问题
I have tried to create a function in javascript to mute a html video, and change the icon below to a mute icon that i have downloaded. Need Help. The javascript has to be able to work along side jquery as well

The question is fairly vague, so I'm guessing that this will answer your question. If you are using video tags in HTML
<video width="320" height="240" controls muted>
  <source src="x" type="video/x">
  <source src="x" type="x">
</video>
For Java script
<video id="myVideo" width="x" height="x" controls>
....
</video>
<button onclick="enableMute()" type="button">Mute sound</button>
<script>
var vid = document.getElementById("myVideo");
function enableMute() { 
    vid.muted = true;
}
</script>
As for your second questions, I don't quite understand it, please elaborate.

demo - http://jsfiddle.net/victor_007/6cc9mhbb/
on click of the button the icon will change
$("video").prop('muted', true);
$(".mute-video").click(function () {
    if ($("video").prop('muted')) {
        $("video").prop('muted', false);
        $(this).addClass('unmute-video'); // changing icon for button
    } else {
        $("video").prop('muted', true);
        $(this).removeClass('unmute-video'); // changing icon for button
    }
    console.log($("video").prop('muted'))
});
