在上一篇博客中谈到读取中文路径的问题，本以为只要解决了这个问题后，便可以成功的运行程序。但令人没想到的是，最后使用cv2.imwrite()，将读取到的图片写入到文件夹中时，不报错，但却没有输出。
话不多说，以下是本人发现的2篇好文章，对我帮助很大

doc: update image codec configuration reference (add AVIF, fix JPEG XL) #28393
This PR updates the build configuration documentation to:
- Add AVIF to the supported format list (it was missing).
- Clarify that some codecs (AVIF, JPEG XL) do not support BUILD_* options because OpenCV does not bundle their source code.
- Update the description to include "write" capabilities for these formats.
