Estou usando o ffmpeg para converter um fluxo RTSP em um fluxo RTMP. O fluxo de RMTP será então alimentado no Wowza Streaming Engine. Eu não tenho idéias porque funciona muito bem em um servidor, mas falha em outro servidor. Ambos os servidores estão em redes diferentes, mas ambos são Windows Server 2012, têm a mesma versão ffmpeg, convertem um mesmo fluxo RTSP, mas um falha com a mensagem de erro Erro ao abrir o decodificador para fluxo de entrada # 0: 0: Dados inválidos encontrados ao processar entrada
O comando ffmpeg que eu usei é:
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
Eu comparo as duas mensagens de debug do ffmpeg em ambos os casos e observo as diferenças / comportamentos a seguir:
Para o caso de sucesso, o ffmpeg primeiro abre o fluxo RTSP usando UDP, mas o UDP timeout, então ele tenta novamente com o TCP. Para o caso de falha, parece que ele é bem sucedido com o UDP e não é necessário repetir com o TCP. / p>
Quando o ffmpeg abre com êxito um fluxo RTSP, as seguintes informações são impressas para o caso de sucesso

Você tem alguma ideia para os casos de falha e como posso solucionar o problema?
Abaixo está a mensagem de depuração para ambos os casos para a informação

Dando um passo para trás, estou querendo saber se existe uma alternativa ao uso do FFmpeg que evitaria esse problema. Eu provavelmente estou sentindo falta de algo que é óbvio para você, mas você poderia apenas ingerir o streaming RTSP diretamente com o Wowza Streaming Engine e eliminar a necessidade de FFmpeg neste fluxo de trabalho?
