Very simple script to avconvert an entire folder of videos assuming they have an mp4, m4v, mov extension.

avconvert.php

#!/usr/bin/env php
<?php

$raw_videos = __DIR__ . '/raw/';
$converted_videos = __DIR__ . '/converted/';


if (file_exists($raw_videos) and is_dir($raw_videos))
{
  if (!file_exists($converted_videos))
	{
		mkdir($converted_videos);
	}
	foreach (glob($raw_videos . '/*.m*') as $file)
	{
		echo PHP_EOL, '<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>', PHP_EOL, '---> Conversion started for ', basename($file), PHP_EOL;
		$output = $converted_videos . basename($file);
		shell_exec('/usr/bin/avconvert -q -prog --preset Preset1920x1080 --source ' . escapeshellarg($file) . ' --output ' . escapeshellarg($output));
		echo '---> Conversion completed for ', basename($file), PHP_EOL, '<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>', PHP_EOL;
		
	}
}
else
{
	echo PHP_EOL, '<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>';
	echo PHP_EOL, '---->>  Raw folder does not exist!';
	echo PHP_EOL, '<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>', PHP_EOL;
}
