我正在尝试重新流式传输RTSP Feed并转换为h264。
我正在使用以下命令行:
C:\Users\Martyn>ffmpeg -re -i rtsp://192.168.2.207/VideoInput/1/mpeg4/ -preset ultrafast -vcodec libx264 -tune zerolatency -b:v 900k -f rtsp udp://192.168.0.2:1234
我得到的输出是:
C:\Users\Martyn>ffmpeg -re -i rtsp://192.168.2.207/VideoInput/1/mpeg4/ -preset u
ltrafast -vcodec libx264 -tune zerolatency -b:v 900k -f rtsp udp://192.168.0.2:1

我如何知道这是否是流媒体?当我尝试连接到udp://192.168.0.2:1234时没有任何反应。
