Andy Wingo cca414a9b5 ext/vorbis/vorbisparse.c (gst_vorbis_parse_init)
Original commit message from CVS:
2006-03-31  Andy Wingo  <wingo@pobox.com>

* ext/vorbis/vorbisparse.c (gst_vorbis_parse_init)
(vorbis_parse_sink_event): Add an event function to flush our
state on a seek, and to drain buffers on a premature EOS.
(vorbis_parse_push_headers, vorbis_parse_clear_queue)
(vorbis_parse_push_buffer, vorbis_parse_drain_queue_prematurely)
(vorbis_parse_chain, vorbis_parse_queue_buffer)
(vorbis_parse_drain_queue): Queue up buffers until we can set
their timestamps and granulepos values.

* ext/vorbis/vorbisparse.h: Include the vorbis decoder headers,
and keep track of data needed for deriving granulepos and
timestamps for buffers.
