QtGStreamer is a bad choice for that, as it is mostly outdated. I recommend
using out-of-the-box Qt (VideoOutput, QAbstractVideoSurface) as much as
possible. Maybe you can pull the videosink implementation from QtGStreamer and
use that. Meanwhile, I will check with my boss whether we can publish the Qt
videosink we have.
