Oi eu sou capaz de transmitir vídeo com sucesso da minha câmera IP com VLC usando o URL: rtsp: //192.168.0.6: 554 / cam / realmonitor
Ao tentar usar o FFMPEG, ele está falhando com os seguintes erros: Anexei comms bem-sucedidos do VLC e também a conversação das comunicações do FFMPEG com falha.
Como posso fazer o FFMPEG se comportar como o VLC para capturar com êxito o fluxo?
Agradeço antecipadamente por qualquer ajuda
