      <source type="video/mp4" src="video/myvid.mp4" media="(orientation:landscape)">
    </video>
  </div>

  <div id="buttonbar">
    <button id="volDn">
      <img src="images/video/menos.png" id="menos" />
    </button>
    <button id="volUp">
      <img src="images/video/mais.png" id="btn-mais" />
    </button>
    <button id="mute">
      <img src="images/video/som.png" id="btn-mudo" />
    </button>
  </div>
  <div id="bg-video"></div>
</header>

Note: I was having problems with position: absolute I switched to relative only this problem persists there, I'm trying to fix it, but it does not work.

See if this code helps you, in which case the video becomes responsive. (class="embed-responsive-item")

<video autoplay loop id="volume-js" class="embed-responsive-item">
   <!-- Default video source: -->
   <source type="video/mp4" src="myvid.mp4" media="(orientation:landscape)">
</video>
