The scrcpy project is already great for this: https://github.com/Genymobile/scrcpy

Here's a little script for streaming through your camera on obs:

get-adb-devices-list() { adb devices | grep -v "List of devices attached" | grep -v "daemon" | grep -v "^$" | grep -c . }

echo "device count: $(get-adb-devices-list)" while [ "$(get-adb-devices-list)" -eq 0 ]; do echo "Waiting for the device..." sleep 0.5 done

IP_ADDRESS=$(sudo adb shell ip addr show wlan0 | grep "192.168.." | awk -F ' ' '{print $2}' | cut -d '/' -f1)

connect-adb-tcp () { sleep 1 echo "Connect to the device...$IP_ADDRESS" && \ adb tcpip 5555 && \ sudo adb connect "$IP_ADDRESS" }

connect-adb-tcp && \ v4l2-ctl --list-devices && \ scrcpy -e --v4l2-sink=/dev/video0 --lock-video-orientation=1 -n -N &> ./log & obs
