Yi Technology Releases an Open API SDK for Yi and Yi 2 4K Action Cameras

Yi Technology, the maker of Yi actions cameras, often wrongly reported as Xiaomi Yi cameras as they are sold in Xiaomi stores, has now released an Open API to allow software and hardware engineers to develop products – such as drones, robots, or 360 deg. video recording setups – using their cameras. YiOpenAPI supports three types of APIs available in Java or Swift languages: Camera control (start/stop recording, capture picture, turn on/off viewfinder, etc…) Camera settings (date/time, video resolution, photo size, video standard, etc…) Camera state (record started/completed, video finder started etc…) There are also some app samples, one of which being YI360Demo available in both binary and source code, and used to control multiple Yi cameras in order to shoot 360 deg. / VR  videos. You can find YiOpenAPI on github, get support on YiOpenAPI Facebook group, and sign-up for news updates on YiOpen.com.

So there are not usable for most people, unless maybe if you somehow need a 4K CCTV camera. Currently one of the cheapest “true” 4K action cameras is Yi Technology / Xiaomi Yi 2 sports camera based on Ambarella A9S SoC, capable of recording up to 4K @ 30 fps, and selling for around $250. But there’s now a new wave of cheaper “4K 30 fps cameras” based on Ambarella A12S75 Cortex A9 …
