One device is used as an input to the live stream,\nwhile the other is opened by the AI processor.\n\n# Installation\nFor Raspberry Pi 5 only.\n\nEnable PCIe Gen 3.0 speed, install hailo drivers and loopback video device:\n```\nsudo su\necho \"dtparam=pciex1_gen=3\" \u003e\u003e /boot/firmware/config.txt\napt install -y hailo-all v4l2loopback-utils\necho v4l2loopback \u003e\u003e /etc/modules\necho \"options v4l2loopback devices=2 video_nr=50,51\" \u003e /etc/modprobe.d/v4l2loopback.conf\nreboot now\n```\n\n# Troubleshooting\nHailo driver mismatch: The driver on the host must match the version in the container.
