[FFmpeg-user] tee pseudo muxer instance -> pipe to ncat

the following works with a note that piping takes precedence irregardless
of a named pipe position in the tee muxer command
in other words if there is a connection on port 9000 all 3 streams will be

-f tee
| nc64 -L -p 9000

interestingly, if  [f=mpegts:onfail=ignore]pipe:1| is used, doesn't change
the behavior. It is good if that is desired.

However, I am now thinking of intermediate tee:

something like -f tee
| tee > (nc64 -L -p 9000 )

but I still have no test results, which I will report.
