- 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:

- disable vsx on ppc64le to fix build failure
- update to version 1.8.0
This release focused on encoding performance for realtime and VOD use cases.
- Upgrading:
This adds and improves several vp9 controls. Most are related to SVC:
VP9E_SET_SVC_FRAME_DROP_LAYER:
- Frame dropping in SVC.
VP9E_SET_SVC_INTER_LAYER_PRED:
- Inter-layer prediction in SVC.
VP9E_SET_SVC_GF_TEMPORAL_REF:
- Enable long term temporal reference in SVC.
VP9E_SET_SVC_REF_FRAME_CONFIG/VP9E_GET_SVC_REF_FRAME_CONFIG:
- Extend and improve this control for better flexibility in setting SVC
pattern dynamically.
VP9E_SET_POSTENCODE_DROP:
- Allow for post-encode frame dropping (applies to non-SVC too).
VP9E_SET_SVC_SPATIAL_LAYER_SYNC:
- Enable spatial layer sync frames.
VP9E_SET_SVC_LAYER_ID:
- Extend api to specify temporal id for each spatial layers.
VP9E_SET_ROI_MAP:
- Extend Region of Interest functionality to VP9.
- Enhancements:
2 pass vp9 encoding has improved substantially. When using --auto-alt-ref=6,
we see approximately 8% for VBR and 10% for CQ. When using --auto-alt-ref=1,
the gains are approximately 4% for VBR and 5% for CQ.
For real-time encoding, speed 7 has improved by ~5-10%. Encodes targeted at
screen sharing have improved when the content changes significantly (slide
sharing) or scrolls. There is a new speed 9 setting for mobile devices which

- update to version 1.7.0
This release focused on high bit depth performance (10/12 bit) and vp9
encoding improvements.
- Upgrading:
This release is ABI incompatible due to new vp9 encoder features.
Frame parallel decoding for vp9 has been removed.
- Enhancements:
vp9 encoding supports additional threads with --row-mt. This can be greater
than the number of tiles.
Two new vp9 encoder options have been added:
--corpus-complexity
--tune-content=film
Additional tooling for respecting the vp9 "level" profiles has been added.
- Bug fixes:
A variety of fuzzing issues.
vp8 threading fix for ARM.
Codec control VP9_SET_SKIP_LOOP_FILTER fixed.
Reject invalid multi resolution configurations.
- drop obsolete CVE-2017-13194.patch
- switch to git service since no tar ball at the old place anymore
- so name increase to 5
- use gnu99 for ppc

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.
