Я транслирую камеру mobotix на Youtube Live.
В течение некоторого времени это работает правильно. Затем Youtube сообщает о потоке как "noData". ffmpeg продолжает работать, но Youtube не получает видео.
Проблема с перебоями.
Перезапуск процесса ffmpeg заставляет Youtube снова начать получать поток.
ffmpeg выполняется как служба systemd.
ffmpeg запускается с помощью следующей команды:
ffmpeg -nostdin -f lavfi -i anullsrc -rtsp_transport tcp -thread_queue_size 512 -i "rtsp://@192.168.1.1:554/mobotix.h264" -tune zerolatency -vcodec libx264 -pix_fmt + -c:v copy -c:a aac -strict experimental -f flv rtmp://a.rtmp.youtube.com/live2/
Только журналы показывают: ffmpeg[47357]: [48.0K blob data]
Есть идеи, как это решить? Или улучшите ведение журнала.
Редактировать: Журналы с момента запуска ffmpeg:

Выполнение команды вручную дало мне логи и завершилось, тогда как служба systemd продолжает работать.
