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

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

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
