服务器和客户端之间的实时视频流 - 使用 Java

Question

这是我正在进行的项目的一部分。我有两个桌面 java 应用程序，一个在服务器上运行（具有真实 IP），另一个是客户端。我只想从连接到服务器应用程序的网络摄像头流式传输实时视频，并在客户端应用程序上播放。我想从多个摄像头进行流式传输。

我一直在寻找 Xuggler、JMF、Red5、VLCj 之间的日子。我只是不知道应该从哪里开始，因为我是在编程中处理媒体的新手。

我应该从哪里开始的任何想法？

提前致谢

我建议您使用 VLCJ，因为除了实时视频流之外，您还可以在应用程序中使用 VLC 媒体播放器的所有功能。此外，它适用于 Linux、Windows 和 Mac。如果你可以用 VLC 直播你的网络摄像头，那么你可以用 VLCJ 做同样的事情。

有关如何使用它的详细信息，请参阅 VLCJ wiki page。他们在 wiki 中提供了许多示例。这是使用 VLCJ 的 Http Streaming 的示例。复制自 VLCJ 示例。
