How to constantly take pictures in Android Camera2?

I'm working on an Android project where I have to repeatedly take photos and process them with a facial recognition API. I realize that I have to use camera2's methods (either setRepeatingRequest or setRepeatingBurst), but these methods only take a photo once every 5 seconds or so. I was wondering how I would change this to take a picture at least twice every second without lag. Is this even possible? If not, what would you recommend I use to do this?

private final ImageReader.OnImageAvailableListener mOnImageAvailableListener
            = new ImageReader.OnImageAvailableListener() {

        @Override
        public void onImageAvailable(ImageReader reader) {
            try (Image image = reader.acquireNextImage()) {
                Image.Plane[] planes = image.getPlanes();
                if (planes.length > 0) {
                    ByteBuffer buffer = planes[0].getBuffer();
                    byte[] data = new byte[buffer.remaining()];
                    buffer.get(data);
                    mCallback.onPictureTaken(data);
                }
            }
        }

    };

This may help you,here is the use of Camera2.
