Мне нужен прогресс команды FFmpeg, например, сколько времени осталось или сколько процентов выполнено.

this ffmpeg Progress Bar - Процент кодирования в PHP выполняет работу по работе с аудио и видео, но в моем случае не удалось создать видео из изображений.

аналогично вопрос Может ли ffmpeg отображать индикатор выполнения? в моем случае команда следующая

exec("$FFmpegPath -protocol_whitelist file,http,https,tcp,tls,crypto -f concat -safe 0 -i '$image_txt_file' -vsync vfr -pix_fmt yuv420p -vf 'pad=ceil(iw/2)*2:ceil(ih/2)*2' '$out_vid_name' 1>'output.txt' 2>&1", $output, $return_var);

, а в моем выходном файле это то, что у меня есть

и я всегда получаю это прогресс 0 и последний прогресс 88
