Running ffmpeg in loop seems to change reading from file
Hi everyone,
I am fairly new to shell scripting. I want to read in numbers from a file (one number per line). This works perfectly fine
and yields the correct output:
If I however run a ffmpeg command in the loop
the output changes (I ommit the ffmpeg output and just give the echo command output):
If I add two spaces in the txt-file I read in, such as
the echo command returns the right numbers again - for some reason, the ffmpeg commands seems to result in the skipping of the first two characters in the new line.
If I put an additional for-loop around the while loop to loop over several files such as in
The first line of every file is read in correctly, but for all subsequent lines, the first two characters are skipped. Does anybody have any idea what is going on? I am very grateful for any hint.

winff
WINFF(1)WINFF(1)NAME
winff - video and audio batch converter using ffmpeg
SYNOPSIS
winff
DESCRIPTION
This manual page documents briefly the winff command. This manual page was written for the Debian(TM) distribution because the original
program does not have a manual page. Instead, it has documentation pdf format; see below.
WinFF is a graphical user interface for the command line video converter ffmpeg. It runs ffmpeg from the command line. So, you just pick
your files and it does the rest.
WinFF doesn't actually convert any video files. It just runs ffmpeg. Therefore, It will convert any video file that ffmpeg will convert.
Conversely, if ffmpeg will not convert the file, then WinFF will not either.
SEE ALSO
For more details, you should have a look at the pdf manual, available at /usr/share/doc/winff/winff.pdf
