The War Against Deadlocks, part 1: The story of our new thread-safe mixing elements implementation

Let me tell you of a story that was lost and forgotten amidst Pitivi’s development battlegrounds last fall, a manuscript that I recovered from a Moldy Tome in a stony field. According to my historical data, the original author was a certain “Dorian Leger”, a French messenger that went missing from the vicinity of Paris.

Retour de GUADEC, conspirations

As expected, GUADEC in Strasbourg was a terrific event. Huge props to the local organizing team who managed to make things work regardless of last minute curve balls, such as the venue changing or the video recording team (and their equipment) not being able to attend due to visa restrictions.

GSoC 2014 projects for Pitivi: transformation, chroma keying, image sequences

Thanks to GNOME, we will be able to get some reinforcements for Pitivi this summer.

We’re very pleased to have Lubosz Sarnecki making a comeback! In 2011 he implemented the cairo-based clip transformation (zoom/resize/crop) feature in the viewer. Lubosz is quite experienced with OpenGL, Blender and GStreamer, as you can see on his blog  and the variety of projects he contributes to.

How do you visually represent a project’s timeline?

Here is a fun example to illustrate why software development in general is a complex endeavour:

  1. You think you’re going to fix a tiny problem: “hey, maybe we could make ‘s welcome dialog look a bit nicer“.
  2. Eventually, someone proposes a design or idea that looks interesting, and you realize that to truly realize it, you should also implement an audacious new feature: a way to visually represent an entire timeline as a thumbnail (that one is an open question, by the way; if you have some clever ideas, feel free to share them)
  3. …and to display new feature B properly, you should also consider—ideally—being a good citizen and implementing feature C upstream, in the toolkit you use instead of doing your own thing in your corner.
