How To Create A Thumbnail Image From A Video In A JavaScript Application

I want to create a thumbnail from a video so it can be uploaded alongside the video itself to a server. I have tried searching for js libs to do the work but cant seem to find any

Solution 1:

Using Canvas you can capture the video Thumb. here is the working example.

function thumbnail(){
    var canvas = document.getElementById('canvas');
    var video = document.getElementById('video');
    canvas.getContext('2d').drawImage(video, 0, 0, video.videoWidth, video.videoHeight);
}
document.getElementById('capture').addEventListener('click', function(){
	thumbnail();	
});

<button id="capture">
  capture
</button>
<canvas id="canvas"></canvas>
<video width="320" height="240" id="video" controls>

Your browser does not support the video tag.
