- Update to version 1.8.1:
* This release collects incremental improvements to many aspects
of the library.
* Upgrading:
- VP8E_SET_CPUUSED now accepts values up to 9 for vp9.
- VPX_CTRL_VP9E_SET_MAX_INTER_BITRATE_PCT had a spelling fix
(was VP8E).
- The --sdk-path option has been removed. If you were using it
to build for Android please read build/make/Android.mk for
alternatives.
- All PPC optimizations have been disabled:
https://bugs.chromium.org/p/webm/issues/detail?id=1522.
* Enhancements: Various changes to improve encoder rate control,
quality and speed for practically every use case.
* Bug fixes: vp9-rtc: Fix color artifacts for speed >= 8.

This release improves upon the VP9 encoder and speeds up the encoding and
decoding processes.
- 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.
