How to run ffmpeg command in PHP

Question

I need to run the ffmpeg command in the PHP.

But php-ffmpeg is no more supports the latest version and out of date.

May i know alternate way to run the ffmpeg command in the webfile (PHP,Javascript,jQuery).

I try the exec() and shell_exec() in the PHP file but gets the blank output.

echo shell_exec("/usr/local/bin/ffmpeg  -i test.mp3  -codec:a libmp3lame -b:a 128k out.mp3");

and

 echo shell_exec("ffmpeg  -i test.mp3  -codec:a libmp3lame -b:a 128k  out.mp3");

@Santa'shelper i try exec() and shell_exec() but blank output is there. will you plz let me know syntax for change mp3 bitrate. so i clear i did'nt go wrong. — PreeT, Mar 06 '15 at 13:30
i am not very good at ffmpeg but it should be look like `exec('ffmpeg -i /path/to/my.mp3 -r 44100 /path/to/target.mp3', $output); var_dump($output);` Warning: i am not pretty sure about the -ar 44100 — Santa's helper, Mar 06 '15 at 14:01

ffmpeg outputs on stderr, so you need to redirect the output. Add 2>&1 to your command line:

echo shell_exec("/usr/local/bin/ffmpeg -i test.mp3 -codec:a libmp3lame -b:a 128k out.mp3 2>&1");

Then you will see the output.

2 points to note here: 1) there must be a space prior to the 2 and 2) you must use double quotes not single – Antony Sep 04 '17 at 14:48

@mwangaben What do you mean by "file" – do you mean you want to run `ffmpeg`? Make sure that you either call the full path to ffmpeg (e.g., `/usr/local/bin/ffmpeg`) or that your `$PATH` in PHP contains the folder where `ffmpeg` is. – slhck Oct 21 '17 at 11:49

use FFMpeg\FFMpeg, you can install with composer: "php-ffmpeg/php-ffmpeg": "0.5.*@dev" (FFMpeg\FFMpeg Git Repository)

Or

use Symfony Process, you can install with composer: "symfony/process" : "~2.0" (Symfony Process Documentation)

Or

use proc_open() function.

FFMpeg\FFMpeg used Symfony Process and Symfony Process used proc_open() function :)

I prefer to use Symfony Process:

require 'vendor/autoload.php';

use Symfony\Component\Process\Process;
$process = new Process('ls -lsa');
$process->run();

This is all overkill and not related to the OP's problem, which is a simple shell redirection issue. – slhck Mar 07 '15 at 09:05

this should not be downvoted. The OP did ask for alternative ways to run ffmpeg from a PHP script, which is what this answers to. – Out of Control Jan 11 '19 at 15:57
Was deciphering how proc_open works, turns out I had Symfony available and this was much cleaner. – Cameron Wilby Jun 20 '21 at 08:43
