Libvpx, referensimplementering för VP8 och VP9, har nu släppts i en ny version, 1.8.2.

Pekin Duck Release (v1.8.2)

https://chromium.googlesource.com/webm/libvpx/+/v1.8.2

 

 

Rav1e 0.2.0, AV1-kodare skriven i Rust, har släppts, och är åtskilligt snabbare än 0.1.0.

v0.2.0: Yuletide Greetings

Improvements

• Faster, overall 40%–70% faster than v0.1.0 depending on the encoding settings.
• Optional serialization/deserialization of the encoding parameters through the feature serialize
  • Optional cli advanced commands to use it.
• The builds are now using the dwarf debug format for the targets that support it, before it was a mixture of dwarf and stabs due to the nasm defaults.
• Added a --benchmark hidden flag for the cli for MacOS and Linux.
• documentation is now available on docs.rs.

Changes

• Segmentation support is now a tunable SpeedSetting and currently it is default off since it can produce desyncs, this does cause a 3% decrease in quality.

Fixes

• #1903 - edge-of-frame miscomputation
• #1858 - desync on speed 0 and 1 when certain quantizers are selected

Known issues

• #1930 - segmentation encoding may cause desync
