public class JCVideoCapture implements JCVideoCaptureInterface, Camera.PreviewCallback¶: The JCVideoCapture class implements JCVideoCaptureInterface to access the default Android camera video capture.

Constructors¶

JCVideoCapture¶

public JCVideoCapture()¶: Creates a new JCVideoCapture object to access a particular hardware camera and provide frames for streaming.

Methods¶

enableHD¶

public boolean enableHD(boolean enable)¶

Enable HD or SD when capturing the video

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

onPreviewFrame¶

public void onPreviewFrame(byte[] data, Camera camera)¶

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

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

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

Returns:	`true` if camera selection was successful, `false` otherwise

startCapture¶

public boolean startCapture(int width, int height, int framerate, Context applicationContext, JCVideoCaptureCallback cb)¶

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

Parameters:	width – Video frame width height – Video frame height framerate – Frames per second applicationContext – Application context provided in `JCClient` cb – Callback object used to provide video frame to the system
Returns:	`true` if successful, `false` otherwise

stopCapture¶

public synchronized boolean stopCapture()¶

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