Hi there,
we are happy to announce our next major release:
NMM 0.9.0 "Yellow"

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, is implemented in C++, and 
distributed under the LGPL. For more information, see: 

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 
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 

NEW in this release are:
* Multimedia box:
    - The TV state supports multiple TV sources. According to the 
preferences of the user, the TV state switches between available TV 
sources automatically.
    - Improved transcoding state which allows for distributed 
transcoding of arbitrary audio/video files.
    - Added state which allows to control a distributed camera via 
remote control
    - Many minor extensions and bug fixes
* 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 ImageMagick library to latest version 6.2.2
    - Updated libdvdread library to latest version 0.9.4
    - Updated mpeg2dec library to latest version 0.4.0b
    - Updated ffmpeg library to latest version 0.4.9pre1
* Added AlsaPlaybackNode which uses the Alsa interface for audio 
playback (implemented by Andrés Otón)
* Many bugfixes in plug-ins and NMM base
* Updated documentation (see 
http://www.networkmultimedia.org/NMM/Docs/index.html )
* Updated installation instructions (see 
http://www.networkmultimedia.org/NMM/Download/index.html )

Together, the 0.9.0 release consists of several parts:
(1) The NMM-base system
(2) Over 60 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
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: 

(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 or 
from a given URL.  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 sarge with gcc 2.95.4
* Debian sarge with gcc 3.3.5
* SuSE 9.1 with gcc 3.3.3
* SuSE 9.3 with gcc 3.3.5
* Red Hat 9.0 with gcc 3.2.2
