I'm planning to use Opencv(3.4) in C++ (Qt creator) in Raspberry pi 3. i have tried building using Cmake GUI. unfortunately ffmpeg do not build with opencv.
Note: i don't want just Opencv to be built, i have done that already. it works fine.
i am looking for someone who can build Opencv WITH ffmpeg for C++ (NOT PYTHON)
if you want i'll give access to my device (rpi 3)
