SoC 2016

This wiki page covers the work of the VLMC project as a mentoring organization for Google Summer of Code, in order to improve our VideoLAN Movie Creator (VLMC).

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!

Google Summer of Code Summer 2016

If selected and developed, GSoC projects for VLMC will be included in the initial release!

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

Getting started

Original good ideas will be valued. We don't want to impose anything. This is Free and Open Source software.

Compile VLMC

This may sound trivial, but it's harder than many expect. VLMC's compilation chain is different for every operating system. It doesn't really use the default toolchains on Windows or OS X, but a simple *nix like ./configure && make doesn't really do the trick either. We have plenty of information available on this wiki and we will happily provide help on our IRC channel.

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 end-user support. Finally, there is our IRC channel #vlmc on the Freenode network. It's open to any kind of discussion. Usage issues, questions how to compile VLMC, getting to know the fellow developers, etc.

Key ideas for VLMC

Implement a real Audio/Video sync

So far, the lip-syncing strategy used by VLMC is pretty much "hope it works".

As you would think, this quite often leads to desync, and thus makes VLMC unusable.

We need to come up with a real synchronization strategy, quite likely based on an abstract clock & PTS

Plug-in new libvlcpp & medialibrary

VLMC uses a from-sratch C++ binding to libvlc, which is stuck a few years in the past. Meanwhile, a new binding got written (https://code.videolan.org/videolan/libvlcpp/tree/master), and needs to be plugged in.

We also started working on a cross-platform media library, to replace the low-featured one, present in VLMC.

This media library will handle discovering media for the used, instead of having to manually importing every single file. This should also allow us to kill some of the "Backend" code, as a fair share of it is designed to create thumbnails. This is now done by the medialibrary, and can go away from the VLMC source code.

This probably requires a good C++ knowledge, as both libvlcpp & medialibrary make a heavy use of C++11 & templates meta-programming.
