Here I’ll add all questions you post in comment :)
- Can I use NextRTC on mobile phone?
Yes, NextRTC is working on mobile phones (It was tested on phones with Android under Chrome). I used mobile phone in all test with STUN/TURN servers, because It was the easiest way to confirm that NextRTC can be used in global network.
- Is it possible to record the video?
Unfortunately NextRTC doesn’t provide this function. NextRTC is only signaling server, so it’s responsible mainly for exchange SPDs. If you want to record video you should consider Kurento project (it provides signaling server + media streaming functionality)
