在 PHP 中使用 ffmpeg exec 找不到文件和压缩

Question

I'm trying to compress files with ffmpeg but despite having the correct file path it cannot find the file:

I'm using this code here:

echo $ypath;
exec("ffmpeg -i ".$ypath." -vf 'scale=iw/3:ih/3' ".$prevPath ." 2>&1", $error);
foreach($error as $next) {
    echo "<br>".$next;
}

And get this result:

../data/mydirectory/buffer/1610997353779_D012&ForestDescend.mp4
sh: 1: ForestDescend.mp4: not found

What's the problem, why can't it find the file in question. I'm 100% sure the path is correct because I'm using it further above the code to convert images who are in the same directory.

How can I solve this issue?

Answer 1

The ampersand ( & ) in the filename is probably causing the issue. A simple way around this is to wrap the $ypath value in quotes:

exec('ffmpeg -i "'.$ypath.'" -vf "scale=iw/3:ih/3" "'.$prevPath .'" 2>&1', $error);

Combine this withescapeshellarg() if your filenames might contain quotes or other special characters.
