libwebp 0.4.1
- 7/24/14: version 0.4.1
This is a binary compatible release.
* AArch64 (arm64) & MIPS support/optimizations
* NEON assembly additions:
- ~25% faster lossy decode / encode (-m 4)
- ~10% faster lossless decode
- ~5-10% faster lossless encode (-m 3/4)
* dwebp/vwebp can read from stdin
* cwebp/gif2webp can write to stdout
* cwebp can read webp files; useful if storing sources as webp lossless
