Sorry, I ask the question here is to ensure whether mencoder supports pipe out. (mencoder man page only shows a pipe sample). ("pipe out" means write to stdout, and "pipe in" means receive data from stdin).
And your above command is not pipe, neither pipe in nor pipe out. You use mencoder to write a file.avi instead of stdout and use ffmpeg read data from file.avi instead of stdin. 
Why I want to use pipe? Because your above sample command need to write a big file.avi to hard disk and pipe doesn't need it!
