I have embedded HTML5 video with mp4 format. How to get thumbnail image like poster without using "poster" attribute. This problem coming on Safari and iOS. I have added video like below mentioned code.

<video height=350 id='TestVideo' webkit-playsinline><source src='test.mp4' type=video/mp4></video>

On Chrome, IE, Firefox first frame of video coming as thumbnail image, but not coming on Safari and iOS.

simply add preload="metadata" in video tag and set #t=0.1 at url src, it will get the frame of 0.1s of your video as thumbnail

however, the disadvantage of this solution is when you click to play the video, it always start at 0.1s

<video preload="metadata" controls>
    <source src="video.mp4#t=0.1" type="video/mp4">
</video>

How to get HTML5 video thumbnail without using poster - iOS, I have embedded HTML5 video with mp4 format. How to get thumbnail image like poster without using "poster" attribute. This problem coming on Safari and iOS. There are a few things wrong with the above code. Not sure how the poster was able to even run this. But you need to get a better name for the file you will be saving. Line:54. As this grabs the entire url for the video and then sends that off as the file name. I would suggest stripping the last 4 lines of the videos[index-1] at the same place.

If you want to do this without storing server side images it is possible, though a bit clunky... uses a canvas to record the first frame of the video and then overlay that over the video element. It may be possible to use the URL for the Canvas as a source for the Poster (eg video.poster = c.toDataURL();) but that requires correct CORS setup (not sure if the video was on your own server, and if you have control over that, so took the safest option). This will work best if video is correctly encoded for streaming (so MOOV atom is at the front of the video, otherwise it will be slow to draw the overlay - see this answer for more detail)

The HEAD contains styling for the video and the overlay (you will need to adjust sizing and position to suit your application)

<head>
  <style>
    video_box{
      float:left;
    }
    #video_overlays {
      position:absolute;
      float:left;
      width:640px;
      min-height:264px;
      background-color: #000000;
      z-index:300000;
    }
  </style>
</head>

In the BODY you will need the div for the overlay and the video. The overlay div has an onclick handler to hide the overlay and start the video playing

<div id="video_box">
  <div id="video_overlays" onclick="this.style.display='none';document.getElementById('video').play()"></div>

    <video id="video" controls width="640" height="264">
      <source src="BigBuck.mp4" type='video/mp4'>
    </video>

  </div>
</div>

Finally you will need code that will load the video, seek to the first frame and load the visual into a canvas that you then insert into the overlay

<script>

function generateOverlay() {
    video.removeEventListener('seeked',generateOverlay);  / tidy up the event handler so it doesn't redraw the overlay every time the user manually seeks the video
    var c = document.createElement("canvas");
    var ctx = c.getContext("2d");
    c.width = 640;
    c.height = 264;
    ctx.drawImage(video, 0, 0, 640, 264); // take the content of the video frame and place in canvas
    overlay.appendChild(c); // insert canvas into the overlay div
}

    // identify the video and the overlay
    var video = document.getElementById("video");
    var overlay = document.getElementById("video_overlays");

    // add a handler that when the metadata for the video is loaded it then seeks to the first frame
    video.addEventListener('loadeddata', function() {
        this.currentTime = 0;
    }, false);

    // add a handler that when correctly seeked, it generated the overlay
    video.addEventListener('seeked', function() {
    // now video has seeked and current frames will show
    // at the time as we expect
        generateOverlay();
    }, false);

    // load the video, which will trigger the event handlers in turn
    video.load();

</script>

Hack for iOS Safari to display the HTML video thumbnail � Muffin Man, No comments. Mobile iOS Safari doesn't display preview thumbnail until you tap on the video. My go-to solution was to define a poster attribute� Show a video poster or thumbnail before the video is started. If the video is not played automatically it’s a good idea to show a video thumbnail and thus give viewers a glimpse of the content. For the video to have a poster you simply need to add the poster attribute and the URL to the poster image:

this is a bit late but we had the same scenario. I can't use the attribute 'muted' because my videos are podcasts. This is what I came up with and I hope to share it with future visitors. What I did is load the video in the body tag, drew a canvas, retrieved as base64 and applied to the video as the background image.

Since my video should be fixed 150px in height, I computed the aspect ratio so that whatever height and width of the actual video, it will be resized into 150px height and dynamic width.

$('body').append('<video class="checkmeload" style="position:absolute;top:-10000px" controls preload="auto" playsinline src="//src-here"><source src="//src-here" type="//videotype-here"></video>');

$('body').find('.checkmeload').on('loadeddata', function(){
    var video = $('.checkmeload');

    var canvas = document.createElement('canvas');
    aspectratio = (video[0].videoWidth / video[0].videoHeight);
    newwidth = (150 * aspectratio);
    canvas.width = newwidth;
    canvas.height = 150;

    var context = canvas.getContext('2d');
    context.drawImage(video[0], 0, 0, canvas.width, canvas.height);
    var dataURI = canvas.toDataURL('image/jpeg');

    $('body').find('.checkmeload').remove(); 

    $('#myvideo').css('background-image','url("'+dataURI +'")');
});
