Source push plugin

[Luis dArquer]

OK, I found the issue finally.

Well, that was wrong. The reason why the next message "Plugin %p ..." did not come up was because the debug level was 5, and LOG messages seem to need 6 at least.

So I write the solution in case it is ever useful for someone.

After debugging it, the issue was I called G_DEFINE_TYPE with *my class'* GType, not the *parent* GType. When the plugin code loaded my plugin, it got stuck at my plugin init function, which calls gst_element_register() only. It was not obvious at first, but the last argument to the gst_element_register() call is GST_TYPE_MYCLASS_SRC, which is a call to a function (_get_type()) that was not properly defined - since the  G_DEFINE_TYPE declaration was not done properly. And for some reason, it got stuck there -no idea why really, but it never returned from the call to _get_type()

Thanks

Luis
