-     * <p>This is a 3 element tuple that contains the max number of output simultaneous
-     * streams for raw sensor, processed (and uncompressed), and JPEG formats respectively.
-     * For example, if max raw sensor format output stream number is 1, max YUV streams
-     * number is 3, and max JPEG stream number is 2, then this tuple should be <code>(1, 3, 2)</code>.</p>
-     * <p>This lists the upper bound of the number of output streams supported by
-     * the camera device. Using more streams simultaneously may require more hardware and
-     * CPU resources that will consume more power. The image format for a output stream can
-     * be any supported format provided by {@link CameraCharacteristics#SCALER_AVAILABLE_FORMATS android.scaler.availableFormats}. The formats
-     * defined in {@link CameraCharacteristics#SCALER_AVAILABLE_FORMATS android.scaler.availableFormats} can be catergorized into the 3 stream types
-     * as below:</p>
-     * <ul>
-     * <li>JPEG-compressed format: BLOB.</li>
-     * <li>Raw formats: RAW_SENSOR and RAW_OPAQUE.</li>
