Description:
https://gitlab.com/AOMediaCodec/SVT-AV1
> The Scalable Video Technology for AV1 (SVT-AV1 Encoder and Decoder) is an AV1-compliant encoder/decoder library core

FFmpeg has a compile option so it can be used with libsvtav1:

> NOTE: If you wish to use an FFmpeg tag or release before 4.4, please go [here](https://gitlab.com/AOMediaCodec/SVT-AV1/tree/v0.8.4/ffmpeg_plugin) and consult that page to properly patch ffmpeg for use with SVT-AV1.
