Original commit message from CVS: * gst/flv/gstflvdemux.c: (gst_flv_demux_cleanup), (gst_flv_demux_loop), (gst_flv_demux_handle_seek_push), (gst_flv_demux_handle_seek_pull), (gst_flv_demux_sink_event), (gst_flv_demux_dispose), (gst_flv_demux_init): * gst/flv/gstflvdemux.h: * gst/flv/gstflvparse.c: (gst_flv_parse_tag_audio), (gst_flv_parse_tag_video), (gst_flv_parse_tag_timestamp): Put the GstSegment directly into the instance struct instead of allocating and free'ing it again. Push tags already if only one pad was added, no need to wait for the second one. When generating our index set has_video and has_audio if we find video or audio in case the FLV header has incorrect data.
