In case that is still relevant: I also had an issue with the datamatrix detector, wich led me to reimplement it based on the c++ port from @huycn (https://github.com/nu-book/zxing-cpp). It...

@TimZaman If you see any chance of resurrecting the datamatrix image content that caused this issue, I'd be very interested in getting my hands on that for testing. I recently...

Sorry for spamming old bug reports but in case this is still relevant: I recently started to work on @huycn s [new c++ port](https://github.com/nu-book/zxing-cpp) and that decodes this example just...

If that is still relevant to you, I'd like to point you to 'the other' c++ port: https://github.com/zxing-cpp/zxing-cpp. I completely reimplemented the DataMatrix detection code there. It works for arbitrary...

Sorry for not responding to your last comment earlier. I just wanted to let you know that I upgraded the `ZXingQtReader.h` wrapper in our example directory to support Qt6 including...

In case you don't get a satisfying response here, you might want to try an alternative zxing c++ port: https://github.com/nu-book/zxing-cpp You can easily work with NV12 data directly: `ZXing::ReadBarcodes({data, width,...

Interesting. I did a little research and according to Wikipedia and the linked [PDF](https://developer.apple.com/standards/qtff-2001.pdf) (pages 95ff) there are MJPEG-A and MJPEG-B variants. Looking at the file with a hex-editor and...

Here is the minimally invasive patch that I could come up with which adds support for reading MJPEG frames (lacking any DHT marker). Minimally invasive means smallest patch size and...

@siiky Was the above patch of help for your issue?

I just noticed that you are still using the same upstream zxing-cpp version you did about 2 years ago (something around 1.2). I just released 2.2 which has substantial improvements...
