Я пытаюсь сохранить аудио (или видео) канал на локальный, используя FFmpeg. Вот команда и аргументы, которые я использую.
ffmpeg -i http://7359.live.streamtheworld.com:80/CONTINENTALAAC_SC -vn -ar 22050 -acodec flac -ss 0 -t 6000 test1.flac
Затем я повторяю это в Bash, но у меня есть совпадение между концом одного файла и следующим.
Есть ли способ получать этот канал каждые 10 минут?
Это вывод оболочки:
ffmpeg -i http://7359.live.streamtheworld.com:80/CONTINENTALAAC_SC -vn -ar 22050 -acodec flac -ss 0 -t 6 test1.flac
