     * <p>The maximum numbers of different types of output streams

     * that can be configured and used simultaneously by a camera device.</p>

     * <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>

     * <li>processed, uncompressed formats: YCbCr_420_888, YCrCb_420_SP, YV12.</li>

     * </ul>

     *

     * @see CameraCharacteristics#SCALER_AVAILABLE_FORMATS

     * <p>How many output streams can be allocated at

     * the same time for each type of stream</p>

     * <p>Video snapshot with preview callbacks requires 3

     * processed streams (preview, record, app callbacks) and

     * one JPEG stream (snapshot)</p>
