Original commit message from CVS: * ext/a52dec/gsta52dec.c: (gst_a52dec_push), (gst_a52dec_handle_event), (gst_a52dec_chain): Add some debug output. Check that a discont has a valid time associated. * ext/alsa/gstalsasink.c: (gst_alsa_sink_check_event), (gst_alsa_sink_loop): Ignore TAG events. A little extra debug for broken timestamps. * ext/dvdnav/dvdnavsrc.c: (dvdnavsrc_init), (dvdnavsrc_loop), (dvdnavsrc_change_state): Ensure we send a discont to engage the link before we send any other events. * ext/dvdread/dvdreadsrc.c: (dvdreadsrc_init), (dvdreadsrc_finalize), (_close), (_open), (_seek_title), (_seek_chapter), (seek_sector), (dvdreadsrc_get), (dvdreadsrc_uri_get_uri), (dvdreadsrc_uri_set_uri): Handle URI of the form dvd://title[,chapter[,angle]]. Currently only dvd://title works in totem because typefinding sends a seek that ends up going back to chapter 1 regardless. * ext/mpeg2dec/gstmpeg2dec.c: * ext/mpeg2dec/gstmpeg2dec.h: Output correct timestamps and handle disconts. * ext/ogg/gstoggdemux.c: (get_relative): Small guard against a null dereference. * ext/pango/gsttextoverlay.c: (gst_textoverlay_finalize), (gst_textoverlay_set_property): Free memory when done. Don't call gst_event_filler_get_duration on EOS events. Use GST_LOG and GST_WARNING instead of g_message and g_warning. * ext/smoothwave/gstsmoothwave.c: (gst_smoothwave_init), (draw_line), (gst_smoothwave_dispose), (gst_sw_sinklink), (gst_sw_srclink), (gst_smoothwave_chain): Draw solid lines, prettier colours. * gst/mpeg2sub/gstmpeg2subt.c: (gst_mpeg2subt_init): Add a default palette that'll work for some movies. * gst/mpegstream/gstdvddemux.c: (gst_dvd_demux_init), (gst_dvd_demux_handle_dvd_event), (gst_dvd_demux_send_discont), (gst_dvd_demux_send_subbuffer), (gst_dvd_demux_reset): * gst/mpegstream/gstdvddemux.h: * gst/mpegstream/gstmpegdemux.c: (gst_mpeg_demux_send_discont), (gst_mpeg_demux_parse_syshead), (gst_mpeg_demux_parse_pes): * gst/mpegstream/gstmpegparse.c: (gst_mpeg_parse_init), (gst_mpeg_parse_handle_discont), (gst_mpeg_parse_parse_packhead): * gst/mpegstream/gstmpegparse.h: Use PTM/NAV events when for timestamp adjustment when connected to dvdnavsrc. Don't use many discont events where one suffices. * gst/playback/gstplaybasebin.c: (group_destroy), (gen_preroll_element), (gst_play_base_bin_add_element): * gst/playback/gstplaybasebin.h: Make sure we remove subtitles from the same bin we put them in. * gst/subparse/gstsubparse.c: (convert_encoding), (parse_subrip), (gst_subparse_buffer_format_autodetect), (gst_subparse_change_state): Fix some memleaks and invalid accesses. * gst/typefind/gsttypefindfunctions.c: (ogganx_type_find), (oggskel_type_find), (cmml_type_find), (plugin_init): Some typefind functions for Annodex v3.0 files * gst/wavparse/gstwavparse.h: GstRiffReadClass is the correct parent class.
