tbc-tools v3.2.1 release notes

Range: v3.2.0 → v3.2.1 (8 commits)

User-facing changes

• Improved chapter skip behavior in ld-analyse:

  • Start/End navigation now prioritize VBI chapter maps and user defined.
  • Falls back to user timeline markers when no chapter map exists.
  • Falls back again to ±10-frame navigation when neither is available.
  • Added press-and-hold repeated skip behavior for Start/End controls.

• Improved resilience in ld-chroma-decoder when metadata and source fields do not match:

  • Truncated/damaged source mismatches no longer abort processing.
  • Decoder now falls back to blank fields and logs warnings instead.

Decoder/vendor updates

• Added cc_decoder as a vendored submodule for ld-process-vbi:
• Submodule path: src/ld-process-vbi/vendor/cc_decoder
• Source: https://github.com/eshaz/cc_decoder.git

QA and regression coverage

• Added fresh-DB targeted decode regression checks:
• New CTest entries for NTSC/PAL CLV fresh-db decode paths.
• Extended scripts/test-decode-pretbc with fresh-db compare logic for metadata tables.
• Added missing test fixture metadata:
• test-data/ntsc/ve-snw-cut.tbc.json
• Added ld-chroma-decoder regression test target for source-field mismatch scenarios.

Release/build maintenance

• Windows vcpkg cache refresh commits (x64 and arm64 cache artifacts).
• Release prep bumped project version to 3.2.1 in:
• flake.nix
• vcpkg.json
