title: How can I limit FFMpeg CPU usage?
body: <p>I am calling FFMpeg inside a C# Windows Forms application. Since it uses so much CPU (always above 90%), none of my threads can continue working. Is there a way to limit this CPU usage?</p>
  
  <p>I've tried to set Process.PriorityClass to PriorityClass.BelowNormal but this totally blocked the ffmpeg process.</p>
  
  <p>I am sure there is a way to do this since I see a lot of programs that utilize ffmpeg.</p>
  
  <p>Please help.</p>
