using token-buffer (that is: slightly more memory. O(output_size)) This change is ON by default. To return to previous behaviour, use 'cwebp -low_memory' or set config.low_memory to true. Side-effect of this new mode: it forces 1 partition only (which was default anyway), and makes some statistics about the bitstream no longer available. cwebp will no longer report 'intra4-coeffs', etc. This mode also doesn't work (yet) with multi-pass, and -low_memory is currently forced for multi-pass. also: reversed the flag: USE_TOKEN_BUFFER -> DISABLE_TOKEN_BUFFER also: fixed the kAverageBytesPerMB estimate Change-Id: I4ea80382038d6df4309663e0cb7bd88d9bca9cf1

- next version:
|
|
* WebPINewRGB/WebPINewYUVA accept being passed a NULL output buffer
|
|
and will perform auto-allocation.
|
|
* default filter option is now '-strong -f 60'
|
|
* encoding speed-up for lossy methods 3 to 6
|
|
|
|
- 10/30/12: version 0.2.1
|
|
* Various security related fixes
|
|
* cwebp.exe: fix import errors on Windows XP
|
|
* enable DLL builds for mingw targets
|
|
|
|
- 8/3/12: version 0.2.0
|
|
* Add support for ARGB -> YUVA conversion for lossless decoder
|
|
New functions: WebPINewYUVA, WebPIDecGetYUVA
|
|
* Add stats for lossless and alpha encoding
|
|
* Security related hardening: allocation and size checks
|
|
* Add PAM output support to dwebp
|
|
|
|
- 7/19/12: version 0.1.99
|
|
* This is a pre-release of 0.2.0, not an rc to allow for further
|
|
incompatible changes based on user feedback.
|
|
* Alpha channel encode/decode support.
|
|
* Lossless encoder/decoder.
|
|
* Add TIFF input support to cwebp.
|
|
Incompatible changes:
|
|
* The encode ABI has been modified to support alpha encoding.
|
|
* Deprecated function WebPINew() has been removed.
|
|
* Decode function signatures have changed to consistently use size_t over
|
|
int/uint32_t.
|
|
* decode_vp8.h is no longer installed system-wide.
|
|
* cwebp will encode the alpha channel if present.
|
|
|
