我的 rtsp 流网址是

rtsp://192.17.3.2/user=admin&password=&channel=2&stream=0.sdp?

该网址在 Windows 中使用 VLC 工作。

在 Ubuntu 中，我使用了 gst-launch，如下所示。

gst-launch-1.0 --gst-debug=rtspsrc:5 rtspsrc location=rtsp://192.17.3.2/user=admin&password=&channel=2&stream=0.sdp? ! rtph264depay ! queue ! nvv4l2decoder ! queue ! nvvideoconvert ! nveglglessink

可能是什么问题？完整的错误是

xavier@xavier-desktop:~$ gst-launch-1.0 --gst-debug=rtspsrc:5 rtspsrc location=rtsp://192.17.3.2/user=admin&password=&channel=2&stream=0.sdp? ! rtph264depay ! queue ! nvv4l2decoder ! queue ! nvvideoconvert ! nveglglessink

该错误代码意味着一个法律问题：

451 因法律原因不可用

超文本传输​​协议 (HTTP) 451 Unavailable For Legal Reasons 客户端错误响应代码表示用户请求的资源由于法律原因不可用，例如已对其采取法律行动的网页。

但是，鉴于 URL 在 Windows 上有效，这可能会产生误导，并且可能只是 Ubuntu 在“&”符号处拆分 URL。

您可以将 url 用单引号或双引号括起来，然后再试一次，如果这是应该解决它的原因。
