如何从RTSP制作HTTP流

Question

我有在rtsp://172.16.4.6中产生RTSP流的LRP相机。我使用VLC来查看此流媒体。然后，我需要使用ALPR Daemon传递码流http://以识别摄像头拍摄的牌照。根据文档中应该只有http://。所以使用VLC我试图转换/转码为适当的格式。有什么问题，我不熟悉这个领域，没有时间学习基础知识。

我在apache2上安装了ubuntu那有port 80和http://127.0.0.1的地址。然后我试图用一些方法从文档https://wiki.videolan.org/Documentation:Streaming_HowTo/Command_Line_Examples/，然后我试图$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}'

但后来我有这样的错误日志：

[00007f5fb0001268] core access out error: socket bind error: Permission denied 
[00007f5fb0001268] core access out error: cannot create socket(s) for HTTP host

我认为你必须在repace一个错字，试试这个：

--sout #transcode{vcodec=MJPG,venc=ffmpeg{strict=1}}:standard{access=http{mime=multipart/x-mixed-replace;boundary=--7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:80/go.mjpg}
