WebM is an open, royalty-free, media file format designed for the web.

WebM defines the file container structure, video and audio formats.
WebM files consist of video streams compressed with the VP8 or VP9 video codec
and audio streams compressed with the Vorbis audio codec.
The WebM file structure is based on the Matroska container.

2020-07-31 v1.9.0 "Quacking Duck"
This release adds support for NV12, a separate library for rate control, as
well as incremental improvements.

- Upgrading:
NV12 support is added to this release.
A new interface is added for VP9 rate control. The new library libvp9rc.a
must be linked by applications.
Googletest is updated to v1.10.0. is compiled into a new library libsimple_encode.a with

- Enhancement:
Various changes to improve VP9 SVC, rate control, quality and speed to real
time encoding.

- Bug fixes:
Fix key frame update refresh simulcast flexible svc.
Fix to disable_16x16part speed feature for real time encoding.
Fix some signed integer overflows for VP9 rate control.
Fix initialization of delta_q_uv.
Fix condition in regulate_q for cyclic refresh.
Various fixes to dynamic resizing for VP9 SVC.

2019-12-09 v1.8.2 "Pekin Duck"
This release collects incremental improvements to many aspects of the library.

- Upgrading:
ARCH_* defines have been removed in favor of VPX_ARCH_*.

2019-07-26 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/ for alternatives.
All PPC optimizations have been disabled:

- 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.

2019-05-11 added (v1.0.0) to provide support for av1 video codec

2019-01-31 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:
- Frame dropping in SVC.
- Inter-layer prediction in SVC.
- Enable long term temporal reference in SVC.
- Extend and improve this control for better flexibility in setting SVC
pattern dynamically.
- Allow for post-encode frame dropping (applies to non-SVC too).
- Enable spatial layer sync frames.
- Extend api to specify temporal id for each spatial layers.
- 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.
