I received this error while building opencv:

make[2]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/build.make:128: modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_ffmpeg.cpp.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:8811: modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2
make: *** [Makefile:163: all] Error 2

It was after entering “make -j4” in the command line.

There were a few red marked words before the code up here. Let me know if you would like to take a look.

I tried installing MM on tinker board and installed face recognition module but it fails at the point when facial recognition(using opencv) starts, suddenly shuts down the system(i.e tinker board)
Cause of this issue is yet not identified.
Any help on this will be appreciated

UPDATE: This, like some other issues I was running into was actually caused by the application freezing when it could not load ‘css/custom.css’.

This is because the .gitignore does not track custom.css and I, like many others, edit my code on my desktop and then push the changes via git to my RPi.
