Revision history for Audio::Scan
Note: Bug numbers refer to bugs at http://bugs.slimdevices.com
1.01 2018-07-09
- Added Opus codec support. (Jeff Muizelaar)
- ADTS: RT #124525, fixed incorrect duration calcuation due to off-by-one error
in frame counter.
- Added missing license meta name. (manwar)
1.00 2018-04-21
- Fixed parsing of DSF files with more than 2 channels.
0.99 2017-11-24
- Fixed a bug where an incorrect audio offset was returned when using
NO_ARTWORK and reading a file with an ID3v2.2 or v2.3 unsynchronization bit
set. The artwork in this type of file is only available when scanning in
normal mode (without NO_ARTWORK).
- Added id3_was_unsynced => 1 to the info section for v2.2/v2.3 files with the
whole-tag unsync bit set. This type of tag is generally harmful to parser performance,
so this flag might be useful if you want to find and upgrade this type of tag to v2.4.
- DSF: WAV_BLOCK_SIZE was being used instead of DSF_BLOCK_SIZE. (Kimmo Taskinen)
- ID3: Support for reading ID3 tags located >4GB into a file, such as in very large
DSF files. (Kimmo Taskinen)
- WavPack: Read correct samplerate and bits_per_sample for DSD files. (Kimmo Taskinen)
- DSF/DFF: added bitrate to info hash.
0.98 2017-04-28
- RT #119101, stop including MYMETA files in the tarball.
0.97 2017-04-27
- WAV: GH #2, fixed an integer overflow error that could result in an incorrect song_length_ms
for >16-bit files.
0.96 2016-11-21
- Ogg: RT #118888, fixed crash when trying to read Vorbis comments in an
incorrectly framed file with a bad terminal header page.
- Removed hints/darwin.pl, don't try to be smarter than Perl about how to build things.
- Fixed various minor compiler warnings output by the latest clang on macOS.
0.95 Unreleased community build
- Improved DFF parsing for files which end with corrupted chunk. (Adrian Smith)
- Improved ID3 support for DFF files. (Adrian Smith)
0.94 Unreleased community build
- DSF/DFF: Support dsd file scanning for dsd and dsdiff files. (Kimmo Taskinen)
- AIFF: Fixed scanning of 24 bit files. (Adrian Smith)
0.93 2011-09-14
- ASF: Support seeking in a file without an ASF_Index object.
- Don't use MAX_PATH because this limits path names to only 260 chars on Win32.
0.92 2011-09-09
- Added $info->{jenkins_hash} which is a 32-bit hash value of the
filename + mtime + file size.
- MP4: Get correct HE-AAC samplerate values from esds.
- ADTS AAC: Add support for .adts file extension.
0.91 2011-09-06
- MP3, MP4, WMA, WAV, AIFF, ADTS AAC: Added DLNA audio profile detection as
$info->{dlna_profile}.
0.90 2011-08-03
- ID3: Bug 17392, fixed APIC offset calculation for non-MP3 files such as AIFF
and WAV where the tag does not live at the front of the file.
0.89 2011-08-03
- APE: Bug 15895, better handling if we have a broken APE tag and run out of
tag data. (Adrian Smith)
- WMA: Bug 17355, fixed WM/Picture offset calculation when artwork is stored in the
Header Extension/Metadata Library block.
- WMA: Added output warning when trying to seek in a file without ASF_Index.
- Switched aac.t to Test::Warn instead of manual STDERR redirection.
0.88 2011-07-20
- ADTS AAC: Check first 2-3 frames to avoid false syncs.
- OSX: Xcode 4 doesn't include the 10.5 SDK, so check for this before using it.
- Win32: Display better error messages when unable to read from files.
- MP3, AAC, MPC: Bug 17173: Cleaned up several places where invalid memory reads could occur.
0.87 2011-03-21
- AAC: Bug 16874, Fixed infinite loop that could occur when reading a truncated
ADTS stream.
- Win32: Fixed MSVC compilation error in mp3.c.
0.86 2011-03-18
- MP3: Require first 3 frames to have matching samplerate and channel values.
- MP3: Fixed bug where info->{vbr} would not be set if a file had a Xing frame
but no LAME data.
- MP3: Handle case where ID3 tag indicates an extended header is present but no
actual header exists.
0.85 2010-09-08 23:40:00
- Changed audio_md5 to use bytes from middle of file instead of the start,
to reduce chance of false matches due to padding or silence. Added new
md5_offset option to override the default location used for MD5.
- MP4: Fixed incorrect COVR_offset calculation.
- FLAC: Fixed a bug where artwork could be seen as invalid if the picture header
wasn't fully buffered.
- FLAC: Use existing MD5 value if available for audio_md5.
- FLAC, INCOMPATIBLE CHANGE: info 'md5' value changed to 'audio_md5'.
0.84 2010-08-27 19:10:00
- Added an optional audio_md5 info value, this is the MD5 checksum of the
first N audio bytes of the file. This is useful in determining if a file
is the same even when tags have been changed. See the documentation for details.
- Added audio_size info value to all formats.
- Added image offset values in AUDIO_SCAN_NO_ARTWORK mode for some formats, so
image data may be extracted directly from the file if needed. See the
documentation for specific details.
- AAC: Fixed samplerate values for AACplus files. The samplerate in the header
needs to be doubled to obtain the actual playback samplerate.
- ID3: Bug 16452, Don't add null strings as array entries for T* frames.
0.83 2010-06-10 14:15:00
- APE: Tag could be ignored when ID3v1 tag is present.
- Fixed error handling for invalid RVAD tags.
- Win32: Added binmode for all open files and filehandles.
0.82 2010-05-24 13:15:00
- RT 57664: ID3: Add checks to avoid reading too much inside an invalid frame.
- FLAC: Seeking bug fixes.
0.81 2010-05-15 10:40:00
- Fixed broken boolean values.
0.80 2010-05-14 23:15:00
- ID3: Fixed unsynchronisation of v2.2/v2.3 tags.
- FLAC: Fixed several seeking bugs and improved seeking algorithm.
- MP3: Subtract LAME encoder delay/padding from total samples to obtain more
accurate song duration value.
0.79 2010-04-27 14:30:00
- ID3: Bug 16079, fixed crash when reading empty TCON tag.
- Bug 16095, workaround Win32+filehandle bug where file pos could sometimes
be off-by-one after a PerlIO_read.
0.78 2010-04-16 15:45:00
- ASF: Fixed various issues when seeking, now uses the ASF_Index object correctly.
- ASF: Refactored to clean up the code and make it more efficient.
- ID3: Bug 16073, properly handle illegal zero-byte frames.
0.77 2010-04-14 11:30:00
- PerlIO_seek with SEEK_END sometimes does not work correctly, changed all seeks
to use SEEK_SET instead.
0.76 2010-04-14 10:30:00
- APE: Bug 15992, fixed reading of APE tags when file also has a Lyricsv2 tag.
- APE: Bug 16056, fixed reading of APE tags with certain kinds of invalid tags.
0.75 2010-04-02 15:50:00
- ID3: Really fixed empty text field bug this time.
0.74 2010-04-02 12:15:00
- ID3: Fixed bug where an empty text field could contain the text from the
previous frame.
0.73 2010-03-31 12:30:00
- Added find_frame_fh_return_info method for MP4 seeking from a filehandle.
0.72 2010-03-31 10:50:00
- Fixed bug in reading unsynchronized APIC frames, the APIC data returned was not
the correct size.
- Fixed Mac hints file to work properly on OSX Server 10.6.
0.71 2010-03-30 00:00:00
- Added find_frame_return_info method for MP4 that returns the seek offset as well
as a rewritten header that can be placed before the seeked audio to construct a
valid bitstream.
0.70 2010-03-23 19:00:00
- 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.
0.62 2010-03-02 12:00:00
- INCOMPATIBLE CHANGE: Ogg Vorbis COVERART tags are now translated to an
ALLPICTURES block and are base64-decoded.
- Added support for new Ogg Vorbis cover art tag, METADATA_BLOCK_PICTURE. Data
is returned in the same ALLPICTURES array as for FLAC.
0.61 2010-02-23 22:50:00
- RT 53118: Fixed crash under Perl 5.11.
- Updated Mac hints file to be more compatible with non-Apple Perl builds.
0.60 2010-02-22 17:45:00
- WavPack 4.x support.
- ID3: Bug 3998, Fixed parsing of multiple TCON genre values in older tag
versions.
- ID3: Parse RGAD frame (replay gain adjustment).
- APE: Fixed bug where a trailing null could be read from tags.
- FLAC: Calculate correct duration/bitrate for files with bad header
information.
- WAV: Ignore chunks SAUR, PAD, and otom.
0.59 2010-02-08 15:30:00
- MP4: Bug 15656, read channels and bits_per_sample for ALAC files.
- APE: Bug 15324, read APEv2 tags that don't contain a header.
- APE: Fixed reading of binary tag data.
- APE: Support for reading special "Cover Art (Front)" tag.
0.58 2010-01-28 12:30:00
- MP4: Bug 15262, Don't overwrite song_length_ms from individual tracks if it was
found in the mvhd box.
0.57 2010-01-12 21:40:00
- Vorbis: Fixed parsing of files with large comment headers containing >128
( run in 1.746 second using v1.01-cache-2.11-cpan-39bf76dae61 )
