> ffmpeg -re -i very_long_intro.mp4 -i <event_source> -re -i 
> very_long_outro.mp4
>     -filter_complex   '[0:v][0:a] [1:v][1:a] [2:v][2:a] 
> concat=n=3:v=1:a=1 [v] [a];
>                                   [v] 
> zmq=b=tcp\\:\\/\\/127.0.0.1\\:5555  [v_out]'
>     -map '[v_out]' -map '[a]'  <output>
>
> When you you want to start the live event, issue in another window:
> echo "Parsed_concat_0 next" | zmqsend  -b tcp://127.0.0.1:5555
>
> When you want to end the live session:
> echo "Parsed_concat_0 next" | zmqsend  -b tcp://127.0.0.1:5555

>
> Please review this patch. Thank you in advance.
