Local modifications:
- Rewrite Android.mk to remove duplicate definitions and set module name
in a consistent way with other external libraries
-- Move public headers from src/webp to include/webp, so path to headers
+- Copy public headers from src/webp to include/webp, so path to headers
may be appended into CFLAGS without risk for other private headers
(e.g. bits.h) to leak into
-- Sync-patch with libwebp ver 0.1.2
-- Removed Build files necessary for building via autoconf/automake tools
+- Removed build files necessary for building via autoconf/automake tools
These files are not required to build via Android.mk
- - Makefile.am Makefile.vc Makefile.in
- - config.h.in configure config.guess config.sub configure.ac
- - autogen.sh install-sh missing depcomp ltmain.sh aclocal.m4
-- Added WebP Encoder (ver 0.1.2) as well
- - Removed some more unused Makefile.am & Makefile.in
- - Added Android.mk to encoder & decoder code levels.
-- Synced the WebP Code (Encoder/Decoder) with the head change#Ia53f845b
- - Added three color-spaces viz ARGB_8888, RGBA_4444, RGB_565
- supported by Android.
-- Fixed the Endian'ness bug for Color-Configs (RGB_565 & ARGB_4444).
- The fix is similar to jpeglib handling for JCS_RGB_565 & JCS_RGBA_8888
- color configs. Added the code under "ANDROID_WEBP_RGB" flag.
-- Sync-patch with libwebp ver 0.2.0-rc1 (head change#Ia5475247).
-- Updated WebP with head change#I3da2063b
-- Updated WebP with head change#I9e5ae737
- - 16bit swapping of RGB565 / RGB4444 colorspace. Added compile-time flag
- WEBP_SWAP_16BIT_CSP to support byte-swap (required for skia data type for
- 16bit values) output for these colorspaces.
- - Added ARM/NEON code for decoder/encoder modules.
- - Speedup in WebP compression (method 3 and above).
- - Added multi-threaded alpha encoding for lossy compression.
- - Updated WebP with head change#I9e5ae737
-- Sync-patch with libwebp ver 0.3.1 (head change#Idea3464b).
- - Add incremental decoding support for images containing ALPH and ICCP chunks.
-- Updated WebP with patches required for Animation
- (#I737451d7f, #Ia300385a & #I9566a8e2).
-- Fix memleak in WebPIDelete() (change#Id4faef1b).
-- Sync-patch with libwebp ver 0.4.0-rc1 (change#I22be12d8).
-- Bugfix for incremental decode of lossy-alpha (change#I716ce082)
-- Sync-patch with libwebp ver 0.4.1-rc1 (change#I5346984d2).
- - NEON assembly optimizations:
- - ~25% faster lossy decode / encode (-m 4)
- - ~10% faster lossless decode
- - ~5-10% faster lossless encode (-m 3/4)
- - Arch64 (arm64) & MIPS support/optimizations.
-- Sync-patch with libwebp ver 0.4.2 (change#I32a22786f).
- - Cherry-picked Alpha-decoding bug.
+- Added a local copy of cpu-features.[hc] to src/dsp
+- Removed WEBP_ANDROID_NEON check in dsp.h to avoid breaking non-NEON builds
+ where the flags in Android.mk are not set correctly currently.
-The Android.mk file creates WebP Decoder and Encoder static libraries which
-can be added to any application by Adding to LOCAL_STATIC_LIBRARIES
