DEPTH 16 format produces 0 values

Is DEPTH16 in Camera2 API ready to use? or we are supposed to use ARCore for depth detection? My use case is not to render depth data/image continuously on screen, but to capture a JPEG image and it's depth when user tap on capture button in a shot.

I created a capture request of TEMPLATE_PREVIEW / TEMPLATE_STILL_PICTURES for target image reader of Image Format DEPTH16 as following.
```
imageReader = ImageReader.newInstance(
240, 180, ImageFormat.DEPTH16, IMAGE_BUFFER_SIZE)
```

```
val captureRequest = camera.createCaptureRequest(
CameraDevice.TEMPLATE_PREVIEW).apply {
addTarget(depthImageReader.surface)
}
```

captureRequest.set(CaptureRequest.JPEG_ORIENTATION, 0)
val fpsRange: Range = Range(15, 30)
captureRequest.set(CaptureRequest.CONTROL_AE_TARGET_FPS_RANGE, fpsRange)
session.capture(captureRequest.build(), null, null)

```
imageReader.setOnImageAvailableListener({ reader ->
val image = reader.acquireNextImage()

```
on this image , with session.capture, the depth samples are all 0. if I replace it with session.setRepeatingRequest(captureRequest.build(), null, null), the first frames are still all 0 values, after some movement, the later frames has a a lot of 0, 8192, and very large values such as 17524 (17m which is not correct?), along with some random range.

I've tested https://medium.com/swlh/working-with-the-3d-camera-on-the-samsung-s10-5g-4782336783c , however the first frames are 0 as well

Commencez par examiner la documentation de la Camera2 API pour ImageFormat.DEPTH16, ImageReader et les requêtes de capture. Reproduisez le problème avec la configuration DEPTH16 240×180 présentée, à la fois avec session.capture et setRepeatingRequest, puis déterminez si les échantillons nuls et hors limites indiquent un comportement non pris en charge par l’appareil ou une erreur de l’application.
