How to stream video from one device to other? I need to stream video from my Android device to other Android device over Wi-Fi, but I do not want to have a server in between. How can I do this?
You can use IP Webcam, or perhaps use DLNA. For example Samsung devices come with an app called AllShare which can share and access DLNA enabled devices on the network. I think IP Webcam is your best bet, though. You should be able to open the stream it creates using MX Video player or something like that.
