In ARM platform, camera pix format NV12, how can I detect the QR from NV12 stream?

[Jimmy-Nie]

1. I use the ARM Platform: ARMv7
2. I have finished complie the zxing lib
3. Camera output NV12 format pix
4. How can I detect QR from the stream?

I try transfer NV12 to png using OpenCV, but it's slow, does this zxing support detect QR from yuv stream?

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, height, ImageFormat::Lum, stride}).
