Google Summer of Code

From Pitivi wiki
Jump to: navigation, search

The Google "Summer of Code" program is available for students only. If we accept your project proposal, in June-July-August you work on your project while being payed by Google. Mid-term and end-term we evaluate your work.

On the technical side, it might interest you that we use GES/GStreamer as backend, GTK for the UI, the Meson build system, and Flatpak to make builds for users. Flatpak also allows us to have a sandboxed development which means it's very easy to setup, you are set up in no time, and you don't have to run a virtual machine or f**k up your system to be able to build the latest GStreamer and Pitivi. See the section at the top of the contributing page for details why Pitivi is important.

While a GSoC with us is one of the most fun and rewarding experiences you can get, you need to consider it as professional work:

  • GSoC projects are on a "full-time" basis, not "part-time". What this means is that you should not apply if you have some strange schedule where, for example, you have school exams for many weeks between early May and late August. If you have school exams/obligations during the summer, you need to mention them and account for them in your schedule.
  • No excuses! We expect you to be a reliable, hard-working person. If things don't go well because for example your roommates are noisy, you don't have air conditioning, or your internet connection is unreliable, and you can't fix it, tell us so we can terminate your GSoC.

Since 2014, our official policy is to ignore "theoretical" applications — to be eligible, you must have gotten involved early-on and made at least one contribution prior to applying. Read more about our stance in this blog post: "Applying for a GSoC project is all about early involvement and commitment". If you are interested, the best thing you can do is to come to our IRC channel now, to make sure we have enough time to get to know you.


Who we are looking for

We are looking for smart and talented developers interested in multimedia and video editing.

You need to be highly communicative. Stuck on a problem? We need to know. Achieved a milestone or solved a really nasty problem? The entire world needs to know. We require to see you in our IRC channel, that's where you can meet the team, where you follow what's going on and that's where we'll communicate. Email is not sufficient. If you're new to IRC, check out IRCCloud.

You must have experience with Python or C, depending on your project. Knowledge of Git, GStreamer and related technologies is a plus. Familiarity with Test-Driven Development is a plus.

What we offer

You have a fantastic learning opportunity to play with technologies such as GStreamer, GTK+, Python, etc. We'll direct you to make great use of the tight-knit GStreamer and GTK communities so you have high-quality feedback throughout your project.

You can improve the lives of thousands of users by working on a tangible and fun project.

You have the opportunity to present your accomplishments to others at GUADEC where you can also meet with us. In past years the travel expenses for GSoC students have been covered by GNOME.

How to apply and get started

You don't have to be a veteran hacker but it is important that you prove to us — and to yourself — that you know what you're getting into and that you can handle it. You need to demonstrate that you have sufficient technical skills, motivation, and have some familiarity with the application and its source code. This also ensures that you get to know members of the community and have sufficient time and information to properly plan your project.

See also our official stance (as of 2014) on the matter and Lionel Dricot's blog post on "Being selected as a Summer of Code student".

Therefore, you should proceed like this:

  1. Come to our IRC channel and stick around.
  2. Setup your development environment and run the Test suite. Explore the development version of Pitivi, what works well and what doesn't, etc. See how you like it.
  3. To get a better idea of how comfortable you are with the code and community, make some small contributions to the code. Pick some small bugs to fix or pick a "small" task in the Pitivi tasks for newcomers list and have a go at it. Keep us in the loop. The earlier you start contributing, the more likely you know what you're getting into. Don't start contributing in March/April: we highly encourage you to start getting involved in January/February, or even earlier, to have time to try another team if we are not a good fit for you.
  4. Find a cool feature you need in Pitivi and tell us. Start making a design doc on how you plan to implement it.
  5. Fill out the application and apply officially to the Google's Summer of Code website under both the GNOME or GStreamer mentoring organizations, depending on your project.

Project ideas

Pitivi is a very modular video editor, whose architecture heavily depends on technologies like GES and GStreamer. The scope of your GSoC project will probably cover only Pitivi, but it could very well span multiple codebases:

  • Pitivi, which is the user interface. Written in Python. For those who love design and graphical user interaction.
  • GES, the high-level video editing GStreamer library that powers Pitivi and other applications. Written in C. For those who wish to improve an easy to use, powerful and flexible library for audio/video editing.
  • GStreamer, for low-level work, such as improving filters/effects, codecs, hardware decoding/encoding acceleration, analysis, etc. Written in C. For those seeking a challenging audio and video experience where optimization is key.

We'd love to see GSoC proposals originating from an itch you need to scratch. You are welcome to ask around and bring your own ideas. If you're not sure where you can be most useful, have a look at the "large" tasks in the Pitivi tasks for newcomers list. They are fun cool features very suitable for a GSoC project. See the roadmap for our overall vision for the project. Deadlines for applying are approaching fast, hurry up!
