richgel999	9529bdbff8	Still a WIP - needs more testing (especially when video is disabled, which hasn't been tested on this branch yet): ... - Adding conditional replenishment (CR) support to the system, so blocks which don't change their selectors or endpoints from the last frame don't need to be decoded. This can greatly increase the compression ratio on many video sequences. - Updating help text. - Adding support for slices to be marked as i-frames - Updating transcoder to support CR	2019-05-18 17:54:52 -07:00
Rich Geldreich	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
Rich Geldreich	d699c819f7	Moving g_hamming_dist[] array from transcoder to encoder (it's never used by the transcoder). ... Adding remarks to basisu_file_header.h	2019-05-08 20:01:35 -07:00
Rich Geldreich	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.	2019-05-02 16:09:11 -07:00
