hi, Is there android api 22 version of the prebuild opencv ? best
Hello, Understand opencv_videoio is not included, and saw the suggestions for android/ios. Can you please also suggest how I should capture video on linux? Thanks
From the instructions, there's how to use `opencv-mobile` in an Android APP. How can I use it in AOSP, or more specifically, android framework.
【文档】自己编译 ARM 版 opencv-mobile 解决编译器版本导致的 `undefined reference to std::__cxx11::basic_stringstream` 问题
# 起因 因项目需要在 arm 中进行简单的图形运算，于是打算直接用 [opencv-mobile](https://github.com/nihui/opencv-mobile) 仓库预编译好的 [opencv-mobile-4.5.4-armlinux.zip](https://github.com/nihui/opencv-mobile/releases/download/v14/opencv-mobile-4.5.4-armlinux.zip)。但果然因为生产环境依赖的编译器版本太旧，在编译过程遇到了因为 ABI 接口导致的错误： ```c++ undefined reference to `std::__cxx11::basic_string const&) undefined reference to `std::__cxx11::basic_stringstream const&) ... ``` 尝试直接使用 -D _GLIBCXX_USE_CXX11_ABI=0，无效 搜索一圈无果，(#20 #25 #27) 于是决定自己编译一遍，解决问题，顺便编写这个文档，方便后人查阅。...
It's a very useful repo!!! I have a suggestion that owners can release a guide on how to build opencv-mobile library on target platform with this repo and opencv official...
I found that the ios version opencv read .png as rgb (but jpeg as bgr). `cv::Mat img = cv::imread("test.png");` `cv::cvtColor(img, img, cv::COLOR_RGB2BGR);` `cv::imwrite("new.png", img);` the code above generate correct new.png,...
Mat frame; ... std::vector buf(1); cv::imencode(".bmp", frame, buf); I use full feature opencv in ios work normally but when I use opencv minimize 4.54 work abnormally.
