在 20.10 中使用 VLC 打开安全摄像头（EZVIZ），命令如下：


    rtsp://192.168.1.200:554
    It fails and the log file says:
    satip error: Failed to setup RTSP session
    satip error: Failed to teardown RTSP session
    ```

nmap shows the device is present:

mplayer works but gives error messages:

Apparently something has changed between 20.10 and 21.10 that is affecting VLC.  I've tried various changes to the input/Codec settings that have been suggested on different websites but no effect.
Any ideas?
Thanks

When I run cvlc --no-one-instance -vv rtsp://192.168.1.200:554 on my desktop it just hangs:
VLC media player 3.0.12 Vetinari (revision 3.0.12-1-0-gd147bb5e7e)

When I run it my laptop, also running ubuntu 21.04, it gives this error message:

答案1

为了使其正常工作，请尝试快速安装。

RTSP 流对我来说在本地也无法工作。根据这篇文章，无法播放任何 rtsp 流 - 在 XUbuntu 和 Debian 中，Debian VLC 版本不支持 RTSP。

以下是快照的说明安装

答案2

尝试从终端以更高的详细程度运行以查看发生了什么：

cvlc --no-one-instance -vv rtsp://...

但你的网址在我看来不太合适。rtsp 网址不应该是这样的格式吗rtsp://host:port/path.sdp？或者你可能搞错了协议，应该是这样的rtp://。

答案3

正如前面提到的，debian\ubuntu vlc 版本不再包含 vlc。

这是一个巨大的开销，但 Nix 包对我来说很有用：

nix-shell -p vlc --command "vlc rtsp://192.168.1.137/ch0_0.h264"

您必须先安装 nix 包管理器： https://nixos.org/download.html#download-nix

答案4

可能有点晚了，但 vlc 的修复，请安装更高版本。我在使用 Linux Mint 21.1（基于 ubuntu 22.04）时也遇到了同样的问题。无法从 LM20（ubuntu 20.04）正常工作的闭路电视摄像机流式传输视频。

下载 ppa：

sudo add-apt-repository ppa:savoury1/ffmpeg4
sudo add-apt-repository ppa:savoury1/vlc3
sudo apt-get update
sudo apt-get install vlc

对我有用，似乎 vlc 3.0.16 坏了，ppa 安装 3.0.18。
