5a1ae5d65d Fixing a very rare 1-bit overflow in ETC1S SSE optimized colorspace error calculations (which are 32-bit vs. the plain C++ code's 64-bit). Ultimately the output would still be correct and transcodable, but this could cause a compressor assertion check to fail. Found during compressor fuzz testing. 2025-11-18 17:27:51 -05:00

196db8cbe2 Merging as much of PR #408 as we safely can. 
PR 408's cmakelists.txt file has too many issues (OpenCL breaks on Windows/OSX) and changing our options to have the "BASISU_" prefix will break upstream builds.

100ace82d2 emcc warning fixes, fixing warnings in WASM cmakelists.txt files, changing ETC1S encoder to use std::map vs. std::unordered_map for hopefully more cross platform determinism 2025-06-24 17:22:05 -04:00

7a2094b807 Adding SAN option to CMakeLists.txt, to make it easier to use clang's address/undefined behavior sanitizer on codebase 
Fixing overflow issue on extreme colors in color_distance().
Explicitly disabling unaligned addressing in miniz and transcoder when UBSAN is enabled
Disabling a needless optimization in transcoder causing ubsan issues (that could have easily been worked around in a different way, but it was an unnecessary optimization to begin with)
Rebuild wasm builds

deeb5acb56 v1.16 release: OpenCL support, removing global selector palette code (it was unused/dead code), ETC1S encoding optimizations, -parallel command line option 2022-01-28 08:32:54 -05:00

7f0a00afe1 Adding KTX2 transcoding/encoding/decompression to PNG/KTX1 support to the transcoder, encoder, JavaScript wrappers. This is also adding Zstandard to the repo, which is optional. Set BASISD_SUPPORT_KTX2_ZSTD=0 when compiling the encoder/transcoder to disable it, or from cmake set KTX2_ZSTANDARD=FALSE. 2021-04-12 13:30:45 -04:00

2d4fe933b2 Basis Universal v1.13: 
- Optimized ETC1S encoder (3-4.5x faster)
- Added optional SSE 4.1 support to encoder
- Switched from std::vector to a custom vector in the encoder and transcoder
- Added CppSPMD (SSE only for now)
- UASTC RDO is now more effective, but the command line parameter controlling qualiy has changed (to "lambda")

85fa18ec94 Adding encoder WebAssembly support, encode_test sample 
Encoder is now a library in the "encoder" directory
JavaScript wrappers now expose the entire codec: encoder, transcoder, container independent transcoding, and .basis file information
