Android Studio – androidx camera2 video capture with flash

I am looking to use camera2 for image and video capture. I found that for image capture I can use the method .setFlashMode(flash_type) but the video capture object does not have this.

CameraManager camManager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
    String cameraId = null; 
    try {
        cameraId = camManager.getCameraIdList()[0];
        camManager.setTorchMode(cameraId, true);   //Turn ON
    } catch (CameraAccessException e) {
        e.printStackTrace();
    }

I have tried using this method where I would turn on the flash before the video capture but was hit with an error which was due to the camera already being in use.

So, I am wondering, is this even possible in androidx yet?

    I found a solution over at the issue tracker for androidx.camera which seems to work.

    if (flash_type == ImageCapture.FLASH_MODE_ON)
    videoCapture.getCamera().getCameraControl().enableTorch(true);

    Any then do the opposite when stopping the video capture.

    Video capture in CameraX is not yet even an alpha-version public API, so it’s very possible it doesn’t yet support flash control.
