如何将视频从URI转换为字节[] [英] How to convert video from URI to byte[]

问题描述

我已经捕获了视频，并获得了该视频的URI.

I have captured video and I get a URI of that video.

如何将URI指向的内容加载到 byte [] 结构中?

How to load the content pointed to by that URI into byte[] structure?

推荐答案

看看

• ByteArrayOutputStream ，
• FileInputStream 和
• File(URI uri) .

代码示例:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
FileInputStream fis = new FileInputStream(new File(yourUri));

byte[] buf = new byte[1024];
int n;
while (-1 != (n = fis.read(buf)))
    baos.write(buf, 0, n);

byte[] videoBytes = baos.toByteArray();
