How do i make sure all child_process are killed when the parent process is killed. I have something like the below one.
Even when the node process is kill i see that FFMPEG continues to run and the out.avi is generated. How can i stop FFMPEG from running after the node process exits.
var args = "ffmpeg -i in.avi out.avi"
child_process.exec(args , function(err, stdout,stderr){});
child_process.exec(args , function(err, stdout,stderr){});
You need to listen for the process exit event and kill the child processes then. This should work for you:
var args = "ffmpeg -i in.avi out.avi"
var a = child_process.exec(args , function(err, stdout,stderr){});
var b = child_process.exec(args , function(err, stdout,stderr){});
process.on('exit', function () {
a.kill();
b.kill();
});
