Hi there,
we are happy to announce our next release:
NMM 0.9.1 "Packetized"

The Network-Integrated Multimedia Middleware (NMM) provides an
architecture that allows to create distributed multimedia applications
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

*Download* : http://www.networkmultimedia.org/Download/index.html

*New*: From this release, we will provide packages for different
distributions to simplify the installation process of NMM. Right now, we
provide packages for the following distributions:
      - Debian Sarge
      - RPM packages for SuSE Linux 9.3
      - RPM packages for Fedora Core
      - RPM packages for RedHat Linux 9.0    
http://www.networkmultimedia.org/NMM/Download/Package/index.html for a
detailed description.

*New*: We updated the second Beta version of NMM-Oppix, a Live-CD based
on Knoppix Version 3.7, to the latest NMM version 0.9.1. NMM is fully
configured, so that all applications like our Multimedia-Box can be
started without additional configuration steps.
For more information see:
*NEW* in this release are:
    * Multimedia box:
      - many minor extensions and bug fixes
    * Updated plug-ins:
      - Added NMM version for Shoutcast library
    * Many bugfixes in plug-ins and NMM base. Thanks to all contributors!
    * Updated documentation (see
http://www.networkmultimedia.org/NMM/Docs/index.html )
    * Updated installation instructions (see
http://www.networkmultimedia.org/NMM/Download/index.html )
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 playback 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

  * The graph builder allows to automatically create a distributed flow
graph from a given URL. All required plug-ins for media playback, such
as audio or video decoder, are automatically detected. In general, all
file formats and codecs supported by NMM are also available when using
the graph builder. See
http://www.networkmultimedia.org/current/Docs/clic/x142.html for a
complete list of supported URLs.

Together, the 0.9.1 release consists of following 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 plug-ins

(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
    - 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. 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

If you would like to get involved in the development of NMM, or you want
to develop an application on top of NMM, or you simply want to ask a
question or report a bug, you are welcome to subscribe to our developer
mailing list [nmm-dev] at:
