Java 将输入流传递到视频视图

我有输入流，我需要将其作为视频视图传递：

但它说的是OutOfMemoryError

这是我的密码：

//to convert input stream to string
public static String convertStreamToString(InputStream is) throws Exception {
        BufferedReader reader = new BufferedReader(new InputStreamReader(is));
        StringBuilder sb = new StringBuilder();
        String line = null;

        while ((line = reader.readLine()) != null) {
            sb.append(line);
        }

        is.close();

        return sb.toString();
    }

//passing that string to video view
String total = convertStreamToString(inputStream);
Uri uri = Uri.parse(total);
videoHolder.setVideoURI(uri);

如何实现这一点

这是堆栈跟踪

好的，我已经自己解决了，但是在视频文件开始之前有3到4秒的延迟

希望它能帮助一些人：

public static String getDataSource(String path) throws IOException {
      if (!URLUtil.isNetworkUrl(path)) {
            return path;
        } else {
           URL url = new URL(path);
           URLConnection cn = url.openConnection();
           cn.connect();
            InputStream stream = cn.getInputStream();
            if (stream == null)
                throw new RuntimeException("stream is null");
            File temp = File.createTempFile("mediaplayertmp", "dat");
            temp.deleteOnExit();
            String tempPath = temp.getAbsolutePath();
            FileOutputStream out = new FileOutputStream(temp);
            byte buf[] = new byte[128];
            do {
                int numread = stream.read(buf);
                if (numread <= 0)
                    break;
                out.write(buf, 0, numread);
            } while (true);
            try {
                stream.close();
                out.close();
            } catch (IOException ex) {
              //  Log.e(TAG, "error: " + ex.getMessage(), ex);
            }
            return tempPath;
        }
    }

公共静态字符串getDataSource（字符串路径）引发IOException{
如果（！URLUtil.isNetworkUrl（路径））{
返回路径；
}否则{
URL=新URL（路径）；
URLConnection cn=url.openConnection（）；
cn.connect（）；
InputStream=cn.getInputStream（）；
if（流==null）
抛出新的RuntimeException（“流为null”）；
File temp=File.createTempFile（“mediaplayertmp”、“dat”）；
temp.deleteOnExit（）；
字符串tempPath=temp.getAbsolutePath（）；
FileOutputStream out=新的FileOutputStream（临时）；
字节buf[]=新字节[128]；
做{
int numread=stream.read（buf）；
if（numread）请发布整个堆栈跟踪。您是将视频文件强制转换为字符串对象吗？：D还是重新措辞-在字符串对象中加载视频文件？@commonware我发布了堆栈跟踪您从何处获取此流？请记住
setVideoURI（）
获取URI，例如
文件：//
或
http://
路径。输入流是classLoader.getResourceAsStream，
