title: WPF-MediaKit cant render some H264 video on my project but it can elsewhere
body: <p>I'm trying to use the MediaUriElement from WPF-MediaKit, it works fine for every format I've tested except with the H264 format.</p>
  
  <p><img src="https://i.stack.imgur.com/GukRb.png" alt="Left: My application, Right: WPF Mediakit Sample application, Video codec: Codec H264 - MPEG-4 AVC (part 10)(avc1), FrameRate: 29.969000, Res:320x240"></p>
  
  <p>Picture: Left: My application, Right: WPF Mediakit Sample application</p>
  
  <p>Whats strange is that WPF mediakit in my application can play file that is: </p>
  
  <pre><code>Codec H264 - MPEG-4 AVC (part 10)(avc1), FrameRate: 24.000384, Res: 1920x872
  </code></pre>
  
  <p>But it cant play: (i'm using this video as an example, it cant play other similar videos)</p>
  
  <pre><code>Codec H264 - MPEG-4 AVC (part 10)(avc1), FrameRate: 29.969000, Res: 320x240
  </code></pre>
  
  <p>I spent a fair while looking through the source code for the WPFMediakit sample application, but i couldn't figure out what they did diffrently.</p>
  
  <p>I have K light codec installed and Windows media player can play the videos.</p>
  
  <p>If you need other information I'll be happy to provide them.</p>
