Description
A command like this can be used to capture still images from a V4L device:
mpv --demuxer-lavf-format=video4linux2 --demuxer-lavf-o-set=input_format=mjpeg --frames=1 -o /tmp/s.png /dev/video2
or this for non jpeg compressed yuv video:
mpv --frames=1 -o /tmp/s.png /dev/video2
Required hardware for first tests:
- HDMI Cable: https://www.reichelt.de/raspberry-pi-adapter-micro-hdmi-auf-hdmi-1m-schwarz-rpi-m-hdmi-hdmi2-p270099.html (normal HDMI for RPi3b(+) and miniHDMI for Zero2W)
- HDMI Capture device: https://www.reichelt.de/hdmi-video-capture-stick-usb-typ-a-delock-88307-p319564.html or https://smile.amazon.de/foo/dp/B08K43M3ZB/
- USB Hub(s) (we don't have free ports at current worker): https://www.reichelt.de/usb-3-0-4-port-alu-hub-schwarz-icy-ib-hub1409u3-p218402.html
This could be used to ensure that the console - or even xserver is displaying anything via HDMI output.
