Most welcome 😊

[@VikramsinhChampavat]

@@PhilippLackner Hi sir, I just cloned the project from Git repo from the link given in description. Don't know why but it's not scanning any QR code even if I haven't changed a single line of whole the project Got solution after so much trials: Removing setTargetResolution line worked for me!!

Hi Phillip, ImageAnalysys.Builder().setTargetResolution has been deprecated. Can you please explain how to use ResolutionSelector with ResolutionStrategy

[@bboydarknesz]

so confuse actually, rarely playing with this stuff. but thank you for documented this!

[@marcopierucci9333]

This is great, but could you share a tip or where to look for rotation PlanarYUVLuminanceSource or BinaryBitmap? So it can work on portrait as well

[@SobhanEsmaeili]

i have the same problem did you find anything? if you find anything, please let me know

[@josephofem5448]

Hello Philip. Thanks for the amazing work you are doing on this space. This video could not have come at a better time. However, I am kinda stuck on how to run and stop the scanner on button events and also run the scanner for a given period of time before throwing a not found error. Once again, thanks a great deal

Great video here,. I actualy Search how to build qr code scanner a long ago,. And endup with mlkit + camera x,. With kotlin xml,. Now the problem is here,. Which is better using zink lib or MLKit? And can you make video how to build qr code scanner using MLkit with compose? Anway,. Big thanks for your video this time, 😁

[@lutfiikbalmajid]

BoofCV the best one, try it

[@lutfiikbalmajid]

I am try both, for performance usage boofCV are best between ZXing and MLkit

[@brgame8]

@@lutfiikbalmajid thanks for the infomation,. is boofcv support compose right now?

[@lutfiikbalmajid]

@@brgame8 i am now learninh using Jetpack Compose, and probably will trying to work with BoofCV using composr. Perhaps its work. My concern, for smartphone under 2019, so laggy, because both MLkit & boofcv is working threads, depending on RAM & CPU

Hi Philip! We don't need a list of supported image formats and the if block because the image always has the YUV_420_888 format ("The image provided has format YUV_420_888." - from documentation)

Why did you not use ML kit sdk it also offers scan barcode/qr code

[@PhilippLackner]

why would you use something that costs if you can get the same for free?

[@karthikramachandran5602]

ML kit sdk is free.Firebase mlkit is no longer there which used to cost.

Gotta limit the camera resolution by adding this to the AndroidView in the MainActivity: .setTargetResolution( Size( 640, // previewView.width, 480, // previewView.height ) )

I wanted to navigate to another screen through navigation controller. it goes to that screen but the functionality doesn't work as expected on that screen. and the design is also not properly shown. Can you make a tutorial about navigating to another screen after successfully scanning the qr code?
