Как я могу форсировать новый сеанс в FFmpeg при подключении к входному потоку RTSP? Я не вижу способа передать информацию заголовка. Вот команда и вывод к вопросу.

Команда:

$ ffmpeg -y -hide_banner -loglevel debug -stimeout 10000000 -rtsp_transport tcp \
  -i rtsp://username:password@192.168.1.100:554/live/477799A3-88A9-45AA-95EC-4CBE3CA1FBA7 \
  -vframes 1 -f null /dev/null
