7d784c7288 Correcting the copyright date, as all of the Basis Universal code was written during/after April '19. 2019-06-09 18:29:41 -07:00

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.

78e22234bd More transcoder fixes found during fuzz testing (I disabled all header/data CRC checking by setting BASISU_NO_HEADER_OR_DATA_CRC16_CHECKS to 1). 2019-05-09 14:43:13 -07:00

d699c819f7 Moving g_hamming_dist[] array from transcoder to encoder (it's never used by the transcoder).
Adding remarks to basisu_file_header.h

33996b1a5f Important: Changing the Basis file version, so any existing files will need to be recompressed!
Adding new fields to the basis header: texture type and framerate. Texture type may be 2D, 2D array, video, volume, or cubemap array. The compressor makes sure that anything other than pure 2D follows certain constraints (cubemap arrays must have a multiple of 6 input images, videos/texture array images all must have the same resolution/# of mipmaps, etc.)
When unpacking cubemaps, the -unpack command now writes cubemap .KTX files which various tools like PVRTexTool support.
