Hi there,
we are happy to announce our next major release:
NMM 0.8.0 "Rainbow"

The Network-Integrated Multimedia Middleware (NMM) provides an 
architecture that allows to create distributed multimedia application 
easily: local and remote multimedia devices or software components can 
be controlled transparently and integrated into a common multimedia 
processing flow graph. NMM runs under Linux and under Windows, is 
implemented in C++, and distributed under the LGPL. For more 
information, see: http://www.networkmultimedia.org

Furthermore, NMM provides several services which are vital in a 
distributed multimedia environment:
* A scalable distributed registry service which discovers and manages 
available resources, like hardware or software plug-ins, efficiently.  
   In addition it enables distributed applications to access locally 
resources. See 
http://www.networkmultimedia.org/current/Docs/first-steps/index.html and 
http://www.networkmultimedia.org/current/Docs/server-registry/index.html 
for some information and examples.

* For distributed and synchronized play back of audio and/or video, NMM 
provides a distributed synchronization service using the Network Time 
Protocol (NTP). An introduction how to set up NTP for NMM can be found 
here http://www.networkmultimedia.org/current/Docs/ntp/index.html.

* The concept of session sharing allows to share parts of an active 
multimedia session and provides synchronized and distributed media 
playback on various devices within different applications. For more 
information, see 
http://www.networkmultimedia.org/Publications/2003/session-sharing-mips2003.pdf

NEW in this release are:
* Multimedia box:
  - Added first version of a sophisticated transcoding state which 
allows for distributed and parallelized transcoding of arbitrary 
audio/video sources, like files or DVDs. See 
http://graphics.cs.uni-sb.de/NMM/Status/MMBox/Photos/feb2005/index.html 
for some screenshots of this new transcoding state and our new features. 
The key assignemnt of this new state can be found under 
http://graphics.cs.uni-sb.de/NMM/current/Docs/mmboxcontrol/index.html

  - All states provide a color bar to simplify operating by remote 
control. The buttons of this color bar can be controlled by the four 
color buttons of a remote control. The key assignemnt of the color bar 
can be found under 
http://graphics.cs.uni-sb.de/NMM/current/Docs/mmboxcontrol/index.html
  - many minor extensions and bug fixes

* Updated and extended instructions for downloading, installing, and 
testing NMM. See 
http://graphics.cs.uni-sb.de/NMM/Download/index.html#configure for 
further information.
* Added security mechanism to limit read/write access to certain 
directories and users. See step 4 of our extended installation 
instructions for further information.

* Updated the following plug-ins to new library versions. See 
http://graphics.cs.uni-sb.de/NMM/current/Docs/pluginlist/index.html for 
further information.
 - Updated DVDNavReadNode to libdvdnav 0.1.10
 - Updated VorbisEncode/DecodeNode to libogg&libvorbis 1.0.1
* Added TVCardReadNode2 which supports video4linux2 (implemented by  
Andrés Otón)
* Improved automatic plugin loading (run './apps/serverregistry -s)
* Changed plugin management and registration. Now each plugin is stored 
into a separate library (finished update). Plugin developer should read 
our tutorial about "Developing Plug-ins for NMM" 
(http://graphics.cs.uni-sb.de/NMM/current/Docs/plugins/index.html) for 
further information
* Changed installation path of our plugins and libraries into a separate 
nmm sub-directory to avoid congestion of standard library directories.
* many bugfixes in plug-ins and NMM base

Together, the 0.8.0 release consists of several parts:
(1) The NMM-base system
(2) Over 50 plug-ins (called NMM-Nodes)
    that allow to access multimedia devices like
    - Video and Sound boards,
    - TV-tuner and DVB boards
    - CD/DVD drives
    - Firewire devices
    - VISCA cameras
    - ... and many more
    or provide different software processing components like
    - MPEG video decoder/demultiplexer
    - MPEG audio encoder/decoder/demultiplexer
    - Ogg/Vorbis encoder/decoder/demultiplexer
    - DivX encoder/decoder
    - AVI multiplexer/demultiplexer and reader/writer
    - Colorspace converters
    - Video effects
    - Audio filters and visualization
    - ... and many more
    See
http://www.networkmultimedia.org/NMM/current/Docs/pluginlist/index.html.
    for a complete list of supported plugins

(3) The Multimedia-Box application is based on NMM and provides an 
integrated software solution for a Multimedia Home-Entertainment Center 
running on a commodity Linux-PC. Following features are available:
    - CD-Player with CDDB support, DVD-Player with support for menus and 
a Play-list for creation of play lists with all supported media types.
    - CD-Grabber and DVD-Grabber with transcoding capabilities to 
different audio and video formats. Furthermore, the DVD transcoding task 
can transparently be distributed to remote hosts that provide more 
processing power.
    - TV (analog or digital) plus time-shifting. Furthermore, for hosts 
that do not have direct access to a analog or digital TV source (e.g. 
via a PCI board), a remote host can transparently provide this 
functionality.
    - Video recorder functionality and Electronic Program Guide using 
either DVB or XMLTV as data source and simple web interface
    - Sophisticated transcoding functionality for all supported data 
types (like avi, mpeg or even DVDs) that can be parallelized and 
distributed to remote hosts that provide more processing.
    - Multi-tasking: watch TV while transcoding.
    - All controllable with a remote-control (or via keyboard when 
running as standard desktop application)
    - Customizable on-screen display (skinning) with six different 
skins: blue, blues, las_vegas, icon, ct-skin1, ct-skin2.
    - Extensible and configurable application framework (XML)
    - For more information, see:
      http://www.networkmultimedia.org/Status/MMBox/index.html

(4) clic: CommandLine Interaction and Configuration. An application for 
setting up distributed multimedia flow graphs from a high-level
    specification - a so called graph description stored in a .gd-file. 
Many .gd-files are also included that allow - for example - distributed 
grabbing and transcoding DVDs.

(5) some small example applications demonstrating the functionality of 
the plug-ins

(6) A registry service, that administrates all resources available at a 
host. This service can be requested from local or remote applications.

(7) A Qt-application called qregwizard that shows the current status of 
the registry

(8) qcamcontrol: a Qt-application that allows to control local and 
remote Firewire cameras.

(9) All documentation that can also be found online.


This release provides support for gcc 2.95, 3.3 and 3.4. We also provide 
pre-compiled version of external libraries for both gcc 2.95 and gcc 
3.x, please see README in the tar.gz archive. Finally, this release was 
compiled and tested with the following distributions:
    * Debian woody with gcc 2.95.4 and gcc 3.3.1
    * Debian sarge with gcc 3.3.5
    * Debian sid with gcc 3.3.5
    * SuSE 8.2 with gcc 3.3
    * SuSE 9.1 with gcc 3.3.1
