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 occurred
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_error.
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_FIXME: Fixme messages are messages that indicate that something
46 * in the executed code path is not fully implemented or handled yet. Note
47 * that this does not replace proper error handling in any way, the purpose
48 * of this message is to make it easier to spot incomplete/unfinished pieces
49 * of code when reading the debug log.
50 * @GST_LEVEL_INFO: Informational messages should be used to keep the developer
51 * updated about what is happening.
52 * Examples where this should be used are when a typefind function has
53 * successfully determined the type of the stream or when an mp3 plugin detects
54 * the format to be used. ("This file has mono sound.")
55 * @GST_LEVEL_DEBUG: Debugging messages should be used when something common
56 * happens that is not the expected default behavior, or something that's
57 * useful to know but doesn't happen all the time (ie. per loop iteration or
58 * buffer processed or event handled).
59 * An example would be notifications about state changes or receiving/sending
61 * @GST_LEVEL_LOG: Log messages are messages that are very common but might be
62 * useful to know. As a rule of thumb a pipeline that is running as expected
63 * should never output anything else but LOG messages whilst processing data.
64 * Use this log level to log recurring information in chain functions and
65 * loop functions, for example.
66 * @GST_LEVEL_TRACE: Tracing-related messages.
67 * Examples for this are referencing/dereferencing of objects.
68 * @GST_LEVEL_MEMDUMP: memory dump messages are used to log (small) chunks of
69 * data as memory dumps in the log. They will be displayed as hexdump with
71 * @GST_LEVEL_COUNT: The number of defined debugging levels.
73 * The level defines the importance of a debugging message. The more important a
74 * message is, the greater the probability that the debugging system outputs it.
79 GST_LEVEL_WARNING = 2,
86 GST_LEVEL_MEMDUMP = 9,
94 * Defines the default debugging level to be used with GStreamer. It is normally
95 * set to #GST_LEVEL_NONE so nothing get printed.
96 * As it can be configured at compile time, developer builds may chose to
97 * override that though.
98 * You can use this as an argument to gst_debug_set_default_threshold() to
99 * reset the debugging output to default behaviour.
101 #ifndef GST_LEVEL_DEFAULT
102 #define GST_LEVEL_DEFAULT GST_LEVEL_NONE
108 * Defines the maximum debugging level to be enabled at compilation time. By default
109 * it is set such that all debugging statements will be enabled.
111 * If you wish to compile GStreamer and plugins with only some debugging statements
112 * (Such as just warnings and errors), you can define it at compile time to the
113 * maximum debug level. Any debug statements above that level will be compiled out.
