Returns a OptionGroup 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 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).
