on which os ?

(windows opencv binaries come with an own prepackaged ffmpeg (i think it’s [this](https://github.com/opencv/opencv_3rdparty/blob/ffmpeg/4.x_20220912/ffmpeg/ffmpeg_version.cmake)), while on linux, etc it will use, what _you_ install locally)

also look at `cv::getBuildInformation()` output, which has a ‘VideoIO’ section

Therefore, the FFmpeg version corresponding to OpenCv4.5.5 is n4.4.2？
