title: Safari on iOS 15 inline video playback issues
body: <p>A webpage containing <code>video</code> element with <code>src</code> attribute set to a Data URI containing a video file does not play the video in Safari on iOS 15.</p>
  <p>Inspecting the device/simulator with Safari Dev Tools suggests the browser repeatedly issues requests with <code>Range: bytes N-M</code> headers, reading the whole video file multiple times, leading to huge memory consumption and eventual failure to start the playback.</p>
  <p>If the video is small enough and does manage to start, the playback appears sluggish and takes enormous time to even start.</p>
  <p>Is there any workaround for this problem?</p>
  <p>P.S. Keeping the video in Data URI is inherent to the task I am trying to solve, so please refrain from suggesting to keep the video file as a separate resource :)</p>
