Hello,
I am using the gstreamer-0.10.34. I would like to know how do i get the name of an element factory. I create an element, say GstElement *element; GstElementFactory *factory; element = gst_element_factory_make ("queue2", NULL); factory = gst_element_get_factory (element); I need to query the factory such that it return "queue2" as its name. In an earlier release of gstreamer i used to call: factoryname = GST_ELEMENT_NAME (factory); And i would get the factoryname as "queue2". But in the 0.10.34 release it returns "elementfactoryXXX", where XXX is a random number. I am writing a function to return a reference to am element belonging to a particular factory. Thanks and Regards ~Sameer _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
I just checked up on how gst_bin_get_by_name () call works.
children = gst_bin_iterate_recurse (bin); result = gst_iterator_find_custom (children, (GCompareFunc) compare_name, (gpointer) name); gst_iterator_free (children); And in the compare_name function eq = strcmp (GST_ELEMENT_NAME (element), name); It seems GST_ELEMENT_NAME () is how it is supposed to be done. Looks like something is wrong in my code. Thanks ~Sameer On Fri, Jun 3, 2011 at 9:01 PM, Sameer Naik <[hidden email]> wrote: > Hello, > > I am using the gstreamer-0.10.34.

GST_ELEMENT_NAME on an element will give you the element name. If
that's what you want - great. However, you ASKED for the element factory name. For that, you can use GST_PLUGIN_FEATURE_NAME(elementfactory). Note that you want to call this on the element factory, NOT the element.
