服務器和客戶端之間的實時視頻流 - 使用Java

Question

這是我正在開發的一個項目的一部分。我有兩個桌面Java應用程序，一個在服務器上運行（具有真實IP），另一個是客戶端。我只想從連接到服務器應用程序的網絡攝像頭流式傳輸實況視頻，然後在客戶端應用程序上播放它。我想從多臺攝像機進行流式傳輸。

我一直在尋找Xuggler，JMF，Red5，VLCj之間的天。我不能從我應該從哪裏開始，因爲我是在編程領域與媒體打交道的新手。

我應該從哪裏開始的任何想法？

在此先感謝

Answer 1

我建議你去與VLCJ，因爲除了視頻直播，你可以給你的應用VLC媒體播放器的所有功能。此外，它適用於Linux，Windows和Mac。如果您可以使用VLC直播您的網絡攝像頭，那麼您可以使用VLCJ做同樣的事情。

有關如何使用它的詳細信息，請參閱VLCJ wiki page。他們在wiki中提供了很多例子。這裏是使用VLCJ的Http Streaming的一個例子。從VLCJ的例子複製。
