+ * 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.
