57ca9acadd Fixed undefined behavior in BASISU_OFFSETOF 
The original implementation was dereferencing a nullptr which is an undefined behavior according to the C++ spec. It was triggering some automatic errors during our sanitizer tests (asan with nullptr check).

The fix replaces the offset with standard implementation of offsetof that uses compiler built in instructions when available (avoiding the undefined behavior).

With the default Xcode 11 settings, these non-functional changes remove warnings when building for iOS and Mac, notably:

Possible misuse of comma operator here

176df98c3e Don't require the huge BC7m6 tables if this format is disabled. 
The 1.3 MB file might be considered excessive when bundling the
transcoder sources in another project, don't require it to be present
when not needed.

01d391cc2a PVRTC1 apparently always use wrap addressing when fetching the adjacent block colors (even when clamp texture addressing is being used), so we don't need the wrap vs. clamp option anymore. It's always wrap and that's that. 2019-09-29 19:34:00 -07:00

54304fa014 - Adding PVRTC2 RGB/RGBA and ETC2 EAC R11 and RG11 
- Renaming -no_auto_global_sel_pal to -auto_global_sel_pal, disabling global selector palette usage by default to speed up compression on small images
- Renaming texture format enums
- Fixing uninitialized memory issue in front end - it wouldn't have affected the correctness of the output, or output quality
- Bumping command line tool up to v1.10

ab722fa2e1 - Adding support for skip blocks, i-frames and p-frames to the backend and transcoder, for texture video use. 
- For PVRTC1, we now memset() any extra blocks after the blocks we know will be transcoded into. This is done because in GL there is padding that occurs on textures smaller than 8x8.
- Removing all OpenMP usage and replacing it with a basis C++11 job system.
- Fixing TSVQ class so it can split very long "thin" clusters that before weren't being split. This improves endpoint quantization on videos and complex 2D textures.
- More frontend perf. optimizations.

Tested on OSX, Linux with gcc/clang, and Win using MSVC 2019.

f5d502912d Make codec options externally configurable and remove BC7 support 
This change makes it possible to exclude formats using compile time
options. BC7 is *never* exposed on the web and it has an absolutely huge
coding table which means we're just wasting space.

81464a6d6b Changing the ETC1S->BC4 and ETC1S->ETC2 EAC transcoders so they convert from the source red channel, not source green. Source red makes more sense when transcoding to BC4/BC5, especially when the source texture only has color slices. BC4 is red, and BC5 is red/green. This change makes no difference if the source texture slices are grayscale. 2019-05-10 22:04:48 -07:00

c7e14a97fa - Fixing minor block artifacts on pure 2 color B&W blocks when transcoding to BC1/BC7. This was caused by the ETC1S blocks using extreme ETC1S settings: codetable 7 (the one with the largest intensity deltas), using blocks with selectors that took up the full range (0-3), but the blocks only actually used the two outlier colors (0 and 3 only). The ETC1S->BC1/BC7 table based format conversion system doesn't realize that only the outlie colors were going to be used (i.e. not all 4 colors, just the outer 2), and so the quality of the transcoded block suffered because pure black could not be mapped. In BC7 mode, we now switch to pure BCT (block truncation coding) for any blocks with <= 2 unique colors, independent of their selectors. 
- Adding -csv_file option, to generate .csv files for mass benchmarking/testing
- Adding -no_ktx option, to avoid writing large .KTX files while unpacking
- Fixing printf() format issue when one of the -multifile options wasn't correct
