I want to use an iPhone (not jailbroken) as a camera and stream the live video to an Android (CyanogenMod) tablet.
Restrictions:
This must work without Internet. The devices are in the same WLAN, and they are close enough to each other that Bluetooth would work.
The video must not be saved (but an option for this is fine).
The solution should ensure that only this specific tablet can receive the stream, not any eavesdroppers.
All involved software must be gratis (ideally FLOSS in addition).
