title: Redirecting a broadcast to multicast using ffmpeg
body: <p>Does anyone have experience with this or does anyone know if it can even be done? I know I can stream a saved video file to a UDP IP address, and I know I can take a video stream and save that on to my linux machine but how can I do both at the same time?</p>
  
  <p>I could write a script to save the video from the broadcast coming in and then afterwards multicast that to whatever UDP IP I need, but I can’t afford any lag between the feeds, just a couple seconds at most. Is there a way that I can do this concurrently?</p>
