This mail announces the release of Flumotion 0.5.2 'Can Tomas'.
Flumotion is a GPL streaming media server written in Python. It is distributed
and component-based: every step in the streaming process (production,
conversion, consumption) can be run inside a separate process on separate
machines.
Flumotion uses Twisted and GStreamer. Twisted enables the high-level
functionality, distributing components over the network. GStreamer, through the
Python bindings, enables the high-speed low-level functionality: actual media
processing.
Flumotion uses a central manager process to control the complete network; one
or more worker processes distributed over machines to run actual streaming
components; and one or more admin clients connecting to the manager to control
it.

Release notes for Flumotion 0.5.2 "Can Tomas"
The Flumotion team proudly announces
a new release of the development 0.5 branch
of the Flumotion Streaming Server.
Flumotion is a streaming media server created with the backing of
Fluendo. It features intuitive graphical administration tools, making
the task of setting up and manipulating audio and video streams easy for
even novice system administrators. Flumotion is released under the GPL.
Overview
After the winter release that was bursting with features and changes,
it was time to shift the development focus more towards stabilizing our
software and improving the user experience.
The wizard has been completely re-written to modestly just work and
not get in your way. The GTK+ admin interface has received a number of
improvements. One new component has been added and we didn't forget
about the existing ones, either.
Below is a summary of user-visible features. A full list of all closed
tickets can be found at the end of this announcement. Existing
Flumotion users are strongly encouraged to upgrade and report on your
experiences. If you haven't yet tried Flumotion, now is a great time
to start!
Features of this release
* The wizard has been re-written completely.
Forward, back, and random access navigation through the wizard
pages should now work better. There is now an option to
automatically serve Cortado in a web page. A shoutcast
consumer has been added. The wizard queries the manager for
capabilities, allowing add-on projects to plug in different
components and wizard pages into the wizard for producers,
encoders and consumers.
* The GTK+ admin now offers a new tab in the component view
providing information about the component's process (uptime,
CPU usage, virtual memory size, etc.); tooltips have been
added to a number of UI elements and also the status bar
provides more information.
* A debug option has been created that hides the scary debug
parts for the average user, but at the same time allows more
debugging power for the less easily scared users. It now
allows setting log levels for GStreamer and Flumotion on the
fly per component.
* New Dirac encoding component (also supported directly in the
wizard)!
* The HTTP server component can limit the bitrate at which it
serves files and can also be easily set-up to serve Cortado
applets with the supporting HTML and JavaScript files.
* The FireWire producer allows selecting devices by GUID - now
it's possible to specify one of the connected devices, or even
use multiple devices if they are connected to different buses.
Known issues
* The set of switch components don't currently work due to an
issue with the underlying input-selector GStreamer element.
* The overlay and composite components may generate many gst
CRITICAL log messages with the recent versions of GStreamer -
it is superficial and shouldn't affect their work.
