imageproxy | A caching , resizing image proxy written in Go | Proxy library

I'm using the MLKit library for barcode scanning, so I can get a rectangle where is actually the barcode. But I'm getting a rectangle that is little than the barcode and it's not in the right position. So, the scale and the position of the rectangle are wrong.

Can anyone knows how to fix this problem? Is there any method that could re-scale and re-position the rectangle with the real measures?

Thank you :)

Here is my code:

The analysis works fine in every other Android phone I've tried (Huawei Mate 20 Pro, Samsung S8, Samsung J7 and Samsung S10+), but not in the Xiaomi Mi a20 Lite. It only enters once the the analyze function and then in the Logcat throws:

I am trying to make a barcode scanner using ML Kit and CameraX. My program would pick up the wrong scan once in a while and I have download several apps using ML Kit from google play and they have the same issue, I tested on other phones too. On the other hand, the ML Kit quick start app I pulled from Github works correctly so it has to be my code. Can anyone help me to find the issue ? I cannot upload img yet you can use online barcode generator (code 128) and create barcode for PAN/230954 my app will read as PAN/2 30954☒. Here is the barcode

MainActivity.java

I'm working on an QR scanning application that is based on CameraX. The scanning works as expected on most devices except a few random devices. After debugging this issue for a long time, I found out that the cropped image is kind of shattered on the device in which scanning wasn't working.

Expected output (works on Pixel Device):

Current output (on the devices in which scanning is not working):

The analyze method that receives each frame (part of the CustomImageAnalyzer class)

Trying to migrate barcode scanner to Jetpack compose and updating camera and ML Kit dependencies to latest version.

The current shows the camera view correctly, but it is not scanning the barcodes.
The ImageAnalysis analyzer runs only once.

Code

I am trying to use this new feature of CameraX Image Analysis (version 1.1.0-alpha08): using setOutputImageFormat(ImageAnalysis.OUTPUT_IMAGE_FORMAT_RGBA_8888), images sent to the analyzer will have RGBA format.

See this for reference: https://developer.android.com/reference/androidx/camera/core/ImageAnalysis#OUTPUT_IMAGE_FORMAT_RGBA_8888

I need to turn the image sent to the analyzer into a Bitmap so that I can input it to a TensorFlow classifier. Without this new feature I would receive the image in the standard YUV_420_888 format then I would have to use one of the several solutions that can be googled in order to turn YUV_420_888 to RGBA then to Bitmap. Like this: https://blog.minhazav.dev/how-to-convert-yuv-420-sp-android.media.Image-to-Bitmap-or-jpeg/. I assume getting the Media Image directly in RGBA format should help me avoid implementing those painfull solutions (that I have actually tried and do not seem to work very well for me so far).

Problem is I don't know how to turn this RGBA Media Image into a Bitmap. I have noticed that calling mediaImage.getFormat() returns 1 which is not an ImageFormat value but a PixelFormat one, the one logically corresponding to RGBA_8888 format, which is in line with the documentation: "All ImageProxy sent to ImageAnalysis.Analyzer.analyze(ImageProxy) will have format PixelFormat.RGBA_8888".

I have tried this:

i want to analyse all text that is just inside by box that i have in a preview camera. But im getting wrong coordinates for text.

Validation is done on contains

On one of my AWS server I have manually started a detached Docker container running willnorris/imageproxy. With no warning, it seems to go down after a few days, for no apparent (external) reason. I checked the container logs and the syslog and found nothing.

How can I find out what goes wrong (this happens every time)?

This is how I start it:

I am trying to use CameraX with ZXing library to identify barcodes, I am using ImageAnalyzer to get ImageProxy and feed its byte array to the PlanarYUVLuminanceSource to handle it by ZXing. My target rotation is 0 and the imageProxy that is coming from the camera is 90 degrees, so the barcode is not readable until I rotate it 90 degrees. here is the code:
