title: Widevine and MPEG-DASH - offline playback
body: <p>I have created an Android application which is capable of playing movies, which are protected with DRM (Widevine Modular). Video are in MPEG-DASH standard. In case, that device is online, everything works fine.</p>
  
  <p>Now I need to add feature for playing video in offline mode. The problem is that I do not know how can I download some file(s) for offline playback. Everything what I have is <code>.mpd</code> file, which contains structured data.</p>
  
  <p>How can I get some file(s) for download from this manifest <code>.mpd</code> file? There are no direct links to some video. I see some chunk, which looks like this:</p>
  
  <pre><code>media="chunk_ctvideo_cfm4s_rid$RepresentationID$_cs$Time$_w1003607280_qaWQ9QVBsSUxIMUpaRnVfdfdfkstMDImYXdsgdreaW9pbmRleD0w_mpd.m4s
  </code></pre>
  
  <p>I do not know if it is useful for me, but there is nothing more "noticeable" in the manifest file.</p>
