Original commit message from CVS: Patch by: Julien Puydt * ext/raw1394/Makefile.am: * ext/raw1394/gst1394probe.c: (gst_1394_get_guid_array), (gst_1394_property_probe_get_properties), (gst_1394_property_probe_probe_property), (gst_1394_property_probe_needs_probe), (gst_1394_property_probe_get_values), (gst_1394_property_probe_interface_init), (gst_1394_type_add_property_probe_interface): * ext/raw1394/gst1394probe.h: (GST_1394_PROBE_H): * ext/raw1394/gstdv1394src.c: (_do_init), (gst_dv1394src_class_init), (gst_dv1394src_init), (gst_dv1394src_dispose), (gst_dv1394src_set_property), (gst_dv1394src_get_property), (gst_dv1394src_discover_avc_node), (gst_dv1394src_query), (gst_dv1394src_update_device_name): * ext/raw1394/gstdv1394src.h: Implement GstPropertyProbe interface and add "device-name" property, so applications can use this to probe for available devices in the same way they can already with v4lsrc and v4l2src (however horrible this property probe interface may be).
