And add strduped function pointer names to the global quark table, so that they don't get reported as lost by valgrind. This allows us to use GST_DEBUG when running tests under valgrind.

/**

* SECTION:gst
|
|
* @title: GStreamer
|
|
* @short_description: Media library supporting arbitrary formats and filter
|
|
* graphs.
|
|
*
|
|
* GStreamer is a framework for constructing graphs of various filters
|
|
* (termed elements here) that will handle streaming media. Any discrete
|
|
* (packetizable) media type is supported, with provisions for automatically
|
|
* determining source type. Formatting/framing information is provided with
|
|
* 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 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
|
|
* and argv variables so that GStreamer can process its own command line
|
|
* options, as shown in the following example.
|
|
*
|
|
* ## Initializing the gstreamer library
|
|
*
|
|
* |[ <!-- language="C" -->
|
|
* int
|
|
* main (int argc, char *argv[])
|
|
* {
|
|
* // initialize the GStreamer library
|
|
* gst_init (&argc, &argv);
|
|
* ...
|
|
* }
|
|
* ]|
|
|
*
|
|
* It's allowed to pass two %NULL pointers to gst_init() in case you don't want
|
|
* to pass the command line args to GStreamer.
|
|
*
|
|
* You can also use GOption to initialize your own parameters as shown in
|
|
* the next code fragment:
|
|
*
|
|
* ## Initializing own parameters when initializing gstreamer
|
|
* |[ <!-- language="C" -->
|
|
* static gboolean stats = FALSE;
|
|
* ...
|
|
* int
|
|
* main (int argc, char *argv[])
|
|
* {
|
|
* GOptionEntry options[] = {
|
|
* {"tags", 't', 0, G_OPTION_ARG_NONE, &tags,
|
|
* N_("Output tags (also known as metadata)"), NULL},
|
|
* {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)) {
|
|
* g_print ("Error initializing: %s\n", GST_STR_NULL (err->message));
|
|
* exit (1);
|
|
* }
|
|
* g_option_context_free (ctx);
|
|
* ...
|
|
* }
|
|
* ]|
|
|
*
|
|
* Use gst_version() to query the library version at runtime or use the
|
|
* GST_VERSION_* macros to find the version at compile time. Optionally
|
|
* gst_version_string() returns a printable string.
|
|
*
|
|
* The gst_deinit() call is used to clean up all internal resources used
|
|
* by GStreamer. It is mostly used in unit tests to check for leaks.
