+// 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
