VideoView not playing video from URL in Android -

i tried many links links show same error.but it's giving error "can't play video".

my code following

public class videodemo extends activity {      private videoview video;       private static final string path ="http://www.ustream.tv/embed/6540154?v=3&wmode=direct";       @override      public void oncreate(bundle icicle) {         setcontentview(r.layout.activity_main);          videoview = (videoview) findviewbyid(r.id.videoview);             try {                 // start mediacontroller                 mediacontroller mediacontroller = new mediacontroller(                         videodemo.this);                 mediacontroller.setanchorview(videoview);                 // url string videourl                 uri video = uri.parse(videourl);                 videoview.setmediacontroller(mediacontroller);                 videoview.setvideouri(video);                 videoview.start();              } catch (exception e) {                 log.e("error", e.getmessage());                 e.printstacktrace();             }   } 

}

this because url using not 1 of video of media player plays video.

to play actual video first need find url. 1 way find use livestreamer.

install following instructions , can run command

livestreamer http://www.ustream.tv/embed/6540154 best --stream-url 

the output of command url can use in videoview.
