Я хочу запускать процессы ffmpeg из заданий laravel, но не слишком много сразу.Я просто не могу понять это правильно.Независимо от того, что я установил для $ process_limit - он запускается только по одному, и между ними есть большие задержки.Возможно, я использую public $ timeout неправильно.Возможно retryUntil ().Я не знаю.
