Now that I have a lot of free time, I set up a blog to talk about my GSoC project (Development of a hardware-accelerated VP8 video decoder) and its progress. Stéphane Marchesin suggest a while ago that all students register there blog to planet.freedesktop.org so there is it !
The blog can be found here : https://emericdev.wordpress.com/
I've added your blog now.
Ok thanks !
