Eino-Ville Talvala | f3621f3 | 2014-08-26 14:53:39 -0700 | [diff] [blame] | 256 | * <p>While any of the sizes from {@link StreamConfigurationMap#getOutputSizes} can be used when |
| 257 | * a single output stream is configured, a given camera device may not be able to support all |
| 258 | * combination of sizes, formats, and targets when multiple outputs are configured at once. The |
| 259 | * tables below list the maximum guaranteed resolutions for combinations of streams and targets, |
| 260 | * given the capabilities of the camera device.</p> |
| 261 | * |
| 262 | * <p>If an application tries to create a session using a set of targets that exceed the limits |
| 263 | * described in the below tables, one of three possibilities may occur. First, the session may |
| 264 | * be successfully created and work normally. Second, the session may be successfully created, |
| 265 | * but the camera device won't meet the frame rate guarantees as described in |
| 266 | * {@link StreamConfigurationMap#getOutputMinFrameDuration}. Or third, if the output set |
| 267 | * cannot be used at all, session creation will fail entirely, with |
| 268 | * {@link CameraCaptureSession.StateListener#onConfigureFailed} being invoked.</p> |
| 269 | * |
| 270 | * <p>For the type column, {@code PRIV} refers to any target whose available sizes are found |
| 271 | * using {@link StreamConfigurationMap#getOutputSizes(Class)} with no direct application-visible |
| 272 | * format, {@code YUV} refers to a target Surface using the |
| 273 | * {@link android.graphics.ImageFormat#YUV_420_888} format, {@code JPEG} refers to the |
| 274 | * {@link android.graphics.ImageFormat#JPEG} format, and {@code RAW} refers to the |
| 275 | * {@link android.graphics.ImageFormat#RAW_SENSOR} format.</p> |
| 276 | * |
| 277 | * <p>For the maximum size column, {@code PREVIEW} refers to the best size match to the |
| 278 | * device's screen resolution, or to 1080p ({@code 1920x1080}), whichever is |
| 279 | * smaller. {@code RECORD} refers to the camera device's maximum supported recording resolution, |
| 280 | * as determined by {@link android.media.CamcorderProfile}. And {@code MAXIMUM} refers to the |
| 281 | * camera device's maximum output resolution for that format or target from |
| 282 | * {@link StreamConfigurationMap#getOutputSizes}.</p> |
| 283 | * |
| 284 | * <p>To use these tables, determine the number and the formats/targets of outputs needed, and |
| 285 | * find the row(s) of the table with those targets. The sizes indicate the maximum set of sizes |
| 286 | * that can be used; it is guaranteed that for those targets, the listed sizes and anything |
| 287 | * smaller from the list given by {@link StreamConfigurationMap#getOutputSizes} can be |
| 288 | * successfully used to create a session. For example, if a row indicates that a 8 megapixel |
| 289 | * (MP) YUV_420_888 output can be used together with a 2 MP {@code PRIV} output, then a session |
| 290 | * can be created with targets {@code [8 MP YUV, 2 MP PRIV]} or targets {@code [2 MP YUV, 2 MP |
| 291 | * PRIV]}; but a session with targets {@code [8 MP YUV, 4 MP PRIV]}, targets {@code [4 MP YUV, 4 |
| 292 | * MP PRIV]}, or targets {@code [8 MP PRIV, 2 MP YUV]} would not be guaranteed to work, unless |
| 293 | * some other row of the table lists such a combination.</p> |

Zhijun He | b1300e3 | 2015-05-28 12:51:52 -0700 | [diff] [blame] | 638 | * <p>Create a new constrained high speed capture session.</p> |
| 639 | * |
| 640 | * <p>The application can use normal capture session (created via {@link #createCaptureSession}) |
| 641 | * for high speed capture if the desired high speed FPS ranges are advertised by |
| 642 | * {@link CameraCharacteristics#CONTROL_AE_AVAILABLE_TARGET_FPS_RANGES}, in which case all API |
| 643 | * semantics associated with normal capture sessions applies.</p> |
| 644 | * |
| 645 | * <p>The method creates a specialized capture session that is only targeted at high speed |
| 646 | * video recording (>=120fps) use case if the camera device supports high speed video |
| 647 | * capability (i.e., {@link CameraCharacteristics#REQUEST_AVAILABLE_CAPABILITIES} contains |
| 648 | * {@link CameraMetadata#REQUEST_AVAILABLE_CAPABILITIES_CONSTRAINED_HIGH_SPEED_VIDEO}). |
| 649 | * Therefore, it has special characteristics compared with a normal capture session:</p> |
| 650 | * |
| 651 | * <ul> |
| 652 | * |
| 653 | * <li>In addition to the output target Surface requirements specified by the |
| 654 | * {@link #createCaptureSession} method, an active high speed capture session will support up |
| 655 | * to 2 output Surfaces, though the application might choose to configure just one Surface |
| 656 | * (e.g., preview only). All Surfaces must be either video encoder surfaces (acquired by |
| 657 | * {@link android.media.MediaRecorder#getSurface} or |
| 658 | * {@link android.media.MediaCodec#createInputSurface}) or preview surfaces (obtained from |
| 659 | * {@link android.view.SurfaceView}, {@link android.graphics.SurfaceTexture} via |
| 660 | * {@link android.view.Surface#Surface(android.graphics.SurfaceTexture)}). The Surface sizes |
| 661 | * must be one of the sizes reported by {@link StreamConfigurationMap#getHighSpeedVideoSizes}. |
| 662 | * When multiple Surfaces are configured, their size must be same.</li> |
| 663 | * |
| 664 | * <li>An active high speed capture session only accepts request lists created via |
Eino-Ville Talvala | 639fffe | 2015-06-30 10:34:48 -0700 | [diff] [blame] | 665 | * {@link CameraConstrainedHighSpeedCaptureSession#createHighSpeedRequestList}, and the |
| 666 | * request list can only be submitted to this session via |
| 667 | * {@link CameraCaptureSession#captureBurst captureBurst}, or |
Zhijun He | b1300e3 | 2015-05-28 12:51:52 -0700 | [diff] [blame] | 668 | * {@link CameraCaptureSession#setRepeatingBurst setRepeatingBurst}.</li> |
| 669 | * |
| 670 | * <li>The FPS ranges being requested to this session must be selected from |
| 671 | * {@link StreamConfigurationMap#getHighSpeedVideoFpsRangesFor}. The application can still use |
| 672 | * {@link CaptureRequest#CONTROL_AE_TARGET_FPS_RANGE} to control the desired FPS range. |
| 673 | * Switching to an FPS range that has different |
| 674 | * {@link android.util.Range#getUpper() maximum FPS} may trigger some camera device |
| 675 | * reconfigurations, which may introduce extra latency. It is recommended that the |
| 676 | * application avoids unnecessary maximum target FPS changes as much as possible during high |
| 677 | * speed streaming.</li> |
| 678 | * |
| 679 | * <li>For the request lists submitted to this session, the camera device will override the |
| 680 | * {@link CaptureRequest#CONTROL_MODE control mode}, auto-exposure (AE), auto-white balance |
| 681 | * (AWB) and auto-focus (AF) to {@link CameraMetadata#CONTROL_MODE_AUTO}, |
| 682 | * {@link CameraMetadata#CONTROL_AE_MODE_ON}, {@link CameraMetadata#CONTROL_AWB_MODE_AUTO} |
| 683 | * and {@link CameraMetadata#CONTROL_AF_MODE_CONTINUOUS_VIDEO}, respectively. All |
| 684 | * post-processing block mode controls will be overridden to be FAST. Therefore, no manual |
| 685 | * control of capture and post-processing parameters is possible. Beside these, only a subset |
| 686 | * of controls will work, see |
| 687 | * {@link CameraMetadata#REQUEST_AVAILABLE_CAPABILITIES_CONSTRAINED_HIGH_SPEED_VIDEO} for |
| 688 | * more details.</li> |
| 689 | * |
| 690 | * </ul> |
| 691 | * |
| 692 | * @param outputs The new set of Surfaces that should be made available as |
| 693 | * targets for captured high speed image data. |
| 694 | * @param callback The callback to notify about the status of the new capture session. |
