StreamComfigurationMap.GetOutputStallDuration(int, Size).Īctual performance varies from device to device, though Android provides some Streams that meet the minimum FPS determined by If you configure the target surfaces correctly, this code will produce only tRepeatingRequest(combinedRequest.build(), null, null) frames so there is no need to set up a callback for the capture request has its own callback that you have to listen to in order to retrieve the In this simple case, the SurfaceView gets updated automatically. Link the Surface targets with the combined requestĬombinedRequest.addTarget(previewSurface)ĬombinedRequest.addTarget(imReaderSurface) Val requestTemplate = CameraDevice.TEMPLATE_PREVIEW TEMPLATE_STILL_CAPTURE, and for a steady frame rate use TEMPLATE_RECORD because it is optimized for low latency for high-quality images, use You will use the preview capture template for the combined streams from CameraCaptureSession.StateCallback Stream for camera preview and another stream for image processing: val session: CameraCaptureSession =.

The following code snippet illustrates how to set up a camera session with one Multiple camera streams can be combined into a single Resources like CPU, GPU, and DSP might be able to take advantage of theĬapabilities, but resources like memory will grow linearly. Multiplied when doing parallel stream or pipeline processing. There is a non-trivial performance cost when processing frames, and the cost is BothĬameraX and Camera2 work on Android 5.0 (API level 21) and higher. Recommend using the CameraX Jetpack library except when your useĬase requires access to specific features available only in Camera2. Computational photography: one stream for preview, another for face/scene.Barcode scanning: one stream for preview, another for barcode detection.Video recording: one stream for preview, another being encoded and saved into.Some cases, different streams even require a different frame resolution or pixel A camera application can use more than one stream of frames simultaneously.
