服务器和客户端之间的实时视频流 - 使用Java

问题描述

这是我正在开展的一个项目的一部分。我有两个桌面java应用程序，一个在服务器上运行（它有真正的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况视频，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之间的天。我只是不能从我应该开始，因为我是新的处理媒体在编程中。

从这里开始的任何想法？

提前感谢

$ b $我建议你使用VLCJ，因为除了实时视频流，你获得所有的VLC媒体播放器的功能可用于您的应用程序。此外，它可用于Linux，Windows和Mac。如果你可以使用VLC实时流式传输网络摄像头，那么你可以对VLCJ进行同样的操作。

有关详情，请参阅VLCJ 如何使用它。他们在wiki中提供了很多例子。这里是使用VLCJ的Http Streaming的示例。从VLCJ示例复制。

this is part of a project I am working on. I have two desktop java application , one runs on the server (which has real IP), and the other is the client. I just want to stream a live video from a webcam connected to the server application , and play it on the client application. I want to do this streaming from more than one camera.

I have been looking searching for days between Xuggler, JMF, Red5, VLCj. I just can't figure from where I should start as I am new to dealing with media in programming.

Any ideas from where I should start with this ?

Thanks in advance

解决方案

I suggest you to go with VLCJ, because in addition to live video streaming, you get all features of VLC media player available to your application. Also, it is available for Linux,Windows, and Mac. If you can live stream your webcam with VLC, then you can do the same with VLCJ.

Refer VLCJ wiki page for details on how to use it. They provided many examples in the wiki. Here is an example of Http Streaming using VLCJ. Copied from VLCJ examples.
