用Media Player 播放 mpg檔案

huanghuang發表於2006-10-24
先說明的是此mpg檔案,如果不安裝一個Media Player Filter包，Media Player 是不能播放的，所以在每臺機器上都安裝了Media Player Filter包。

1.頁面上播放mpg檔案，如果向下面這樣，能正常播放，（filename 引數直接寫檔名稱<param name="Filename" value="d://clip.mpg">）

/show/test.jsp 如下：


<%@ page language="java"%>
<%@ page import="java.io.*"%>

<%
response.setContentType("bin");

int maxBufferLength = 81920;
byte[] b = new byte[maxBufferLength];
InputStream fs = new FileInputStream("d://Clip.mpg"); // 不能正常播放
//InputStream fs = new FileInputStream("d://speedis.avi");
// b = new byte[fs.available()];
b = new byte[maxBufferLength];
DataOutputStream outTmp = new DataOutputStream(response.getOutputStream());
int len;
try {

if (fs != null) {
while ((len = fs.read(b)) > 0) {
outTmp.write(b, 0, len); //這出的錯
}
} catch (Exception e) {
e.printStackTrace();

}

}finally{
outTmp.close();
}

%>
第2種方法出現的異常是：
ClientAbortException: java.net.SocketException: Connection reset by peer: socket write error
問： 我要的是第2種方法，因為需要從資料庫中讀出檔案內容。不知道第2種方法為什麼不正常播放。
