title: Error reading a 4k (4kUHD) video in MATLAB 2014b in Windows 7
body: <p>I try to read a 4k video in Matlab. I use the next code:</p>
  
  <pre><code>vision.VideoFileReader('my_file.mp4', ...
                                'ImageColorSpace', 'RGB', ...
                                'VideoOutputDataType', 'uint8');
  </code></pre>
  
  <p>The video file is obtained from GoPro camera and the MPEG-4 H264 codec is used to compress the video. The resolution of each frame is 3840 x 2160 pixels, so it is indeed the 4k UHD video. I got the next error:</p>
  
  <pre><code>Error using coder.internal.errorIf (line 9)
  Unable to read video from the file. Use dsp.AudioFileReader to read audio content.
  Error in vision.VideoFileReader/setFileInfoProps (line 352)
  Error in vision.VideoFileReader/set.Filename (line 150)
  Error in matlab.system.SystemProp/parseInputs (line 908)
  Error in matlab.system.SystemProp/sysObjSetProperties (line 298)
  Error in vision.VideoFileReader (line 133)
  </code></pre>
  
  <p>The video from the same camera (meaning the same codec), but using resolution 1920 x 1080 pixels,can be read without any errors.</p>
  
  <p>I use Matlab R2014b (64-bit), Windows 7 Professional. </p>
  
  <p>Any ideas how I can read the 4k video without converting it to different format? </p>
