Returns a GOptionGroup with GStreamer's argument specifications. The
group is set up to use standard GOption callbacks, so when using this
group in combination with GOption parsing methods, all argument parsing
and initialization is automated.
This function is useful if you want to integrate GStreamer with other
libraries that use GOption (see g_option_context_add_group() ).
If you use this function, you should make sure you initialise the GLib
threading system as one of the very first things in your program
(see the example at the beginning of this section).
