Changelog

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.

[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.

[1.0.3] - 2026-03-05

Added

• Added OGG Opus identification/probing support alongside Vorbis in OggParser.
• Added AIFF/AIF/AIFC probing support with new parser/codec in AiffParser and AiffCodec.
• Added FLAC probing support with STREAMINFO parsing in FlacParser and FlacCodec.
• Added parser test coverage for MP3 VBR and mono channel-mode paths in Mp3ParserTest.
• Added parser test coverage for OGG Opus identification in OggParserTest.
• Added WAV parser synthetic profile tests (mono/stereo, sample-rate, bit-depth combinations) in WavParserTest.
• Added parser test coverage for AIFF probing in AiffParserTest.
• Added facade test coverage for .m4a probe/strict-validate flows in CodecMediaFacadeTest.
• Added parser/facade test coverage for .flac in FlacParserTest and CodecMediaFacadeTest.

Changed

• Improved probe routing in StubCodecMediaEngine to perform lightweight prefix-based type sniffing before full-file decode, reducing unnecessary full reads for unsupported/unknown inputs.
• Extended probe and strict validation routing in StubCodecMediaEngine to include AIFF/AIF/AIFC.
• Extended probe and strict validation routing in StubCodecMediaEngine to include FLAC.
• Expanded MP4 signature acceptance for M4A family brands in Mp4Parser.isLikelyMp4().
• Updated feature notes in README.md to reflect OGG Vorbis/Opus probing support and prefix-sniff probe behavior.

[1.0.2] - 2026-03-02

Added

• Added MOV parser/probe support via MovParser.
• Added WebM parser/probe support via WebmParser.
• Added MOV/WebM codec wrappers (MovCodec, WebmCodec) and probe info records.
• Added facade tests for MOV/WebM probe and strict validation in CodecMediaFacadeTest.

Changed

• Extended probing and strict validation routing in StubCodecMediaEngine to cover MOV and WebM.
• Updated project metadata URLs and branding references in pom.xml and README.md.

Fixed

• Fixed EBML element decoding in WebmParser so multi-byte element IDs (including DefaultDuration) are parsed with correct ID/size boundaries.
• Fixed MOV frame-rate extraction in MovParser to use mdhd track timescale when interpreting stts sample delta.

[1.0.1] - 2026-03-02

Added

• Initial public release with probing, validation, metadata sidecar persistence, extraction workflow, playback simulation, and conversion routing.
