revelo v0.4.6

fix: add banner to revelo-cli README

revelo v0.4.5

fix: add banner to facade crate README for crates.io rendering

revelo v0.4.4

Added

• duration_ms() helper in revelo-core — round-to-nearest duration
  computation from sample counts. Applied to WAV and MP3 parsers for more
  precise output. Ogg retains intentional truncation to match the mediainfo
  oracle.
• STATUS.md — project roadmap and status tracker, linked from the README.
• ## Status and ## License sections added to README.

Fixed

• Banner image URL — crates.io now shows the revelo banner (was a broken
  relative path).

revelo v0.4.3

Added

• Apple MakerNote support — ~17 fields parsed clean-room from the on-disk
  IFD (cross-referenced against ExifTool's printed output, not its tables):
  MakerNoteVersion, AEStable/AETarget/AEAverage, AFStable,
  AccelerationVector, FocusDistanceRange, ContentIdentifier,
  ImageCaptureType, LivePhotoVideoIndex, HDRHeadroom,
  SignalToNoiseRatio, PhotoIdentifier, ColorTemperature, CameraType,
  FocusPosition. The default (BSD) build is unaffected by the GPL
  exiftool-tables feature.
• ICC profile header fields — ProfileCMMType, ProfileVersion,
  ProfileClass, ColorSpaceData, ProfileConnectionSpace, ProfileDateTime,
  PrimaryPlatform, RenderingIntent, DeviceManufacturer/DeviceModel,
  ProfileID/Description/Copyright, MediaWhitePoint, and the RGB matrix
  columns. The profile is located by its acsp signature, so embedded profiles
  (JPEG APP2, HEIC, raw .icc) are read correctly rather than from offset 0.
• Composite/derived fields — ScaleFactor35efl, CircleOfConfusion,
  FieldOfView, HyperfocalDistance, LightValue.
• Extra GPS fields surfaced in text output — GPSSpeed, GPSImgDirection,
  GPSDestBearing, GPSHPositioningError (and their reference tags).

Fixed

• parse_icc read the wrong offset and emitted an empty ICC_Profile : ();
  it now locates the profile correctly and no longer emits a spurious ICC
  section for files without a profile.
• Apple maker notes produced no output because the parser never skipped the
  14-byte Apple iOS header and the hand-written tag table had incorrect IDs;
  both are fixed.
• parse_xmp failed to find the XMP packet embedded in JPEGs (it read from the
  cursor over binary data); it now scans the whole file.
• JPEG camera Model was read past its NUL terminator (e.g. ION230 F →
  ION230).

Changed

• Single EXIF walker. revelo-parsers-tag is now the sole EXIF / GPS /
  maker-note / ICC parser. The JPEG container parser no longer carries a
  duplicate EXIF/TIFF walk — it parses only JPEG structure (geometry, chroma
  subsampling, thumbnail), and the MediaInfo-vocabulary fields
  (Recorded_Date, Encoded_Hardware_*, the photographic <extra> block) are
  derived from the shared tag parse. Verified net-zero against a 104-file
  sample corpus.

revelo v0.4.2

Fixed

• Panic-safety on malformed/truncated input: guard MP4 avcC/hvcC parsing
  against truncated boxes; correct the SCTE-35 splice-header byte offsets and a
  parse_splice_insert off-by-one; checked/saturating size arithmetic in
  AVI/MKV/MP4/MXF (safe on 32-bit wasm32).
• Parsing correctness on valid files: honor TIFF byte order for EXIF
  FLOAT/DOUBLE values; decode ELF e_type/e_machine per the file's endianness;
  read AVC scaling-list delta_scale as signed Exp-Golomb; derive AV1 bit depth
  from color_config(); parse real VVC profile/tier/level and fix VVC RBSP
  emulation-prevention removal; fix infer_raw_format reading Make from the
  wrong stream.
• Exporters: XML-escape values and paths in ebuCore/MPEG-7/PBCore/RevTMD;
  NISO/FIMS now emit the parsed stream fields instead of an empty shell; teletext
  fills fields on partial packets; bound the VOB-PCM LPCM scan.

Changed

• Rewrote per-crate READMEs and added crate-level docs across the workspace; added
  exif/exiftool keywords and richer descriptions for crates.io discoverability.
• Release pipeline now publishes the revelo facade and revelo-exiftool-tables
  (previously omitted from the publish list).

Note

• First crates.io publish of the revelo facade crate.

revelo v0.4.1

Added

• revelo facade crate — a single revelo dependency replaces manually wiring
  revelo-core, revelo-dispatcher, and revelo-parsers-tag. The crate exposes:
  • Metadata::from_file(path) and Metadata::from_bytes(bytes) — detect format,
    parse container/codec metadata, and run EXIF/IPTC/XMP/ICC/C2PA tag extraction
    in one call
  • Typed per-stream accessors: .general(), .video(), .audio(), .text(),
    .image(), .exif(), .iptc(), .xmp() — each yielding (&str, &str) pairs
  • MediaFile type alias for FileAnalyze (the old name continues to work)
  • Metadata::streams() and into_streams() for access to the raw
    StreamCollection
  • Re-exports of revelo_core, revelo_dispatcher, and revelo_parsers_tag
    so dependents get the full API from one crate
  • Pass-through exiftool-tables feature that pulls the GPL/Artistic maker-note
    tables crate

Changed

• README parser and crate counts are now auto-updated as part of the release
  workflow (script runs cargo metadata and counts #[test] annotations).
• Release notes generation strips the v prefix from the tag name before passing
  it to the GitHub CLI.

Fixed

• Homebrew formula pushed to personal tap (vbasky/homebrew-revelo) instead of
  attempting an upstream homebrew-core PR (which cannot be automated reliably).
• Homebrew install command corrected in README to match the personal tap URL.

revelo v0.4.0

Added

• EXIF/IPTC/XMP/ICC/C2PA/MakerNotes promoted to their own stream sections
  (revelo extensions beyond MediaInfo's stream_t), matching how exiftool groups
  metadata by family-0 type rather than folding everything into General. EXIF
  streams from the container parser and the IFD walker are now merged into one.

• IPTC IIM now anchored to the Photoshop 8BIM Image Resource Block (resource
  0x0404) instead of scanning raw bytes — fixes false-positive datasets (e.g. a
  garbage Headline) matched in compressed image data.

• Optional exiftool-tables feature (off by default) — opt in to richer
  maker-note tag names and PrintConv value decoding sourced from ExifTool, for 14
  vendors (Apple, Canon, Casio, DJI, FLIR, FujiFilm, Minolta, Nikon, Olympus,
  Panasonic, Pentax, Samsung, Sigma, Sony). The tables live in a separate
  GPL/Artistic crate revelo-exiftool-tables (generated from ExifTool via
  codegen/extract.pl); the default revelo build stays BSD-2-Clause and uses the
  hand-written clean-room tables. Enabling the feature subjects the resulting
  binary to GPL/Artistic terms.

• Canon maker-note decoding (under exiftool-tables) — ExifTool-derived
  ProcessBinaryData sub-tables (CameraSettings, ShotInfo) are now decoded into
  individual named, value-converted tags. Two correctness fixes make this work on
  real files: the bare-IFD offset is no longer mis-detected when the first tag id
  is 0x0000 (broke every Canon file whose maker note starts that way, e.g. the
  IXUS), and a cross-validated FixBase recovers mis-based maker-note offsets in
  edited/re-muxed files (matching exiftool's "Adjusted MakerNotes base by N").
  Records are accepted only when their self-describing byte-count header validates,
  so a wrong offset decodes nothing rather than garbage. The header-less
  FIRST_ENTRY 0 FocalLength sub-table is decoded only when FixBase confirmed the
  base. The variable-length AFInfo (0x0012) record (NumAFPoints-driven
  AFAreaXPositions[N] etc.) is hand-walked behind an exact total-size match, so a
  mis-laid record decodes nothing. The newer AFInfo2 (0x0026) / AFInfo3 (0x003C,
  SerialData) records — which lead with a self-validating AFInfoSize header and
  carry an AFAreaMode enum plus four [N] arrays — are decoded the same way. For
  Main tags revelo's older bespoke table lacks, the fuller ExifTool Main table is
  consulted under the feature. Further ProcessBinaryData sub-tables are decoded
  with per-table element size — MyColors and ContrastInfo (int16), TimeInfo and
  AspectInfo (int32), and FaceDetect3. ImageUniqueID (16-byte hex) and DateStampMode
  decode too. Validated against real camera samples: IXUS 400 31%→99%, PowerShot S40
  →99%, edited HDR files (AFInfo3, newer body) →100%, all with exact value matches.

• EXIF / Interop / Canon Main tag names aligned to ExifTool under
  exiftool-tables for the handful of divergences (DateTime→ModifyDate,
  DateTimeDigitized→CreateDate, PhotographicSensitivity→ISO,
  PixelX/YDimension→ExifImage{Width,Height},
  Interoperability{Index,Version}→Interop{Index,Version},
  CanonOwnerName→OwnerName, CanonImageNumber→FileNumber,
  CanonThumbnailValidArea→ThumbnailImageValidArea). Lens fields are
  deliberately not remapped (the lens-formatting post-pass keys off the names).
  With all of the above, clean Canon samples reach 99% tag parity with exiftool.

Fixed

• Maker-note parsing repaired for several vendors (BSD core, all builds). The
  Fujifilm maker note read its IFD offset from the wrong byte (12 instead of 8) and
  mis-resolved value offsets — it now parses against the full block from the correct
  offset. Nikon Type 2/3 (embedded TIFF header at offset 10) is detected so COOLPIX
  bodies parse. Header-less big-endian Konica-Minolta IFDs are now byte-order
  detected. Under exiftool-tables, Nikon names are aligned to ExifTool. Validated
  against real samples: Fujifilm 68%→98-100%, Nikon COOLPIX 63%→95%, Konica-Minolta
  76%→97%.
• Olympus "type-2" maker notes (OLYMPUS\0II…) are now parsed: the main IFD plus
  its nested Equipment / CameraSettings / RawDevelopment / ImageProcessing / FocusInfo
  sub-IFDs (decoded via generated ExifTool tables under the feature).
• Nikon AFInfo (0x0088) / FlashInfo (0x00A8) decoded on COOLPIX bodies.
• UNDEFINED (type 7) values are read as a single trimmed blob instead of a string
  repeated from every byte offset (fixes e.g. Panasonic InternalSerialNumber).
• Canon maker-note Main tag ids corrected (BSD core, all builds): 0x000C is
  the serial number (was mislabelled CanonModelID), 0x0010 is the model id
  (was CanonThumbnailValidArea), 0x0013 is the thumbnail valid area (was
  missing), 0x0015 is the serial-number format, 0x001C is DateStampMode (was
  CanonAFInfo), and 0x0028 is ImageUniqueID rendered as 16-byte hex (was
  CanonCRWParam). The model-name lookup now applies to 0x0010 instead of the
  serial number at 0x000C. Verified against exiftool's raw values.

Changed

• Dropped the creatingLibrary header from JSON and XML output. The block
  (name/version/url) only identified the producing tool and carried nothing
  about the parsed file, so it is no longer emitted. JSON now opens directly at
  "media"; XML goes straight from the <MediaInfo> header to <media>. This is
  a deliberate divergence from mediainfo's wire format — consumers that validate
  against the published mediainfo schema or read creatingLibrary.version will see
  a missing key. revelo-diff strips the oracle's creatingLibrary line before
  comparing, so the diff harness stays focused on per-stream differences.

revelo v0.3.2

Fixed

• Panic-safety on malformed/truncated input: guard MP4 avcC/hvcC parsing
  against truncated boxes; correct the SCTE-35 splice-header byte offsets and a
  parse_splice_insert off-by-one; checked/saturating size arithmetic in
  AVI/MKV/MP4/MXF (safe on 32-bit wasm32).

revelo v0.3.1

Fixed

• JSON output now escapes control characters (U+0000–U+001F) as \u00xx
  instead of emitting raw bytes, producing valid JSON when binary metadata is
  present.
• JFIFVersion extracted from the JPEG APP0 segment (e.g. 1.01).

revelo v0.3.0

Added

• EXIF rewrite — full IFD chain traversal (IFD0, ExifIFD, GPS IFD, InteropIFD,
  IFD1), 170+ tag names including EXIF, GPS, and maker-note tags parsed via IFD
  iteration; GPS coordinates computed as decimal degrees (GPSLatitudeRef /
  GPSLongitudeRef)
• Lens specification formatting — LensSpec field computed from
  LensModel, MaxApertureAtMinFocal, MaxApertureAtMaxFocal, MinFocalLength,
  MaxFocalLength, and LensType; LensType hex formatting
• IPTC IIM enhanced — full 0x1C-delimited IIM dataset parsing, cross-reference
  with IPTC-NAA tag keys via parse_iim_buf for datasets > 0x80 bytes on 0x83BB
  records
• XMP enhanced — additional EXIF field name mappings (ExifIFD, GPS, IIM
  cross-references) and XMP_xmpMM_* namespace tags
• MakerNote stub — parse_makernote infrastructure hook, returns () for now
