camera2

Can I use camera preview and flashlight at the same time in Android Camera2 API? When I try use CameraManager.setTorchMode(String cameraId, boolean enabled) it's work fine when camera is not opened. But when Camera is open and I try setTorchMode I receive this exception: CameraService: setTorchMode: torch mode of camera 0 is not available because camera is in use The error is indicating that the camera in question, is already in use. You need to set the FLASH_MODE and CONTROL_AE_MODE accordingly. mPreviewRequestBuilder.set(CaptureRequest.FLASH_MODE, CaptureRequest.FLASH_MODE_OFF);

I'm trying to record a video using Android Camera2 API. I'm trying to crop video as a square by setting the SCALER_CROP_REGION in the request builder. I'm using the following code but it doesn't seem to work mCameraDevice.createCaptureSession(surfaces, new CameraCaptureSession.StateCallback() { @Override public void onConfigured( CameraCaptureSession cameraCaptureSession) { mCaptureSession = cameraCaptureSession; try { mIsRecording = true; /////****** this where i'm setting the coping mZoom = getZoomRect(); mPreviewRequestBuilder.set(CaptureRequest.SCALER_CROP_REGION, mZoom); /////////********

I'm creating a custom camera capturing videos with the new camera2 API. My code is strongly inspired from the code provided by Google here .

For some reason, when I click on the "switch/swap camera" button for the first time , it brings be to the front camera as it should, BUT everytime I click again, the switch/swap doesn't work anymore: the preview (on the front camera) fades a little bit, like if something is

I want to implement a app to record 60 fps with fixed exposure time. As device I have the Google Pixel. Since its native camera app can do 60 fps and it has hardware level LEVEL_3, I thought this won't be a problem but I can't get it working. With getSupportedPreviewFpsRange() (from camera api) I get ranges [15, 15], [24, 24], [7, 30], [30, 30] and with getHighSpeedVideoFpsRangesFor (from camera2 api) I get ranges [30, 120], [120, 120], [30, 240], [240, 240], [240, 240] . When I set [60, 60] to CONTROL_AE_TARGET_FPS_RANGE I get error "Fps range [60, 60] in the request is not a supported high
