Av1an and vmaf
Another encoder for AV1, but not only. It has many features including multithreading, which is one of the biggest problems of AV1. It looks very interesting:
By the way, av1an also uses an algorithm developed by Netflix. It is already included in ffmpeg, but you have to enable it.
Does anyone know and use these projects?
Vmaf: it is a type of license (still Open) called: BSD + patent:
Instead Av1an is completely Open: GPL 3:
It would be good to have a new encoder for AV1, because the standard is quite slow. I don't think it's easy to implement it, though?
It seems that the ffmpeg provided by Arch linux already implements vmaf.
