You just have to unlink previous library (like react-native-controls) if installed, then uninstall this previous library, unlink react-native-video and link it again
I think the problem is the caused by installation of more than one react-native-video. Use "npm list | grep react-native-video" to check how many react-native-video versions in your project.
