Original commit message from CVS: 2006-01-30 Andy Wingo <wingo@pobox.com> * tests/check/Makefile.am (check_vorbis): Add pipelines/vorbisenc. * ext/vorbis/vorbisenc.c (gst_vorbisenc_buffer_from_packet): Logic updated to timestamp from the first sample, not the last. (gst_vorbisenc_buffer_from_header_packet): New function, takes special care of granulepos and timestamp for header packets. (gst_vorbisenc_chain): Reflow, fix some leaks, and handle the case when the first buffer has a nonzero timestamp. * ext/vorbis/vorbisenc.h (GstVorbisEnc.granulepos_offset) (GstVorbisEnc.subgranule_offset): New members. Take care of the case when the first audio buffer we get has a nonzero timestamp. (GstVorbisEnc.next_ts): Renamed from prev_ts, because now we properly timestamp vorbis buffers with the time of the first sample, not the last. * ext/vorbis/vorbisenc.c (granulepos_to_clocktime): Renamed from vorbis_granule_time_copy -- now it takes the granule/subgranule offset into account. * tests/check/pipelines/vorbisenc.c: New test for correctness of timestamps, durations, and granulepos on buffers produced by vorbisenc.
