Created attachment 232273 [details] v1 SVT-AV1 is a mature implementation of a fast AV1 encoder. It makes heavy use of threads and SIMD assembly thus better suited for live streaming (realtime encoding). $ ffmpeg -hide_banner -h encoder=libsvtav1 Encoder libsvtav1 [SVT-AV1(Scalable Video Technology for AV1) encoder]: General capabilities: delay threads Threading capabilities: other Supported pixel formats: yuv420p yuv420p10le libsvtav1 AVOptions: -hielevel <int> E..V.......
