Как использовать ffmpeg -t при использовании живого источника YouTube с youtube-dl?

Я хотел загрузить поток YouTube с https://www.youtube.com/watch?v=0R0T0mQmx7I, добавив количество времени, которое мне нравится. Поэтому, используя youtube-dl, я получаю все его форматы:

$ youtube-dl --list-formats https://www.youtube.com/watch?v=0R0T0mQmx7I [youtube] 0R0T0mQmx7I: Downloading webpage [youtube] 0R0T0mQmx7I: Downloading video info webpage [youtube] 0R0T0mQmx7I: Extracting video information [youtube] 0R0T0mQmx7I: Downloading MPD manifest [info] Available formats for 0R0T0mQmx7I: format code extension resolution note 140 m4a audio only DASH audio 144k, m4a_dash container, mp4a.40.2@128k 160 mp4 256x144 144p 124k, avc1.42c00b, 30fps, video only 133 mp4 426x240 240p 258k, avc1.4d4015, 30fps, video only 134 mp4 640x360 360p 646k, avc1.4d401e, 30fps, video only 135 mp4 854x480 480p 1171k, avc1.4d401f, 30fps, video only 136 mp4 1280x720 720p 2326k, avc1.4d401f, 30fps, video only (best) 

Я понял, что аудио и видео находятся в разных форматах, поэтому это не будет простым. Поэтому я использую следующую команду для извлечения аудио и видео:

$ ffmpeg -i $(youtube-dl -f 136 -g https://www.youtube.com/watch?v=0R0T0mQmx7I) -i $(youtube-dl -f 140 -g https://www.youtube.com/watch?v=0R0T0mQmx7I) -c:v copy -c:a aac -strict experimental -t 00:02:00 output.mp4 

Но это не работает. Просто записывает до 5 секунд и все. Я пытался переместить параметр "-t 00:02:00" в разных местах и ​​не работает. Кто-нибудь знает решение? Спасибо !!
