[1.1.1] - 2026-03-14

Fixed

  • Improved MP3 duration estimation in Mp3Parser.estimateDurationMillis() to prioritize Xing/VBRI frame-count metadata before scanned sample totals.
  • Excluded trailing ID3v1 tag bytes from MP3 audio scan range in Mp3Parser, reducing bitrate drift when footer tags are present.
  • Added clearer non-Layer III error handling in Mp3Parser.parse() for MPEG Layer I/II inputs.
  • Strengthened OGG logical-stream parsing in OggParser with per-stream page-sequence validation and serial-scoped metrics for multiplexed files.
  • Refined Vorbis bitrate-mode classification in OggParser.detectVorbisBitrateMode() to infer from observed bitrate variation instead of coarse nominal/page-count heuristics.
  • Replaced broad OGG payload string scanning with structured Vorbis/Opus comment-header parsing in OggParser, and fixed sequence tracking to use long to avoid overflow.
  • Updated WavParser to read/validate audioFormat from fmt and reject unsupported compressed WAV formats instead of silently computing incorrect duration.
  • Added RF64-aware WAV parsing in WavParser, including unsigned chunk-size handling and data size sentinel (0xFFFFFFFF) resolution via ds64.
  • Updated FlacParser to reject reserved metadata block type 127 per FLAC spec.
  • Updated FlacParser bitrate estimation to use encoded audio payload region after metadata blocks (instead of whole file bytes), reducing artwork/metadata inflation.
  • Updated AiffParser to validate AIFC COMM compression type and reject unsupported compressed variants.

Added

  • Added MP3 parser regression tests for Xing-priority duration, trailing ID3v1 handling, and unsupported Layer I/II diagnostics in Mp3ParserTest.
  • Added OGG parser tests for Vorbis CBR/VBR mode inference, broken page-sequence detection, and multiplexed-stream metric isolation in OggParserTest.
  • Added WAV parser tests for unsupported compressed format rejection and RF64 ds64/data sentinel handling in WavParserTest.
  • Added FLAC parser tests for reserved block type rejection and metadata-heavy bitrate estimation behavior in FlacParserTest.
  • Added explicit decode-only intent comment in FlacCodec.
  • Added AIFF parser tests for supported AIFC NONE and unsupported compression-type rejection in AiffParserTest.
  • Added explicit decode-only intent comment in AiffCodec.

Verified

  • Confirmed MP3 parser updates with mvn -Dtest=Mp3ParserTest test.
  • Confirmed OGG parser updates with mvn -Dtest=OggParserTest test.
  • Confirmed WAV parser updates with mvn -Dtest=WavParserTest test.
  • Confirmed FLAC parser updates with mvn -Dtest=FlacParserTest test.
  • Confirmed AIFF parser updates with mvn -Dtest=AiffParserTest test.

[1.1.0] - 2026-03-13

Changed

  • Migrated repository ownership and project references to CodecMediaLib/codecmedia-java.
  • Updated SCM/issue/CI metadata in pom.xml.
  • Updated organization metadata in pom.xml to CodecMediaLib.

Notes

  • This 1.1.0 release is a transition baseline and prepares for larger updates planned in the 1.1.* series.

[1.0.4] - 2026-03-05

Added

  • Added richer MOV probe fields in MovProbeInfo: videoBitrateKbps, audioBitrateKbps, bitDepth, and displayAspectRatio.
  • Added richer MP4 probe fields in Mp4ProbeInfo: codec/audio stream details, frame rate, bitrate fields, bit depth, and display aspect ratio.
  • Added richer WebM probe fields in WebmProbeInfo: per-track bitrate fields and display aspect ratio.
  • Added real fixture coverage in CodecMediaFacadeTest for probe/strict-validate using files under src/test/resources/example.
  • Added round-trip conversion test class CodecMediaRoundTripConversionTest to validate same-extension convert->convert flows across all real example extensions (mp3, mp4, png, webm).

Changed

  • Enhanced MOV parsing in MovParser with deeper BMFF track metadata extraction (hdlr, mdhd, stsd, btrt, stsz) and fallback bitrate estimation.
  • Enhanced MP4 parsing in Mp4Parser to extract video/audio codec, sample rate, channels, frame rate, bit depth, bitrate, and aspect ratio.
  • Enhanced WebM parsing in WebmParser to extract track bitrate when present and compute fallback bitrate/aspect ratio values.
  • Updated stream/tag mapping in StubCodecMediaEngine so MOV/MP4/WebM probe results now expose richer stream bitrate and container tags (displayAspectRatio, bitDepth, videoBitrateKbps, audioBitrateKbps).

Verified

  • Confirmed test stability after video parser improvements with mvn test.
  • Confirmed real-fixture conversion regression path with mvn -Dtest=CodecMediaRoundTripConversionTest test.
