If the Video node is in the scene, but the hiarchy includes a node from a ComponentLibrary, the roSystemLog does not fire events.
Example:
<Scene>
<Group>
<!-- MyComponent is loaded from a ComponentLibrary -->
<MyComponent>
<Video />
</MyComponent>
</Group>
</Scene>
If the Video node or ANY of its parents are defined in a ComponentLibrary, then roSystemLog does not log events.
To be clear, roSystemLog is used normally in the main task of the app.
