Thanks to GhostMaster on RCGroup.com, now we know how to get av out working in the Xiaomi Yi Camera for FPV:
1 – Use the Xiaomi Yi app for Android to update the camera firmware to 1.0.7 (avout only works in 1.0.7 or later)
Android app here: http://sports.xiaoyi.com/app/sports_camera.apk
2- After updating the firmware activate avout in camera options in the app.
3- Use this avout cable: SJ4000 USB-AV out cable
4- Have fun 🙂
PS: Be careful using the 5V on the cable to charging, i dont have the confirmation if it works, dont use it until you know it works or you may burn your camera.
Here is another av out testing video, using the SJ4000 usb-av out cable:
