Comment:

 I hereby report that the [https://ffmpeg.org/ffmpeg-protocols.html#toc-
 pipe documentation] appears to suggest that only two output pipes are
 available in ffmpeg.  That's a bug, I think.

 Eventually I learned that...

 Any number of unnamed output pipes is supported, provided all output pipes
 are inherited from a parent process that creates them, allows them to be
 inherited by child processes, and then spawns ffmpeg and all the processes
 that will read those same pipes.

 ...and that's the solution I'm using now.  If the above sentence were in
 the documentation, it would be helpful to users like me.
