title: FFmpeg android execute
body: <p>On windows I could cut a video with below code with ffmpeg.exe</p>
  
  <p>Can't use ffmpeg in android.
      I used gradle to grab ffmpeg in my app.</p>
  
  <pre><code>dependencies {
  compile fileTree(dir: 'libs', include: ['*.jar'])
  compile 'com.github.hiteshsondhi88.libffmpeg:FFmpegAndroid:0.2.5'
  }
  </code></pre>
  
  <p>I have these lines in my method</p>
  
  <pre><code>VideoIn = getInternalDirectoryPath() + "/Download/Ab.mp4";
  VideoOut = getInternalDirectoryPath() + "/Download/Ab1.mp4";
  
  try {
  ffmpeg.execute("ffmpeg -i " + VideoIn + " -ss 00:00:03 -c:v libx264 -crf 17 -t 00:00:5 " + VideoOut + " -y",null);
  }
  catch (FFmpegCommandAlreadyRunningException e) { 
  e.printStackTrace();
  }
  </code></pre>
  
  <p>Shows this error: Error running exec(). Command: [/data/data/com.videoeditor.myname.myapp/files/ffmpeg, ffmpeg, -i, /storage/emulated/0/Download/Ab.mp4, -ss, 00:00:03, -c:v, libx264, -crf, 17, -t, 00:00:5, /storage/emulated/0/Download/Ab1.mp4, -y] Working Directory: null Environment: null</p>
  
  <p>What's wrong with this method? Thanks for your help</p>
