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

[Guilherme]

Even if I use gst_element_get_static_pad I'm unable to specify the pad 
name as the pad was created automatically when I linking the elements with

    gst_element_link_many

;/ Is that possible to retrieve pads even when they are created 
automatically?

Tks!
