That 'video/quicktime' string gets translated to a 'capsfilter'
element by gst-launch with its 'caps' property set to a GstCaps object
corresponding to 'video/quicktime'. You'll need to do something like:

capsfilter = gst_element_factory_make ("capsfilter", NULL);
caps = gst_caps_from_string ("video/quicktime");
g_object_set (capsfilter, "caps", caps, NULL);
gst_caps_unref (caps);
