Original commit message from CVS: * gst/mpegstream/gstmpegdemux.c: * gst/mpegstream/gstmpegdemux.h: Complete overhaul. All DVD specific functionality split to the new dvddemux element. * gst/mpegstream/gstdvddemux.c: * gst/mpegstream/gstdvddemux.h: New demultiplexer for DVD (VOB) streams, derived from mpegdemux. * gst/mpegstream/gstmpegparse.c: Discontinuity handling cleaned up. SCR based timestamp rewriting can be turned off (will probably completely disappear soon). * ext/dvdnav/dvdnavsrc.c: Changes resulting from a few months hacking. General cleanup. All printf statements replaced by debugging messages. Almost complete libdvdnav support. (dvdnavsrc_class_init): Got rid of unnecessary signals (replaced by events. New properties for audio and subpicture languages. (dvdnavsrc_update_highlight): Now uses events. (dvdnavsrc_user_op): Cleaned up. (dvdnavsrc_get): Renamed to dvdnavsrc_loop (element is now loop based). Lots of cleanup, and propper support for most libdvdnav events. (dvdnavsrc_make_dvd_event): New function. (dvdnavsrc_make_dvd_nav_packet_event): New function. (dvdnavsrc_make_clut_change_event): New function.
