Hi,

The compiler I'm using is g++ 5.2.1.

    gst_structure_new("foo", NULL)
will cause compile-time warning: not enough variable arguments to fit a
sentinel [-Wformat=]


Using
    gst_structure_new("foo", NULL, NULL)
instead can dismiss the warning.

In this tutorial
http://docs.gstreamer.com/display/GstSDK/Basic+tutorial+5%3A+GUI+toolkit+integration
gst_structure_new need only one NULL to terminate its argument list.

The tutorial is for GStreamer 0.1, obviously.

Just wondering if this double-NULL needed is an intentional change in GStreamer
1.0 or a bug?

Thnaks :)
