35 * @GST_LEVEL_NONE: No debugging level specified or desired. Used to deactivate
37 * @GST_LEVEL_ERROR: Error messages are to be used only when an error occured
38 * that stops the application from keeping working correctly.
39 * An examples is gst_element_error, which outputs a message with this priority.
40 * It does not mean that the application is terminating as with g_errror.
41 * @GST_LEVEL_WARNING: Warning messages are to inform about abnormal behaviour
42 * that could lead to problems or weird behaviour later on. An example of this
43 * would be clocking issues ("your computer is pretty slow") or broken input
44 * data ("Can't synchronize to stream.")
45 * @GST_LEVEL_INFO: Informational messages should be used to keep the developer
46 * updated about what is happening.
47 * Examples where this should be used are when a typefind function has
48 * successfully determined the type of the stream or when an mp3 plugin detects
49 * the format to be used. ("This file has mono sound.")
50 * @GST_LEVEL_DEBUG: Debugging messages should be used when something common
51 * happens that is not the expected default behavior.
52 * An example would be notifications about state changes or receiving/sending of
54 * @GST_LEVEL_LOG: Log messages are messages that are very common but might be
55 * useful to know. As a rule of thumb a pipeline that is iterating as expected
56 * should never output anzthing else but LOG messages.
57 * Examples for this are referencing/dereferencing of objects or cothread switches.
58 * @GST_LEVEL_COUNT: The number of defined debugging levels.
60 * The level defines the importance of a debugging message. The more important a
61 * message is, the greater the probability that the debugging system outputs it.
77 * Defines the default debugging level to be used with GStreamer. It is normally
78 * set to #GST_LEVEL_NONE so nothing get printed.
79 * As it can be configured at compile time, developer builds may chose to
80 * override that though.
81 * You can use this as an argument to gst_debug_set_default_threshold() to
82 * reset the debugging output to default behaviour.

324 * If you define a category for a plugin or a feature of it, name the category

326 * name the category "filesrc". Use lowercase letters only.
327 * If you define more than one category for the same element, append an

331 * If you create a library or an application using debugging categories, use a
332 * common prefix followed by an underscore for all your categories. GStreamer
