为其他人编译 OpenCV + Gstreamer

Question

I created a project which uses OpenCV and Gstreamer (receiving udp stream), It's working perfectly fine if open with Visual Studio (Run button). But after compiling Release x64 MT and trying I not only need to throw a whole lot of GStreamer.dll files to open my app but even after it opens successfully when It comes to opening a stream I get a warning, because of which my program is not working (Capture return false)

[ WARN:0] global F:\Code\opencv_4.5.1\opencv-4.5.1\modules\videoio\src\cap_gstreamer.cpp (734) cv::GStreamerCapture::open OpenCV | GStreamer warning: Error opening bin: no element "udpsrc"
[ WARN:0] global F:\Code\opencv_4.5.1\opencv-4.5.1\modules\videoio\src\cap_gstreamer.cpp (501) cv::GStreamerCapture::isPipelinePlaying OpenCV | GStreamer warning: GStreamer: pipeline have not been created

It seems like it can't find something. My question is:

How to compile my project so any other Windows computer could open it and find all needed files? (bonus points for hiding.dlls)

Thanks

Ok I found out, for some reason you need o move.dll files from GStreamer /bin folder to your application main directory, and in the previous folder copy GStreamer /lib folder

/MyFolder
   /my app
       /*.dll
       /myapp.exe
   /lib

*.dll-s from " \gstreamer\1.0\x86_64\bin " /lib from " \gstreamer\1.0\x86_64 "

A whole lot of files, and it's breaking my directory organization but it's finally working - I someone found out how to fix/improve that, please let me know:wink:
