Example 31 with CaptureCallback

use of android.hardware.camera2.CameraCaptureSession.CaptureCallback in project platform_frameworks_base by android.

the class Camera2ReprocessCaptureTest method submitMixedCaptureBurstRequest.

/**
     * Submit a burst request mixed with regular and reprocess requests.
     *
     * @param outputs An array of output surfaces. One output surface will be used in one request
     *                so the length of the array is the number of requests in a burst request.
     * @param inputResults An array of input results. If it's null, all requests are regular
     *                     requests. If an element is null, that element represents a regular
     *                     request. If an element if not null, that element represents a reprocess
     *                     request.
