我有 LRP 摄像机，它在rtsp://172.16.4.6. 我以前VLC经常看这个流媒体。然后我需要ALPR Daemon用于传入流http://以识别相机捕获的车牌。根据文档中的应该只是http://. 因此，VLC我正在尝试将其转换/转码为正确的格式。什么问题，我不熟悉这个领域，没有时间学习基础。
我安装apache2的ubuntu那个有port 80和http://127.0.0.1地址。然后我尝试使用文档https://wiki.videolan.org/Documentation:Streaming_HowTo/Command_Line_Examples/中的一些方法，然后我尝试了$vlc -I http rtsp://172.16.4.6:554/HighResolutionVideo :sout='#transcode{vcodec=MJPG,vb=800,fps=5}:std{access=http{mime=multipart/x-mixed-repace},mux=mpjpeg,dst=127.0.0.1:80/go.mjpg,delay=0}'
但后来我有这个错误日志：
