* SECTION:gst
* @short_description: Media library supporting arbitrary formats and filter
* graphs.
- * @see_also: Check out both <ulink url="http://www.cse.ogi.edu/sysl/">OGI's
- * pipeline</ulink> and Microsoft's DirectShow for some background.
*
* GStreamer is a framework for constructing graphs of various filters
* (termed elements here) that will handle streaming media. Any discreet
* a powerful negotiation framework. Plugins are heavily used to provide for
* all elements, allowing one to construct plugins outside of the GST
* library, even released binary-only if license require (please don't).
- *
- * GStreamer borrows heavily from both the <ulink
- * url="http://www.cse.ogi.edu/sysl/">OGI media pipeline</ulink> and
- * Microsoft's DirectShow, hopefully taking the best of both and leaving the
- * cruft behind. Its interface is still very fluid and thus can be changed
- * to increase the sanity/noise ratio.
+ * GStreamer covers a wide range of use cases including: playback, recording,
+ * editing, serving streams, voice over ip and video calls.
*
* The <application>GStreamer</application> library should be initialized with
* gst_init() before it can be used. You should pass pointers to the main argc
* N_("Output tags (also known as metadata)"), NULL},
* {NULL}
* };
- * ctx = g_option_context_new ("gst-launch");
+ * // must initialise the threading system before using any other GLib funtion
+ * if (!g_thread_supported ())
+ * g_thread_init (NULL);
+ * ctx = g_option_context_new ("[ADDITIONAL ARGUMENTS]");
* g_option_context_add_main_entries (ctx, options, GETTEXT_PACKAGE);
* g_option_context_add_group (ctx, gst_init_get_option_group ());
* if (!g_option_context_parse (ctx, &argc, &argv, &err)) {
* by <application>GStreamer</application>. It is mostly used in unit tests
* to check for leaks.
