Original commit message from CVS: 2005-12-08 Martin Soto <martinsoto@users.sourceforge.net> * gst/mpegstream/gstdvddemux.c (gst_dvd_demux_handle_newsegment): Properly handle non contiguous VOBUs by adding the segment accum field to the adjust value. * gst/mpegstream/gstdvddemux.c (gst_dvd_demux_class_init) (gst_dvd_demux_init, gst_dvd_demux_handle_newsegment): Extend handle_newsegment to prevent sending actual newsegment events and use tiemstamp rewriting instead. (gst_dvd_demux_handle_dvd_event): Don't send a newsegment after dvd-lang-codes. * gst/mpegstream/gstmpegparse.c (gst_mpeg_parse_handle_newsegment) (gst_mpeg_parse_event): * gst/mpegstream/gstmpegparse.h (struct _GstMPEGParseClass): Add a new parameter to handle_newsegment to allow controlling whether newsegment events are forwarded or not. * gst/mpegstream/gstdvddemux.c (gst_dvd_demux_init) (gst_dvd_demux_handle_dvd_event, gst_dvd_demux_send_subbuffer) (gst_dvd_demux_reset): last_end_ptm and discont_time aren't necessary anymore, since timestamp adjustment is now replaced by newsegment events. (gst_dvd_demux_init): Prevent MPEGParse from adjusting timestamps. * gst/mpegstream/gstdvddemux.h: * gst/mpegstream/gstdvddemux.c (gst_dvd_demux_handle_dvd_event): Don't handle dvd-nav-packet events anymore, since the are now replaced by standard newsegment events. * gst/mpegstream/gstdvddemux.c (gst_dvd_demux_init) (gst_dvd_demux_handle_dvd_event, gst_dvd_demux_send_subbuffer) (gst_dvd_demux_change_state): * gst/mpegstream/gstdvddemux.h: Get rid of the ignore_next_newmedia_discont hack. * gst/mpegstream/gstdvddemux.c (gst_dvd_demux_class_init) (gst_dvd_demux_handle_newsegment): * gst/mpegstream/gstmpegdemux.c (gst_mpeg_demux_class_init) (gst_mpeg_demux_handle_newsegment): Don't override handle_newsegment anymore. It was only necessary to handle NEWMEDIA events. * gst/mpegstream/gstdvddemux.c (gst_dvd_demux_process_event) (gst_dvd_demux_handle_dvd_event, gst_dvd_demux_set_cur_audio) (gst_dvd_demux_set_cur_subpicture): Reactivate handling of DVD events. * gst/mpegstream/gstmpegparse.c (normal_seek) (gst_mpeg_parse_handle_src_event) (gst_mpeg_parse_handle_src_query): First attempt at reenabling seek. * gst/mpegstream/gstmpegparse.h: * gst/mpegstream/gstmpegparse.c (gst_mpeg_parse_init) (gst_mpeg_parse_update_streaminfo) (gst_mpeg_parse_get_rate) (gst_mpeg_parse_convert, gst_mpeg_parse_get_src_query_types) (gst_mpeg_parse_handle_src_query): * gst/mpegstream/gstmpegdemux.c (gst_mpeg_demux_new_output_pad): Make queries work again. * gst/mpegstream/gstmpegparse.c (gst_mpeg_parse_reset) (gst_mpeg_parse_handle_newsegment) (gst_mpeg_parse_send_newsegment, gst_mpeg_parse_pad_added) (gst_mpeg_parse_chain, gst_mpeg_parse_handle_src_event): * gst/mpegstream/gstmpegparse.h (struct _GstMPEGParse): Get rid of the newsegment_pending attribute, and rely instead on proper timestamp adjustment. * gst/mpegstream/gstmpegparse.c (gst_mpeg_parse_get_src_event_masks): Erase. * gst/mpegstream/gstmpegparse.c (gst_mpeg_parse_init): Initialize fields before creating pads to prevent the pad creation callback from failing. (gst_mpeg_parse_reset): Initialize new fields, and change initialization order to match the order in the structure. (gst_mpeg_parse_handle_newsegment): Forward new segment events whenever possible, and update the current segment. (gst_mpeg_parse_send_newsegment): Update the current segment and pending_newsegment. (gst_mpeg_parse_pad_added): Use the current segment to send newsegment events to new pads. (gst_mpeg_parse_chain): Properly add adjust time to sent buffers and events. Properly update newsegment_pending. * gst/mpegstream/gstmpegparse.h (struct _GstMPEGParse): New fields do_adjust and current_segment. * gst/mpegstream/gstmpegdemux.c: * gst/mpegstream/gstdvddemux.c: * gst/mpegstream/gstmpegparse.h: Rename handle_discont virtual method to handle_newsegment. Erase some (already commented out support) for old NEW_MEDIA events. * gst/mpegstream/gstmpegparse.h (struct _GstMPEGParse): * gst/mpegstream/gstmpegparse.c (gst_mpeg_parse_init) (gst_mpeg_parse_reset, gst_mpeg_parse_handle_discont) (gst_mpeg_parse_pad_added, gst_mpeg_parse_parse_packhead) (gst_mpeg_parse_event, gst_mpeg_parse_chain): Erase the "pending_scr" field, and replace it by a slightly different handling of the current SCR. Document code blocks in parse_packhead and chain.
