Comment:

 There is no problem for ffmpeg; it's a playback problem it's "gbrp"
 because input is rgb24 png

 ffplay plays it normally

 Convert to YUV if you need YUV VP9 compatible with other programs like
 chrome

 eg.
 ffmpeg -i input.png -c:v libvpx-vp9 -vf format=yuv420p -crf 30 -b:v 0
 yuv420p.webm
