In the changelog of ffmpeg 4.2 it was announced that Dav1d will be integrated. As far as I know it is faster than AOM.

Andrea, thanks for the notify.
Looks like they've disabled multithreading. Is it important for CinGG?
AOM is very slow, because I think that the version GG added was not multi-threaded. But maybe since then multi-threading was added to a newer version and then removed? Anyway, ffmpeg is supposedly adding Dav1d and it is faster according to Andrew earlier email. But it is not yet in a released ffmpeg (I think it will be in the upcoming 4.2 version). This reply is mostly speculative and may not even be correct! Phyllis
