 I'm interested in creating the dual-fisheye video using ffmpeg using my
 raspberry pi. I've been using Raspivid to do this up until now but I'm
 curious to try it with ffmp3g and see if there are any benefits. My
 interest is be to record two, say, 1024x1024 videos at the same time and
 then, when recording is done, combine them into a single 2048x1024 mp4
 video. Is ffmpeg capable of forcing a 2nd camera to mirror the auto-
 exposure of a 1st cameras. So if the dual-camera goes into a tunnel etc
 the 2nd camera would adjust it's settings automatically from the 1st
 camera?

 So, the question is this:
 What ffmpeg statement would be used to simultaneously record 1024x1024
 from two attached cameras at 30fps WHILE keeping the two cameras
 synchronized in terms of exposure?
