v1.8.1 "Orpington Duck"
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.
v1.8.0 "Northern Shoveler Duck"
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
is about 10-20% faster than speed 8.
- Bug fixes:
VP9 denoiser issue.
VP9 partition issue for 1080p.
VP9 rate control improvments.
Postprocessing Multi Frame Quality Enhancement (MFQE) issue.
VP8 multithread decoder issues.
A variety of fuzzing issues.
mode only, now. Set the target to generic-gnu for powerpc based ports on NetBSD
to allow libvpx to build and run, though without any targetted optimization.
Resolves build issue on NetBSD/macppc which failed at configure stage otherwise.
TenFourFox has patches to add support for Altivec acceleration, which could be
used to add support back again locally.

2017-01-04 v1.7.0 "Mandarin Duck"
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.
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.
Changelog:
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.
The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.
Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure. Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.
Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

Changelog:
2015-11-09 v1.5.0 "Javan Whistling Duck"
This release improves upon the VP9 encoder and speeds up the encoding and

controls and adds a variety of VP9 controls for testing.
The vpxenc utility now prefers VP9 by default.

Faster VP9 encoding and decoding
Smaller library size by combining functions used by VP8 and VP9
- Bug Fixes:
A variety of fuzzing issues
Changelog:
2015-04-03 v1.4.0 "Indian Runner Duck"
This release includes significant improvements to the VP9 codec.
- Upgrading:
This release is ABI incompatible with 1.3.0. It drops the compatibility
layer, requiring VPX_IMG_FMT_* instead of IMG_FMT_*, and adds several codec
controls for VP9.
- Enhancements:
Faster VP9 encoding and decoding
Multithreaded VP9 decoding (tile and frame-based)
Multithreaded VP9 encoding - on by default
YUV 4:2:2 and 4:4:4 support in VP9
10 and 12bit support in VP9
64bit ARM support by replacing ARM assembly with intrinsics
- Bug Fixes:
Fixes a VP9 bitstream issue in Profile 1. This only affected non-YUV 4:2:0
files.
- Known Issues:
Frame Parallel decoding fails for segmented and non-420 files.
is specific to the verion of Clang (3.5 and newer) and not the platform.
This package now builds under Mac OS X Yosemite with the latest version
of Xcode tools.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
* pkg/48508 refers only SunOS and NetBSD (in fact, only NetBSD 5 and
Solaris 10 - but I expect at least lower versions come with same
issues and higher might have improved toolchain)
* check only for x86 architectures (no sse3 on sparc, ppc, arm, mips, ...)
* only require minimum gcc version when gcc is the used compiler - SunPRO,
clang, pcc ... might behave differently
* hopefully someone picks it up and fix the binutils dependency, if required
