// Pangolin video output supports various formats using
// different 3rd party libraries. (Only one right now)
//
// VideoOutput URI's take the following form:
//  scheme:[param1=value1,param2=value2,...]//device
//
// scheme = ffmpeg
//
// ffmpeg - encode to compressed file using ffmpeg
//  fps : fps to embed in encoded file.
//  bps : bits per second
//  unique_filename : append unique suffix if file already exists
//
//  e.g. ffmpeg://output_file.avi
//  e.g. ffmpeg:[fps=30,bps=1000000,unique_filename]//output_file.avi
