Ffmpeg nlmeans example

In the original NL-means algorithm the base was a single pixel (Bx=0 and By=0). Using blocks larger than a single pixel will sacrifice some quality for speed. Note that Sx must be greater than or equal to Bx and Sy must be greater than or equal to By. It is recommended that Sx/Sy be larger than Bx/By. bool ms = falseNov 13, 2020 · 准备工具: msys64: msys64 建议下载exe安装版本,直接下载最新版,不要去下载免安装版本,且不是最新版本,后面会说明原因 我安装的目录是D:\msys64,后面为以这个目录为准. vs2019安装完成后,使用x86编译,找到vs的x86 Native Tools 打开…我此次编译32位版本的. msys,在这里运行cl ...
