[Cin] vp9 row-mt parameter?

I found this thread while looking at av1 parameters.. https://stackoverflow.com/questions/41372045/vp9-encoding-limited-to-4-threa... ==== Apparently since ffmpeg 3.3/libvpx 1.6.2, there is now support -row-mt=1 option which provides better encoding parallelization and more than 4 threads for 1080p content. Threadripper guys go nuts! - groups.google.com/a/webmproject.org/forum/#!topic/codec-devel/… – Programster Oct 29 '17 at 10:15 === As some people in comments and below have already commented, more recent versions of libvpx support -row-mt 1 to enable tile row multi-threading. === we use libvpx 1.8.2 / ffmpeg 4.3 so it should be applicable to us can anyone test few vp9 profiles modified with this parameter?
