[gst-embedded] link/unlink at runtime

[Israel Cepeda]

Hi,
 
I was trying all is in document and few more ideas but I look that it can't unlink the elements, this is an example of mi code:
In the callback when the pad is already blocked I have:
 
padsrc = gst_element_get_pad (source, "src");padsink = gst_element_get_pad (sink, "sink");g_assert (padsrc != NULL);g_assert (padsink != NULL);if (!gst_pad_unlink(padsrc, padsink))  g_warning ("Failed to unlink elements!"); 
any idea why it's not possible to unlink them?
 

 
Best Regards!
