<p><b>GStreamer and OMAP4, Rob Clark, Texas Instruments</b></p>
<p>Rob Clark has been working in the arm embedded world for more than 10 years, and
playing with linux for even longer. And most recently, gets to combine the
two. For the last year or so, he has been making GStreamer work with the
hardware accelerated codecs and video on the TI OMAP4 platform.
</p>
<p>
An overview of GStreamer based multimedia on TI OMAP4 linux platform. For
optimal integration of the accelerated video encoders and decoders, camera,
and display we ran in to a number of missing features in GStreamer, such as
support for rowstride, more flexible caps negotiation, zero copy crop/vstab,
buffer padding and alignment requirements. In addition, there is still
optimization possible if cache operations (invalidate/clean) could be
eliminated in pipelines where we know software is not touching the buffers,
as would typically be the case on an SoC like OMAP4. We would like to
present how we've solved these problems currently, and how we could possibly
solve them in GStreamer 1.0.</p>

<p><b>Implementing DLNA using GStreamer, Zeeshan Ali, Nokia</b></p>
<p>Zeeshan Ali is a Lead Developer/Architect at Nokia MeeGo Computers division in Helsinki, He started as a GStreamer
plugin and application developer and is known in the GNOME community for his video-whale project.
For the past three years, he had been obsessed with UPnP and in turn the GUPnP project and Rygel.
When he gets some time from his office work and GUPnP, he hangs around with his wife, plays Star Trek Online &
Street Fighter in his spare time and sometimes tries to learn some Finnish.</p>
<p>Rygel is a collection of DLNA (UPnP AV) services implementing the <a href="http://www.dlna.org">DLNA</a> standard for
interoperable multimedia devices, implemented through a plug-in mechanism. UPnP in simplest words is a set of protocols
that defines how different devices on a home network can seamlessly (without or with minimum configuration) communicate with
each other. This talk will introduce you to the current state of Rygel and give you an introduction how Rygel can be quickly
deployed to enable you to ship a DLNA-enabled device.

<p><b>Integrating VideoConferencing into Everyday Applications, Olivier Crete, Collabora</b></p>
<p>
Olivier Crete has been involved in free software since 2000. He's been the
maintainer of GnomeICU (a Gnome ICQ client) since 2002 and a Gentoo
developer since 2003, starting the amd64 port and also helping maintain
various IM applications. He currently works for Collabora on GStreamer,
the Farstream VoIP framework and its integration into Telepathy.
</p>
<p>
This talk will discuss how until now, videoconferencing has lived in dedicated applications.
We've had instant messengers with VoIP, softphones, but they don't integrate
into the everyday workflow. Farstream, the next generation of Farsight,
the GStreamer based VoIP and videoconferencing framework not only
provides media handling to communication applications such as Empathy,
Pidgin, aMSN and the Nokia Internet Tablets, but can also be used to
integrate videoconferencing into everyday applications.</p>
<p>This talk will give a brief introduction to Farstream and Telepathy and how they
integrate. I will then show how to integrate videoconferencing features
into an application such as a non-linear editor. It will also demonstrate
how easy it is for application developers to integrate such features
into their applications and how useful it can be for users.

<p><b>Optimizing multimedia with Orc, David Schleef, Entropy Wave.</b></p>
<p>David Schleef is one of the leading experts on open source multimedia. He has been active for
13+ years in leading and developing several open source projects, including GStreamer, Swfdec, Comedi,
Dirac/Schroedinger, and Liboil/Orc. His most recent project, Orc, allows developers to harness the
power of CPU vector extensions without having to write assembly code or intrinsics. Allegedly, he got
tired of writing yet another thousand lines of assembly code and wrote a program to write it for him.
</p>
<p>
This talk will present the Orc library and set of tools for compiling and executing very simple programs that operate on arrays of data.
The “language” is a generic assembly language that represents many of the features available in SIMD architectures, including
saturated addition and subtraction, and many arithmetic operations. The talk will also cover the recently released
NEON backend for ORC.</p>

<p><b>SLTV - live streaming for the masses, Luciana Fujii, Holoscopio</b></p>
<p>
<a href="http://sltv.holoscopio.com">SLTV</a> is a free software designed to allow
live recording and streaming with a simple GTK+-based interface.
Features include switching sources, picture-in-picture, watermark,
multiple filters and multiple simultaneous outputs without stopping the
pipeline.
</p>
<p>
The main challenge during SLTV development was to dynamically change the
pipeline to, for instance, change which video effect to apply on the
fly. Although most of the software features may seem simple if
considered separately, the resulting pipeline became quite complex, and
the same was true for making all the pieces fit together.

<p><b>Using ICE middleware with GStreamer to implement real-time
QoS-aware video streaming for remotely controlled vehicle.
, Andrey Nechypurenko and Maksym Parkachov</b></p>
<p>Andrey Nechypurenko is currently working as a senior software engineer
at General Electric. He has many years of experience in defining
architecture and implementing large scale distributed real-time and
embedded systems in automotive and industrial automation domain. As
his hobby, Andrey is developing different kinds of ground and air
vehicles which can be controlled over the Internet.</p>
<p>
Maksym Parkachov is working as senior CRM consultant at the Riverland
GmbH. His expertise area lies in integration of the enterprise
front-facing applications with industry standard back-ends,
optimizations of parallel processing systems and data quality
processes implementation . In his free time, he is building remote
controlled embedded systems.</p>
<p>
Typically, remotely controlled vehicles are equipped with video camera
to let the remote driver see surrounding environment. To enable
precise control of the vehicle over the Internet, it is necessary to
assure low video latency and ability to adapt to the changing network
conditions. In addition, low power consumption is required to increase
the battery-based operation time. In this paper we: a) outline our
embedded control system based on BeagleBoard open hardware and
Ångström Linux distribution; b) provide requirements, motivation and
describe how we build real-time quality of service (QoS) aware video
streaming solution with ICE open-source middleware and GStreamer on
this platform; c) we contrast and compare our solution with
RTP/RTCP-based streaming alternatives and d) provide performance
measurements for our adaptation algorithms.

<p><b>3D Stereoscopic and GStreamer, Martin Bisson</b></p>
<p>
Martin Bisson has completed his Master's Degree in Computer Science at École Polytechnique de Montréal, working on a 3D visualization
tool for minimally invasive spine surgery. During his studies, he worked for various high technology companies in the fields of
image and video processing as well as computer graphics, such as Matrox and Autodesk (Media & Entertainment Division formerly
known as Discreet). In 2008, he co-founded Float4 Interactive (www.float4.com), a creative technology company that develops interactive
systems for entertainment, advertising and design applications.
</p>
<p>With recent developments in 3D video technology and its success, adding support now for this uprising technology will make
GStreamer an attractive choice for application developers. The support has been implemented as part of a Google Summer of Code
project. Different possible implementations, each with its own strengths and weaknesses, were considered, but a simple and
hopefully complete one was chosen. ORC can be used for the CPU-intensive but easily parallelized task of generating anaglyph images.
Work still needs to be done, especially on support of different 3D display hardware..</p>
