need to build gstreamer, the version in the cmake stays 1.14 even i have manually changed the path to .so files of gstreamer Error : Make Error in modules/videoio/CMakeLists.txt: Imported target “ocv.3rdparty.gstreamer” includes non-existent path ``` "/usr/include/gstreamer-1.0" ``` in its INTERFACE\_INCLUDE\_DIRECTORIES. Possible reasons include: - The path was deleted, renamed, or moved to another location. - An install or uninstall procedure did not complete successfully. - The installation package was faulty and references files it does not provide. ---

clear the build directory, or at least `CMakeCache.txt` ---

i tried that , then it’s not detecting gstreamer at all ---

have you successfully built gstreamer, or installed a package of gstreamer that contains development files (libraries, headers)? ---

that isn’t gstreamer, that’s ffmpeg you need to build ffmpeg differently. see here, same error that says “recompile with -fPIC”, and same resolution: [Error: ‘AVStream’ {aka ‘struct AVStream’} has no member named ‘codec’ - #8 by crackwitz](https://forum.opencv.org/t/error-avstream-aka-struct-avstream-has-no-member-named-codec/3506/8) ---

What i noticed is the gstreamer is not able to build with libav , is this also an issue due to ffmpeg? ---

libav\* (libavformat, libavcodec, …) are the libraries of ffmpeg. “ffmpeg”, in the context of OpenCV, means “ffmpeg libraries”. gstreamer does not depend on ffmpeg. ffmpeg does not depend on gstreamer. OpenCV can use either or both. you did not show issues with building gstreamer itself. you don’t need to build gstreamer. you showed issues with building OpenCV, where ffmpeg and/or gstreamer were the issue. you need to provide specific information, i.e. precisely what you do, and all log outputs. ---

Apologies for the confusion. I am totally new to this. When i did the Gstreamer installation , i got a similar error regarding libgstav. So i disabled that certain sub-project and installed it. After that i tried install OpenCV with that Gstreamer support. At that time i got the error i mentioned above. So i thought that was due to the disabled module. As you shared above link which confirmed it’s an issue related to FFmpeg which i didn’t needed, so i removed it in cmake.list and builded OpenCV. And that helped me . Let me know if anything need to be clarified. Thanks again. ---

I encountered the same issue. The error message indicate the real problem. The header file directory for gstreamer-1.0 does not exist. If you build gstreamer-1.0 by yourself and install it somewhere, let’s say ~/\_install, then you should copy the header like this: sudo cp ~/\_install/include/gstreamer-1.0 /user/include/
