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。
