title: html5 video / video.js : Are bitrates consistent among devices?
body: <p>I have a video streaming player and get back an array of available video quality bitrates for a stream.  I am trying to set up a custom url param override to set the bitrate but unsure if I should actually use the bitrate number itself.<br />
  On a test stream I have, the highest available bitrate is <code>2341203</code> and it's 720p video.  The lowest is <code>630000</code> and it's 360p video.<br />
  Is it safe to assume that someone always knows the quality of video to expect based on the bitrate, regardless of the device used?  For example, is a bitrate of around <code>2341203</code> always in the 720p range of quality or does it vary depending on the device streaming? If so, I would use a bitrate as a query param:
  <code>http//myvideo.com&amp;bitrate=230000</code> and then find the quality option in the array that has a bitrate closest to that param.<br />
  If bitrate isn't consistent, I was just going to use a &quot;low&quot;, &quot;medium&quot;, &quot;high&quot; scale as a query param</p>
