Audio-Scan-0.70

Changes for version 0.70 - 2010-03-23

  • Replaced libid3tag with a custom ID3 tag parser. libid3tag would read an entire tag into memory, so in files with large embedded artwork this was a huge waste of memory. The new parser will generally never buffer more than about 4K of the file if AUDIO_SCAN_NO_ARTWORK is set. It is also around twice as fast.
  • INCOMPATIBLE CHANGE: ID3 tag elements returned in array form no longer include the encoding type as the first value in the array. Common frames this affects include COMM, APIC, USLT, and others.
  • INCOMPATIBLE CHANGE: find_frame for both MP3 and Ogg Vorbis now take a timestamp in milliseconds. Seeking using a file offset is too ambiguous because of non-audio tag data.
  • Fixed minor bug in Ogg Vorbis bitrate calculation, it was not ignoring the size of the leading tag data when calculating average bitrate.
  • Improved Ogg Vorbis bitrate/duration calculation when file contains multiple logical bitstreams.
  • Added support for old WavPack versions < 4.
  • Changed ASF file_size value to be the actual file size, not the value from within the file metadata which may or may not be correct.
  • Bundled a win32 build of zlib to make compiling on Windows a bit easier.
