[vlc-devel] [PATCH 4/4] qt: medialib: remove QObject from MLVideo

[Romain Vimont]

MLVideo instances are created from a QThreadPool thread. As a
consequence, as a QObject, each one live (by default) in this separate
thread.

The behavior of dynamic properties or signals/slots would be confusing,
so do not inherit QObject.
