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 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
60  *  of events.
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
70  *  ASCII characters.
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.
