Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Changed

• ID3v2: Discard empty frames, rather than error
• APE: Allow empty tag items
  • Rather than error on empty items, they will just be discarded

Fixed

• Pictures: Treat "image/jpg" as MimeType::Jpeg (PR)
• MP3:
  • Properly validate the contents of Xing/LAME/VBRI headers (issue)
    • A header with any field zeroed out would result in a division by zero panic
  • Fix duration estimation for files with Xing headers without the necessary flags
• FLAC: Fix property reading of zero-length files (issue)
• Vorbis Comments: Fix reading of vendor strings with invalid mixed UTF-8 and UTF-16 encodings
• ID3v2:
  • Fix reading of zero-size tags
  • Attempt to read invalid v2 frame IDs in v3 tags
    • For some reason, some apps write v2 frame IDs in otherwise valid v3 frames
  • Attempt to decode invalid COMM languages
• MP4:
  • Fix hang when reading invalid padding (issue)
    • If invalid padding was encountered at the end of the file, the reader would get stuck in an infinite loop attempting to read zero size atoms
  • Fallback to bitrate calculation from mdat when necessary (issue)
    • When reading a file that doesn't provide a valid bitrate or duration, a division by zero panic would occur. Now, it attempts to calculate the bitrate from the mdat atom.

0.6.2 - 2022-04-24

Fixed

• MP3: Fix panic when reading files with no MPEG frames (issue)
  • Attempting to read an MP3 file with read_properties = true would result in a panic if the file contained no MPEG frames

0.6.1 - 2022-04-09

Fixed

• MP3: Fix reading of ID3v2 tags with an extended header
  • Restrictions were unnecessarily put on the reader, keeping it from continuing to read into the extended header if it was present
• ID3v2: Fix reading of tags with an extended header
  • The size of the extended header was not being subtracted from the total tag size, causing the reading to continue outside the tag boundaries

0.6.0 - 2022-04-05

Added

• TagItem::{into_key, into_value, consume}
• MP4: Mp4Codec::MP3
• MP4: mp4::AudioObjectType
  • This new type is used in mp4::Mp4Properties, accessible with Mp4Properties::audio_object_type. This provides additional information for the type of audio being dealt with.
• TagExt::clear
  • This allows tags to be cleared of any items or pictures, while retaining any flags (if applicable)
• ID3v2: Respect Id3v2TagFlags::crc when writing
  • Previously, this flag was ignored, but it will now calculate a CRC for the extended header
• ID3v2: FrameValue::Popularimeter
• ItemValue::{into_string, into_binary}
• Tag::take_strings
• TaggedFile now implements AudioFile

Changed

• MP4: Sample rates and channels are now retrieved from the audio specific config (if possible). If the information is invalid or unavailable, the existing value from the mp4a box will be used instead.
• Vorbis Comments: Support non-PNG/JPEG images in PictureInformation::from_picture
  • The method still only supports PNG and JPEG, but rather than error when it encounters an unknown image, it will return PictureInformation::default
• lofty::read_from will now wrap the File in a BufReader
• FLAC: FLAC now has its own module at lofty::flac
• ID3v2: FrameValue is now #[non_exhaustive]
• TagType::remove_from now works for ID3v2 tags in APE and FLAC files
  • This previously verified that the FileType supported the tag. It now has special exceptions for these formats to allow stripping out these unsupported tags
• MP4: Renamed AdvisoryRating::None to AdvisoryRating::Inoffensive
• Renamed TaggedFile::remove_tag to TaggedFile::take
• Vorbis Comments: VorbisComments::insert_picture now accepts a user provided PictureInformation
• Vorbis Comments: Rename VorbisComments::{get_item, insert_item, remove_key} to VorbisComments::{get, insert, remove}
• Vorbis Comments: VorbisComments::remove now returns an iterator over the removed items

Fixed

• MP4: Non-full meta atoms are now properly handled.

  • It is possible for these to be a regular atom (no version or flags). This information was assumed to be present and would get skipped, which would affect the reading of subsequent atoms.

    This behavior has been noticed by:

    • https://leo-van-stee.github.io/
    • https://github.com/axiomatic-systems/Bento4/blob/v1.6.0-639/Source/C%2B%2B/Core/Ap4ContainerAtom.cpp#L60
    • https://github.com/taglib/taglib/issues/1041
• MP4: Properly search for soun atom
  • The search wasn't adding read bytes correctly, but tests passed due to the atom being immediately available. It would attempt to read until it reached an EOF if it managed to make it through multiple iterations.
• FLAC: Support files with an ID3v2 tag
  • This will be read only just like APE, but will allow such files to be read
• ID3v2: Fix writing certain proprietary Apple frames
  • When writing, frame IDs are verified with their content. The Apple specific frames "MVNM" and "MVIN" were missing, causing an error if they were written with their proper type (FrameValue::Text)
• ID3v2: Stop writing a BOM for TextEncoding::UTF16BE

0.5.3 - 2022-03-03

Fixed

• OGG: Segment tables are written correctly with data spanning multiple pages (issue)

0.5.2 - 2022-02-26

Added

• MP4: Ilst::{atoms, retain}

Fixed

• ID3v2: The footer flag is written to the tag
• ID3v2: Pictures are written when using Tag

0.5.1 - 2022-02-21

Changed

• MP4: Padding atoms (free) are used when writing
• Opus: Channel count is verified in accordance to the channel mapping family

Fixed

• MP4: meta atoms are written correctly

0.5.0 - 2022-02-20

Added

• Support for Speex files
• TagExt trait to unify tag behavior
• doc_cfg feature for docs.rs
• Fallible allocation with ErrorKind::Alloc to help prevent OOM
• New dependency: cfg-if
• MP3: Emphasis struct (mp3::Emphasis) for use in Mp3Properties
• ID3v2: Respect the footer flag (id3::v2::Id3v2TagFlags::footer) when writing
• MP4: Constants for all well-known data types (mp4::constants)
• MP4: Support rtng (Parental advisory) atom, with corresponding mp4::AdvisoryRating enum

Changed

• Added #[non_exhaustive] to MimeType
• Added #[non_exhaustive] to PictureType
• Added #[non_exhaustive] to Mp4Codec
• APE: Clarify why ID3v2 is read only
• MP3: No longer error on missing Xing/VBRI header when reading properties
• MP3: Read the entire MPEG frame header, which is exposed in Mp3Properties
• AudioFile now requires Into<TaggedFile>
• MP4: Empty atoms are discarded
• MP4: Variable-size integers are shrunk when writing

Fixed

• MP4: Panic in Mp4File::read_from (commit)
• WAV/AIFF: Chunk reading now makes use of fallible allocation, preventing OOM
• ID3v2: Text is properly encoded when writing
• ID3v2: MVNM and MVIN frames are now treated as text frames
• ID3v2: Text encodings are verified for V2 tags
• MP4: plID atom is properly treated as a 64-bit signed integer (issue)
• MP4: rate and rtng now map to the correct ItemKey
• MP4: Integer pairs are now written correctly
• TagType and FileType are no longer taken by reference in any method

Removed

• ErrorKind::BadExtension
