<?php

exec("/usr/local/bin/ffmpeg -sameq -i /home/xxx/public_html/xxx/video/full.mp4 -itsoffet 6 -i /home/xxx/public_html/xxx/sounds/names/george.mp3 /home/xxx/public_html/xxx/upload/sample.mpg");


?>

Thank you a lot!

Answer 1

Firstly, you have a typo in your command: -itsoffet should be -itsoffset.

Secondly, it seems there’s a bug affecting -itsoffset.

Take a look at these identical/similar questions:

• Add audio (with an offset) to video with FFMPEG
• delay audio with ffmpeg
• Add multiple audio files to video at specific points using FFMPEG
