1. install v4l2loopback device driver
mkdir -p /opt/v4l2loopback; cd /opt/v4l2loopback
git clone https://github.com/umlaeute/v4l2loopback.git
cd v4l2loopback/
make
# as root
make install
modprobe v4l2loopback video_nr=8 card_label="Indi Loopback"
# this will create /dev/video8, to do after each reboot
2. use gstreamer to perform pixel format conversion
# from mjpeg to UYVY for testing
gst-launch-1.0 -v v4l2src device=/dev/video0 ! jpegdec ! videoconvert ! video/x-raw,format=\(string\)UYVY ! v4l2sink device=/dev/video8
# in your case I would suggest
gst-launch-1.0 -v v4l2src device=/dev/video0 ! videoconvert ! video/x-raw,format=\(string\)I420 ! v4l2sink device=/dev/video8
