ubuntu - 无法通过 vlc 连接到 rtsp 流

Question

我有网络摄像头。当我访问这个 url 时

rtsp://192.168.20.100:554/user=admin&password=&channel=1&stream=0.sdp?

在我的浏览器中，它让我可以使用我的标准视频播放器，我可以看到视频。但是当我尝试在 cvlc 中打开它时，我几乎没有错误

$cvlc rtsp://192.168.20.100:554/user=admin&password=&channel=1&stream=0.sdp?

我发现了类似的问题，但是没有答案

Convert RTSP stream to HTTP and stream it with VLC client

Answer 1

rtsp url 非常不常见，特别是带有 ?在最后。

发生的是 '&' 字符被 shell 评估，你的命令被第一个 '&' 截断并且一些进程被 fork ([7] 16585...)

它应该可以转义 '&' 或像这样引用 url:

cvlc "rtsp://192.168.20.100:554/user=admin&password=&channel=1&stream=0.sdp?"

或

cvlc rtsp://192.168.20.100:554/user=admin\&password=\&channel=1\&stream=0.sdp?
