Mp4 Download causes browser to play file instead of download

Question

In my website I stream users mp4 content. I also allow users to download. However in Chrome it seems to automatically play the file in an internal player instead of download

Answer 1

if you want a cross browser solution

you need a server-side code to download the file

example: I am working on jsp technology, if you can use jsp in your website you can try the following code in the file download.jsp:

<%@ page import="java.io.*, java.lang.*, java.util.*" %>
<%
String filename=request.getParameter("filename");   
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition",
"attachment;filename="+filename);
 %>

<%
/*
 File file = new File(filepath+filename );*/
 String path = getServletContext().getRealPath("/mp4/"+filename); 
 File file = new File(path);
FileInputStream fileIn = new FileInputStream(file);
ServletOutputStream out1 = response.getOutputStream();

byte[] outputByte = new byte[4096];
//copy binary contect to output stream
while(fileIn.read(outputByte, 0, 4096) != -1)
{
    out1.write(outputByte, 0, 4096);
}
fileIn.close();
out1.flush();
out1.close();
 %>

you can put the code above in a file: download.jsp

then in your page links you will use it like:
