title: How to write ffmpeg windows command for file path inside double quotes option
body: <p>please help</p>
  <p>I want to use ffmpeg for my c # application but an error appears</p>
  <p>this is my code</p>
  <pre><code>videoPath = @&quot;c:\location\in.mp4&quot;;
  tempVideoPath = @&quot;c:\another_location\out.mp4&quot;;
  
  process.StartInfo.FileName = @&quot;ffmpeg.exe&quot;;
      
  process.StartInfo.Arguments = &quot;-loop 1 -i \&quot;&quot;+tbBGFrame.Text+ &quot;\&quot; -vf \&quot;movie=\&quot;&quot;+videoPath+ &quot;\&quot;,scale=1900:-1[inner];[in][inner]overlay=70:70:shortest=1[out]\&quot; -y \&quot;&quot;+tempVideoPath+&quot;\&quot;&quot;;
  </code></pre>
  <p>the problem is inside movie parameter. i have to include video path inputed by user but its give an error because its already double quote exist before.</p>
  <p>its successfully if i try on windows cmd like this</p>
  <pre><code>&gt; cd &quot;C:\Users\Toshiba\Pictures\test vcp\input_mp4_dir\&quot;
  &gt; ffmpeg.exe -loop 1 -i Coronavirus00000000.jpg -vf &quot;movie=input.mp4,scale=1180:-1[inner];[in][inner]overlay=70:70:shortest=1[out]&quot; -y out.mp4
  </code></pre>
