JCVideoCapture
==============

.. java:package:: at.jumpch.sdk
   :noindex:

.. java:type:: @SuppressWarnings public class JCVideoCapture implements JCVideoCaptureInterface, Camera.PreviewCallback

   The JCVideoCapture class implements \ :java:ref:`JCVideoCaptureInterface`\  to access the default Android camera video capture.

Constructors
------------
JCVideoCapture
^^^^^^^^^^^^^^

.. java:constructor:: public JCVideoCapture()
   :outertype: JCVideoCapture

   Creates a new JCVideoCapture object to access a particular hardware camera and provide frames for streaming.

Methods
-------
enableHD
^^^^^^^^

.. java:method:: public boolean enableHD(boolean enable)
   :outertype: JCVideoCapture

   Enable HD or SD when capturing the video

   :param enable: boolean to determine HD(ex. 1280x720) or SD(ex. 640x480) quality.
   :return: \ ``true``\  if successfully enabled HD, \ ``false``\  otherwise

onPreviewFrame
^^^^^^^^^^^^^^

.. java:method:: @Override public void onPreviewFrame(byte[] data, Camera camera)
   :outertype: JCVideoCapture

   Called as preview frames are displayed. This callback is invoked on the event thread \ :java:ref:`android.hardware.Camera.open(int)`\  was called from.

   If using the \ :java:ref:`android.graphics.ImageFormat.YV12`\  format, refer to the equations in \ :java:ref:`Camera.Parameters.setPreviewFormat`\  for the arrangement of the pixel data in the preview callback buffers.

   :param data: the contents of the preview frame in the format defined by \ :java:ref:`android.graphics.ImageFormat`\ , which can be queried with \ :java:ref:`android.hardware.Camera.Parameters.getPreviewFormat()`\ . If \ :java:ref:`android.hardware.Camera.Parameters.setPreviewFormat(int)`\  is never called, the default will be the YCbCr_420_SP (NV21) format.
   :param camera: the Camera service object.

resumeCapture
^^^^^^^^^^^^^

.. java:method:: public boolean resumeCapture()
   :outertype: JCVideoCapture

   Resume video capture. Generally restart the capture thread if stopped.

   :return: \ ``true``\  if success, \ ``false``\  otherwise

selectCamera
^^^^^^^^^^^^

.. java:method:: public boolean selectCamera(int cameraId)
   :outertype: JCVideoCapture

   Select the camera id. For example front or back camera. This can be an empty method in a custom stream.

   :param cameraId: Integer to determine if front or back camera should be used. See \ :java:ref:`android.hardware.Camera.open`\
   :return: \ ``true``\  if camera selection was successful, \ ``false``\  otherwise

startCapture
^^^^^^^^^^^^

.. java:method:: public boolean startCapture(int width, int height, int framerate, Context applicationContext, JCVideoCaptureCallback cb)
   :outertype: JCVideoCapture

   Start a thread to provide video frames to the system. Parameters are suggestions and can be safely ignored when implementing the method.

   :param width: Video frame width
   :param height: Video frame height
   :param framerate: Frames per second
   :param applicationContext: Application context provided in \ :java:ref:`JCClient`\
   :param cb: Callback object used to provide video frame to the system
   :return: \ ``true``\  if successful, \ ``false``\  otherwise

stopCapture
^^^^^^^^^^^

.. java:method:: public synchronized boolean stopCapture()
   :outertype: JCVideoCapture

   Stop the capture thread. Called when app goes into the background.

   :return: \ ``true``\  if successful, \ ``false``\  otherwise

switchCamera
^^^^^^^^^^^^

.. java:method:: public boolean switchCamera()
   :outertype: JCVideoCapture

   Switch the camera. Used to toggle between front and back camera.

   :return: \ ``true``\  if successful, \ ``false``\  otherwise
