Using Flash to Provide Multimedia

This section provides a flash video example from YouTube.com. It shows how Flash can be used to provide multimedia information to Web pages.

Flash technology is also widely used to provide multimedia information to Web pages like on-line audio and video players. Here is an example of a Web page using Flash technology to play video online at YouTube.com:
Flash Video Player

By looking at the page source code, you can see how Adobe Flash Player is invoked as a <object> tag to run the video file, watch_as3-vflPSj_0h.swf:

...
      <div id="watch-player" class="flash-player">
  <script>
    (function() {
      var isIE = /*@cc_on!@*/false;
var swfHTML = (isIE) ? "<object height=\"38" + "5\" width=\"64" + "0\"
   classid=\"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000\"
   id=\"movie_player\" >
   <param name=\"movie\"
   value=\"http:\/\/s.ytimg.com\/yt\/swf\/watch_as3-vflPSj_0h.swf\">
   <param name=\"flashvars\"
   value=\"rv.7.length_seconds=27
   &rv.2.thumbnailUrl=http%3A%2F%2Fi2.ytimg.com%2Fvi%2FYH9xhpEaBdo%...

   &is_doubleclick_tracked=1
   &rv.4.thumbnailUrl=http%3A%2F%2Fi2.ytimg.com%2Fvi%2F5XA4AioHMeA%...
   &fmt_url_map=34%7Chttp%3A%2F%2Fv7.lscache1.c.youtube.com%2Fvideo...
   ...   
    allowscriptaccess=\"always\" allowfullscreen=\"true\"
    bgcolor=\"#000000\" \/>
   <noembed>\n\n\n\n  
   <div  class=\"yt-alert yt-alert-error yt-alert-player yt-rounded\">
   <img src=\"http:\/\/s.ytimg.com\/yt\/img\/pixel-vfl3z5WfW.gif\" ...
   <div  class=\"yt-alert-content\">\n            
   You need Adobe Flash Player to watch this video. <br> 
   <a href=\"http:\/\/get.adobe.com\/flashplayer\/\">
   Download it from Adobe.<\/a>\n
   <\/div>\n\n  
   <\/div>\n
   <\/noembed>";
        document.write(swfHTML);
    })();
  </script>
      </div>
...

Notice that the <object> tag is generated from a script code.
