[gst-devel] HELP: how to using c to implement this ?

[Freeman Zhang]

Is it in this way?

                GstElement* filesrc = gst_element_factory_make("filesrc",
"filesrc");
                  g_object_set(G_OBJECT(filesrc), "location", cmd->filename,
NULL);

GstCaps *caps = gst_caps_from_string("audio/x-alaw, channels=1, rate=8000");
g_assert(caps != NULL);
decoder = gst_element_factory_make("alawdec", "decoder");
res = gst_element_link_filtered (filesrc, decoder, caps);
g_assert(res == TRUE);


But it return:
                         gst_element_link_pads_filtered: assertion
`GST_IS_BIN (parent)' failed


Thanks
