Merge vids:
Let,s create the list first. Here is an example and let us call the list fileList.txt. In this example, both the files are in the home directory. each line starts with the keyword file and contains the path of the file within single quotes.
$ cat fileList.txt
file '/home/file1.mp4'
file '/home/file1.mp4'
Now, you can concatenate them.
