title: FFMPEG: [flv @ 0xbeee10] Non-monotonous DTS in output stream
body: <p>I'm using FFMPEG to take my IP camera's RTSP stream and send it to my streaming server as RTMP. When I run the command, I get 5 of the below error and then the stream does start. However, if I let it go overnight, it will stop streaming and fill up terminal with this error as well.</p>
  
  <pre><code>[flv @ 0x191ba0] Non-monotonous DTS in output stream 0:0; previous: 0, current: -202; changing to 0. This may result in incorrect timestamps in the output file.
  </code></pre>
  
  <p>Is there something wrong with my FFMPEG command? </p>
