34 * GstDebugLevel:
35 * @GST_LEVEL_NONE: No debugging level specified or desired. Used to deactivate
36 * debugging output.
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, or something that's
52 * useful to know but doesn't happen all the time (ie. per loop iteration or
53 * buffer processed or event handled).
54 * An example would be notifications about state changes or receiving/sending
55 * of events.
56 * @GST_LEVEL_LOG: Log messages are messages that are very common but might be
57 * useful to know. As a rule of thumb a pipeline that is iterating as expected
58 * should never output anything else but LOG messages. Use this log level to
59 * log recurring information in chain functions and loop functions, for
60 * example.
61 * @GST_LEVEL_FIXME: Fixme messages are messages that indicate that something
62 * in the executed code path is not fully implemented or handled yet. Note
63 * that this does not replace proper error handling in any way, the purpose
64 * of this message is to make it easier to spot incomplete/unfinished pieces
65 * of code when reading the debug log. (Since: 0.10.23)
66 * @GST_LEVEL_TRACE: Tracing-related messages (Since: 0.10.30)
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
70 * ASCII characters. (Since: 0.10.23)
71 * @GST_LEVEL_COUNT: The number of defined debugging levels.
72 *
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.
