Hello there,

I install PHP-FFMpeg on aapanel with apache/LAMP(PHP 8.0)

Installed ffmpeg using "sudo apt install ffmpeg"
then check with "which ffmpeg" and "which ffprobe"
ffmpeg path= /usr/bin/ffmpeg
ffprobe path= /usr/bin/ffprobe

I run this command "composer require php-ffmpeg/php-ffmpeg" -> "/www/wwwroot/mydomain/"

I upload video.mp4 -> "/www/wwwroot/mydomain/"

and create index.php to test, here the code:

<?php

require 'vendor/autoload.php';

$ffmpeg = FFMpeg\FFMpeg::create(array(
    'ffmpeg.binaries'  => '/usr/bin/ffmpeg',
    'ffprobe.binaries' => '/usr/bin/ffprobe',
    'timeout'          => 3600, // The timeout for the underlying process
    'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
));

$video = $ffmpeg->open('video.mp4');
$video
    ->save(new FFMpeg\Format\Video\WebM(), 'export-webm.webm');

and i receive this error:

解决方案是什么？

去 php.ini 把 proc_open 打开，比如LNMP安装的环境有一行是禁用的功能，其中默认就有proc_open，删掉就行了
