Original commit message from CVS: 2004-01-03 Ronald Bultje <rbultje@ronald.bitfreak.net> * gst/mpegstream/gstmpegdemux.c: (gst_mpeg_demux_parse_pes): * gst/mpegstream/gstmpegparse.c: (gst_mpeg_parse_class_init), (gst_mpeg_parse_init): * gst/mpegstream/gstmpegparse.h: Remove clock (which was never provided, i.e. dead code), and also fix integer overflows at high PTS values (see #126967).
