redapparat / fotoapparat Goto Github PK

The wiki page is a bit badly structured making the Rx example very incomplete.
I would suggest adding a page with a better example of its usage, the needed/possible import versions like compile 'io.fotoapparat.fotoapparat:adapter-rxjava2:1.0.2' and maybe start adding Kotlin examples.

Hi
One of our users is getting these crashes whilst trying to use the camera.

Hey guys, is it possible to trigger a callback when saveToFile has finished execution? I've been trying to create a new PendingResult.Callback but can't seem to figure out the proper Callback type.

   PhotoResult photoResult = fotoapparat.takePicture();

    File f = new File(
            getActivity().getExternalFilesDir("photos"),
            "newImage.jpg"
    );

    PendingResult.Callback<?> callback = new PendingResult.Callback<Void>() {
        @Override
        public void onResult(Void v) {
            Log.d(TAG,"SAVE FILE CALLBACK");
        }
    };

    photoResult.saveToFile(f).whenAvailable(callback);

Hey, is there any way to toggle the flash mode without using FotoapparatSwitcher?

Hi, I want to know how to save photo captured as byte array directly.
In this sample code :
`private void takePicture() {
PhotoResult photoResult = fotoapparatSwitcher.getCurrentFotoapparat().takePicture();

    photoResult.saveToFile(new File(
            getExternalFilesDir("photos"),
            "photo.jpg"
    ));

    photoResult
            .toBitmap(scaled(0.25f))
            .whenAvailable(new PendingResult.Callback<BitmapPhoto>() {
                @Override
                public void onResult(BitmapPhoto result) {
                    ImageView imageView = (ImageView) findViewById(R.id.result);

                    imageView.setImageBitmap(result.bitmap);
                    imageView.setRotation(-result.rotationDegrees);
                }
            });
}

`

I can read from photo.jpg and then save to byte array variable . But how to directly read the photo data as byte array? Thank you

What to fill for x.y.z?

can you check it ,please.When i rotate screen portait to landscape, camera in landscape mode is zoomed,when i rotate back it normal.

If I put a CameraView in a RecyclerView, and then scroll away from it for more than a few seconds, when I scroll back it is gone (or at least the preview is no longer showing).

In some devices i faced an issue that its not capturing the Photo by the front camera.

Ex: One Plus 2 etc...

Sorry for no logs as its not showing any.

This error was solved when i remove the flash section

fotoapparat = Fotoapparat
.with(this)
.into(cameraView)
.photoSize(standardRatio(biggestSize()))
.previewSize(standardRatio(biggestSize()))
.lensPosition(front())
.focusMode(firstAvailable(

.logger(loggers(

.build();

So what will happen if some devices have front facing flash....

and can you please provide a method to flip the front face selfie?

I am getting this crash via crashlytics

Not sure why, but taking pictures with Camera2 is couple of seconds slower then Camera1. I suspect that it might be related to re-focusing the camera.

Device : OnePlus 2
API level : 23
Image links : before capture https://drive.google.com/file/d/0B7Rq1Vju8a84c0FMbVpNRTg3d28/view?usp=drivesdk

After capture
https://drive.google.com/file/d/0B7Rq1Vju8a84SXNZdm9xVlFkbmM/view?usp=drivesdk

When Parameters have either a null FOCUS_MODE or FLASH parameter in camera2, when taking a photo FA will crash with a not explicit stacktrace.

I.e. the 'whenAvailable(..)' callback is never invoked for some reason.
Same story when I do the same thing with the synchronous .await()
I'm using the same code as you have on your main github page.

Tested with:
Samsung S6 Edge (Android 6.0.1): Failed
Samsung S8 (Android 7.0): Failed
Samsung S5 (6.0.1): Failed
LG Nexus 5X (7.1.2): Success

Will test Google Pixel C Tablet tomorrow.

I never waited more than 15 minutes for the callback to be invoked.

I was replacing my old camera-handling code with Fotoapparat while updating an existing project, the old code still works fine so I doubt it's a hardware issue.

I get a lot of crashlogs on devices with Android 4.2 and 4.4 (most are Samsung):

                    .build();

Hi, thank you very much for your time. is there any way to get the autofocus callback? seems like FocusResult is not available from getCurrentFotoapparat().autoFocus();

Thank you again.

I try to convert frame.image(Byte Array) to Bitmap with this code
BitmapFactory.decodeByteArray(frame.image, 0, frame.image.length);

But, bitmap always return null. How can I convert frame.image to bitmap?

Logcat message: --- SkImageDecoder::Factory returned null

Preview of Camera2 is significantly slower than preview of Camera1 while using the same device (in particular on Moto G3).

I already did some research and asked the question (with a bounty on it) on StackOverflow: http://stackoverflow.com/q/43687624/926907

If we won't get our answer until bounty expires we'll have to drop support of frame processors in Camera2.

I am curious to know if there is a simple solution that I am overlooking (there probably is, I am not yet great with layouts). I am wanting my cameraView to show the full uncropped sensor. I was thinking that the following would work in my layout:

<!--NOTE THIS IS FOR PORTRAIT VIEW-->
<io.fotoapparat.view.CameraView
android:id="@+id/camera_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"/>

But it is still cropping to fill the screen. I worked out a solution by programmatically setting the width to the screen width, getting the biggest size photo parameter, figuring out the aspect ratio from that parameter and then setting the view height based on the calculated aspect ratio. I feel like this should work for most purposes but there may be edge cases where this breaks. What is the best practice for showing the full uncropped camera preview? Thank you for this amazing library, it has been extremely helpful to me and has been great to work with.

First of all thanks for your great library, I've ran sample code into android emulator API version 25, but onResult not called in photoResult for saved image, I've test your code in Sony API 23 and it's work fine.

Can you help me to fix this issue.

This is a good and reliable library, but it is not complete. Taking picture AND recording video are bound together. One without another is a 3 wheeled Lamborghini.

Hi,

I'd like to configure the camera's ISO (sensor sensitivity), aperture, and exposure time settings. It looks like these may be possible in the old API with Camera.Parameters and in camera2 with CaptureRequest, with varying hardware support. This library doesn't seem to provide a way to access or inject them. Is it possible to provide this ability?

i didnt find x.y.x values for compile 'io.fotoapparat.fotoapparat:library:x.y.z'
please help.

I dont know if you have seen this one before or if it is fixed in 1.0.1

Hey guys, thanks for this very useful library.

Problem:
When using a Moto G4, I can take a picture once. But the second time I try to take a picture, it doesn't work.

Details:

• When it fails, I see autoFocus in the Fotoapparat logs, but takePicture never shows up.
• The OS version was api 25
• I tried this on 4 phones:
  • Samsung S5: no issue
  • Samsung S6: no issue
  • Moto G: no issue
  • Moto G4: fails
• Snippet where I initialize fotoapparat:

fotoapparat = Fotoapparat
                .with(this)
                .into(cameraView)
                .lensPosition(back())
                .logger(loggers(logcat()))
                .focusMode(firstAvailable(  
                       continuousFocus(),
                       autoFocus(),        
                       fixed()             
                ))
                .photoSize(wideRatio(biggestSize()))
                .build();

• If I change the snippet to:

fotoapparat = Fotoapparat
                .with(this)
                .into(cameraView)
                .lensPosition(back())
                .logger(loggers(logcat()))
                .focusMode(autoFocus()) //  <---  this line changed
                .photoSize(wideRatio(biggestSize()))
                .build();

this issue doesn't arise. But then obviously I can't use continuous focus mode.

Unfortunately, I don't have access to the problematic device right now, so I can't do additional testing. If this issue isn't solved because of that, feel free to close it, and I can open an issue again when I get access to the device.

Since d8fad94, my app now crashes with this backtrace:

When camera2 was the default, the app did not have this problem.

Device: Nexus 6P

Potentially due to sensor orientation degrees as camera 2 with other devices ( #12 ).

Hey guys, thanks for this awesome library. I just wanted to check out with you, whether you plan to implement video capabilities. Is it planed or already implemented/possible to implement?

Sadly there are still many unresolved issues in Camera2. To not delay the release we'll turn off Camera2 implementation and will bring it back in future versions. API and design for supporting different Camera implementations remain untouched.

Front facing camera photo orientation is not correct

From #21 focusing only on camera aperture

Fatal Exception: java.lang.IllegalArgumentException: Opened camera does not support the selected focus_mode options.

I am getting this on 1.0.0, if it now fixed then I am sorry to bother you

From #21 focusing only on ISO configuration

After

photoResult.saveToFile(someFile)

how can I retrieve the URI of the saved image?

After taking pictures will be stuck for a while, this problem can be improved?But the system camera after taking pictures, will not be stuck for a while
Please help me out this problem。thankyou

Is there anyway I can use this library in a way where I am forcing it to only use the front facing camera?

If you'd like to use other resolution than the provided biggestSize() and smallestSize() you can't or at least it's not documented. I'd like to do some JNI image processing and for that I need to find a sweet spot between the max and min resolutin.

could you add a getter for

private boolean started;

so the when I call

@OverRide
public void onPause() {
super.onPause();
fotoapparat.stop();
....
}

I can do

@OverRide
public void onPause() {
super.onPause();
if(fotoappart.isStarted()) fotoapparat.stop();
}

When there is no flash support in mobile it crashes.

java.lang.NullPointerException

How to find out the version of the library

Device: Moto G3

The resulting picture is roughly 4000x3000 pixels. That is way too big for this device to be displayed in ImageView. We should consider adding an option for downscaling the image.

Devices: S7 Edge, Moto G3

While using rear camera photo is not rotated correctly. Camera1 works as expected.

Device: S7 Edge

This screen is actually 30" and certainly not square :)
