FFMPEG image capture only executes partially on cron
17 mai 2022, par C. ArdayfioI have the following shell script :


DailyScript.sh


#!/bin/sh
now="/Users/mydir/Downloads/LIDOPRO/Captures/$(date +'%Y_%m_%d_%I_%M_%p').jpg"
"/Users/mydir/Downloads/LIDOPRO/ffmpeg" -ss 0.5 -f avfoundation -framerate 30 -i "0" -frames:v 1 -t 1 "$now"



It produces an image through my FaceTime camera when I run the script manually in shell, as follows :


$ /Users/mydir/Downloads/LIDOPRO/DailyScript.sh



And the output I get is the following

Everything works perfectly fine and the image is output.


So, I created a cron job to run the script automatically, as follows :

However, this cronjob does not actually work. No photo is produced and the script seems to execute, but only partially :

Does anyone know how to resolve this issue ? I'd like the image to be produced.
