cameraview's Issues

Video orientation settings (front & back camera)

Hello !

Thanks for this great lib, working like a charm!

I'm currently using CameraView in my app for taking several video sequences. At the end of the user flow, I'm merging all these sequences to create one video. For this purpose, we use mp4Parser, another great lib!

The problem I have now is that I have my sequences from the front camera upside down after the merge. I assume that it's an orientation issue:

• front camera sequence has an orientation of 270
• back camera sequence has an orientation of 90

The issue is described here

So the merge doesn't take into consideration this difference of orientation and set to the front camera sequences an orientation of 90 instead of 270 that's why they are upside down in the result.

Is it possible to have a mode/methods where we could have access to the metadata of the video created by CameraView or eventually to have access to the mediaRecorder? My idea would be to put the same orientation to both side sequences in order to avoid the upside down result after the merge.

Thank you in advance!

Odd even video rotation issue in video capture

I am using the library for capturing multiple videos in one (like instagram).
But the issue is that when we flip the camera from real to back the rotation goes wrong.
Example scenario: If we start video capture from rear, and capture a video then flip the camera to front and capture a video and repeat the same for all video clips, the final video will contain all rear video clips with rotation 90 (correct) and all front video clips with rotation of 270 (Up side down - incorrect)
Please make the rotation value to be changed dynamically no matter how many times we capture the video.

Question: Round darken overlay

Is something like this https://i.stack.imgur.com/NszHG.png possible?
I need this because I want that my users make profile images - and these pictures are round in my app. So it would be great if the users are seeing exactly what they will get.

Lost focus after taking picture

Hi. I have an issue with focus after taking picture. Autofocus works ok on tap, but after I press capture the picture loses its focus and gets blurry. Is there any solution for this?

camera view set zoom point

The current api allows setting zoom around center only either by pinch or scroll. Is it possible to zoom around specific point not only from center but say from where pinch started?

Setting parameters while camera is restarting (for example right after setFacing)

Hello!

I found another error. Maybe it's a library error.

An error occurs if we try to switch the HDR or white balance.

I do as you said before:

1. camera.stop();
2. Set the settings (front or back, grid, quality, etc.)
3. camera.start();

Everything works fine if we not use setHDR or setWhiteBalance. It does not matter where we apply the settings (before the camera.start() or after). Using these two settings in onResume does not cause errors.

Here are two pictures with errors:

1. For HDR:
   

2. For WhiteBalance:
   

Error while stopping the camera engine - NPE

Sometimes I get a NullPointerException when trying to stop the camera:

Retrieve video recording time

Can the recording time be retrieved and displayed in either a TextView or used to update a ProgressBar?

Stock snapshot/image byte array

Could you please add some functionality to provide return stock byte array from snapshot/image?
I think it would be much better if user will have ability decide what to do with this byte array.
It may be some kind of option.
Like captureImage(boolean processImage) and captureSnapshot(boolean processImage)

Any recommendation?

Bug: Capturing videos on Android API < 23 fails

I got another issue: at least when using the Android Emulator, taking videos failes for Lollipop and older. Unfortunately, I can't test it on a real device, but maybe anybode can confirm the bug or restrict it to the Emulator?

Trying to read the created video file, it seems as if it does not contain a single frame. The file itself was created though and has write access.

This is the full log.

Running my own app, I get the same problem, but the log looks a little bit different. The only obviously-related error I can find is 09-27 18:51:50.900 2218-2218/com.siwalusoftware.dogscanner E/MediaRecorder: stop failed: -1007.

Risk of Repository Takedown

I don't know if forks of this repo got the same notification, but I wanted to inform you that this library has been reported for copyright infringement by the original library I had forked, lots of lines and commits ago: the successful CameraKit-Android.

I am sure you know this, because a link to that repo has always been pretty evident in our README. In a few words, guys at CameraKit-Android are complaining about me not reporting info of their license. Sadly, that's true - a long time ago I had relicensed the repo to Apache in order to be consistent with other libraries of mine, without thinking that I should have kept the original MIT too.

That was made out of distraction and was not a smart move, but hey, we learn from errors. I am deeply sorry that the original authors felt this as an offense to their work, and have fixed it with #68 (relicensed this repo to MIT as well, for simplicity).

GitHub policies give us about approximately 24 hours (sic) to fix the infringement, and the copyright owner has to agree that the issue is fixed. If they don't, GitHub will shutdown this repo immediately without checks. Bintray will probably follow, so the library won't be available anymore in gradle. I have done what I could, and now it's up to guys there.

The report I got seemed very angry and targeted the whole repository. Again, this is just, and we were wrong. But that's sad too - if they had just filed an issue here, I would have acknowledged my error and added back their license. It looks clear to me that we never wanted or aimed at hiding our parent repo - it has always been the first link in our README file. We were in good faith.

Today we got to 400 stars, which makes me happy, but we are far from being as successful as them, and there's a lot of work to do. We clearly have taken different directions - the two repos share about 5% of meaningful lines, and that number can only decrease over time. I would like to keep this going, but if the guys there decide to proceed, there is not much I can do.

I have tried to get in touch with them but currently had no response. I hope I will have one so we can figure out what's wrong together. But if you come and find this closed, well, I'm sorry.

startAutoFocus - getParameters or setParameters failed

The startAutoFocus causes a crash, because either getParameters or setParameters failed.

Fatal Exception: java.lang.RuntimeException: getParameters failed (empty parameters) at android.hardware.Camera.native_getParameters(Camera.java) at android.hardware.Camera.getParameters(Camera.java:1632) at com.otaliastudios.cameraview.Camera1.startAutoFocus(Camera1.java:767) at com.otaliastudios.cameraview.CameraView.onGesture(CameraView.java:459) at com.otaliastudios.cameraview.CameraView.onTouchEvent(CameraView.java:438)

and

Comes from different devices actually supporting auto focus.

Any thoughts?

Feature Request: Frame Processor

I love this library! It's the best camera library I've tested. Thank you so much for working on this.

The one thing missing is a frame processor so I can do barcode detection and facial recognition. Fotoapparat supports Frame Processing, so I use that, but CameraView supports way more features, like tap-to-focus, so I'd love to switch over.

Thank you

Image lagging on 4.4.2 lg device

after image taken it is lagging , not giving smooth scrolling of bottom layout.

Specify image resolution

Hello! This is one of the best libraries for working with the camera now. But is it possible to specify a resolution for shooting? Now, as far as I understand, the library takes a picture in the maximum possible resolution and cuts it under the resolution of the sides of the device. Is it possible to make the application initially take a picture, for example, with a resolution of 1920 * 1080?

Auto Exposure Lock

Hello, Mattia

Can you provide auto exposure lock please ?

Thank you !

Dual Camera

Hi!

Can I use your library to work with two cameras at the same time?

As a basis I used your example, but I made two CameraView elements: masterCamera and slaveCamera.

Additionally, I changed the code for the button that switches the cameras.

`
int NextMode = 0;

@OnClick(R.id.toggleCamera)
void toggleCamera() {
    if (mCapturingPicture) return;

    masterCamera.stop();
    slaveCamera.stop();

    switch (NextMode) {
        case 0:
            masterCamera.start();
            masterCamera.setFacing(Facing.BACK);
            slaveCamera.setVisibility(View.GONE);
            NextMode = 1;
            break;
        case 1:
            masterCamera.start();
            masterCamera.setFacing(Facing.FRONT);
            slaveCamera.setVisibility(View.GONE);
            NextMode = 2;
            break;
        case 2:
            masterCamera.start();
            masterCamera.setFacing(Facing.BACK);

            slaveCamera.start();
            slaveCamera.setFacing(Facing.FRONT);
            slaveCamera.setVisibility(View.VISIBLE);

            NextMode = 3;
            break;
        case 3:
            masterCamera.start();
            masterCamera.setFacing(Facing.FRONT);

            slaveCamera.start();
            slaveCamera.setFacing(Facing.BACK);
            slaveCamera.setVisibility(View.VISIBLE);
            NextMode = 0;
            break;
    }
}`

As a result, the application does not always work correctly. After several camera mode switching, an error occurs and the application is closed.

I run tests on the Nexus 10 emulator (API 23, Android 6).

How to work with two cameras at once? Or is the error due to the emulator?

Recorded videos are not cropped

I used your application to implement capturing images, I use the crop output in XML to crop the image. This works fine, here is the code.

<com.otaliastudios.cameraview.CameraView
android:id="@+id/camera"
app:cameraJpegQuality="75"
app:cameraSessionType="video"
app:cameraWhiteBalance="auto"
android:keepScreenOn="true"
app:cameraCropOutput="true"
android:layout_width="wrap_content"
android:soundEffectsEnabled="false"
android:layout_height="@dimen/camera_crop_amount" />

I am now implementing capturing video, using the same XML properties. However, my video is not being cropped to the same size as the preview. Is there any reason why this happens? I am more than happy to provide additional information if required. Please let me know.

Just checked your demo app that doesn't seem to crop video output either.

P.S I am using the Samsung Galaxy S7

Thanks

Error while starting/stopping the camera engine - Camera is being used after Camera.release() was called

As requested in #26, I'm opening a new issue:

Your latest changes seem to have solved the very most of the Camera is being used after Camera.release() was called issues. However, I'm afraid it's still not solved 100%. I got one more error:

Code lines are refering to the master branch of my fork using the extended error handling, but that shouldn't be a problem.

It's very seldom though and seems to be the case when the camera is stopped before it finished starting.

NullPointerException in startVideo

I'm getting quite a lot NullPointers when users are trying to record a video:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.hardware.Camera.lock()' on a null object reference at com.otaliastudios.cameraview.Camera1.startVideo(Camera1.java:611) at com.otaliastudios.cameraview.CameraView.startCapturingVideo(CameraView.java:1153) at com.otaliastudios.cameraview.CameraView.startCapturingVideo(CameraView.java:1180)

So mCamera seems to be null here. The onCameraOpened event has already been triggered before. Unfortunately, I do not have any extended error logs as I only received the crash reports in Crashlytics. However, it seems to be device and os independent.

Disable the sound in dispatchFocusEnd

Is it possible?

Video timer inconsistencies

I know you have already closed an issue similar to this, but I think you would understand best how to approach such an issue as you know how all of your code works. As the title says after hitting record I show a time elapsed.

I have used CountDownTimer:

`new CountDownTimer(10000, 1000) {

                    public void onTick(long millisUntilFinished) {
                        forcePressNext = true;
                        timerVideo.setText(20-millisUntilFinished/1000 + "s");
                    }

                    public void onFinish() {
                        timerVideo.setText("10s!");
                        if (forcePressNext == true) {
                            isRecording = false;
                            cameraView.stopCapturingVideo();
                        }
                    }
                }.start();`

It is quite inconsistent by 2/3s and the inconsistency gets larger on older devices, have you got any ideas?

thanks

After passing to the version 3.0 of Android Studio and to the version 27 of buildTools and support library, I had this crash immediately when I open the activity the CameraView is into. Maybe you have an idea about that?

Flipped Images or Mirrored Images

When taking an Image using the front camera, image appears to be flipped / mirrored. As of now I have handled this in my code using:

Matrix m = new Matrix();
m.preScale(-1, 1);

But this involves more processing as bytes[] are converted to bitmap and again bytes[] to perform file storage and displaying purpose.

Stretching out image

Hey,

We are having an issue with Camera view stretching and not showing in full screen for Galaxy tab 4 android version 5.0.2.

On other devices tested so far the view works fine.

See the screenshot

Small error: cameraJpegQuality 0 <= n <= 100

Apparently there is a small error in the documentation: the quality of the jpeg must be greater than 0 and less than or equal to 100 (0 < n <= 100).

If you try to set 0, then there will be an error:

java.lang.RuntimeException: Unable to resume activity {com.myapp.myapp/com.myapp.myapp.MainActivity}: java.lang.IllegalArgumentException: JPEG quality should be > 0 and <= 0

Switching SessionType while in another orientation stretches the preview

Hey,

My requirement is to have 4:3 aspect ratio for picture and fullscreen for video. In portrait this works fine when switching between PICTURE and VIDEO but if I rotate the device to landscape and switch the preview is stretched.

https://www.dropbox.com/s/z573aa0285lhaov/orientation_change_stretch.mp4?dl=0

Perhaps is there a way to disable the orientation and keep them in portrait or landscape, or manually set an orientation for this not to be stretched?

Thanks
