The reason for this error is vlc uses pkg-config to detect opencv and apparently opencv recently removed pkg-config support from the default 4.x builds, as they don't see it as very useful. https://github.com/opencv/opencv/issues/13154 It looks like when opencv 4 is built it also advertises opencv4 instead of opencv, so it looks like some minort retooling of the vlc configure is needed regardless of whether they keep pkg-config. https://github.com/opencv/opencv/commit/c9b2cedebdcd3e1472eba4609f87e78cf4af17df For myself, I just disabled the opencv use flag for vlc.
https://trac.videolan.org/vlc/ticket/22016#no1 opencv4 apparently also requires c++11 support. IDK if vlc is close to c++11 or not.

If the following line is also added: -DOPENCV_PC_FILE_NAME=opencv.pc it restores the filename to what is expected.
(In reply to Attila Tóth from comment #6) > If the following line is also added: > -DOPENCV_PC_FILE_NAME=opencv.pc > it restores the filename to what is expected. That configure option was ignored when exporting it in the MYCMAKEARGS env variable. It seems to be hardcoded in cmake/OpenCVGenPkgconfig.cmake with the following: > if(INSTALL_TO_MANGLED_PATHS) > ocv_update(OPENCV_PC_FILE_NAME "opencv-${OPENCV_VERSION}.pc") > else() > ocv_update(OPENCV_PC_FILE_NAME opencv4.pc) > endif() Changing "opencv4.pc" to "opencv.pc" worked for me.

I have added the following sed -i -e's/opencv > 2.0/opencv4 > 2.0/' configure.ac to src_prepare. Now vlc discovers opencv BUT later on it compiles video_output/glx.c with gcc but not g++ This includes In file included from /usr/include/opencv4/opencv2/core/cvdef.h:10, from /usr/include/opencv4/opencv2/core/types_c.h:82, from /usr/include/opencv4/opencv2/core/core_c.h:48, from video_filter/opencv_wrapper.c:42: /usr/include/x86_64-pc-linux-gnu/opencv4/opencv2/core/cvdef.h:694:4: error: #error "OpenCV 4.x+ requires enabled C++11 support" 694 | # error "OpenCV 4.x+ requires enabled C++11 support" and, as the gcc doesn't have the option -std=c++11, I don't see a possibility to fix this except as compiling any file which includes opencv2/core/cvdef.h with g++ but that causes further problems which have to be fixed. I wonder if anybody was able to compile vlc (vlc-3.0.9999) with opencv-4.1.2 installed.

I got an info from OpenCV upstream that they won't support compiling as C code any more. So any source files which use OpenCV would have to be rewritten to be compilable with C++ compiler.
*** Bug 702984 has been marked as a duplicate of this bug. ***
I have the same problem here. Maybe it's missing a dependency in vlc-3.0.8 that requires opencv < 4.
