v35

• Deprecated old option parser
• Major improvements on dumps and assert-ids (av1-isobmff and av1-avif)
• Add J2K #75
• Add 'iinf' ordering check #86 before updating the ISOBMFF specification to make it a normative statement
• Clarify HEIF file suffixes #87
• Fix AV1-ISOBMFF text mistmatches #85
• iloc: put construction_method at zero when not parsed (box version = 0) #82
• isobmff: improve chunk support
• isobmff: fix sample offset computation
• av1 configs: fix consistency issues
• heif: ispe checks only apply to Image Items #74

v34

General:

• Better use of out->covered()
• Tests: use automatic offset computation when applicable
• Add uncv, unci sample entries
• list specs and rules as json

AV1-ISOBMFF (new!):

• Add spec with version 1.2.0

AV1 HDR10+:

• Finalize

AVIF:

• Improve some data offset computation

ISOBMFF:

• More tests
• Add co64 support

v33

General:

• move formatting from uncrustify to clang-format
• add option parser - fix #48
• fix MacOS build
• list available specs when a wrong spec name is submitted
• tests: do not expand CXX unless set
• JSON report: add unchecked rule list in json report - see #53
• Python script: address issue #52

ISOBMFF:

• major brand should be repeated in compatible_brands

HEIF:

• heif: fix early exit in test on ispe coming before transform properti…

AV1/

• add input_file on .obu inputs - fix #54

HDR10+:

• fix typo HR10+ -> HDR10+ - fix #63

v32

AVIF:

• Fix av1AlphaTrackFirstOffset computation thanks to @vigneshvg

AV1 HDR 10+:

• Improve TU processing
• Added scripts/hdr10plusrules.py thanks to @podborski . This scripts retrieves the 'assert-ids' (see below) from the AV1-HDR10+ specification.

Misc:

• Add possibility to identify rules with 'assert-ids'. 'assert-ids' are a way to link the specification normative statements with the rules implemented in CW.
• Add possibility to know if an input sample actually exercized a rule with out->covered(). Some real-life samples used to pass without exercizing the feature they were meant to implement.
• Add JSON report.

v31

AV1 HDR 10+:

• Support ISOBMFF inputs
• Improve error messages

Misc:

• Lower memory usage to avoir WebAssembly runtime errors on bug files

v30

Add HDR10+ bitstream tests:

• OBU bitstream only (no ISOBMFF Section 3 yet)

• Support 'iloc' version=0 (no construction_method )

ISOBMFF:

• Split 'hdlr' tests
• Fix box size 0 parsing

General:

• Created subfolders as there were more source files

v29

AVIF:

• Check brands

• Additional grid checks
• 'mif1'/'msf1' checks
• Exif/xmp medadata checks

ISOBMFF:

• More box checks (box versions, arity and parents)
• 'hdlr' checks
• More data offset checks
• Improve derivation chains error/cycle detections and reporting
• Parse 'clap' box to improve test vectors reporting

Global:

• Updated readme
• Updated formatter
• Improved overall coverage by adding missing tests
• Effort on robustness

v28
