/**
* 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 occurred
* 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_error.
* @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_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.
* @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 running as expected
* should never output anything else but LOG messages whilst processing data.
* Use this log level to log recurring information in chain functions and
* loop functions, for example.
* @GST_LEVEL_TRACE: Tracing-related messages.
* 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.
* @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.
