libOgg 1.2.1 and libVorbis 1.3.2 released
Xiph.Org is pleased to announce a full release of libogg 1.2.1 and libvorbis 1.3.2. This is not a coordinated release, it was merely convenient to do a release cycle for both at the same time.
Changes and fixes in the new libogg release include:
- Various build updates (see SVN)
- Add ogg_stream_pageout_fill() to API to allow applications greater explicit flexibility in page sizing.
- Documentation updates including multiplexing description, terminology and API (incl. ogg_packet_clear(), ogg_stream_pageout_fill())
- Correction of a possible buffer overwrite in stream encoding on 32 bit when a single packet exceed 250MB.
- Correction of a read-buffer overrun [without side effects] under similar circumstances.
- Updates to unit testing to work properly with new page spill heuristic.
Changes and fixes in the new libvorbis release include:
- Additional proofing against invalid/malicious streams in floor, residue, and bos/eos packet trimming code (see SVN for details).
- New programming documentation tree for the low-level libvorbis calls
- Correct handling of vorbisfile serial numbers array element  on non-seekable streams
- 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.
- Correct timestamp return for granule positions with high bit set.
- 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 half-rate mode. Also remove requirement that half-rate mode only work with seekable files.
- Fixed a chaining bug in raw_seeks where seeking out of the current link would fail due to not reinitializing the decode machinery.
- Improvement of seeking strategy reduces the necessary number of seek callbacks in an open or seek operation by well over 2/3.
These library releases are ABI and API compatible with previous incarnations of libogg.
