This page summarize the current list of ideas for VideoLAN project, for [https://summerofcode.withgoogle.com Google Summer Of Code 2017]. The list is not exhaustive, and is not limitative. Feel free to apply with your own idea!

== Introduction &amp; Information  ==

This wiki page covers the attempt by the [[VideoLAN]] project to act as a mentoring organization for [http://code.google.com/soc/ Google Summer of Code], in order to improve {{VLC}} and [[VLMC]]. 

[[VideoLAN]] was a mentoring organization in [[SoC 2007|2007]], [[SoC 2008|2008]], [[SoC 2009|2009]], [[SoC 2010|2010]], [[SoC 2011|2011]], [[SoC 2013|2013]] and [[SoC 2016|2016]]. 

This page list the ideas for VLC and VLMC.

=== VLC media player  ===

{{VLC}} is a cross-platform multimedia player, encoder and streamer application. It is one of the most successful open-source projects without any professional structure underneath. 

{{VLC}} is downloaded at an approximate monthly rate of 40 millions from the main website and that's not including third-party distributions (Linux)! 

You can find more information on [http://en.wikipedia.org/wiki/VLC_media_player VLC on Wikipedia] or on this [[Main Page|wiki]].

=== VideoLAN Movie Creator ===
[[VLMC]] is a cross-platform non-linear video editing software based on VLC technology. It was started as a final year student project at the French IT school [http://www.epitech.eu EPITECH].

[[VLMC]] currently awaits a transition to the current libvlc API and it's actual 1.0 release!

=== Summer of Code  ===

If selected and developed, SoC projects for VLC and VLMC will be included in later releases.

All projects are covered by the GPL (v2+) or LGPL (v2.1+) licenses depending on the module.

=== Compile VLC or VLMC ===
This may sound trivial, but it's harder than many expect. See https://wiki.videolan.org/Category:Building/ for more informations.

=== Provide a small patch ===
To demonstrate your skills, share a small patch with us. This will let you become familiar with [[Git]], in case you don't know it already and our process on [[Sending Patches VLC|merging patches]].

=== Let's get in touch ===
We have 3 major communication channels: Our [https://mailman.videolan.org/mailman/listinfo mailing-lists] to discuss patches and further development related topics. Furthermore, we have our [http://forum.videolan.org web forums] for VLC-related end-user support - a VLMC section will be created once the product is published. Finally, there is our IRC channel ''#videolan'' (for VLC) and ''#vlmc'' on the ''Freenode'' network. It's open to any kind of discussion. Usage issues, questions how to compile VLC/VLMC, getting to know the fellow developers, etc.

== Key ideas for VLC ==

=== Fuzz VLC (and maybe LibVLC and VLC ports) with LibFuzzer ===

libFuzzer ((http://llvm.org/docs/LibFuzzer.html).) is a library for coverage-guided fuzz testing.

* The first step of this GSoC project is to implement Fuzz Targets (http://llvm.org/docs/LibFuzzer.html#fuzz-target) to test various parts of the VLC project. The non exhaustive parts will be the following VLC modules API: "decoder", "encoder, "access", "packetizer", "demuxer". For each parts, the student will have to understand the module API in order to effectively implement the target.

* The second step is to find valid corpus (http://llvm.org/docs/LibFuzzer.html#corpus) for every module types and for every modules (mkv input for mkv demuxer, mp4 input for mp4 demuxer, h264 input for h264 decoder...).

* The third step is to host and run the fuzzer. It's not decided yet if the fuzzer will be hosted by google (https://github.com/google/oss-fuzz) or by the VideoLan association.

* If there is enough time, the fourth and final step is to fix the issues that has emerged during the previous steps
