When using this with chrome, my image seems to be flipped horizontally:

For example when capturing a screen:

 ffmpeg -f x11grab -r 30 -s 1920x1080 -i :1.0+0,0 -vf hflip -vcodec rawvideo -pix_fmt yuv420p -threads 0 -f v4l2 /dev/video1

using -vf hflip is necessary.

It seems to be ONLY for Google Chrome (not Firefox, bluejeans or zoom), and I found: https://bugs.chromium.org/p/webrtc/issues/detail?id=3769

Not an issue with the sink plugin

$ v4l2-ctl -c horizontal_flip=1

might help (although this does not seem to work with v4l2loopback). Back to Firefox ...
