alienatedsec/yi-hack-v5 — reverse-engineered prompt

Build me a custom firmware project for supported Xiaomi Yi cameras that lets people keep using the camera normally but unlock the useful stuff the stock firmware is missing. I want free RTSP streaming, ONVIF support, motion events over MQTT, a simple browser based control panel, snapshots, PTZ controls for dome models, and basic services like SSH, FTP, and optional telnet. It should also let the user change common camera settings like status light, infrared light, rotate, detection sensitivity, recording mode, and camera on or off, and give them the option to disable cloud features while keeping local streaming.

Please make it work for the Yi Home, Yi 1080p Home, Yi Dome, Yi 1080p Dome, Yi 1080p Cloud Dome, and Yi Outdoor models that match the supported base firmware. I also want the flashing and setup flow to be simple, using a FAT32 microSD card with the right firmware files and a folder copied to the card, then a web page for setup after boot. If anything is unclear, look up the current docs and releases online.
