Newlib static and shared object port of libVPX, a freely available and open-source video codec. Multithreading is not enabled in this port. Changes (general): 2017-01-09 v1.6.1 "Long Tailed Duck" This release improves upon the VP9 encoder and speeds up the encoding and decoding processes. - Upgrading: This release is ABI compatible with 1.6.0. - Enhancements: Faster VP9 encoding and decoding. High bit depth builds now provide similar speed for 8 bit encode and decode for x86 targets. Other platforms and higher bit depth improvements are in progress. - Bug Fixes: A variety of fuzzing issues. 2016-07-20 v1.6.0 "Khaki Campbell Duck" This release improves upon the VP9 encoder and speeds up the encoding and decoding processes. - Upgrading: This release is ABI incompatible with 1.5.0 due to a new 'color_range' enum in vpx_image and some minor changes to the VP8_COMP structure. The default key frame interval for VP9 has changed from 128 to 9999. - Enhancement: A core focus has been performance for low end Intel processors. SSSE3 instructions such as 'pshufb' have been avoided and instructions have been reordered to better accommodate the more constrained pipelines. As a result, devices based on Celeron processors have seen substantial decoding improvements. From Indian Runner Duck to Javan Whistling Duck, decoding speed improved between 10 and 30%. Between Javan Whistling Duck and Khaki Campbell Duck, it improved another 10 to 15%. While Celeron benefited most, Core-i5 also improved 5% and 10% between the respective releases. Realtime performance for WebRTC for both speed and quality has received a lot of attention. - Bug Fixes: A number of fuzzing issues, found variously by Mozilla, Chromium and others, have been fixed and we strongly recommend updating.
