Script not working with newer FFMPEG version

[daphatty]

Looks like changes to FFMPEG have rendered this script inert. Attempting to run this script against any file with a basic command ./script_name.sh "/path/to/file" results in a failed attempt.

I modified the script with set -x and found the following error

+ msg='Correct number of black segments found'
+ finalarray=("${breaktimes[@]}")

Additionally, using the -c=c or -c=r flag results in this error.

ffmpeg action (-c) not set properly.

I am currently running FFMPEG Version 7:3.4.8-0ubuntu0.2
