Tutorial 1 won't run

[imfatant]

Well, I finally got Tutorial 1 to compile in MSVC x64. However, only by
adding a static cast in the following line:

    // msg = gst_bus_timed_pop_filtered(bus, GST_CLOCK_TIME_NONE,
GST_MESSAGE_ERROR |    GST_MESSAGE_EOS);

to:

    msg = gst_bus_timed_pop_filtered (bus, GST_CLOCK_TIME_NONE,
static_cast<GstMessageType>(GST_MESSAGE_ERROR | GST_MESSAGE_EOS));

(I couldn't select any language standard earlier than C++11.)

When I execute the program, this is printed to the cmd window:

    (gstreamer.exe:444): GStreamer-CRITICAL **: 05:21:27.129:
gst_element_set_state: assertion 'GST_IS_ELEMENT (element)' failed

    C:\Users\Anthony\source\gstreamer\x64\Debug\gstreamer.exe (process 444)

    Press any key to close this window . . .

Please help. I _really_ want to get this working.
