The use case under discussion is changing to another video. So the

is already inserted and already has src.
Something like:
<video controls autoplay>
<source src=video1.webm type=video/webm>
<source src=video1.mp4 type=video/mp4>
</video>
<script>
function loadVideo(src) {
var video = document.getElementsByTagName('video')[0];
sources = video.getElementsByTagName('source');
sources[0].src = src + '.webm';
sources[1].src = src + '.mp4';
}
</script>
<input type="button" value="See video 1" onclick="loadVideo('video1')">
<input type="button" value="See video 2" onclick="loadVideo('video2')">
<input type="button" value="See video 3" onclick="loadVideo('video3')">
Is that really any better than:
function loadVideo(src) {
var video = document.getElementsByTagName('video')[0];
if(video.canPlayType("video/webm") != "") {
video.src = src + '.webm';
}
else {
video.src = src + '.mp4';
}
}

You'd need to remove the <source> elements to keep the document valid.
The author might want to have more than two <source>s, maybe with
media="", onerror="" etc. Then it becomes simpler to rely on the resource
selection algorithm.
