Original commit message from CVS: * ext/mpeg2dec/gstmpeg2dec.c: Don't send things to NULL PAD_PEERs * gst/deinterlace/gstdeinterlace.c: (gst_deinterlace_chain): Copy-on-write the incoming buffer. * gst/mpegstream/gstdvddemux.h: * gst/mpegstream/gstmpegclock.h: * gst/mpegstream/gstmpegdemux.c: (gst_mpeg_demux_parse_syshead), (normal_seek), (gst_mpeg_demux_handle_src_event): * gst/mpegstream/gstmpegdemux.h: * gst/mpegstream/gstmpegpacketize.h: * gst/mpegstream/gstmpegparse.c: (gst_mpeg_parse_update_streaminfo), (gst_mpeg_parse_reset), (gst_mpeg_parse_handle_discont), (gst_mpeg_parse_parse_packhead), (gst_mpeg_parse_loop), (gst_mpeg_parse_get_rate), (gst_mpeg_parse_convert_src), (gst_mpeg_parse_handle_src_query), (gst_mpeg_parse_handle_src_event), (gst_mpeg_parse_change_state): * gst/mpegstream/gstmpegparse.h: * gst/mpegstream/gstrfc2250enc.h: Various changes to the way time is computed that make seeking and total time estimation much better here. Use G_BEGIN/END_DECLS instead of __cplusplus * gst/videocrop/gstvideocrop.c: (gst_video_crop_chain): Use gst_buffer_stamp instead of only copying the TIMESTAMP
