body: <p>How to set useragent in ffmpeg ?.</p>
  
  <p>I implemented SWF verification in Media server and allowed some user agents for not to check SWF. But Problem is, I'm unable to set useragent in FFMPEG. As I need to repubish one of my stream with low bit rate to core server using ffmpeg. </p>
  
  <pre><code>FFMPEG Version : ffmpeg version 1.2.6-7:1.2.6-1~trusty1
  
  SWF verification enabled in 172.20.1.10 server
  </code></pre>
  
  <p>Tried formats : </p>
  
  <pre><code>ffmpeg -re -i "rtmp://10.11.12.13/live/mystreams -c copy -f flv  "rtmp://172.20.1.10/live/testnew -headers "UserAgent: 'FMLE/3.0 (compatible; FMSc/1.0)'"
  
  ffmpeg -re -i "rtmp://10.11.12.13/live/mystreams -c copy -f flv  "rtmp://172.20.1.10/live/testnew -user_agent 'FMLE/3.0 (compatible; FMSc/1.0)'"
