Free conferencing software for linux

Konference is (or better: will be) a video-conferencing application for KDE. Since the rewrite (2005/01/25) it supports SIP as the signalling protocol. No longer H323 folks.
Enhancements:
- Added support for transmitting an image instead of video, added support for Arts, fixed various segfaults and reworked configure-dialogs a bit

Fenice is a multimedia streaming server compliant with the IETFs standards for real-time streaming of multimedia contents over Internet. Fenice implements RTSP - Real-Time Streaming Protocol (RFC2326) and RTP/RTCP - Real-Time Transport Protocol/RTP Control Protocol (RFC3550) supporting the RTP Profile for Audio and Video Conferences with Minimal Control (RFC3551).
Fenice supports the following encoding standards:
Audio
- MP3 (MPEG-1 Layer III) (RFC3119)
- OGG/Vorbis (work in progress)
Video
- MPEG-1/2 (RFC2250)
- Preliminary support for MPEG-4 (RFC3016, RFC3640)
- OGG/Theora (work in progress)
The main characteristic of Fenice is that it is adaptable to the state of the network gotten through the technique of the dynamic coding change.
Fenice is also able to manage live streaming sessions using external real-time audio/video encoders such as lame, ffmpeg or mjpeg-tools, even capturing audio and video streams from live-recording remote hosts (with Felice - Fenice Live CEaseless).
Fenice is the worlds first streaming server supporting Creative Commons licensing meta-data for audio/video streaming.
Enhancements:
- Log support via file or sysconfig was added.
- MPEG-4 support was finished, and works best for stored contents.
- The annoying 100% CPU bug was fixed.
- Fenice should now run smoothly and reliably in almost every condition.
- Various bugs were fixed.
- Fenice is GCC4 compatible.

NeMeSI is a streaming client that allows user to enjoy playback of multimedia files with low latency transport over IP-based networks. This software is fully compliant with IETFs standards for real-time streaming of multimedia contents over Internet.
NeMeSI implements RTSP - Real-Time Streaming Protocol (RFC2326) and RTP/RTCP - Real-Time Transport Protocol/RTP Control Protocol (RFC3550) supporting the RTP Profile for Audio and Video Conferences with Minimal Control (RFC3551).
NeMeSI supports the following decoding standards:
Audio
- MP3 (MPEG-1 Layer III) (RFC3119)
- GSM-AMR (3rd generation GSM) (RFC3267)
- OGG/Vorbis (work in progress)
Video
- MPEG-1/2 (RFC2250)
- MPEG-4 (RFC3016, RFC3640) (work in progress)
- OGG/Theora (work in progress)
The main characteristic of NeMeSI is that it is adaptable to the state of the network gotten through the technique of the dynamic coding change.
NeMeSI is the worlds first streaming client supporting Creative Commons licensing meta-data for audio/video streaming.
Enhancements:
- A CLI option was added to force RTP/RTCP UDP ports.
- IPv6 compatibility was improved.
- Preliminary support for MPEG4 was added.
- Conversion to a library was started.
- Fenice is GCC4 compatible.
- Bugfixes were made.

Openbookings.org is an web booking software that allows to manage in an unified way the timetables of all the shared resources of your group, association or company (vehicles, conference rooms, computers, video projectors, cameras, ...).

This software is freely usable/distributable/modifiable subject to respect of its GNU/GPL license conditions. Openbookings.org should work fine with any web server equipped with a PHP module and a MYSQL database.

Installation:

OPENBOOKINGS.ORG QUICKSETUP
(assumes you have PHP, MySQL and an admin tool installed on your server)

1 - MYSQL DATABASE SETUP

Use PhpMyAdmin or your favorite MySQL administration tool to :

- Create a MySQL database named "openbookings" or whatever
- Execute the "database_setup.sql" file to populate the newly created database

2 - CONNECTION SETUP

Open the "config.php" file with a text editor and set the correct values for
the variables $app_path, $db_server_address, $database_name, $db_user, $db_password, $db_connection_type and $time_offset

3 - APPLICATION SETUP

- Access OpenBookings with your web browser (default credentials = admin/admin)
- Click on [Settings] at the bottom of the left menu to access application options
- Click on [Users] at the bottom of the left menu to add authorised users

Thats it.

CCFlauncher is the meta-tool for starting and joining a CCF collaborative computing session. With CCFlauncher you can invite your colleagues/friends to join you in a shared X windows virtual desktop with multiparty audio conferencing, white board, and file sharing in just a few mouse clicks. In this setting, participants interact with each other, simultaneously access and operate computer applications, refer to global data repositories or archives, collectively create and manipulate documents or other artifacts, perform computational transformations, and conduct a number of other activities via telepresence. Research issues addressed in this project include problem solving environments and methodologies for laboratory and instrument-based scientific disciplines, and computer science issues in heterogeneous distributed systems. New approaches are being investigated and developed for fast multiway communication, robust geographically distributed data management methodologies, high-performance computational transforms inlined within collaboration sessions, and related auxiliary issues such as active documents, security, archival storage, and experiment management and control.

The main goal of CCF is to enable the construction of efficient and flexible collaborations. Although we expect that CCF will be useful in a number of scenarios, a guiding principle in its design was to identify and meet the needs of natural science investigators with a diverse set of computing, instrument interfacing, and collaboration requirements. Thus, the primary target domain for CCF is collaborative research in chemistry, physics, and biochemistry, and closely related areas. Research methodology in laboratory and instrument based sciences is increasingly dependent upon computation, interaction, visualization, and data storage/retrieval. The CCF project is investigating and developing innovative enabling technologies to support collaborative, distributed, computer-based problem solving in the natural sciences. The goal is to evolve a virtual environment for distributed computing that integrally supports human AV communication, high performance heterogeneous computing, and distributed data management facilities. Computational transforms, instrument interfacing, data referral, visualization, and collaborative work in chemistry, physics, and biomedical fields will guide the development of methodologies and software tools to facilitate collaborative research.

JWebPresenter project is a bitmap-image based Web presenting system.
It can add a Web extension to your favorite presentation tool, such as PowerPoint, MagicPoint, or Impress.
This is useful in distance learning, meeting, conferencing, and other situations.
It uses bitmap images to avoid compatibility problems. Other features include platform independence and simplicity.
Main features:
- Bitmap image based presenting: Hence we have no compatibility problem related to character corruption, locale, font, ... You can (and you must) use an authoring tool (e.g., PowerPoint, OpenOffice, MagicPoint, etc) to create the slides, then export into images to be presented with JWebPresenter.
- Platform independent: Any system satisfying the requirements should be OK, including Linux PC, Windows PC, PDA Sharp Zaurus SL-C760 (JWebPresenter SS v1.0x).
- Simplicity: I believe simple thing should be done simply. JWebPresenter SS v1.2.1 package (tar.gz) is only 36KB, including source, pre-compiled binarary, document, sample, and a 18KB (uncompressed size) license called GPL!
- Protocol and Image format independent: All protocols and image formats supported by JRE (Java Runtime Enviroment) should be OK.
- Efficience: There is little overhead in JWebPresenter.
