title: downloaded video from google photos api do not have best quality
body: <p>I am using Google Photos API to download my photos and video.
  The <a href="https://developers.google.com/photos/library/guides/access-media-items#video-base-urls" rel="nofollow noreferrer">API docs</a> say: </p>
  
  <blockquote>
    <p>To access the bytes of a video mediaItem, concatenate the baseUrl with the download video, dv parameter.</p>
    
    <p>The dv parameter requests a high quality, transcoded version of the original video. The parameter is not compatible with the w and h parameters.</p>
  </blockquote>
  
  <p>But video, that downloaded from "base_URL=dv" dont have best quality. 
  If i download video with browser from <a href="https://photos.google.com/" rel="nofollow noreferrer">https://photos.google.com/</a> it have more size (28 MB) and have 60 fps, but the same video from "base_URL=dv" have small size (18 MB) and 30 fps. Audio track in video also below in video downloaded from "base_URL=dv".</p>
  
  <p>How can I get a URL to download a video with original quality (like from the browser) from the Google Photos API?</p>
