iPhone can not play video from my web page (server)

I am streaming video using NanoHTTPD from android device. Every device can play the video file in web page or using external media player except iPhone. Even Mac desktop can play the file too. I manually pushed the video file into iPhone and it's playable. So there is no issue about video format. When i click on the link iPhone open a video player (inside web page) and nothing happen.
