1 URL: http://review.webmproject.org/gitweb?p=libwebp.git 2 Version: 43/1443/1 3 License: Google BSD like 4 5 Local modifications: 6 - Rewrite Android.mk to remove duplicate definitions and set module name 7 in a consistent way with other external libraries 8 - Move public headers from src/webp to include/webp, so path to headers 9 may be appended into CFLAGS without risk for other private headers 10 (e.g. bits.h) to leak into 11 - Sync-patch with libwebp ver 0.1.2 12 - Removed Build files necessary for building via autoconf/automake tools 13 These files are not required to build via Android.mk 14 - Makefile.am Makefile.vc Makefile.in 15 - config.h.in configure config.guess config.sub configure.ac 16 - autogen.sh install-sh missing depcomp ltmain.sh aclocal.m4 17 - Added WebP Encoder (ver 0.1.2) as well 18 - Removed some more unused Makefile.am & Makefile.in 19 - Added Android.mk to encoder & decoder code levels. 20 - Synced the WebP Code (Encoder/Decoder) with the head change#Ia53f845b 21 - Added three color-spaces viz ARGB_8888, RGBA_4444, RGB_565 22 supported by Android. 23 - Fixed the Endian'ness bug for Color-Configs (RGB_565 & ARGB_4444). 24 The fix is similar to jpeglib handling for JCS_RGB_565 & JCS_RGBA_8888 25 color configs. Added the code under "ANDROID_WEBP_RGB" flag. 26 - Sync-patch with libwebp ver 0.2.0-rc1 (head change#Ia5475247). 27 - Updated WebP with head change#I3da2063b 28 - Updated WebP with head change#I9e5ae737 29 - 16bit swapping of RGB565 / RGB4444 colorspace. Added compile-time flag 30 WEBP_SWAP_16BIT_CSP to support byte-swap (required for skia data type for 31 16bit values) output for these colorspaces. 32 - Added ARM/NEON code for decoder/encoder modules. 33 - Speedup in WebP compression (method 3 and above). 34 - Added multi-threaded alpha encoding for lossy compression. 35 - Updated WebP with head change#I9e5ae737 36 - Sync-patch with libwebp ver 0.3.1 (head change#Idea3464b). 37 - Add incremental decoding support for images containing ALPH and ICCP chunks. 38 - Updated WebP with patches required for Animation 39 (#I737451d7f, #Ia300385a & #I9566a8e2). 40 - Fix memleak in WebPIDelete() (change#Id4faef1b). 41 - Sync-patch with libwebp ver 0.4.0-rc1 (change#I22be12d8). 42 - Bugfix for incremental decode of lossy-alpha (change#I716ce082) 43 - Sync-patch with libwebp ver 0.4.1-rc1 (change#I5346984d2). 44 - NEON assembly optimizations: 45 - ~25% faster lossy decode / encode (-m 4) 46 - ~10% faster lossless decode 47 - ~5-10% faster lossless encode (-m 3/4) 48 - Arch64 (arm64) & MIPS support/optimizations. 49 50 The Android.mk file creates WebP Decoder and Encoder static libraries which 51 can be added to any application by Adding to LOCAL_STATIC_LIBRARIES 52 libwebp-decode libwebp-encode: 53 54 LOCAL_STATIC_LIBRARIES += libwebp-decode libwebp-encode 55 56
