AOMedia Video 1 (AV1) is a relatively new video codec with an initial release on March 28th 2018. It is designed as a replacement for VP9 as well as being a response to the restrictive patent licensing of other video codecs.

The AV1 video codec is aimed to be a state of the art video codec that is aimed to be both patent and royalty free. The codec is currently widely used by YouTube and Vimeo has some videos available in this format while Netflix is experimenting with the codec.

Encoding is available to Ubuntu users by

  1. Using a current (git) FFmpeg compiled against either libaom or rav1e
  2. Using the encoder rav1e from the command line
  3. Using the encoder aomenc from the command line

Both playback and encoding are in the early days but experimentation with the codec shows great promise in an Open Source, royalty free, high quality video codec.
