GUADEC 2015

At the beginning of this month I've spent a few great days in Goteborg, at GUADEC conference. That was my second GUADEC (first time I've participated last year, in Strasbourg).

There were a lot of interesting presentations, but the most I enjoyed all of the keynotes. As a Google Summer of Code student (I've worked for GStreamer project [1]), I was able to give a lightning talk about my project. It seemed to be interested to some people, so after that someone asked me to show him my project "in action". We were talking about possible improvements and new features.

In the evenings organizers prepared for attendees some event, so I could integrate with other GNOME people. Moreover, they organized for us (GSOC students and mentors) a dinner, so I could meet other students a little bit better, talk mostly about our summer projects, but also about differences in education at their universities  (people came from different part of world).

In conclusion, I enjoyed GUADEC, all presentations and evening events. I'd like to thank the GNOME Foundation for sponsoring my travel and my hostel. My participation probably wasn't be able without Foundation's help. Thanks a lot!

GStreamer Debugger - introduction

Hi everyone,
This year I've been accepted to Google Summer of Code :) Last year I worked on Banshee project [1], and this year I joined to GStreamer [2] team.
This summer I work on tool for GStreamer-based applications - GStreamer Debugger.

Goals
At the end of this summer, I'm going to provide you an application, which allows you to connect to your remote pipeline (obviously, lo interface can be used as well :)), watch pipeline graph (and its changes), spy selected queries, events, log messages, messages from bus and log messages, and even buffers. Application won't allow user modify pipeline and pipeline's state, but who knows - if it is useful feature, I implement it in the future.
GStreamer doesn't provide possibility to connect to pipeline, so I have to do it on my own.

Progress
June is a month, when I've exams on my university (fortunately, I've already passed all of them!), so I didn't spend as much time as I wanted on this project. Anyway, I accomplished a few milestones.
There's a list, what already has been done:

• gst-trace [3] plugin, containing tcp server. For now, it sends GstEvents, GstMessages, and log messages to clients (todo: send GstBuffers, and GstQueries)
• client application, which displays events and log messages (todo: display GstBuffers, GstQueries, GstMessages). I have a lot of ideas, how to improve client application, but I'm not sure whether I meet GSOC deadline, so I suppose, most of them will be implement after Google's program. 
• protocol - I used Google Protobuf library [4]. In general, I've defined most of protocol's structures, I just make minor improvements, when I need it.

Below you can find a few screenshoots of client application. Full code can be found on my github account ([5], [6]).
