This is a client for dynamic DNS services, aimed at ESP (ESP32, etc) devices. Your node can use such a service to make its IP address known as a public DNS name, so you can find it, and use it from applications.
Sony IMX-series MIPI-CSI camera sensor drivers for the ESP32-P4 esp_cam_sensor / esp_video framework, plus the DW9807 autofocus VCM. Brings the Raspberry Pi Camera Module 3 (IMX708) to the ESP32-P4: streaming, ISP tuning, autofocus and five resolution modes switchable at run time. Also drives the Raspberry Pi Camera Module v2 / NoIR v2 (IMX219): streaming, ISP tuning, stills and H.264 video, verified on hardware. The v2 module is fixed-focus, so no autofocus there.
