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

Introduction & Information

This wiki page covers the attempt by the VideoLAN project to act as a mentoring organization for Google Summer of Code, in order to improve VLMC and VLC media player.

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

This page list the ideas for VLMC and VLC.

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 EPITECH.

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

libVLC

VLC media player 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 media player is downloaded at an approximate monthly rate of 23 millions from the main website and that's not including third-party distributions (Linux)!

You can find more information on VLC on Wikipedia or on this wiki.

The engine of VLC is libVLC, and is used by VLMC.

Summer of Code

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

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

Compile libVLC 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 merging patches.

Let's get in touch

We have 3 major communication channels: Our mailing-lists to discuss patches and further development related topics. Furthermore, we have our 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 libVLC) 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 VLMC

Port to Android

VLMC is now working on the desktop. It would be nice to port it also to the mobile world, starting by Android.

This project would require to adapt to smaller screens, and simplify the UI to fit the Android workflow.

This project requires C++/Qt/qml knowledge, and access to Android devices.

Proposed mentors: Geoffrey/Hugo

Workflow rework

VLMC is now working on the desktop, but it is quite slow and missing some use cases.

This should be fixed in MLT framework backend for libVLC. See the work from the previous Summer of Code.

Proposed mentors: Hugo

Workflow audio filters

VLMC is now working on the desktop, but it is missing several audio and video filters.

This project would add audio filters on the MLT framework backend using the LADSPA library or a similar open source library.

Proposed mentors: J-B

Workflow video filters

VLMC is now working on the desktop, but it is missing several audio and video filters.

This project would add video filters on the MLT framework backend using the lv2 library or a similar open source library.

Proposed mentors: Felix

Key ideas for libVLC

Fuzz libVLC 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 libVLC project. The non exhaustive parts will be the following libVLC 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.

This project requires C and C++ knowledge.

libVLC AirPlay support

libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the Airplay protocol, for Apple devices.

We want to be able to do that from any device, including Android or Windows machines.

This will use the new renderer APIs added in libVLC 3.0.

This project requires C knowledge.

Proposed mentor: tguillem

libVLC UPnP renderer support

libVLC is now able to send video to the ChromeCast devices. We want to be able to do the same using the UPnP Renderer protocol, for all the connected TV devices that support this protocol.

We want to be able to do that from any device, including Android, iOS or Windows machines.

This will use the new renderer APIs added in libVLC 3.0.

This project requires C knowledge.

Proposed mentor: tguillem

VLC web interface modern look

The Web interface of VLC is a very ugly player and we want to improve that quite a bit.

This can be done in React, RxJS or Vue.JS to achieve a modern look, with transparency and cross-platform support.

This project requires JavaScript knowledge and experience. The choice of the Framework can be changed if needed.

Proposed mentor: David Loiret

libVLC 3D video support

libVLC is able to play most 2D and Side-By-Side videos, but the support of 3D is very limited.

Because of 360 and VR support, the attention about 3D is getting very popular those days. We need to support that in libVLC.

This project requires C knowledge.

Proposed mentor: tguillem

libVLC VR support

libVLC is able to play most 2D and 360 videos, but the support of VR is very limited.

Because of 360 and VR support, the attention about VR is getting very popular those days. We need to support that in libVLC.

This project is mostly connecting a new headset to libVLC to get support in all libVLC applications.

This project requires C knowledge.

Proposed mentor: tguillem

VLC macOS interface rework

The VLC interface is quite outdated on macOS.

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

This project requires Obj-C knowledge.

Proposed mentor: David F

VLC Qt interface rework

The VLC interface is quite outdated on Linux and Windows

This project for the summer is to rework heavily this interface to make it beautiful and useful again.

This project requires Qt/C++ knowledge.

Proposed mentor: J-B
