title: HTML5 video player some mp4 files not playing chrome
body: <p>So I'm trying to build a personnal streaming platform and I've done my best to follow the recommandations I've found everywhere for better compatibility/quality when streaming.</p>
  
  <p>So I'm systematically encoding my video to video codec h264 with mp4 container with ffmpeg using this command:</p>
  
  <pre><code>ffmpeg -i input -vcodec libx264 -maxrate 8000k -bufsize 1000K -minrate 10k -crf 24 -ab 192k -movflags faststart output.mp4
  </code></pre>
  
  <p>However, I occasionaly fall on some reluctant mp4 that will play fine on Edge and Firefox but won't on Chrome. Loading seems to be processed fine as I can see the total duration in the controls, but it will never play and will not leave any error in the console.</p>
  
  <p>Here's a Mediainfo export of such reluctant file:</p>
