<br>
The pipeline is correct, but you have to understand the actual code<br>
there. Tutorial 5 uses playbin, which implements the GstVideoOverlay<br>
interface. And that is used by Tutorial 5 to tell playbin where to<br>
render the video.<br>
<br>
A generic pipeline like yours does not implement GstVideoOverlay, so<br>
Tutorial 5 just fails. You have to change the code so that it uses the<br>
GstVideoOverlay interface of the video sink directly, see the<br>
documentation how to do that.<br>
