FFMpeg runs on the command line, but not in a PHP script

Question

I use FFMpeg to convert videos, and it works fine from the command line. I use the following command:

ffmpeg -i input.avi -ab 56 -ar 44100 -b 200 -r 15 -s 320x240 -f flv output.flv

However, when I run the command using a PHP script, the output video is not encoded.

exec("ffmpeg -i input.avi -ab 56 -ar 44100 -b 200 -r 15 -s 320x240 -f flv output.flv",$output, $returnvalue);

$returnvalue = 127;

Installed FFMPEG path:

[root@localhost ~]# which ffmpeg

/root/bin/ffmpeg

My Script Path:

www.domainname.com/core/foldername/ffmpeg.php

Please provide me a solution for the same ASAP.

Thank.

The natural way to run ffmpegfrom PHP scripts is something like:

<?php
    echo "Starting ffmpeg...\n\n";
    echo shell_exec("ffmpeg -i input.avi output.avi &");
    echo "Done.\n";
?>

, . , , , , ffmpeg ( "&" ), PHP ffmpeg . , PHP exec(), :

, shell_exec() ​exec(). PHP- .

<?php
    echo "Starting ffmpeg...\n\n";
    echo shell_exec("ffmpeg -i input.avi output.avi >/dev/null 2>/dev/null &");
    echo "Done.\n";
?>

, " > /dev/null" , OUTDUT (stdout) ffmpeg /dev/null ( ) 2 > /dev/null " ERROR (stderr) /dev/null ( ). : " > /dev/null 2 > & 1". , -.

I looked at a solution that helps most of the people I talked about about this in a different thread.

Essentially, your user needs access to public directories.

<?php 
   exec('whoami'); // Gives you the running user; often it www-data
?>

Then change your state ownership to the user whoami.

sudo chown -R www-data:root /var/www
