Complete newbie to GStreamer here. I have installed GStreamer on Windows11 and have tried building and running the HelloWorld sample in the development tutorial, using VS Code. It compiles and builds OK, and I can step through the code with the debugger. In the code that creates the pipeline and its elements, only the pipeline object is a valid pointer - all the other create-element calls return a null pointer. What could I be missing here? Could it be because it cannot find some DLLs that it needs at runtime? I would have thought (hoped) that some sort of error message would appear if that was the case, but there are no errors appearing.
