更新LibOgg到1.2.2、更新LibVorbis到1.3.2
libvorbis 1.3.2 (2010-11-01) — “Xiph.Org libVorbis I 20101101 (Schaufenugget)”
- vorbis: additional proofing against invalid/malicious streams in floor, residue, and bos/eos packet trimming code (see SVN for details).
- vorbis: Added programming documentation tree for the low-level calls
- vorbisfile: Correct handling of serial numbers array element [0] on non-seekable streams
- vorbisenc: Back out an [old] AoTuV HF weighting that was first enabled in 1.3.0; there are a few samples where I really don’t like the effect it causes.
- vorbis: return correct timestamp for granule positions with high bit set.
- vorbisfile: the [undocumented] half-rate decode api made no attempt to keep the pcm offset tracking consistent in seeks. Fix and add a testing mode to seeking_example.c to torture test seeking in halfrate mode. Also remove requirement that halfrate mode only work with seekable files.
- vorbisfile: Fix a chaining bug in raw_seeks where seeking out of the current link would fail due to not reinitializing the decode machinery.
- vorbisfile: improve seeking strategy. Reduces the necessary number of seek callbacks in an open or seek operation by well over 2/3.
