Trouble adding video as background

Question

i've looked around online and have tried two different methods, however, both don't seem to be working.

I need to make a video cover a whole webpage background (i've done it like so) -

css -

video#bgvid {
    position: fixed;
    top: 50%;
    left: 50%;
    min-width: 100%;
    min-height: 100%;
    width: auto;
    height: auto;
    z-index: -100;
    -ms-transform: translateX(-50%) translateY(-50%);
    -moz-transform: translateX(-50%) translateY(-50%);
    -webkit-transform: translateX(-50%) translateY(-50%);
    transform: translateX(-50%) translateY(-50%);
    background: url(polina.jpg) no-repeat;
    background-size: cover;
}

HTML -

This however doesn't load anything onto my website background... am i missing something here / is there a simpler solution?

another way i tried is, with no luck is -

CSS-

.fullscreen-bg {
    position: fixed;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    overflow: hidden;
    z-index: -100;
}

.fullscreen-bg__video {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
}

HTML-

Thanks in advance guys, any help would be much appreciated.
