title: How to generate SDP file from FFMPEG
body: <p>So, I have been working with FFMPEG on a project that involves streaming video from one computer to another across the internet with RTP. I want to take that into ffmpeg and use ffserver to display it on a local network.</p>
  
  <p>As I understand it, you need to have a SDP information so that the receiving ffmpeg instance can interpret the RTP stream. Despite what webpages say, I can not find the SDP information in the information printed to the console.</p>

  -s 352x240 -deinterlace -y 2005.mp4 -an -threads 0 -r 10 -g 45 -s 352x240
