Can Unity Play videos in loop-mode on ios device, and recieve response when touch events happen

While I'm far from an expert in this area, I would say no. The only way using Unity standard functionality you can play videos is Handheld.PlayFullScreen$$anonymous$$ove(), and I'm fairly sure (cannot test it at the moment), that Unity is suspended while the movie is playing. There are callbacks you can use to detect when Unity is suspended and resumed. Alternately there are plugins that play movies within Unity that would allow you to continue to get input.

thanks robertbu. But, the actual need is that we want play a loop-video on the back layer of a UI menu. So, when the menu is touched, video will stop and game begins. And,we have tried movietexture, but it is not supported on iOS or Android device. $$anonymous$$aybe, plugins is a alternate way.
