFIANCE, which envisages 
support these VideoMixers, on the project download page:

	* 
http://prdownloads.sourceforge.net/confiance/confiance_wip_server-0.7.tar.gz?download, 
the server side of the platform;
	* 
http://prdownloads.sourceforge.net/confiance/confiance_wip_client-0.7.tar.gz?download, 
the client side of the platform;

and the CONFIANCE VideoMixer here:

	* 
http://prdownloads.sourceforge.net/confiance/confiance_videomixer-0.1.tar.gz?download.


To get Sergio Garcia Murillo's VideoMixer:

	* svn co http://sip.fontventa.com/svn/mcu

You'll need xmlrpc-c 1.1 to compile it.

An article about DCON (http://dcon.sf.net) has been recently published 
on the March issue of the IEEE Communications Magazine:

	A. Buono, S. Loreto, L. Miniero, S.P. Romano "A distributed IMS enabled 
conferencing architecture on top of a standard centralized conferencing 
framework", IEEE Communications Magazine vol.45, No 3, March 2007 
(http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=4150583, requires 
IEEE subscription or membership)


A demo of the DCON framework in action has also been successfully 
presented at the latest IEEE INFOCOM 2007 conference, the 26th Annual 
IEEE Conference on Computer Communications in Anchorage, Alaska. You can 
get the presented brochure from the Documentation page 
(http://confiance.sourceforge.net/?q=node/3).


Coming to the future events, a paper on CONFIANCE and DCON has been 
accepted at the upcoming IPTComm 2007 conference (Principles, Systems 
and Applications of IP Telecommunications, http://iptcomm.org/). Besides 
the discussion of the paper, which describes the scalability 
enhancements DCON can offer, a demo of the described work will be 
presented as well, so in case you're in New Work on the 19th and 20th 
June pay us a visit!

To conclude, a paper more focused on CONFIANCE has been accepted at the 
upcoming NEW2AN 2007 conference (The 7th International Conference on 
Next Generation Teletraffic and Wired/Wireless Advanced Networking, 
http://www.new2an.org/). The paper will be presented ad discussed in 
September in St.Petersburg.

CONFIANCE version 0.6 has just been released:

     * 
http://prdownloads.sourceforge.net/confiance/confiance_wip_server-0.6.tar.gz?download, 
the server side of the platform;
     * 
http://prdownloads.sourceforge.net/confiance/confiance_wip_client-0.6.tar.gz?download, 
the client side of the platform.

Starting from this release, the stable 1.4.x versions of Asterisk will 
be used as a base, instead of the SVN one, to ease versioning, debugging 
and patching.

Besides, as already announced, BFCP has been made a separate library, 
which will then have to be installed before CONFIANCE.

Finally, CONFIANCE has been enriched with MSRP (Message Session Relay 
Protocol) chatroom functionality. MSRP, as BFCP, is an external library 
we wrote exploited by both client and server sides of CONFIANCE.

The work on CONFIANCE is going on.
In the meanwhile, we've opened two new projects on Sourceforge. They 
host the libraries we implemented, and on which CONFIANCE relies to take 
advantage of their features, specifically:

     * libBFCP (http://sourceforge.net/projects/libbfcp), the libraries 
implementing the BFCP (Binary Floor Control Protocol) stack;
     * libMSRP (http://sourceforge.net/projects/libmsrp), the libraries 
implementing the MSRP (Message Session Relay Protocol) stack, which is 
currently being integrated within CONFIANCE to add chatroom 
functionality to XCON conferences.

Both the libraries are open source (GPL license), so you're encouraged 
to use them in your projects if you find them useful.
Any feedback upon them will be more than welcome.

A new update on CONFIANCE is available on the project download page:

     * 
http://prdownloads.sourceforge.net/confiance/confiance_wip_server-0.5.tar.gz?download, 
the server side of the platform;
     * 
http://prdownloads.sourceforge.net/confiance/confiance_wip_client-0.5.tar.gz?download, 
the client side of the platform.

Minor updates include several bugfixes, a verbose debug level to 
optionally limit the amount of console notifications about what's 
happening, and enhancements upon the XCON/DCON integration support.

As a new feature, instead, videoswitching has been made available for 
basic MeetMe conferences as well, and not only for XCON/DCON 
conferences. However, since in MeetMe conferences the video source 
switching cannot be accomplished by means of the BFCP way of 
coordinating access to resources, it can currently be realized only 
using a new dedicated console command, 'videoswitch', as a 
proof-of-concept. Checkout our mail on the Asterisk-video mailing list 
for more details upon the feature 
(http://lists.digium.com/pipermail/asterisk-video/2007-January/000389.html).

Finally, as a major enhancement upon the previous version of the 
platform, the whole BFCP stack (both message processing and behaviour 
layers) has been refined, fixed and, most importantly, enriched with 
support for BFCP over TLS as stated in the RFC4582. However, support for 
BFCP over TLS has to be explicitely enabled and appropriately configured 
in the CONFIANCE configuration file in order to work properly, since by 
default the Floor Control Server will keep on exploiting simple TCP 
connections for BFCP communication. No configuration is needed on the 
client side, since the appropriate transport method for TCP will be 
automatically exploited consequently to SIP/SDP negotiation with the focus.

The standalone BFCP updated libraries can be obtained as usual on the 
project download page:

     * 
http://prdownloads.sourceforge.net/confiance/confiance-v7bfcp-only-05.tar.gz?download.

To compile this version of the libraries for Windows you'll not only 
need the Win32 porting of the Pthreads, which you can get on the 
official page (http://sourceware.org/pthreads-win32/), but also the 
Win32 porting of OpenSSL, which is needed for BFCP over TLS support: you 
can get it on the Win32 OpenSSL Installation Project 
(http://www.slproweb.com/products/Win32OpenSSL.html) or compile it 
yourself out of the code on the official page (http://www.openssl.org/).

Hi folks,
for some time now I have been lurking on your list and homepage. I’m 
very interested in your project and would like to help.
Since I would like to get to know the project better, I thought it would 
be a good start to setup a MediaWiki to manage user documentation and 
developer docs.

It would help me to learn about how to contribute and also would help 
you and the users. Some things I could do (but I am open for suggestions):
- Collect information about project member's interests.
- Remind of certain events: release, urgent documentation updates, 
long-term goals.
- Keep an eye on the project documentation and guides.
- Be an active guide for newcomers.
- Dig up or re-introduce ideas which otherwise would get lost in 
mailing-list conversations.
- Write down the results of decisions and ToDo items.

So maybe these activities can be called “housekeeping” of information 
that already exist? Of course, the housekeeper does not have any higher 
privileges: Changes to every recorded statement can be made by each 
project member (it’s a wiki) and the housekeeper does not make decision, 
but rather collects them.
The usual work of the housekeeper will consist of an in-depth study of 
the mailing-list and homepage but also other communication channels.

After building up the Wiki I’d like to fill in all information that is 
available in the current mailinglist and homepage. In three months we 
can look at the results of my work and poll whether to continue it or 
not. During these 3 months everybody can contribute to the effort, but 
of course nobody has to.

I hope this introduction gave you enough information to get a picture of 
what I want to do. Any comments or criticism are welcome.

Kind regards
B. Cybot

After some weeks of silence, we can finally provide you with many=20
interesting news.
The SVN branch containing our server-side addons for Asterisk has=20
changed location, which means that from now on you'll have to change the=20
address to access it:

    * svn co http://svn.digium.com/svn/asterisk/team/group/xcon_bfcp

The updates upon the Work in Progress version of our platform are as=20
usual available on the project download page:

      the client side of the platform.

Besides fixing some issues that have been found, the most notable update=20
on the platform is its integration with another project we're carrying=20
on, Distributed Conferencing (DCON). DCON enables the distribution of=20
XCON conferences transparently to users, by means of appropriate=20
information spreading and protocols dispatching. Checkout the related=20
page on Sourceforge for more details (http://dcon.sourceforge.net/), as=20
documentation, slides and IETF drafts.

Finally, a Win32 porting of the BFCP libraries has been made available.=20
The libraries have been tested with MingW, but should work fine with any=20
other compiler. Besides, Java bindings for both Linux- and Windows-based=20
systems have been made available as well, through a Java Native=20
Interface (JNI) (thanks to Amato Sorrentino for that). You can get both=20
the packages on the project download page:

    * http://prdownloads.sourceforge.net/confiance/confiance-v7bfcp-only-=
04.tar.gz?download,
      the C libraries;
    * http://prdownloads.sourceforge.net/confiance/confiance-v7bfcp-only-=
04-JNI.zip?download,
      the Java bindings for the libraries.

To compile the libraries for Windows you'll need the Win32 portings of=20
the Pthreads, which you can get on the official page=20
(http://sourceware.org/pthreads-win32/). Please note that both the=20
portings are experimental and not fully tested yet, so please let us=20
know if you meet any strange behaviour when using them.


That's all for now, let us know what you think about the work made on=20
the platform so far. If you encounter any problem using it or installing=20
it, feel free to contact us. As usual, any comment, feedback and=20
suggestion will be more than welcome.

After some weeks of silence, we can finally provide you with many interes=
ting news.
First of all, the WIP on Confiance has gone on despite the lack of update=
s on the site, and is now quite stable. Besides, a separate branch contai=
ning our server-side addons for Asterisk has been made available (many th=
anks to Russell for that), which means you can access it via SVN to alway=
s get up-do-date revisions:

    * svn co http://svn.digium.com/svn/asterisk/team/russell/xcon_bfcp

A patch to the main trunk of Asterisk is available anyway, in case you pr=
efer manually applying it.
The updates upon the Work in Progress version of our platform are as usua=
l available in the project download page:

    * confiance_wip_server-0.3.tar.gz, the server side of the platform;
    * confiance_wip_client-0.3.tar.gz, the client side of the platform.

Besides fixing some issues that have been found, we enhanced the Conferen=
ce Session Management protocol (XconScheduler) with some functionality, t=
he most important being the newly introduced use of Blueprints and Templa=
tes (which can be used to create new conferences out of default settings)=
 and the possibility for the user to set a Subject for the conferences sh=
e/he might want to create. Finally, great work has been done so far to in=
tegrate the Focus (Asterisk) with a WebServices-enabled conference sessio=
n management protocol: the work is in a very advanced state, and news on =
it will soon be published on this page, so come back soon for updates.

About the client side, Minisip's GUI has been enhanced and made clearer, =
by placing BFCP management graphical interfaces in a separate window. Fur=
thermore, to take advantage of the newly introduced functionality provide=
d by the Focus, new methods have been added to the protocol:

    * QueryBlueprints and QueryTemplates, to access the available Bluepri=
nts and Templates offered by the conferencing system, and eventually use =
them to create new conferences;
    * QueryUsers, to get the list of all users currently participating to=
 a conference.

All the methods have an "alias" in the Asterisk Manager Interface too, to=
 allow asynchronous events notifications.


That's all for now, let us know what you think about the work made on the=
 platform so far. If you encounter any problem using it or installing it,=
 feel free to contact us. As usual, any comment and suggestion will be mo=
re than welcome too.

Since both the CONFIANCE client and server WIP files come in the form of 
source diff files (being them based on existing, opportunely modified, 
open-source components), we made available a separate tarball package 
too which only contains the BFCP (Binary Floor Control Protocol) 
management libraries. The available libraries, which have been 
implemented according to the v07 draft specifications of the BFCP 
(attached), are:
* BFCP_library, the upper layer library managing all the BFCP behaviour 
(e.g. connection between Floor Control Server and Floor Control 
Participants, advanced floor management, and so on);
* BFCP_messages_processing, the lower library taking care of both 
building and parsing of the BFCP binary messages out of the required 
arguments (included in BFCP_library, so only use it if you want to 
implement a BFCP behaviour on your own).
The package 
(http://prdownloads.sourceforge.net/confiance/confiance-v7bfcp-only.tar.gz?download) 
can be found in the project download page.

An update upon the Work in Progress version of our platform is now 
available in the project download page.
The update fixes many issues that have been found by testing both the 
server and client sides of the framework. Besides, the client side of 
the the Scheduler Text Protocol component has been enriched with two new 
interfaces:
* SetChair, to let the conference administrators choose a chair 
moderator for a specific floor in the conference itself;
* Unregister, to enable the conference administrators to unregister a 
previously created conference, so that to definitely remove it from the 
conference (if the conference is currently active, it is destroyed).
Both the new features require the administrator's password to be called, 
since only the conference creators will be allowed to edit existing 
conference settings.
Let us know what you think about the platform and if you encounter any 
problem using it, any comment and suggestion will be more than welcome.
