android-camera2

I am currently working with Javacv which makes use of the public void onPreviewFrame(byte[] data, Camera camera) camera function. Since camera is deprecated, I have been looking into camera2 and MediaProjection . Both of these libraries make use of the ImageReader class . Currently I instantiate such an ImageReader with the following code: ImageReader.newInstance(DISPLAY_WIDTH, DISPLAY_HEIGHT, PixelFormat.RGBA_8888, 2); And attach an OnImageAvailableListener like this: private final ImageReader.OnImageAvailableListener mOnImageAvailableListener = new ImageReader.OnImageAvailableListener() {

I want to capture image while recording video using camera2 API. Two separate demos are available. 1. To capture image and 2. To record video I tried to combine them into one app. But confused in many things. Like CameraDevice is single which representation of a single camera connected to an Android device. Different template needed in request. For image : mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW); and for video mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_RECORD); In createCaptureSession method surface of ImageReader is needed and for video MediaRecorder is

I'm trying to modify Google's camera2Basic example code. I removed the <FrameLayout/> containing the "Picture" and "Info" button in an attempt to make the <TextureView/> full screen. However, the preview does not fill the entire screen, there remains a black bar below it.

I noticed this exact same issue before on my Galaxy Note 5 and I believe it had to do with the way they set the aspect ratio - there are

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
