title: FFmpeg RTP streaming error
body: <p>I want to broadcast a video file via FFmpeg, but I get this error:</p>
  
  <blockquote>
    <p>Only one stream supported in the RTP muxer</p>
  </blockquote>
  
  <p>I get that error when I write this:</p>
  
  <pre><code>ffmpeg.exe -i SomeVideo.mp4 -f rtp rtp://127.0.0.1:11111
  </code></pre>
  
  <p>I don't know what's wrong.</p>
