/**
 * GstDebugLevel:
 * @GST_LEVEL_NONE: No debugging level specified or desired. Used to deactivate
 *  debugging output.
 * @GST_LEVEL_ERROR: Error messages are to be used only when an error occured
 *  that stops the application from keeping working correctly.
 *  An examples is gst_element_error, which outputs a message with this priority.
 *  It does not mean that the application is terminating as with g_errror.
 * @GST_LEVEL_WARNING: Warning messages are to inform about abnormal behaviour
 *  that could lead to problems or weird behaviour later on. An example of this
 *  would be clocking issues ("your computer is pretty slow") or broken input
 *  data ("Can't synchronize to stream.")
 * @GST_LEVEL_INFO: Informational messages should be used to keep the developer
 *  updated about what is happening.
 *  Examples where this should be used are when a typefind function has
 *  successfully determined the type of the stream or when an mp3 plugin detects
 *  the format to be used. ("This file has mono sound.")
 * @GST_LEVEL_DEBUG: Debugging messages should be used when something common
 *  happens that is not the expected default behavior, or something that's
 *  useful to know but doesn't happen all the time (ie. per loop iteration or
 *  buffer processed or event handled).
 *  An example would be notifications about state changes or receiving/sending
 *  of events.
 * @GST_LEVEL_LOG: Log messages are messages that are very common but might be
 *  useful to know. As a rule of thumb a pipeline that is iterating as expected
 *  should never output anything else but LOG messages. Use this log level to
 *  log recurring information in chain functions and loop functions, for
 *  example.
 * @GST_LEVEL_FIXME: Fixme messages are messages that indicate that something
 *  in the executed code path is not fully implemented or handled yet. Note
 *  that this does not replace proper error handling in any way, the purpose
 *  of this message is to make it easier to spot incomplete/unfinished pieces
 *  of code when reading the debug log. (Since: 0.10.23)
 * @GST_LEVEL_TRACE: Tracing-related messages (Since: 0.10.30)
 *  Examples for this are referencing/dereferencing of objects.
 * @GST_LEVEL_MEMDUMP: memory dump messages are used to log (small) chunks of
 *  data as memory dumps in the log. They will be displayed as hexdump with
 *  ASCII characters. (Since: 0.10.23)
 * @GST_LEVEL_COUNT: The number of defined debugging levels.
 *
 * The level defines the importance of a debugging message. The more important a
 * message is, the greater the probability that the debugging system outputs it.
