39 * @GST_LEVEL_NONE: No debugging level specified or desired. Used to deactivate
41 * @GST_LEVEL_ERROR: Error messages are to be used only when an error occured
42 * that stops the application from keeping working correctly.
43 * An examples is gst_element_error, which outputs a message with this priority.
44 * It does not mean that the application is terminating as with g_errror.
45 * @GST_LEVEL_WARNING: Warning messages are to inform about abnormal behaviour
46 * that could lead to problems or weird behaviour later on. An example of this
47 * would be clocking issues ("your computer is pretty slow") or broken input
48 * data ("Can't synchronize to stream.")
49 * @GST_LEVEL_INFO: Informational messages should be used to keep the developer
50 * updated about what is happening.
51 * Examples where this should be used are when a typefind function has
52 * successfully determined the type of the stream or when an mp3 plugin detects
53 * the format to be used. ("This file has mono sound.")
54 * @GST_LEVEL_DEBUG: Debugging messages should be used when something common
55 * happens that is not the expected default behavior.
56 * An example would be notifications about state changes or receiving/sending of
58 * @GST_LEVEL_LOG: Log messages are messages that are very common but might be
59 * useful to know. As a rule of thumb a pipeline that is iterating as expected
60 * should never output anzthing else but LOG messages.
61 * Examples for this are referencing/dereferencing of objects or cothread switches.
62 * @GST_LEVEL_FIXME: Fixme messages are messages that indicate that something
63 * in the executed code path is not fully implemented or handled yet. Note
64 * that this does not replace proper error handling in any way, the purpose
65 * of this message is to make it easier to spot incomplete/unfinished pieces
66 * of code when reading the debug log. (Since: 0.10.23)
67 * @GST_LEVEL_MEMDUMP: memory dump messages are used to log (small) chunks of
68 * data as memory dumps in the log. They will be displayed as hexdump with
69 * ASCII characters. (Since: 0.10.23)
70 * @GST_LEVEL_COUNT: The number of defined debugging levels.
72 * The level defines the importance of a debugging message. The more important a
73 * message is, the greater the probability that the debugging system outputs it.
84 GST_LEVEL_MEMDUMP = 9,
92 * Defines the default debugging level to be used with GStreamer. It is normally
93 * set to #GST_LEVEL_NONE so nothing get printed.
94 * As it can be configured at compile time, developer builds may chose to
95 * override that though.
96 * You can use this as an argument to gst_debug_set_default_threshold() to
97 * reset the debugging output to default behaviour.
