Camera2 API

Brill thanks again! I'm learning loads lol.

I just added the extra line you suggested and it works like a charm! Open Camera 1.47.3 (the latest from Play) reports 14 cameras in Settings/About and you can switch between them using the camera switch icon.

The 1st 5 work OK and 6 reports a serious camera error. If you keep tapping, you get a blank screen each time, and eventually it works again, but it starts at camera 1 (selfie) so it looks like Open Camera gets upset at camera 6. To get camera 0 again, you have to close Open Camera and kill the task, restart it again and it's on Camera 0.

I have often thought I should build my own version of Open Camera, but never got round to it. Maybe it's time once I get other projects out the way.

Have a good evening.

It occurred to me that it would be nice if Open Camera had an option to display the current camera on screen so I've asked the nice Mark to consider it here:

Yes it is very easy to build your own version of opencam, and you can simply modify this for your device to show the text you want at each camera pos

at the function clickedSwitchCamera in MainActivity.java

Code:

     public void clickedSwitchCamera(View view) {
        if( MyDebug.LOG )
            Log.d(TAG, "clickedSwitchCamera");
        if( preview.isOpeningCamera() ) {
            if( MyDebug.LOG )
                Log.d(TAG, "already opening camera in background thread");
            return;
        }
        this.closePopup();
        if( this.preview.canSwitchCamera() ) {

            int cameraId = getNextCameraId();
            Log.d(TAG, "HII THERE: "+cameraId);

            if(cameraId==6)
                cameraId=7;
            if(cameraId==8)
                cameraId=9;
            if(cameraId==10)
                cameraId=11;
            if(cameraId==11)
                cameraId=12;
            if(cameraId==12)
                cameraId=13;
            if( preview.getCameraControllerManager().getNumberOfCameras() > 2 ) {
                // telling the user which camera is pointless for only two cameras, but on devices that now
                // expose many cameras it can be confusing, so show a toast to at least display the id
                String CamText="";
                switch (cameraId){
                    case 0:
                        CamText=" Wide 27Mpx";
                        break;
                    case 1:
                        CamText=" Selfi Cam";
                        break;
                    case 2:
                        CamText=" 12Mpx 2X zoom portrait";
                        break;
                    case 3:
                        CamText=" UltraWide 20Mpx";
                        break;
                    case 4:
                        CamText=" Macro 2Mpx";
                        break;
                    case 5:
                        CamText=" Zoom 5X 5Mpx";
                        break;
                }

                String toast_string = getResources().getString(
                        preview.getCameraControllerManager().isFrontFacing(cameraId) ? R.string.front_camera : R.string.back_camera ) +
                        " : " + getResources().getString(R.string.camera_id) + " " + cameraId+ " "+ CamText;
                preview.showToast(null, toast_string);
            }

            View switchCameraButton = findViewById(R.id.switch_camera);
            switchCameraButton.setEnabled(false); // prevent slowdown if user repeatedly clicks
            applicationInterface.reset();
            this.preview.setCamera(cameraId);
            switchCameraButton.setEnabled(true);
            // no need to call mainUI.setSwitchCameraContentDescription - this will be called from PreviewcameraSetup when the
            // new camera is opened
        }
    }
            }

Well you're just the gift that keeps on giving

Thanks for the code. Yes, that does look easy. I can't touch it right now as I'm motorising my microscope with a pic chip to do focus stacking and have promised myself I'll finish it before taking on another project lol. I see Open Camera is compiled in Android Studio so I'll download it and have a play, probably next week.

For interest, I've edited build.prop and added footej camera (com.footej.camera) and camera2test (com.airbeat.device.inspector). Footej does not seem to support any extra cameras, only front and back so +1 for Open Camera. Camera2test did show more cameras, but the 27MP repeated cameras are shown as 4032x2034, or 12MP so I think it's wrong. More importantly, still no 108MP

I've attached the (very long) screenshot of Camera2Test.

TF1920 · Dec 9, 2019 at 7:38 PM

The 108Mpx seems elusive for now, in the stock cam they add a new stream configuration so this mode is enabled

Code:

CameraCapabilities: addStreamConfigurationToList: xiaomi.scaler.availableSuperResolutionStreamConfigurations: size = 15

Setting that is what updates the max resolution to

updateSize: picture size is: 12032x9024

But still didnt find how to call it from code to enable it for the camera2 api

picitup · Dec 9, 2019 at 8:22 PM

Oh so it's configured at runtime? I think if anyone can find it, you can

TF1920 · Dec 11, 2019

Yes the 108Mpx mode is there if you use the adb sell and type:

Code:

adb shell dumpsys media.camera > camera.txt

you get all the info from the cam

Code:

 xiaomi.scaler.availableSuperResolutionStreamConfigurations (80420000): int32[60]
        [35 12032 9024 0 ]
        [35 12032 9024 1 ]
        [33 12032 9024 0 ]
        [35 6016 4512 0 ]
        [35 6016 4512 1 ]
        [34 6016 4512 0 ]
        [34 6016 4512 1 ]

and it even opens the possibility of raw ?
android.scaler.availableRawSizes (d0008): int32[14]
[12032 9024 6016 4512 ]
[752 4464 3008 2256 ]
[752 1116 3008 2256 ]
[752 1116 ]

picitup · Dec 12, 2019 at 12:43 PM

Wow if we could get 108MP raw that would be the best!

I'm back home now and had some time this morning so I installed Android Studio, Open Camera source and after some fiddling got it working. What threw me a bit, was when I tried to build it, nothing happened, no error messages, nothing. However once I''d created a virtual device with Tools/AVD and installed the Pie binary, it all worked fine.

So now I have a custom version of Open Camera as I've added your mods. I'll have a proper play later and report back.

Thanks once again for all your efforts.

Steve

picitup · Dec 12, 2019 at 6:53 PM

After playing with Open Camera, it seems that camera id 9 is causing problems with my EU rom. After camera 9 is used, Open Camera no longer updates the screen with the camera image.

Just for now, I've modded the code to limit the last camera id to 5 which seems to work fine:

Code:

            int cameraId = getNextCameraId();

          [B]  if(cameraId>5)  cameraId=0;[/B]

         
            if(cameraId==6)  cameraId=7;
            if(cameraId==8)  cameraId=9;
            if(cameraId==10) cameraId=11;
            if(cameraId==11) cameraId=12;
            if(cameraId==12) cameraId=13;

Morning

I was poking around the Mi9 forum and found this thread:

[APP][MOD][MAGISK] 48MP and improvements for GCam

https://forum.xda-developers.com/Mi-9/themes/app-48mp-improvements-gcam-t3992597/page2

I appreciate it's for another camera module, but wonder if there's any clues for our sensor there?

Cheers

Thanks Steve, looks interesting, since there is no code I have downlaoded and trying to decompile it to see what it does, looks dangerous by the comments in the thread

Camera 9 works for me but it is weird bottom half of the picture is green stripes and upper the image is duplicated like a stereo pic...

Also found in the file at /data/property some persist properties related to the camera:

Code:

persist.camera.rearMain.vendorID 03
persist.camera.frontMain.vendorID 01
persist.camera.rearTele4x.vendorID 03

persist.camera.module.infoext2 Iback_camera_aux=F4_sunny_OV_ov02a10;back_camera_aux=F4_sunny_Sony_imx350
persist.camera.algoup.disableldc 0

And there are plenty more camera props if at adb you check all of them

Code:

find . -name '*so' | xargs strings | grep '^persist\.'

Finally Got it hacked!!!

108Mpx with Opencamera

Will Post the instructions in the OpenCameraThread

TF1920 · Dec 20, 2019

Source code to enable it is here: https://forum.xda-developers.com/mi-note-10/themes/enable-5-cams-opencamera-108mpx-mode-t4016279

Btw it takes 108Mpx pictures faster than the stock camera app, not tested quality yet.

and it seems to work with raw too it takes about a minute to take if raw enabled but nothing is stored so may need further works

picitup · Dec 20, 2019 at 9:11 AM

Sound like you cracked it wide open! Well done

I'll try it out today and report back on the other thread.

You should add a donate button to your account.....

108 faster than stock? My stock app takes 108 immediately.
