| * SECTION:gstinfo |
| * @short_description: Debugging and logging facilities |
| * @see_also: #gst-running for command line parameters |
| * and environment variables that affect the debugging output. |
| * |
| * GStreamer's debugging subsystem is an easy way to get information about what |
| * the application is doing. It is not meant for programming errors. Use GLib |
| * methods (g_warning and friends) for that. |
| * |
| * The debugging subsystem works only after GStreamer has been initialized |
| * - for example by calling gst_init(). |
| * |
| * The debugging subsystem is used to log informational messages while the |
| * application runs. Each messages has some properties attached to it. Among |
| * these properties are the debugging category, the severity (called "level" |
| * here) and an optional #GObject it belongs to. Each of these messages is sent |
| * to all registered debugging handlers, which then handle the messages. |
| * GStreamer attaches a default handler on startup, which outputs requested |
| * messages to stderr. |
| * |
| * Messages are output by using shortcut macros like #GST_DEBUG, |
| * #GST_CAT_ERROR_OBJECT or similar. These all expand to calling gst_debug_log() |
| * with the right parameters. |
| * The only thing a developer will probably want to do is define his own |
| * categories. This is easily done with 3 lines. At the top of your code, |
| * declare |
| * the variables and set the default category. |
| * |[<!-- language="C" --> |
| * GST_DEBUG_CATEGORY_STATIC (my_category); // define category (statically) |
| * #define GST_CAT_DEFAULT my_category // set as default |
| * ]| |
| * After that you only need to initialize the category. |
| * |[<!-- language="C" --> |
| * GST_DEBUG_CATEGORY_INIT (my_category, "my category", |
| * 0, "This is my very own"); |
| * ]| |
| * Initialization must be done before the category is used first. |
| * Plugins do this |
| * in their plugin_init function, libraries and applications should do that |
| * during their initialization. |
| * |
| * The whole debugging subsystem can be disabled at build time with passing the |
| * --disable-gst-debug switch to configure. If this is done, every function, |
| * macro and even structs described in this file evaluate to default values or |
| * nothing at all. |
| * So don't take addresses of these functions or use other tricks. |
| * If you must do that for some reason, there is still an option. |
| * If the debugging |
| * subsystem was compiled out, #GST_DISABLE_GST_DEBUG is defined in |
| * <gst/gst.h>, |
| * so you can check that before doing your trick. |
| * Disabling the debugging subsystem will give you a slight (read: unnoticeable) |
| * speed increase and will reduce the size of your compiled code. The GStreamer |
| * library itself becomes around 10% smaller. |
| * |
| * Please note that there are naming conventions for the names of debugging |
| * categories. These are explained at GST_DEBUG_CATEGORY_INIT(). |
