After a while, I finally released a new version of VLC-Qt. This version is mainly a bugfix release but also features some important changes.
The library has been separated into core and widgets part, because if used in QML, we do not need a dependency on QtWidgets module. Video widget has also been reworked a little bit.
VLC-Qt now supports both Qt4 and Qt5. I currently provide MSVC 2010 builds for Windows for both Qt versions, Ubuntu packages and Arch AUR. You can download VLC-Qt from new SourceForge mirror or wait for all packages to be updated.
