// Google Chrome maybe supports .src="" but without effect: Playing music don't stop but .src have setted to empty string
//				In this case you MUST set .src to path and file of a dummy-media-file.
// 	This case is not implemented here. You must do it by yourself.
// 	Don't forget to replace all .src="". And dumy-file must have playable codec of media player
//		e.g. HTML-5-media	video .webm or .ogg
//                          audio .oga
//             Internet  Explorer BGSOUND  only audio  .mp3
//  Be shure that this Chroem-feature is implemented in other open browser.
//  Opera don't have this .src-problem of Google Chrome.
//
//  JavaScript code exampe
// 
//  var X01=...;	// this var of actual mediafile with path
//  var X02=...;	// this var contains pointer of media player e.g. for HTML-5-media the pointer of created VIDEO-tag or AUDIO-tag
//  var X03="";
//
//  // ----- check stop
//  if(X01=="")
//  {
//   // get actual media
//   X03=X02.src;
//
//   // ----- check media: only if NOT emtpy then stop possible
//   if(X03!="")
//   {
//    // ---- set dummyfile
//    X02.src= .... ; // filename witth path of dummyfile
//   }
//  }
//
//  Create dummyfile by yourself with all taken codecs.
//   You should know which media you want to play.
//
// To set dummyfile with same codec of last played file you have to do:
//
//  get suffix of last played file (see X01)
//          // get length of X01
//          var X04=X01.length;
//          if(X04>1)
//          {
//           // get pos of last '.'
//           var X05=X01.lastIndexOf("."); 	// at pos 0
//           // check suffix possible ('.' founded)
//           if(X05>=0)
//           {
//            X05++;
//            X04-=X05;  			// length minus pos, both at 1
//                       			// number of chars after '.'
//            if(X04>0)
//            {
//             // get all chars after '.'
//             var X06=X00.substr(X05,X04);
//             // and convert to upper
//             X06=X06.toUpperCase();
//             // now compare with suffixes of all media you want to play
//             if(X06=='WEBM') .... take dummyfile.webm
//             // and so on
//            }
//           }
//          }
//
//   in case of suffix check dummy file
//      if founded suffix '.webm' then take dummyfile.webm
//                        '.mp3'  then take dummyfile.mp3
//                        ......
//       if not founded suffix take empty string.
//
//  put suffixes into array e.g.
//
//        var arPossibleAndAllowedSuffixes=new Array
//        ('WEBM', .... ans so on .... );
//
// At last this:
//      Be shure that entry of arstPL_LastPlayedMedia_SRC is NOT empty.
//      Empty string stops media in Opera Brwoser but not in Chrome.
//      To stop media use only dummyfile.
//
//      Please check .setUrl-Bug of Chrome in use of Quicktime:
//          Path of media should campatible with clearing of bug.
//            Use example of code to clear the bug AND to get path of any mediafile.
//              Create function and use this function for Quicktime too, if you need.

//
// An other nice example of Google Chrome and Quickktime: setUrl-Bug.
//
//      In HTML ist supported SRC and in script ist supported .setUrl().
//
//          Opera use SRC (in script .src) correctly and can use setUrl() too.
//          Using  of .src is very often by handling of objects with SRC (like standard).
//          But Chrome ? Yeahh ... it takes only .setUrl() AND hase same effect like above:
//                              Using of .src have no effect !
//
//          AND in use of setUrl() (Google Chrome)
//              autoplay must be active
//				relative path: media must be contained in same folder of this html document 
//                         OR in folder above of folder of this htmml document
//         				'media/'	wrong
// 					'../media'  okay
//              full path possible too
//
//          BUT in use of .scr (like Opera)
//              autoplay must be active
//		        media can be contained where you want
//         			        'media/'	okay
// 				            '../media'  okay
//              full path possible too
//
//           Example for full path
//
//                   var stFullPathLocal="file:///X:/test/media';                               // local
//                   var stFullPath='';								// actual
//                   if(window.location.hostname!=null){stFullPath=window.location.hostname;}	// if browser online
//                   // stFullPath contains your url of webpage e.g. 'www.test.com'  (but without 'http://')
//                   // Check this string if you want to be shure that webpage runs only from YOUR host, and e.g. not local at other computer.
//                   if(   (stFullPath!='')							// IE, Chrome
//                      && (stFullPath.indexOf('localhost',0)==-1)				// Opera
//                     )
//                   {stFullPath='http://'+stFullPath;}						// if only then http-path for your http-server (e.g. apache)
//                   else{stFullPath=stFullPathLocal;}						// if not online use local path
//                   stFullPath+='/';								// don't forget / at end
//
//
// Opera and Chrome are not compatible.
