Some encoders write a valid data chunk but with a slightly too-large
declared chunkSize, or place the data chunk beyond the declared RIFF
boundary. The previous behaviour called break, abandoning all remaining
chunks and making the file appear empty to taglib.
Lenient parsers (ffmpeg, QuickTime) handle this case by clamping the
chunk size to the bytes that actually remain in the file. Adopt the
same strategy: when chunkSize would exceed the file length, clamp it
and continue parsing rather than stopping early.
Read, write, and remove Broadcast Audio Extension (BEXT, EBU Tech 3285)
and iXML metadata chunks in WAV files. BEXT is widely used in broadcast
and professional audio for originator, description, time reference, and
loudness metadata. iXML is used by field recorders and DAWs for scene,
take, and track metadata.
MPEG::File::isSupported() scans for frame sync bytes that can appear
in other files, causing them to be misidentified as MP3.
This also includes a test with such a file.
Make AttachedFile immutable. This is consistent with SimpleTag and
Chapter and avoids using attached files which do not have all required
attributes.
Provide methods to insert and remove a single simple tag, so that
they can be modified without setting all of them while still not
exposing internal lists to the API.
Use DATE_RECORDED instead of DATE_RELEASED for year() and the "DATE"
property. This is more consistent with other tag formats, e.g. for ID3v2
"TDRC" is used, which is the recording time.
The C bindings would convert a char* to String using the default
constructor, which uses the Latin1 encoding, breaking when a key
contains a Unicode character (e.g. an ID3v2 comment description).
The involvement/involvee pairs which are supported for TIPL properties
(ARRANGER, ENGINEER, PRODUCER, DJ-MIX, MIX) are left in the TIPL
frame, other pairs are moved to a TMCL frame. This will result in a
consistent behavior for both ID3v2.3 and ID3v2.4 tags produced by
MusicBrainz Picard.
The following user-settable values for CMake are supported:
- TESTS_DIR: Tests directory, is path to unit test data when 'data' is
appended. Can be used to run the unit tests on a target.
- TESTS_TMPDIR: Directory for temporary files created during unit tests,
system tmpdir is used if undefined. Has to be defined on systems
without global temporary directory.
* Add Shorten (SHN) support
* Add `<cmath>` include and use `std::log2`
* Use `uintptr_t` for buffer size calculations
* Work around `byteSwap` not using fixed width types
* Remove four-character codes
* Attempt to fix `static_assert`
* Revert previous commit
* Update `read_uint`* functions
* Use ByteVector for byte swaps
* Use different ByteVector ctor
* Rework variable-length input to use ByteVector
* Rename some variables
* Naming and formatting cleanup
* Add basic Shorten tests
* Rename a constant
* Rename `internalFileType` to `fileType`
* Add documentation on `fileType` meaning
* Add DO_NOT_DOCUMENT guard
* Fix shadowVariable issues reported by cppcheck
cppcheck --enable=all --inline-suppr \
--suppress=noExplicitConstructor --suppress=unusedFunction \
--suppress=missingIncludeSystem --project=compile_commands.json
* Formatting cleanup
* More explicit types
Reason for these changes: getRiceGolombCode(k, uInt32CodeSize) was
called with int k for uint32_t& argument.
There was also a warning from MSVC for line 299:
warning C4267: 'argument': conversion from 'size_t' to 'int'
* Additional explicit types
* Rename `SHN` namespace to `Shorten`
Also rename files to match

If an M4A file contains trailing garbage (e.g. an APE tag at the
end of the file), it was considered invalid since [e21640b].
It is important to make sure that atoms which affect modifications
written by TagLib are valid, otherwise the file might be damaged.
However, in cases where invalid atoms do not affect modifications
(which are only done inside the root level "moov" and "moof"
containers), they can be safely ignored.
This commit allows trailing garbage in M4A files as it is also
accepted in MP3, WAV and DSF files.
Many shadowFunction, some useStlAlgorithm, and others.
