type CaptureRequest C.ACaptureRequest
*
- ACaptureRequest is an opaque type that contains settings and output targets needed to capture
- a single image from camera device. *
- <p>ACaptureRequest contains the configuration for the capture hardware (sensor, lens, flash),
- the processing pipeline, the control algorithms, and the output buffers. Also
- contains the list of target {@link ANativeWindow}s to send image data to for this
- capture.</p> *
- <p>ACaptureRequest is created by {@link ACameraDevice_createCaptureRequest}. *
- <p>ACaptureRequest is given to {@link ACameraCaptureSession_capture} or
- {@link ACameraCaptureSession_setRepeatingRequest} to capture images from a camera.</p> *
- <p>Each request can specify a different subset of target {@link ANativeWindow}s for the
- camera to send the captured data to. All the {@link ANativeWindow}s used in a request must
- be part of the {@link ANativeWindow} list given to the last call to
- {@link ACameraDevice_createCaptureSession}, when the request is submitted to the
- session.</p> *
- <p>For example, a request meant for repeating preview might only include the
- {@link ANativeWindow} for the preview SurfaceView or SurfaceTexture, while a
- high-resolution still capture would also include a {@link ANativeWindow} from a
- {@link AImageReader} configured for high-resolution JPEG images.</p> *

- device, since once the camera device is emptied, the first new request has to make it through

func (*CaptureSession) Close ¶
func (session *CaptureSession) Close()
*
- Close this capture session. *
- <p>Closing a session frees up the target output Surfaces of the session for reuse with either
- a new session, or to other APIs that can draw to Surfaces.</p> *
- <p>Note that creating a new capture session with {@link ACameraDevice_createCaptureSession}
- will close any existing capture session automatically, and call the older session listener's
- {@link ACameraCaptureSession_stateCallbacks#onClosed} callback. Using
- {@link ACameraDevice_createCaptureSession} directly without closing is the recommended approach
- for quickly switching to a new session, since unchanged target outputs can be reused more
- efficiently.</p> *
- <p>After a session is closed and before {@link ACameraCaptureSession_stateCallbacks#onClosed}
- is called, all methods invoked on the session will return {@link ACAMERA_ERROR_SESSION_CLOSED},
- and any repeating requests are stopped (as if {@link ACameraCaptureSession_stopRepeating} was
- called). However, any in-progress capture requests submitted to the session will be completed as
- normal; once all captures have completed and the session has been torn down,
- {@link ACameraCaptureSession_stateCallbacks#onClosed} callback will be called and the seesion
- will be removed from memory.</p> *

func (*Device) CreateCaptureSession ¶
func (device *Device) CreateCaptureSession(outputs *CaptureSessionOutputContainer, cb CaptureSessionStateCallbacks) (*CaptureSession, error)
*
- Create a new camera capture session by providing the target output set of {@link ANativeWindow}
- to the camera device. *
- <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 efficient YUV processing with <a href=
- "http://developer.android.com/reference/android/renderscript/package-summary.html">
- RenderScript</a>:
- Create a RenderScript
- <a href="http://developer.android.com/reference/android/renderscript/Allocation.html">
- Allocation</a> with a supported YUV
- type, the IO_INPUT flag, and one of the YUV output sizes returned by
- {@link ACAMERA_SCALER_AVAILABLE_STREAM_CONFIGURATIONS},
- Then obtain the Surface with
- <a href="http://developer.android.com/reference/android/renderscript/Allocation.html#getSurface()">
- Allocation#getSurface}</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> *
