遇到的问题
我的配置： Vitis Vision 2022 + opencv-4.4.0 + vision Library 2022
Vitis HLS 2021.1 实测有BUG，编译好之后无法综合，别问我为什么知道
1. Download opencv_ffmpeg.dll 卡住
解决方法
打开
new_build
目录（编译路径），找到 CMakeDownloadLog.txt
#use_cache "D:/Vitis_HLS/opencv/sources/.cache"
#do_copy "opencv_ffmpeg.dll" "6899624f88cb4cbb1604edc5e12b18ab" "https://raw.githubusercontent.com/opencv/opencv_3rdparty/bf1730f4c4ba1996bed1fe268b52e4e942151cd6/ffmpeg/opencv_ffmpeg.dll" "D:/Vitis_HLS/opencv/new_build/3rdparty/ffmpeg"
#missing "D:/Vitis_HLS/opencv/new_build/3rdparty/ffmpeg/opencv_ffmpeg.dll"
#cmake_download "D:/Vitis_HLS/opencv/sources/.cache/ffmpeg/6899624f88cb4cbb1604edc5e12b18ab-opencv_ffmpeg.dll" "https://raw.githubusercontent.com/opencv/opencv_3rdparty/bf1730f4c4ba1996bed1fe268b52e4e942151cd6/ffmpeg/opencv_ffmpeg.dll"
#try 1
找到并复制其中的下载链接 https://raw.githubusercontent.com/opencv/opencv_3rdparty/bf1730f4c4ba1996bed1fe268b52e4e942151cd6/ffmpeg/opencv_ffmpeg.dll
用迅雷下载，下载好的文件放入
source
目录下的
.cache
文件夹中
重命名下载好的文件，替换原来的
最后打开cmake重新编译一遍即可
卡在类似的
Download: xxxx
也是用同样方法解决。
