a WebP encoder converts PNG & JPEG to WebP This is an experimental early version, with lot of room of later optimizations in both speed and quality. Compile with the usual `./configure && make` Command line example is examples/cwebp Usage: cwebp [options] -q quality input.png -o output.webp where 'quality' is between 0 (poor) to 100 (very good). Typical value is around 80. More encoding options with 'cwebp -longhelp' Change-Id: I577a94f6f622a0c44bdfa9daf1086ace89d45539

add Advanced Decoding Interface You can now use WebPDecBuffer, WebPBitstreamFeatures and WebPDecoderOptions to have better control over the decoding process (and the speed/quality tradeoff). WebPDecoderOptions allow to: - turn fancy upsampler on/off - turn in-loop filter on/off - perform on-the-fly cropping - perform on the-fly rescale (and more to come. Not all features are implemented yet). On-the-fly cropping and scaling allow to save quite some memory (as the decoding operation will now scale with the output's size, not the input's one). It saves some CPU too (since for instance, in-loop filtering is partially turned off where it doesn't matter, and some YUV->RGB conversion operations are ommitted too). The scaler uses summed area, so is mainly meant to be used for downscaling (like: for generating thumbnails or previews). Incremental decoding works with these new options. More doc to come soon. dwebp is now using the new decoding interface, with the new flags: -nofancy -nofilter -crop top left width height -scale width height Change-Id: I08baf2fa291941686f4ef70a9cc2e4137874e85e

create a separate libwebpdsp under src/dsp Gathers all DSP-related function (and SSE2 implementations). Clean-up some unwanted symbolic dependencies so that webp_encode, webp_decode and webp_dsp are truly independent libraries. + opportunistic clean-up: * remove unneeded VP8DspInitTables(), now integrated in VP8DspInit() * make consistent use of VP8GetCPUInfo() in the various DspInit() funcs * change OUT macro to DST

multi-thread decoding: ~25-30% faster To be enabled with the flag WEBP_USE_THREAD. For now it's only available on unix (pthread), when using Makefile.unix Will be switched on more generally later. In-loop filtering and output (=rescaling/yuv->rgb conversion) is done in parallel to bitstream decoding, lagging 1 row behind. Example: examples/dwebp bryce.webp -v Time to decode picture: 0.680s examples/dwebp bryce.webp -v -mt Time to decode picture: 0.515s Change-Id: Ic30a897423137a3bdace9c4e30465ef758fe53f2
