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.
