Comment (by MasterBlatter):

 I tested it with Zeranoe's lastest x64 build (version N-81664-g6f062eb) on
 my pc and on my father's one, and I get bit-identical files with the same
 artifacts.
 I also tested piping from ffmpeg to vpxenc.exe (the same compiled with
 media-autobuild_suite, so same libvpx as the non vanilla I used) with:
 {{{
 "ffmpeg.exe" -i test17.mkv -pix_fmt yuv420p -f rawvideo - | "vpxenc.exe"
 -t 8 --fpf="test2.log" -w 1920 -h 1080 --i420 --fps=60/1 --codec=vp9
 --cpu-used=2 --good --end-usage=vbr --target-bitrate=500 --passes=2
 --pass=1 --auto-alt-ref=1 --lag-in-frames=25 --color-space="bt709" -o NUL
 -
 "ffmpeg.exe" -i test17.mkv -pix_fmt yuv420p -f rawvideo - | "vpxenc.exe"
 -t 8 --fpf="test2.log" -w 1920 -h 1080 --i420 --fps=60/1 --codec=vp9
 --cpu-used=2 --good --end-usage=vbr --target-bitrate=500 --passes=2
 --pass=2 --auto-alt-ref=1 --lag-in-frames=25 --color-space="bt709" -o
 test2.webm -

 }}}

 The file looks ok.
