Instead of always using xvimagesink as GStreamer backend for the widget and window control (works only with X11), we now try to pick a video sink that fits the current configuration. It first tries a set of known video sinks that can work with the Qt platform plugin in use. If none is available, it dynamically picks a video sink available on the system that can be used with our backend. Even if the video sink is now picked in a smarter way, xcb is still the only supported platform plugin. The reason is that it's the only Unix plugin which can provide a valid native window handle. Additional work is needed to support other plugins like wayland or directfb. Change-Id: I3843dea363d6a0b85a6cc1f2952783b743e48ac6 Reviewed-by: Christian Stromme <christian.stromme@theqtcompany.com>
