Original commit message from CVS: * gst/asfdemux/asfheaders.h: * gst/asfdemux/gstasfdemux.c: (gst_asf_demux_get_obj_stream), (gst_asf_demux_process_stream), (gst_asf_demux_process_language_list), (gst_asf_demux_process_ext_stream_props), (gst_asf_demux_process_queued_extended_stream_objects), (gst_asf_demux_process_object), (gst_asf_demux_change_state): * gst/asfdemux/gstasfdemux.h: Parse extended stream properties objects and stream objects hidden inside them (but delay creation of the appropriate pads until after all the 'normal' stream objects have been dealt with) (#343763). Also parse language list object.
