VPX Encoder problem

[Selur]

suddenly started to reverse colors of output videos

sounds like some issue where the colro space isn't properly propagated.

Looking t the encoding call used:

"C:\Program Files\Hybrid\64bit\ffmpeg.exe" -y -loglevel fatal -noautorotate -nostdin -threads 8 -i "C:\Users\SaberAnasterian\AMV.mkv" -map 0:0 -an -sn -pix_fmt yuv420p -vsync 0 -f rawvideo - | "C:\Program Files\Hybrid\64bit\vpxenc.exe" --codec=vp9 --row-mt=1 --passes=1 --pass=1 --end-usage=q --cq-level=18 --profile=0 --good --cpu-used=3 --undershoot-pct=0 --buf-sz=6 --buf-initial-sz=4 --buf-optimal-sz=5 --drop-frame=0 --resize-allowed=0 --kf-min-dist=0 --kf-max-dist=250 --auto-alt-ref=0 --noise-sensitivity=0 --sharpness=0 --static-thresh=0 --tile-columns=2 --tile-rows=1 --min-gf-interval=0 --max-gf-interval=0 --threads=48 --width=1920 --height=1080 --yv12 --color-space=unknown --target-level=255 --input-bit-depth=8 --bit-depth=8 --ivf -o "C:\Users\SABERA~1\AppData\Local\Temp\2021-04-11@19_02_32_5910_01.ivf" -

I see no problem decoder outputs 'yuv420p' and encoder is configured for '--width=1920 --height=1080 --yv12'.
Tested it here and I can reproduce the issue. (swapped u/v channels)
-> looking into it

Will report back.
