Я использую ffmpeg для преобразования потока RTSP в поток RTMP. Затем поток RMTP будет передан в Wowza Streaming Engine. Я понятия не имею, почему он работает очень хорошо на одном сервере, но не работает на другом сервере. Оба сервера находятся в разных сетях, но оба являются Window Server 2012, имеют одинаковую версию ffmpeg, преобразуют один и тот же поток RTSP, но один из них завершается ошибкой с сообщением об ошибке Ошибка при открытии декодера для входного потока # 0: 0: при обработке ввода обнаружены неверные данные
Я использовал команду ffmpeg:
ffmpeg -v debug -r 7 -i "rtsp://rtsp-stream-source-server/someRtspStream" -frame rate 7 -video_size 800x592 -vcodec libx264 -preset veryfast -maxrate 750k -bufsize 1500k -tune zerolatency -g 14 -an -r 7 -f flv rtmp://wowza-server:1935/app/stream1
Я сравниваю оба сообщения отладки ffmpeg в обоих случаях и замечаю следующие различия / поведение:
В случае успеха ffmpeg сначала открывает поток RTSP с использованием UDP, но с тайм-аутом UDP, затем повторяет попытку с TCP.В случае сбоя кажется, что это успешно с UDP и нет необходимости повторять с TCP.
Когда ffmpeg успешно открывает поток RTSP, следующая информация распечатывается для успешного случая

Обратите внимание, что число после «Stream # 0:0» отличается.
- В процессе "Сопоставление потоков" случай сбоя содержит следующие сообщения об ошибках.Затем процесс ffmpeg останавливается:

Есть ли у вас какие-либо идеи для случаев отказа и как я могу устранить неполадки?
Ниже отладочное сообщение для обоих случаев для информации
