+ * configure.ac:
+ Add dvdlpcmdec
+
+ * ext/mpeg2dec/gstmpeg2dec.c: (gst_mpeg2dec_reset),
+ (free_all_buffers), (gst_mpeg2dec_alloc_buffer):
+ Don't push buffers if the src pad isn't negotiated yet.
+
+ * gst/audioconvert/gstaudioconvert.c:
+ (gst_audio_convert_buffer_to_default_format),
+ (gst_audio_convert_buffer_from_default_format):
+ Add support for 24-bit width.
+
+ * gst/dvdlpcmdec/.cvsignore:
+ * gst/dvdlpcmdec/Makefile.am:
+ * gst/dvdlpcmdec/gstdvdlpcmdec.c: (gst_dvdlpcmdec_get_type),
+ (gst_dvdlpcmdec_base_init), (gst_dvdlpcmdec_class_init),
+ (gst_dvdlpcm_reset), (gst_dvdlpcmdec_init), (gst_dvdlpcmdec_link),
+ (gst_dvdlpcmdec_chain), (gst_dvdlpcmdec_change_state),
+ (plugin_init):
+ * gst/dvdlpcmdec/gstdvdlpcmdec.h:
+ New decoder for rearranging DVD LPCM into our audio/x-raw-int
+ format. Needs support for the channels maps if someone can find
+ a DVD LPCM track with > 2 channels.
+
+ * gst/mpegstream/gstdvddemux.c: (gst_dvd_demux_handle_dvd_event),
+ (gst_dvd_demux_send_discont), (gst_dvd_demux_handle_discont),
+ (gst_dvd_demux_get_audio_stream), (gst_dvd_demux_process_private):
