Solution for issue required: Launch of Video Player from Website in webview

I have Android application which opens Web application in webview. The website which opens in webview has list of Youtube videos with 3GP and MP4 urls to play video. What is expected is that video should be launched in device's video Player. Current app can be installed on device and opens website in it. App is facing issue of playing video. What should happen is, any link clicked within website(opened in webview) should launch video player and user should be able to watch youtube video streaming. I shall provide app source code for rectifing issue. Developer need to provide me rectified code back with tested APK file.
