服务器和客户端之间的实时视频流-使用Java

Question

这是我正在从事的项目的一部分。我有两个桌面Java应用程序，一个运行在服务器上（具有真实IP），另一个运行在客户端上。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，然后在客户端应用程序上播放它。我想从多个摄像机进行流式传输。

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，因为我刚接触编程中的媒体。

我从哪里开始有什么想法？

提前致谢

Answer 1

我建议您使用VLCJ，因为除了实时视频流之外，您还可以获得应用程序可用的VLC媒体播放器的所有功能。此外，它可用于Linux，Windows和Mac。如果可以使用VLC实时直播网络摄像头，则可以使用VLCJ进行相同的处理。

有关如何使用它的详细信息，请参考VLCJ
Wiki页面。他们在Wiki中提供了许多示例。这是使用VLCJ的Http流的示例。从VLCJ示例复制。
