Please help me to find out...

Zoom photo preview

Trying to add slider zoomer to Camera for photos.
Added to CameraController:

float getCurrentZoom();
void setCurrentZoom(float zoom);
float getMaxZoom();

Added to Camera1Controller

@Override
    public float getCurrentZoom() {
        return cameraManager.getCurrentZoom();
    }
    @Override
    public float getMaxZoom() {
        return cameraManager.getMaxZoom();
    }
    @Override
    public void setCurrentZoom(float zoom) {
        cameraManager.setCurrentZoom(zoom);
    }

Added to Camera2Controller

      @Override
    public float getCurrentZoom() {
        return camera2Manager.getCurrentZoom();
    }
    @Override
    public float getMaxZoom() {
        return camera2Manager.getMaxZoom();
    }
    @Override
    public void setCurrentZoom(float zoom) {
        camera2Manager.setCurrentZoom(zoom);
    }

Added to CameraManager

    float getCurrentZoom();
    void setCurrentZoom(float zoom);
    float getMaxZoom();

Added to AnncaCameraActivity

protected float getCurrentZoom() {
        return getCameraController().getCurrentZoom();
    }
    protected float getMaxZoom() {
        return getCameraController().getMaxZoom();
    }
    protected void setCurrentZoom(float zoom) {
        getCameraController().setCurrentZoom(zoom);
    }

I'm getting value of it by max zoom of camera1

Camera.Parameters parameter = camera.getParameters();
        if(parameter.isZoomSupported()) {
            return parameter.getMaxZoom();
        }

and camera2

(manager.getCameraCharacteristics(this.currentCameraId).get(CameraCharacteristics.SCALER_AVAILABLE_MAX_DIGITAL_ZOOM))*10

SeekBar impementation:

minZoom = getMinZoom();
        maxZoom = getMaxZoom() - 1;
        final int step = 1;
        seekBarBottom.setMax(Math.round(maxZoom - minZoom));
        seekBarBottom.setOnSeekBarChangeListener(
                new SeekBar.OnSeekBarChangeListener()
                {
                    @Override
                    public void onStopTrackingTouch(SeekBar seekBar) {}
                    @Override
                    public void onStartTrackingTouch(SeekBar seekBar) {}
                    @Override
                    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {                        
                        setCurrentZoom(Math.round(minZoom + (progress * step)));
                    }
                }
        );

I've added to Camera1Manager

public void setCurrentZoom(float zoom) {
        Camera.Parameters parameter = camera.getParameters();
        if(getCurrentZoom() < getMaxZoom()) {
            parameter.setZoom(Math.round(zoom));
            camera.setParameters(parameter);
        }
    }

Works fine.

I've added to Camera2Manager

protected int zoomLevel = 1;
public void setCurrentZoom(float zoomLevel) {
        try {
            CameraCharacteristics characteristics = manager.getCameraCharacteristics(this.currentCameraId);
            float maxZoom = (characteristics.get(CameraCharacteristics.SCALER_AVAILABLE_MAX_DIGITAL_ZOOM))*10;
            Rect m = characteristics.get(CameraCharacteristics.SENSOR_INFO_ACTIVE_ARRAY_SIZE);
            if((zoomLevel <= maxZoom) && (zoomLevel > 1)) {
                int minW = (int) (m.width() / maxZoom);
                int minH = (int) (m.height() / maxZoom);
                int difW = m.width() - minW;
                int difH = m.height() - minH;
                int cropW = difW / 100 * (int) zoomLevel;
                int cropH = difH / 100 * (int) zoomLevel;
                cropW -= cropW & 3;
                cropH -= cropH & 3;
                Rect zoom = new Rect(cropW, cropH, m.width() - cropW, m.height() - cropH);
                try {
                    previewRequestBuilder.set(CaptureRequest.SCALER_CROP_REGION, zoom);
                    captureSession.capture(previewRequestBuilder.build(), captureCallback, backgroundHandler);
                } catch (Exception e) {
                    Log.e(TAG, "Error updating preview: ", e);
                }
                this.zoomLevel = (int) zoomLevel;
            }
        } catch (Exception e) {
            Log.e(TAG, "Error during camera init");
        }
    }

It zooms but immediately returns to normal state. Is there some listener that changes its state back?

Not correct sizing of Camera2

about this part of code in Camera2Manager

if (configurationProvider.getMediaAction() == AnncaConfiguration.MEDIA_ACTION_PHOTO
                    || configurationProvider.getMediaAction() == AnncaConfiguration.MEDIA_ACTION_UNSPECIFIED) {
                if (windowSize.getHeight() * windowSize.getWidth() > photoSize.getWidth() * photoSize.getHeight()) {
                    previewSize = CameraHelper.
                            getOptimalPreviewSize(Size.fromArray2(map.getOutputSizes(SurfaceTexture.class)), photoSize.getWidth(), photoSize.getHeight());
                } else {
                    previewSize = CameraHelper.
                            getOptimalPreviewSize(Size.fromArray2(map.getOutputSizes(SurfaceTexture.class)), windowSize.getWidth(), windowSize.getHeight());
                }
                if (previewSize == null)
                    previewSize = CameraHelper.chooseOptimalSize(Size.fromArray2(map.getOutputSizes(SurfaceTexture.class)), windowSize.getWidth(), windowSize.getHeight(), photoSize);

            } else {
                if (windowSize.getHeight() * windowSize.getWidth() > videoSize.getWidth() * videoSize.getHeight()) {
                    previewSize = CameraHelper.getOptimalPreviewSize(Size.fromArray2(map.getOutputSizes(SurfaceTexture.class)), videoSize.getWidth(), videoSize.getHeight());
                } else {
                    previewSize = CameraHelper.getOptimalPreviewSize(Size.fromArray2(map.getOutputSizes(SurfaceTexture.class)), windowSize.getWidth(), windowSize.getHeight());
                }

                if (previewSize == null)
                    previewSize = CameraHelper.getSizeWithClosestRatio(Size.fromArray2(map.getOutputSizes(SurfaceTexture.class)), videoSize.getWidth(), videoSize.getHeight());
            }

It cuts the left and right parts of picture that will be created.
It will be better to live only

if (configurationProvider.getMediaAction() == AnncaConfiguration.MEDIA_ACTION_PHOTO
                    || configurationProvider.getMediaAction() == AnncaConfiguration.MEDIA_ACTION_UNSPECIFIED) {
                previewSize = CameraHelper.
                            getOptimalPreviewSize(Size.fromArray2(map.getOutputSizes(SurfaceTexture.class)), photoSize.getWidth(), photoSize.getHeight());

            } else {
                previewSize = CameraHelper.getOptimalPreviewSize(Size.fromArray2(map.getOutputSizes(SurfaceTexture.class)), videoSize.getWidth(), videoSize.getHeight());
            }

Hi!How to differentiate type of action within onActivityResult?

HI!
this is not issue, i think it already exist.
How can I understand Photo or Video was captured? (of course I can check uri extension but...)

And also can I set Video settings without 'setMediaAction'? I mean that by default Photo mode will be shown , but when I select Video mode - restrictions will be applied. is it possible?

Preview Size

Привет, никак не могу понять как задать камере previewSize не переписывая библиотечный мотод. Есть какой нибудь способ?

Is it possible to open front camera if back camera is not available?

Currently there is error:

Foucs on touch

Awesome time working on your library, great work really.
But it would be so much useful if a feature of focus on touch is added in the library.
I tried myself but could not get a way around to successfully implement the feature.

how to maintain the ratio of video image?

Hi, I apologize in advance if my language is not good :)

As Figures 1 and 2:

The audio play but the images do not move

After exporting to mp4, you open mp4 file in File Explorer : the audio plays but the images do not move, after a period of time the audio stops playing and the picture starts to move. Display time is also not normal (video about 10s but time show about >2h).

Demo:
https://chatnhanh.blob.core.windows.net/chat/5a1e55d59b53e9324027f49e/158852/89313aeb-2124-4832-9543-5622c67154b7/vid_2018_07_13_17_08_33.mp4

Code:
AnncaConfiguration.Builder builder = new AnncaConfiguration.Builder (context, CAPTURE_MEDIA);
builder.setMediaQuality (AnncaConfiguration.MEDIA_QUALITY_LOW);
builder.setMediaResultBehaviour (AnncaConfiguration.PREVIEW);
builder.setVideoDuration (2 * 60 * 1000);
new Annca (builder.build ()) launchCamera ();

Thanks!

Error during preparing MediaRecorder: setAudioSource failed.

I'm trying to use Annca in my own app.
Taking photo work well. When I try to take video I ear sound, button change in stop but no timer showed and getting following error:
E/Camera1Manager: Error during preparing MediaRecorder: setAudioSource failed.

Samsung SM-J500FN running android 5.1.1.
I'm launching Annca with:
AnncaConfiguration.Builder builder = new AnncaConfiguration.Builder(this, CAPTURE_MEDIA);
builder.setMediaAction(AnncaConfiguration.MEDIA_ACTION_UNSPECIFIED);
new Annca(builder.build()).launchCamera();

Edit: sorry RECORD_AUDIO permission was missing

Is there any way to disable video mode?

Flash not working by default settings FLASH_MODE_ON

Hi,

Thanks for the the nice library.
We're facing issue with Flash when taking photo.
We set Flash mode ON, as below code. But not see Flash when taking photo.
AnncaConfiguration.Builder builder = new AnncaConfiguration.Builder(activity, CAPTURE_MEDIA); builder.setFlashMode(AnncaConfiguration.FLASH_MODE_ON); builder.setMediaResultBehaviour(AnncaConfiguration.CONTINUE); new Annca(builder.build()).launchCamera();

Flash working only when click on Flash button on Screen to turn it ON. Then It works only for first photo. And then it wont flash again later even its kept still ON, unless we click on button again to turn it ON.

I try to analyze the code to fix it, but couldn't able fix it. Could you please let us know how to fix this issue.

Thank you.

In camera1 it returns correct value of picture orientation to rotate. But when I'm using camera2, this function always returns 0. Try it. Maybe you should set orientation property or rotate bitmap before it's saving in camera2.

That's why I'm using the function:

private int getAdditionalCamera2Rotation() {
        if(isCamera2) {
            int angle;
            if(degrees == 0) {
                angle = 90;
            } else if(degrees == 270) {
                angle = 180;
            } else if(degrees == 180) {
                angle = 270;
            } else {
                angle = 0;
            }
            return angle;
        } else {
            return 0;
        }
    }

Provide custom locales

Hi there,
first - thanks for providing this library to everyone it'll save me a lot of time.

I am using your library and currently it provides english and I assume danish locales only. Is there any way to change/add locales e.g. for the different textViews within activity_preview or for the dialog you create within onSettingsClick(...)?
Currently I get your library via Gradle and actually I don't want to import it manually and modify it myself.

It would be nice to hear from you.

Camera open error API level 25

Trying to open camera on Nexus 5X (Android 7.1.1 API 25)

E/Camera2Controller: onCameraOpenError

add autofocus on view on click -- require camera instance ,but cant find where to start

hi awesome library , but current autofocus take too long on samsung tested on s6 , tried adding the autofocus on code using a a viewOnclickListener , on the main baseAnncaActivity , but it i can grab Camera instance , and also i realise it uses surfaceview and base camera for camera2,camera1 currently this code is for camera1 , where i assume Camera instance is available

code is as follows

private Camera mCamera;
mIsAutoFocusing =false; // can be used as a flag , autofocus is already implemented
 
  @Override // onviewClicklistener
    public void onClick(View view) {
            if (mCamera == null || mIsAutoFocusing) return;
            try {
                mIsAutoFocusing = true;
                mCamera.cancelAutoFocus();
                mCamera.autoFocus(new Camera.AutoFocusCallback() {
                    @Override
                    public void onAutoFocus(boolean success, Camera camera) {
                        mIsAutoFocusing = false;
                        if (!success)
                            Toast.makeText(getActivity(), "Unable to auto-focus!", Toast.LENGTH_SHORT).show();
                    }
                });
            } catch (Throwable t) {
                t.printStackTrace();
            }
        } else {
            super.onClick(view);
        }
    }
