Original commit message from CVS: 2006-01-05 Martin Soto <martinsoto@users.sourceforge.net> * gst/mpegstream/gstmpegparse.c (gst_mpeg_parse_adjust_ts) (gst_mpeg_parse_process_event, gst_mpeg_parse_pad_added): Don't rewrite timestamps in the case segments are being set from upstream, but use timestamps unmodified. Also send proper position values. This allows for correct time display and makes queries work in sink elements. * gst/mpegstream/gstdvddemux.h: * gst/mpegstream/gstdvddemux.c (gst_dvd_demux_init) (gst_dvd_demux_handle_dvd_event, gst_dvd_demux_send_subbuffer): Rename flush_filter to segment_filter, which is better represents what the arreibute does. * gst/mpegstream/gstdvddemux.c (gst_dvd_demux_process_event): Activate segment filtering when a timestamp discontinuity is seen.
