[1.2.0] - 2026-04-21

Added

  • Added MP3 decode component Mp3Decoder to produce PCM signed 16-bit little-endian output via Java Sound runtime SPI.
  • Added optional experimental pure-Java MP3 decode backend PureJavaMp3Decoder with MP3 frame-based PCM timeline synthesis outputting PCM S16LE.
  • Added MP3 conversion route handler Mp3PcmWavConverter for mp3 -> pcm and mp3 -> wav workflows.
  • Added conversion regression coverage in Mp3PcmWavConverterTest for both target formats with runtime-safe assertions.

Changed

  • Extended MP3 conversion preset handling in Mp3PcmWavConverter with decoder token selection: decoder=javasound (default), decoder=pure-java, and alias decoder=layer3, including explicit unsupported-token errors.
  • Updated audio conversion route wiring in DefaultConversionHub to prioritize MP3 decode routes (mp3 -> pcm, mp3 -> wav) before generic Java Sound audio transcoding.
  • Hardened FLAC parsing in FlacParser with strict STREAMINFO block length validation, reserved metadata-type checks in Vorbis read path, ID3v2-leading FLAC detection, and explicit malformed Vorbis-comment errors.
  • Hardened WebP probing in WebpParser with null-safe RIFF checks, declared-size bounds validation, chunk-payload bounds validation, VP8 key-frame validation, and clearer variant-specific error messages.
  • Clarified runtime requirements in WebpCodec for ImageIO WebP reader/writer SPI availability.
  • Hardened BMP probing in BmpParser with null-safe signature checks and explicit DIB header truncation validation (14 + dibHeaderSize <= file length).
  • Added public BMP probe entrypoint BmpCodec.probe() to expose lightweight header probing through codec API.
  • Hardened PNG probing in PngParser with null-safe signature checks and strict PNG-spec bitDepth/colorType combination validation.
  • Added public PNG probe entrypoint PngCodec.probe() to expose lightweight header probing through codec API.
  • Hardened JPEG signature sniffing in JpegParser.isLikelyJpeg() to accept SOI-based detection (FF D8) with null-safe handling.
  • Added public JPEG probe entrypoint JpegCodec.probe() to expose header-based JPEG probing through codec API.
  • Hardened TIFF signature sniffing in TiffParser.isLikelyTiff() with null-safe handling, and documented that probe-level BitsPerSample reports the first component value.
  • Added public TIFF probe entrypoint TiffCodec.probe() and clarified runtime ImageIO TIFF plugin requirements in codec documentation.
  • Hardened HEIF parsing in HeifParser with null-safe signature checks, pixi FullBox version validation (version == 0), and bounded recursive box traversal depth.
  • Added public HEIF probe entrypoint HeifCodec.probe(), clarified runtime ImageIO HEIF/AVIF plugin requirements, and corrected AVIF format mapping to avif during encode target normalization.
  • Bumped artifact version to 1.2.0 in pom.xml.
