 Re: WebM, nio år senare
Libvpx 1.8.1 är på gång. Beskrivningen är dock rätt märklig. Orpington Duck Release CandidateJohann Koenig skrev: The Orpington Duck is a hybrid composed of ducks from previous libvpx releases: Aylesbury (v0.9.5), Cayuga (v0.9.7), and Indian Runner (v1.4.0). We will be finalizing a v1.8.1 release soon. If you have any issues with the current branch please let us know.

 Re: WebM, nio år senare
Rav1e 0.2.0 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
