I am attempting to batch download a number of videos using ffmpeg. A list of the site addresses and save names is stored in a text file in the following format.

"site",filename.mp4

The code that I have is looping through the file and attempting to download each line by line.

#!/bin/bash

while IFS=, read dl nm
do
 echo $dl
 echo $nm
 /usr/bin/ffmpeg -loglevel error -protocol_whitelist file,http,https,tcp,tls,crypto -i $dl -c copy $nm
done < $1

The expected output is that on each loop ffmpeg would download the file indicated by each line and then proceed to the next iteration of the loop.

Instead, ffmpeg outputs the error message

"site": No such file or directory

When I run the same command directly in the terminal with the site name and save name directly inserted into the command, it works without any issue.

Looking at other posts seemingly related to this I have tried appending

< /dev/null

to the end of the ffmpeg call but it still has the same affect.

There's some issues with your script, in that you're using quotes in the file with download URLs/locations.

Namely, that when you have the file the way you do, $dl becomes "site" and$nm` remains as you'd expect.

In order to do this, you either need to change the file so that the site download locations don't have quotes, and then you need to set quotes around $dl in the script.

So you'd end up with this:

input file list:

site,foobar.baz

Script:

#!/bin/bash

while IFS=, read dl nm
do
 echo $dl
 echo $nm
 /usr/bin/ffmpeg -loglevel error -protocol_whitelist file,http,https,tcp,tls,crypto -i "$dl" -c copy $nm
done < $1

You might also want to wrap $nm in quotes as well in case you have a filename that has spaces in it, but that's your decision or not.
