Put this at the top of your myfilter.c file after all the includes:

GST_DEBUG_CATEGORY_STATIC (my_filter_debug);
#define GST_CAT_DEFAULT my_filter_debug

and this in your plugin_init function or _get_type() function or so:

GST_DEBUG_CATEGORY_INIT (my_filter_debug, "myfilter", 0, "my filter

Also make sure your application passes the command line arguments to
gst_init() correctly.  If not, use the GST_DEBUG environment variable,

  $ GST_DEBUG=myfilter:5 ./yourapp
