Symfony 进程 - 找不到命令

Question

我正在尝试使用 Symfony 进程组件执行 ffmpeg 命令，但命令未被处理。我究竟做错了什么？我收到错误

The command "'ffmpeg -i [...........]' failed. Exit Code: 127(Command not found)"

<?php 
$info = pathinfo($file);
$dir = "{$info['dirname']}/{$info['filename']}";
File::makeDirectory($dir, 0755, true)
$process = new Process(["ffmpeg -i {$info['basename']} -codec copy -map 0 -f segment -segment_list {$dir}/playlist.m3u8 -segment_list_flags +live -segment_time 10 {$dir}/{$info['filename']}_%02d.ts"]);
$process->setWorkingDirectory($info['dirname']);
$process->start();
if (!$process->isSuccessful()) {
    throw new ProcessFailedException($process);
}
echo $process->getOutput();
?>

您必须将每个参数放在数组的单独元素中，例如：

$process = new Process([
    "ffmpeg",
    "-i",
    "{$info['basename']}",
    "-codec",
    "copy",
    "-map",
    "0",
    "-f",
    "segment",
    "-segment_list",
    "{$dir}/playlist.m3u8",
    "-segment_list_flags",
    "+live",
    "-segment_time",
    "10",
    "{$dir}/{$info['filename']}_%02d.ts",
]);

我认为你应该：

使用$process->run()代替$process->start()
或通过 $process->start()
