- * Define this to debug your debug log messages and make gcc spew warnings
- * if printf format string and arguments don't match up (this is usually
- * not the case when libc and gcc are used because printf format warnings
- * have to be disabled when the printf extension mechanism is in use).
- *
- * Note that using this option disables 'pretty logging' of GStreamer objects
- * like caps, tags, structures, events, pads etc., so that only their address
- * will be printed in the log.
- *
- * This define only disables use of the special registered printf format
- * extensions in the code compiled with it defined. It does not stop
- * GStreamer from registering these extensions in the first place if it
- * was compiled against a libc that supports this.
- *
- * (not official API)
