 *
 * <p>If there is a preexisting session, the previous session will be closed
 * automatically. However, app still needs to call {@link ACameraCaptureSession_close} on previous
 * session. Otherwise the resources held by previous session will NOT be freed.</p>
 *
 * <p>The active capture session determines the set of potential output {@link ANativeWindow}s for
 * the camera device for each capture request. A given request may use all
 * or only some of the outputs. Once the ACameraCaptureSession is created, requests can be
 * submitted with {@link ACameraCaptureSession_capture} or
 * {@link ACameraCaptureSession_setRepeatingRequest}.</p>
 *
 * <p>Often the {@link ANativeWindow} used with this method can be obtained from a <a href=
 * "http://developer.android.com/reference/android/view/Surface.html">Surface</a> java object by
 * {@link ANativeWindow_fromSurface} NDK method. Surfaces or ANativeWindow suitable for inclusion as a camera
 * output can be created for various use cases and targets:</p>
 *
 * <ul>
 *
 * <li>For drawing to a
 *   <a href="http://developer.android.com/reference/android/view/SurfaceView.html">SurfaceView</a>:
 *   Once the SurfaceView's Surface is created, set the size
 *   of the Surface with
 *   <a href="http://developer.android.com/reference/android/view/SurfaceHolder.html#setFixedSize(int, int)">
 *    android.view.SurfaceHolder\#setFixedSize</a> to be one of the PRIVATE output sizes
 *   returned by {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}
 *   and then obtain the Surface by calling <a href=
 *   "http://developer.android.com/reference/android/view/SurfaceHolder.html#getSurface()">
 *   android.view.SurfaceHolder\#getSurface</a>. If the size is not set by the application, it will
 *   be rounded to the nearest supported size less than 1080p, by the camera device.</li>
 *
 * <li>For accessing through an OpenGL texture via a <a href=
 *   "http://developer.android.com/reference/android/graphics/SurfaceTexture.html">SurfaceTexture</a>:
 *   Set the size of the SurfaceTexture with <a href=
 *   "http://developer.android.com/reference/android/graphics/SurfaceTexture.html#setDefaultBufferSize(int, int)">
 *   setDefaultBufferSize</a> to be one of the PRIVATE output sizes
 *   returned by {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}
 *   before creating a Surface from the SurfaceTexture with <a href=
 *   "http://developer.android.com/reference/android/view/Surface.html#Surface(android.graphics.SurfaceTexture)">
 *   Surface\#Surface(SurfaceTextrue)</a>. If the size is not set by the application, it will be set to be the
 *   smallest supported size less than 1080p, by the camera device.</li>
 *
 * <li>For recording with <a href=
 *     "http://developer.android.com/reference/android/media/MediaCodec.html">
 *     MediaCodec</a>: Call
 *   <a href=
 *     "http://developer.android.com/reference/android/media/MediaCodec.html#createInputSurface()">
 *     android.media.MediaCodec\#createInputSurface</a> after configuring
 *   the media codec to use one of the PRIVATE output sizes
 *   returned by {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}.
 *   </li>
 *
 * <li>For recording with <a href=
 *    "http://developer.android.com/reference/android/media/MediaRecorder.html">
 *    MediaRecorder</a>: Call
 *   <a href="http://developer.android.com/reference/android/media/MediaRecorder.html#getSurface()">
 *    android.media.MediaRecorder\#getSurface</a> after configuring the media recorder to use
 *   one of the PRIVATE output sizes returned by
 *   {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}, or configuring it to use one of the supported
 *   <a href="http://developer.android.com/reference/android/media/CamcorderProfile.html">
 *    CamcorderProfiles</a>.</li>
 *
 * <li>For access to RAW, uncompressed YUV, or compressed JPEG data in the application: Create an
 *   {@link AImageReader} object using the {@link AImageReader_new} method with one of the supported
 *   output formats given by {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}. Then obtain a
 *   ANativeWindow from it with {@link AImageReader_getWindow}.
 *   If the AImageReader size is not set to a supported size, it will be rounded to a supported
 *   size less than 1080p by the camera device.
 *   </li>
 *
 * </ul>
 *
 * <p>The camera device will query each ANativeWindow's size and formats upon this
 * call, so they must be set to a valid setting at this time.</p>
 *
 * <p>It can take several hundred milliseconds for the session's configuration to complete,
 * since camera hardware may need to be powered on or reconfigured.</p>
 *
 * <p>If a prior ACameraCaptureSession already exists when this method is called, the previous
 * session will no longer be able to accept new capture requests and will be closed. Any
 * in-progress capture requests made on the prior session will be completed before it's closed.
 * To minimize the transition time,
 * the ACameraCaptureSession_abortCaptures method can be used to discard the remaining
 * requests for the prior capture session before a new one is created. Note that once the new
 * session is created, the old one can no longer have its captures aborted.</p>
 *
 * <p>Using larger resolution outputs, or more outputs, can result in slower
 * output rate from the device.</p>
 *
 * <p>Configuring a session with an empty list will close the current session, if
 * any. This can be used to release the current session's target surfaces for another use.</p>
 *
 * <p>While any of the sizes from {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS} can be used when
 * a single output stream is configured, a given camera device may not be able to support all
 * combination of sizes, formats, and targets when multiple outputs are configured at once.  The
 * tables below list the maximum guaranteed resolutions for combinations of streams and targets,
 * given the capabilities of the camera device.</p>
 *
 * <p>If an application tries to create a session using a set of targets that exceed the limits
 * described in the below tables, one of three possibilities may occur. First, the session may
 * be successfully created and work normally. Second, the session may be successfully created,
 * but the camera device won't meet the frame rate guarantees as described in
 * {@link ACAMERA_SCALER_AVAILABLE_MIN_FRAME_DURATIONS}. Or third, if the output set
 * cannot be used at all, session creation will fail entirely, with
 * {@link ACAMERA_ERROR_STREAM_CONFIGURE_FAIL} being returned.</p>
 *
 * <p>For the type column `PRIV` refers to output format {@link AIMAGE_FORMAT_PRIVATE},
 * `YUV` refers to output format {@link AIMAGE_FORMAT_YUV_420_888},
 * `JPEG` refers to output format {@link AIMAGE_FORMAT_JPEG},
 * and `RAW` refers to output format {@link AIMAGE_FORMAT_RAW16}
 *
 *
 * <p>For the maximum size column, `PREVIEW` refers to the best size match to the
 * device's screen resolution, or to 1080p `(1920x1080)`, whichever is
 * smaller. `RECORD` refers to the camera device's maximum supported recording resolution,
 * as determined by <a href="http://developer.android.com/reference/android/media/CamcorderProfile.html">
 * android.media.CamcorderProfiles</a>. And `MAXIMUM` refers to the
 * camera device's maximum output resolution for that format or target from
 * {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS}.</p>
 *
 * <p>To use these tables, determine the number and the formats/targets of outputs needed, and
 * find the row(s) of the table with those targets. The sizes indicate the maximum set of sizes
 * that can be used; it is guaranteed that for those targets, the listed sizes and anything
 * smaller from the list given by {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS} can be
 * successfully used to create a session.  For example, if a row indicates that a 8 megapixel
 * (MP) YUV_420_888 output can be used together with a 2 MP `PRIV` output, then a session
 * can be created with targets `[8 MP YUV, 2 MP PRIV]` or targets `[2 MP YUV, 2 MP PRIV]`;
 * but a session with targets `[8 MP YUV, 4 MP PRIV]`, targets `[4 MP YUV, 4 MP PRIV]`,
 * or targets `[8 MP PRIV, 2 MP YUV]` would not be guaranteed to work, unless
 * some other row of the table lists such a combination.</p>
 *
