Replace iFrame src, on click?

Question

Currently I have the list below which needs to update the iFrame inside of an existing div.

<div class="stream">
   <iframe src="" allowfullscreen="true" frameborder="0" marginwidth="0" marginheight="0" scrolling="no"></iframe>
</div>

The above portion is the iFrame we need to update, the below portion is the list of streams we have to choose from on click.

<ul>
    <li class="anime">
        <a class="active" data-video="https://someexamplewebsite.com" href="#" rel=
        "1">Vidstreaming<span>Choose this server</span></a>
    </li>
    <li class="vidcdn">
        <a class="" data-video="https://someexamplewebsite.com" href="#" rel="100">Vidcdn<span>Choose
        this server</span></a>
    </li>
    <li class="streamango">
        <a data-video="https://someexamplewebsite.com" href="#" rel="12">Streamango<span>Choose this server</span></a>
    </li>
    <li class="rapidvideo">
        <a data-video="https://someexamplewebsite.com" href="#" rel="21">Rapidvideo<span>Choose this server</span></a>
    </li>
    <li class="estram">
        <a data-video="https://someexamplewebsite.com" href="#" rel="7">Estream<span>Choose this server</span></a>
    </li>
    <li class="open">
        <a data-video="https://someexamplewebsite.com" href="#" rel="16">Oload<span>Choose this server</span></a>
    </li>
    <li class="open">
        <a data-video="https://someexamplewebsite.com" href="#" rel="5">OpenUpload<span>Choose this server</span></a>
    </li>
    <li class="mp4">
        <a data-video="https://someexamplewebsite.com" href="#" rel="3">Mp4Upload<span>Choose this server</span></a>
    </li>
</ul>

I am wondering how we can make this work easily, and in a way that if the a has a class of active then the iframe is updated with that portions data-video then unsetting the default active on click of another a href
