Release notes for FlumotionĀ 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.

Release 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.
