[FFmpeg-user] how to programitically close a ffplay event

[Jim Shupert, Jr.]

I am suspect that My question here will be judged as to broad or having to
do with a shell script and therefore be dismissed.
But , I am curious for a solution so I will ask anyway.

Any wisdom is welcomed. Thanks in advance.
Yes I realize this is a "hard one" , well-- it has been hard for me. ;)

I wish to loop through a directory of videos and play them in a specific way

( 1-for 5 seconds from the start , 2 then go 1 min deep and play for 5 sec )
my problem is I need to kill ffplay

I am very much able to PLAY in the manner i wish but seem UNABLE  to end a
ffplay event so that it can move forward to the next event.

It seems that ffplay stops at then end of 5 sec and then sits and waits.
If I do a control C in the shell or close the ffplay player only then does
the shell script move on.

You will see where I have tried vatious methods to kill ffplay.

My thought was
play file1 way 1
kill ffplay
play file 1 way 2
kill ffplay
and loop to next file
one thing I wish to populate a var $Myp
with the ffplay process id
I do not seem to be doing that right
Myp=$(ps aux | grep ffplay | grep -v grep | awk '{print $2}')



here is my script

#!/bin/bash
