      The Scalable Video Technology for AV1 (SVT-AV1 Encoder and Decoder) is an
      AV1-compliant encoder/decoder library core. The SVT-AV1 encoder
      development is a work-in-progress targeting performance levels applicable
      to both VOD and Live encoding / transcoding video applications. The
      SVT-AV1 decoder implementation is targeting future codec research
      activities.
