This information was answered specifically about timing source 
information, but what about the general question? I'm encoding an .h264 
file, and would love to put packets inside that identify my software 
version, incoming stream IP, ffmpeg version - e.g., once every SPS/PPS 
comes along.


Is there a simple way to do that with ffmpeg? What are the best google 
keywords to figure this out if not?
