Ways to rotate HDMI screen in Android

I am making a media player app for a TVBox running Android 7.1.2. I want to rotate the HDMI output but the box's rotation is locked to landscape so I cannot rotate the app using setRequestedOrientation. The library I use is VLC Android with SurfaceView. I cannot use TextureView because it is so lag and drop FPS.

To rotate the HDMI output, I have tried the following:

https://android.stackexchange.com/questions/117003/allow-rotate-into-portrait-mode-but-do-not-rotate-external-display

So is there any other way I can try to rotate screen orientation of HDMI output? Is there any chance that we can rotate screen by OpenGl ES or native code?

Thank you.

so you are saying that you can't use video-filter=rotate, what about video-filter=transform?

final ArrayList<String> args = new ArrayList<>();
args.add("--video-filter=transform");
args.add("--transform-type=270");

mLibVLC = new LibVLC(context, args);
mMediaPlayer = new MediaPlayer(mLibVLC);
final IVLCVout vlcVout = mMediaPlayer.getVLCVout();
vlcVout.setVideoView(mSurfaceView);
vlcVout.setWindowSize(mSurfaceView.getWidth(), mSurfaceView.getHeight());
