Another cool effort was by Philippe Normand from Igalia who put a lot of effort into porting WebKit to use 0.11. His efforts where rewarded with success as you can see in this screenshot.

Jonathan Matthew had flown up all the way from Australia and made great progress in porting Rhythmbox over to the 0.11 API, a port which became hugely more useful after Wim Taymans and Tim-Phillip Muller fixed a bug that caused mp3 playback not to work .

Peteris Krisjanis made huge strides in porting Jokosher to 0.11. Although like Jason DeRose from Novacut and myself on Transmageddon he did end up spending a lot of time on debugging issues related to gobject-introspection. The challenge for non-C applications like Jokosher, Novacut, Transmageddon and PiTiVi is a combination of the API having changed quite significantly due to the switch to gobject-introspection generated bindings, some general immaturity challenges with the gobject-introspection library and finally missing or wrong annotations in the GStreamer codebase. So once all these issues are sorted things should look a lot brighter for language bindings, but as we discovered there is a lot of heavy lifting to get there. For instance I thought I had Transmageddon running quite smoothly before I suddenly triggered this gobject-introspection bug.

There was a lot of activity around PiTiVi too, with Jean-François Fortin Tam, Thibault Saunier and Antigoni Papantoni working hard on porting PiTiVi to 0.11 and the GStreamer Editing Services library. And knowing Jean-François Fortin I am sure there will soon be a blog with a lot more details about that .

Thomas Vander Stichele, who also wrote a nice blog entry about the event, was working with Andoni Morales Alastruey, both from Flumotion, on porting Flumotion to 0.11, but due to some of the plugins needed not having been ported yet most of their effort ended up being on porting the needed plugins in GStreamer and not so much application porting, but for those of you using plugins such as multifdsink, this effort will be of great value and Andoni also got started on porting some of the non-linux plugins, like the directsoundsink for Windows.

Josep Torra from Fluendo ended up working with Edward Hervey on hammering out the design for the clutter-gst sink at the conference, but he also found some time to do a port of his nice little tuner tool as you can see from the screenshot below.

Tuner tool for GStreamer 0.11

George Kiagiadakis kept hammering away at the qtGStreamer bindings, working both on a new release of the bindings for the GStreamer 0.10 series, but also some preparatory work for 0.11.

In addition to the application work, Wim Taymans, Tim-Phillip Müller and Sebastian Dröge from Collabora did a lot of core GStreamer clean ups and improvements in addition to providing a lot of assistance, bugfixing and advice for the people doing application porting. All critical items are now sorted in 0.11 although there are some nice to have’s still on the radar, and Wim plans on putting out some new releases next week, to kickstart the countdown to the first 1.0 release.

As for my own little pet project Transmageddon, it is quite far along now, with both manually configured re-encodes and profile re-encodes working. Still debugging remuxing though and I am also waiting for the deinterlacer to get ported to re-enable deinterlacing in the new version. For a screenshot take a look at the one I posted in my previous blogpost.

GStreamer Hackfest Malaga 2012

Also making good progress on Transmageddon, even if the move to GObject Introspection bindings are making things a bit more complicated. Screenshot below of the progress so far.

Also a big thanks to Fluendo who is sponsoring the lunches at the hackfest and Collabora who is sponsoring tonight’s dinner. Ensuring that no hacker is left hungry during this hackfest.

Update: Yaiza took these photos from the hackfest

Also want to say a special thanks to the community members attending the event on their own and also to the companies sending their employees to the hackfest; Collabora, Fluendo, Flumotion and Igalia and finally a special thanks to the GNOME Foundation for sponsoring some of the attendees.

Hopefully I will be able to post some screenshots of a fully functional GStreamer 1.0 Transmageddon next weekend

Transmageddon running GTK3 and GStreamer 0.11/1.0

Hopefully it is a sign that the upcoming GStreamer hackfest in Malaga will be a great successful everyone who is participating.

I hope the remainder of the porting effort will be relatively simple as I would love to get back to working on real features instead of just updating old functionality to use a new backend to do the same. Having had a need for Transmageddon for a couple of work related tasks recently a couple of items, like batch job programming has moved up my priorities list.

We will be offering some travel sponsorship, so even if you are short on cash we hope to have you attend, more details on the hackfest&codesprint wiki page.

For those wondering why we choose Malaga, well the reason is that Wim Taymans, the GStreamer 1.0 designer and lead developer lives there, and at a previous hackfest we tried to do in Oslo he ended up in Helsinki instead. So this time we are taking no risks, but instead we are taking the hackfest to him

The demo, while simple, is quite cool, showing off our HTML5 based touch screen interface all built on top of Webkit and the GStreamer Editing Services. The embedded video is to be found on the GStreamer Editing Services page.

As a sidenote, to make this I actually relied on the GNOME 3 built in screen capture support, which I have to say worked like a charm Always felt screen casting to be a pain before, but this time it worked very well for me.

This time we are talking with Youness Alaoui who is one of the maintainers of Farstream, the audio and video conferencing framework built on top of GStreamer. We also cover another of Youness Alaoui projects, libnice, the NAT traversal library. So if you want to know what is happening with audio and video conferencing on Linux be sure to read the full interview with Youness Alaoui here.
