Bug 1513973 - Make MediaEngineSource::SetTrack return void. r=jib All subclasses are now returning NS_OK, so there's no point in keeping nsresult as the return type. Differential Revision:

<!DOCTYPE html>
<html reftest-zoom="2" class="reftest-wait">

    <script type="application/javascript">
    // reftest-zoom is only applied at onload, so ensure the source-selection
    // has happened after that
    function clearWait() {
    window.addEventListener("load", function() {
      setTimeout(function() {
        var img = document.querySelector("img");
        img.onload = clearWait;
        img.onerror = clearWait;
        img.src = img.src;
      }, 0);
