Attribution

libchromadec extracts and consolidates work originally authored across several upstream projects. This page lists the primary contributors whose work is preserved here. The repo's git log and .mailmap are the authoritative source; this page summarises.

Original tools/ld-chroma-decoder and tools/library code

The git history extracted from ld-decode via git filter-repo preserves the authorship of every commit that touched tools/ld-chroma-decoder/ or tools/library/ up to commit f39e59e18 (the last commit before the tools/ directory was removed from ld-decode). Use git shortlog -sne to enumerate.

Particular contributors visible in that history (non-exhaustive):

• Simon Inns (simoninns): original ld-chroma-decoder and TBC library author; ongoing maintainership of decode-orc / encode-orc / CVBS spec
• Chad Page: original ld-decode author, NTSC comb filter work
• Adam Sampson: Transform-PAL implementation, decoder pool, output writer
• Phillip Blucas: PALcolour and PAL-M support
• Dani Funker: chroma weight, NTSC 3D adaptive threshold options
• many more: run git log --follow on any ported source (say src/decoders/palcolour/palcolour.cpp) to walk back through the extracted history to its original authors

nnTransform3D models and original harnesses

• asdfqazsnbb: original author of the nnTransform3D models and both v1 and v2 harnesses. The models were originally distributed through Discord chats before v2 was open-sourced on GitHub.
• harrypm: first to bring the nnTransform3D code into a public repo (the tbc-tools fork of ld-decode-tools), where it lived as patches to src/ld-chroma-decoder/comb.{h,cpp}. The CUDA side of that integration (nnTransform3D_kernel.cu and its comb.cpp wiring) contributed by asdfqazsnbb directly.

ldzeug2 models and harnesses

• jsaowji: author of the ldzeug2 project (Python/VapourSynth) and the underlying color_cnn / luma_sep / luma_sep_frame CNN models.
• The C++ integration in the vapoursynth-analog project (src/ldzeug_decoders.{h,cpp}) was contributed by its maintainers building on jsaowji's reference implementation.

CVBS file format specification

• Simon Inns and the contributors to the cvbs-file-format-specification project: define the file format this library reads alongside the .tbc format.
