Pascal Massimino	815652de03	enable dc error-diffusion always ... for q<=98, we always enable error diffusion. + reduce storage 2x by using int8_t + make the error diffusion more robust BUG=webp:340,308 Change-Id: I0608df839ff7b64d6843005a0f81d2577143af9e	2017-12-27 20:11:57 +00:00
Pascal Massimino	96bf07c560	use DC error diffusion for U/V at low-quality ... This fixes some color smearing due to heavy quantization. This is only enabled for q <= 30 (cf ERROR_DIFFUSION_QUALITY) Change-Id: I07e83a4d38461357a32c9e214f7eadc6db73baa9	2017-12-11 06:37:40 -08:00

James Zern	668e1dd44f	src/{dec,enc,utils}: give filenames a unique suffix ... this avoids duplicates between these trees and dsp/, e.g., enc/tree.c, dec/tree.c, making pulling the whole library source tree into one target possible BUG=webp:279 Change-Id: I060a614833c7c24ddd37bf641702ae6a5eef1775	2017-01-19 19:09:48 -08:00
