Bash script does not continue to read the next line of file

Question

I have a shell script that saves the output of a command that is executed to a CSV file. It reads the command it has to execute from a shell script which is in this format:

Answer 1

I just had the same problem.

I believe ffmpeg is responsible for this behaviour.

My solution for this problem:

1) Call ffmpeg with an "&" at the end of your ffmpeg command line

2) Since now the skript will not wait till completion of the ffmpeg process, we have to prevent our script from starting several ffmpeg processes. We achieve this goal by delaying the loop pass while there is at least one running ffmpeg process.

#!/bin/bash

cat FileList.txt |
while read VideoFile; do
     &
    FFMPEGStillRunning="true"
    while [ "$FFMPEGStillRunning" = "true" ]; do
        Process=$(ps -C ffmpeg | grep -o -e "ffmpeg" )
        if [ -n "$Process" ]; then
            FFMPEGStillRunning="true"
        else
            FFMPEGStillRunning="false"
        fi 
        sleep 2s
    done
done
