In Chrome 55, prevent showing Download button for HTML 5 video

This is the solution

 //From this post  http://stackoverflow.com/questions/39602852/disable-download-button-for-google-chrome/40975859#40975859

   video::-internal-media-controls-download-button {
    display:none;
   }
   video::-webkit-media-controls-enclosure {
        overflow:hidden;
   }
   video::-webkit-media-controls-panel {
        width: calc(100% + 30px); /* Adjust as needed */
   }

Chrome should provide web developers with an API way of enabling / disabling this feature. This was requested here: https://bugs.chromium.org/p/chromium/issues/detail?id=675596&can=2&q=media%20download&colspec=ID%20Pri%20M%20Stars%20ReleaseBlock%20Component%20Status%20Owner%20Summary%20OS%20Modified

This can hide download button on Chrome when HTML5 Audio is used.

 #aPlayer > audio { width: 100% } 
        /* Chrome 29+ */ 
@media screen and (-webkit-min-device-pixel-ratio:0) 
  and (min-resolution:.001dpcm) { 
       /* HIDE DOWNLOAD AUDIO BUTTON */ 
     #aPlayer { 
           overflow: hidden;width: 390px;  
        } 
 
    #aPlayer > audio { width: 420px; } 
} 
 
/* Chrome 22-28 */ 
@media screen and(-webkit-min-device-pixel-ratio:0) { 
     
      #aPlayer { 
           overflow: hidden;width: 390px;  
        } 
 
    #aPlayer > audio { width: 420px; } 
}

<div id="aPlayer"> 
 <audio autoplay="autoplay" controls="controls"> 
  <source src="http://www.stephaniequinn.com/Music/Commercial%20DEMO%20-%2012.mp3" type="audio/mpeg" /> 
 </audio> 
</div>
