ffmepg - когда я запускаю второй экземпляр, первый останавливается

Я пытаюсь преобразовать поток видео на мой сервер rtmp с помощью ffmpeg. Я использую Node-Media-Server для получения моего потока rtmp.

Моя версия ffmpeg: 

ffmpeg version N-93447-g5252d594a1 Copyright (c) 2000-2019 the FFmpeg developers

Моя проблема в том, что когда я запускаю этот cmd, он работает хорошо :

ffmpeg -i http://server_ip:8080/19871 -bsf:a aac_adtstoasc -c copy -f flv rtmp://localhost/live/test

Но когда я запускаю другой экземпляр ffmpeg в другой оболочке, первое убийство и второе запускаются хорошо:

ffmpeg -i http://server_ip:8080/12222 -bsf:a aac_adtstoasc -c copy -f flv rtmp://localhost/live/test2

Первый вывод: 

> ffmpeg -i http://server_ip:8080/19871 -bsf:a aac_adtstoasc  -c copy -f flv rtmp://localhost/live/test

Как запустить 2 экземпляра потока ffmpeg?

Заранее благодарен за ответы.
