Drawing on top of a camera view

Hi there. I'm making an AR app and I couldn't figure out a way to draw on top of a camera view. I've created a custom SurfaceView class which uses Camera.startPreview and Camera.setPreviewDisplay to draw the real time feed from the camera upon it. Now I'm trying to render something on it. I have another SurfaceView which has a painter thread which is running with 30 fps and is drawing every frame on a Canvas obtained by SurfaceHolder.lockCanvas(). I put the two views in a FrameLayout like this
Code:
Preview cv = new Preview(
this.getApplicationContext());
Pano mGameView = new Pano(this.getApplicationContext());
FrameLayout rl = new FrameLayout(
this.getApplicationContext());
setContentView(rl);
rl.addView(cv);
rl.addView(mGameView);
And sadly it doesn't work. It shows only the camera feed. If I switch the order like this
Code:
rl.addView(mGameView);
rl.addView(cv);
The camera feed dissipates and only the painter is visible...
How should I make it work

Phew. Just to tell you I found a solution. You add this line
Code:
getHolder().setFormat(PixelFormat.TRANSLUCENT);
in the initialization of your overlay view

samsung galaxy s 4g front cam app help

Hello,
I'm trying to make a simple app where it uses the front cam to take a pic. The problem is that I just want see the preview or view finder (what ever you call it), also to make it smaller.
can any one help?
here what i got so far
Code:
Camera camera = Camera.open();
Camera.Parameters parameters = camera.getParameters();
parameters.set("camera-id", 2);
camera.setParameters(parameters);

any help? it do not have to be with SGS4G it can be for any phone!

Decompiled Camera APK

hi Guys
Ive decompiled the Camera APK from the HONE and found something interesting as below;
Code:
# static fields
.field private static final synthetic $VALUES:[Lcom/android/camera/HTCCameraSensor$Sensor_Type;
.field public static final enum SENSOR_13M:Lcom/android/camera/HTCCameraSensor$Sensor_Type;
.field public static final enum SENSOR_2M:Lcom/android/camera/HTCCameraSensor$Sensor_Type;
.field public static final enum SENSOR_3M:Lcom/android/camera/HTCCameraSensor$Sensor_Type;
.field public static final enum SENSOR_4M:Lcom/android/camera/HTCCameraSensor$Sensor_Type;
.field public static final enum SENSOR_5M:Lcom/android/camera/HTCCameraSensor$Sensor_Type;
.field public static final enum SENSOR_8M:Lcom/android/camera/HTCCameraSensor$Sensor_Type;
.field public static final enum SENSOR_UNDEFINED:Lcom/android/camera/HTCCameraSensor$Sensor_Type;
Notice the different sensor types?
Plus i think ive found that the HTC One maybe able to take higher than 4 MP photos... Dependant on the sensor of course ^__^
Attached are 3 files;
Notepad ++
APKTool Decompiler
HTC One Camera APK.

So u mean that the camera sensor is capable of taking higher res pix ?
Can u share how to decompile the camera apk
Thnx

Perhaps they have a standard cross-platform HTC camera app and it just limits itself dependant on what hardware it finds.

There is that possibility , it depends though as mentioned above by Tetsumi06, if the software does not permit them because the sensor is truly a 4MP sensor... But knowing HTC and their history with cameras, i wouldn't be surprised if it was possible. back on earlier models, HTC never enabled 1080p & 720p recording and the community came together to get them enabled.
Im hunting now.... Tools i used to decompress are attached to the first post

EDIT:
Tetsumi06 said basically the same thing! Doh!
It could also be that the code is generic to all device types and models and so has a function to pickup the sensor size based on the hardware it sees. So there might be functions for other sensor sizes but they never get enabled because physically our phones are only 4M.
I would love to be wrong though! Good find!:laugh:

HTC is working with one !!! source base. So there are often parts inside a app which are handled differently regarding some build settings.
And same here for the camera sensor strings. The same camera.apk (build number will differ) will run on other devices like Butterfly, One X, One XL, ...
So there must be some checking in the source how to handle different sensors :laugh:

See what you say is very true, one source of android 4.2.2 for example, for all 2013 devices but they add and remove what is necessary to make those devices work... They develop one load of sense based firmware to then place with drivers for the individual devices ):

You can edit the media_profiles.xml to change the image compression, and video recording bitrate. Need to make the same changes in the camera apk and compile it again

cool worth keeping an eye on

HTC Uses a single base for all its phones so they all have the same encodings. This Apk would work on a phone with 8mpx camera and vice versa. You Cant Have More Pixelsssss.

I think our sensor has more abilities and functions but we need someone to hunt and edit it
Have a look here it's kinda long but interesting

They might make all their apps compatible with various hardware to allow easier updating of each device's Android version.

I kinda doubt what u sayin cuz look at picture size values u will notice that it's limited to max 4mp which is for HTC one
Anyways am not looking to increase the megapixels there's much more options like jpeg quality is 85% ! I can see higher video frames ! More scenes !
Maybe we can increase the quality if slow motion video ! Or make it even slower than 4x
Am I right !

The one thing that caught my eye was the different metering options. Being able to choose different types of metering would be awesome, along with changing the jpeg compression

Use virtuous studio.
Anyway from the code we can pretty much change anything the only issue is we don't know the sensor capabilities, what is max that it can do.
For example max exposure is 12 if I remember right from the code, so if the sensor is capable of doing 16 and we set it to 14 we would get better low light photos.
We could change metering distance but again we need to know sensor capabilities for example if minimum is 5 cm we could add 3 cm which would allows us closer macro shots.
We could boost the flash as well, Make the duration longer = more time for sensor to pick up the light = better pic.
Or we could increase zoom distance as well since we can assume HTC gave us short zoom since our pixel count sux , tho I'm sure 20/30% won't ruin that much the quality ( anyway not like anyone is ever using zoom lol)
Best of all would be adding touch focus flash @ night since we lack that option. Then set it to lock focus for let's say 4 sec and take a pic.
We could even add 60 fps1080p recording tho that would make 1 min clip 300 mb + lol.
We have sh1t load opportunities here all we need is either to test on blind some stuff or somehow get the hardware specs of our sensor

[Q] Activate continuous auto-focus on Samsung sm-c105

Hi everyone,
I am currently developing a camera application for the Samsung galaxy s4 zoom (sm-c105). I would like to activate the continuous auto-focus.
Here is what I do. It's working on my galaxy s5:
Code:
mCamera = Camera.open(defaultCameraId);
Camera.Parameters params = mCamera.getParameters();
if (params.getSupportedFocusModes().contains(
Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE )) {
params.setFocusMode(Camera.Parameters.FOCUS_MODE_CONTINUOUS_PICTURE);
}
I have tried all the other focus mode, but nothing is working. Even when i request focus with a callback, nothing is happening.
The galaxy s4 zoom use a special camera lens. I think this the source of my issue. I searched for a special camera api from Samsung but I didn't found nothing.
Would you have any leads?
Thanks.

Adb command to use the tele lens from 4x in the official Samsung camera app

Hi, we know the camera app won't use the 4x tele zoom until we zoom at 10x, even when lighting conditions are good enough and the zoom camera would give much better results (we know that from comparison with GCam).
While looking at the output of adb shell dumpsys media.camera, I noticed a suspicious samsung.android.scaler.zoomMapRatio variable with a value of 10.
With the command adb shell am start -a android.media.action.IMAGE_CAPTURE --ei samsung.android.scaler.zoomMapRatio 0 I can start the camera app and force this variable to zero... And suddenly the app switches between the main and the zoom cameras between 4x and 5x (depending on your lighting conditions) !
Now I need to find a way to start the camera on the phone with this command line - the setting is lost when closing the app.
Video demonstation - I run the adb command at 5s:

My bad, thx for the cleanup

I'm not sure what's the best way to launch the camera while forcing this setting...
I can write a launcher app, but the following code does work except we only get to take a photo - we cannot change mode (photo/video/portrait/etc.)
Code:
val takePictureIntent = Intent1(MediaStore.ACTION_IMAGE_CAPTURE)
takePictureIntent.putExtra("samsung.android.scaler.zoomMapRatio", 0) // <== Magic !
try {
startActivityForResult(takePictureIntent, pic_id);
} catch (e: Exception) {
// display error state to the user
}
The result in video:
