RTSP stream 不正确

Question

我正在尝试从我的网络摄像头仅使用 stream 和 RTSP 视频 stream 并在同一台机器上的 VM（Docker 容器）内使用提要。

这是我正在使用的命令行参数：

_vlcInstance = new LibVLCSharp.Shared.LibVLC("--dshow-vdev=Microsoft LifeCam Cinema(TM)", "--no-audio", "--verbose=2", "--no-spu");
_player = new MediaPlayer(_vlcInstance);
_media.AddOption(":sout=#transcode{vcodec=h264,scale=Auto,acodec=none,scodec=none}:rtp{dst=127.0.0.1,port=5004,mux=ts,sap,name=cam,sdp=rtsp://127.0.0.1:5004/cam} :no-sout-all :sout-keep");
_player.Play(_media);

当我启动这段代码时，我可以从容器内连接，但“播放”事件处理程序永远不会执行。 以下是日志：

Answer 1

这实际上是一个复杂的故障排除。 最终修复是在服务器端（我创建流的地方）。 我需要使用以下链：

:sout=#transcode{vcodec=h264,venc=any,vb=1000,acodec=none}:rtp{dst=192.168.1.100,port=8554,sdp=rtsp://:8554/cam.sdp}

（IP应该是机器的实际LAN IP。不是127.0.0.1）。

Answer 2

我认为您错误地使用了 127.0.0.1。 即使在同一台机器上，每个容器都有自己的 127.0.0.1，与主机的 localhost 不同。

我不太了解您的设置和端口重定向，但假设您有两个容器 A（生产者）和 B（消费者），您必须访问rtsp://A:5004/ （您可以使用和我一样的容器名称）

Answer 3

阅读您的日志后，您似乎可以连接到 RTSP 协议，但 RTP 协议失败。

我会尝试两件事：

• stream 与rtp{dst=172.19.0.1
• 使用--rtsp-tcp播放 stream （如果有效，这是 UDP 和您的 VM 配置的问题）
