27 * @short_description: Debugging and logging facilities
28 * @see_also: #gstreamer-gstconfig, #gstreamer-Gst for command line parameters
29 * and environment variables that affect the debugging output.
31 * GStreamer's debugging subsystem is an easy way to get information about what
32 * the application is doing. It is not meant for programming errors. Use GLib
33 * methods (g_warning and friends) for that.
35 * The debugging subsystem works only after GStreamer has been initialized
36 * - for example by calling gst_init().
38 * The debugging subsystem is used to log informational messages while the
39 * application runs. Each messages has some properties attached to it. Among
40 * these properties are the debugging category, the severity (called "level"
41 * here) and an optional #GObject it belongs to. Each of these messages is sent
42 * to all registered debugging handlers, which then handle the messages.
43 * GStreamer attaches a default handler on startup, which outputs requested
46 * Messages are output by using shortcut macros like #GST_DEBUG,
47 * #GST_CAT_ERROR_OBJECT or similar. These all expand to calling gst_debug_log()
48 * with the right parameters.
49 * The only thing a developer will probably want to do is define his own
50 * categories. This is easily done with 3 lines. At the top of your code,
52 * the variables and set the default category.
55 * GST_DEBUG_CATEGORY_STATIC (my_category); // define category (statically)
56 * &hash;define GST_CAT_DEFAULT my_category // set as default
59 * After that you only need to initialize the category.
62 * GST_DEBUG_CATEGORY_INIT (my_category, "my category",
63 * 0, "This is my very own");
66 * Initialization must be done before the category is used first.
68 * in their plugin_init function, libraries and applications should do that
69 * during their initialization.
71 * The whole debugging subsystem can be disabled at build time with passing the
72 * --disable-gst-debug switch to configure. If this is done, every function,
73 * macro and even structs described in this file evaluate to default values or
75 * So don't take addresses of these functions or use other tricks.
76 * If you must do that for some reason, there is still an option.
78 * subsystem was compiled out, #GST_DISABLE_GST_DEBUG is defined in
80 * so you can check that before doing your trick.
81 * Disabling the debugging subsystem will give you a slight (read: unnoticeable)
82 * speed increase and will reduce the size of your compiled code. The GStreamer
83 * library itself becomes around 10% smaller.
85 * Please note that there are naming conventions for the names of debugging
86 * categories. These are explained at GST_DEBUG_CATEGORY_INIT().
