Original commit message from CVS: * gst/subparse/gstsubparse.c: (parser_state_init), (gst_sub_parse_format_autodetect), (handle_buffer): * gst/subparse/gstsubparse.h: * tests/check/elements/subparse.c: (test_tmplayer_style3b): Limit duration to a maximum of five seconds for tmplayer format where we can guess the duration only from the timestamp of the next line of text. We don't want to show a text for eternities just because nothing else is being said for a while.
