[gst-devel] GStreamer-CRITICAL **: gst_bin_add: assertion `GST_IS_ELEMENT (element)' failed

[Guilherme]

I found the gst_pad_add_data_probe();

I might create a function to manipulate data passing through the 
sink-pad I want.

However, I need to get the name of the pad, but Ive my elements linked with:

    gst_element_link_many (source, filesink, NULL);




Tks!
