title: how to loop audio to a ffmpeg generated video
body: <p>i am a beginner programmmer and am trying to implement ffmpeg. I am trying to convert a bunch of images to video and add a audio background. Can anybody help me and tell me how to loop the audio as required by the length of the video generated.</p>
  
  <p>PS. This number of images varies so can we implement something that dynamically loops the audio as required   </p>
