While you can follow the progress of Rygel through the release announcements on my blog, mailing-lists and even git log, I feel that I am not providing enough information about the future plans. Also there are some things that are not (or so far have not been) in a shape to be part of a release so here is some of what is coming:

- Fix some (potential) crashes.
- Make database operations cancellable.

latin1 range.

Introducing Zhaan

I mentioned this cool guy Zachary Goldberg in my blog and in my talk before. While I mentioned his name in regards to his efforts to making sure GUPnP glues nicely with gobject-introspection and is usable from Python, he went much further than I expected and made a cool new UPnP control-point for N900 based on GUPnP in Python. He named it Zhaan (another character from Farscape in the spirit of Rygel).

Some mandatory screenshots:




You can check out more screenshots/specs of the project and follow its status here.

There are many people out there making cool UIs but they end-up using wrong tools and/or re-inventing the wheel so its nice to see someone doing cool stuff but the right way. :)

We can has Python too

Zachary Goldberg reports:

As I've been mentioning lately I have been working on using PyGObject + GObject Introspection (recently forked, now called PyGI + PyGObject + Gobject Introspection) and have some exciting news!

I have been working on fleshing out a whole bunch of unit tests which exercise the entire GUPnP API. I hate a major roadblock in that PyGI did not support native callbacks! So, after a week or two detour I have implemented PyGI callbacks (which now work rather nicely, but need a bunch of stylistic cleanups and error checking before its pushed back upstream.. priorities!) as well as some working GUPnP demos.

My best demo so far is about 25 lines of python which:

1) Gets all devices on one network interface
2) Scans for all the services each device provides
3) If the device is GMediaRenderer and it provides an AVTransport Service (it does...) then it
3a) Stops whatever is currently playing
3b) Loads a new URI (hardcoded from my mediatomb server for now, havn't played enough with gupnp-av to dynamically get the mediatomb data -- for now!)
3c) Initiates playing

3a->3c have been tested using the synchronous GUPnP action api (send_action...) as well as the asynchronous API (begin_action.... end_action...) with callbacks!

Update: Seems this info is out-dated already, Zach has done quite some more after this.
