title: What video codecs work on Google Chromebook
body: <p>I'm trying to put a show on my friends Google Chromebook but the mp4 files show up black when trying to watch them on said Chromebook, audio works fine. I found out that it is a video encoding problem but I cannot find a list of video formats that work on the Chromebook. I have ffmpeg and handbrake to try and test some things, but if someone could tell me a ffmpeg code that will convert the video files into a format that works on a Google Chromebook that would help a lot.</p>
  
  <p>What I've tried:</p>
  
  <pre><code>ffmpeg -i "Game of Thrones S02E01 The North Remembers.mkv" codec mpeg "Game of Thrones S02E01 The North Remembers.mp4"
  </code></pre>
  
  <p>Which gives error:</p>
  
  <blockquote>
    <p>[NULL @ 00000177196ea500] Unable to find a suitable output format for
    'codec' codec: Invalid argument</p>
