我正在从下面的输入流播放视频文件是我的方法:

public static String getDataSource(InputStream inputStream) throws IOException {
            InputStream stream = inputStream;
            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;
          }

但是点击按钮时会有delay of 3 to 4 seconds来播放视频文件,为什么有人可以帮我解决?

此延迟是由于将数据写入临时文件。而您可以使用ParcelFileDescriptor来避免写入临时文件。您可以使用链接(http://www.mattakis.com/blog/kisg/20090708/broadcasting-video-with-android-without-writing-to-the-file-system)作为参考。
