Compiling Opencv with Gstreamer, cmake not finding GStreamer

The below worked for me if you are developing just a Gstreamer applicaiton

# GStreamer CMake building
cmake_minimum_required(VERSION 3.3)
project(GStreamerHello)

set(PKG_CONFIG_USE_CMAKE_PREFIX_PATH ON)
find_package(PkgConfig REQUIRED)
if ( NOT (PKGCONFIG_FOUND))
      message(FATAL_ERROR "Please Install PPkgConfig: CMake will Exit")
endif()
pkg_check_modules(GST REQUIRED gstreamer-1.0>=1.8)
if ( NOT (GST_FOUND))
      message(FATAL_ERROR "Please Install Gstreamer Dev: CMake will Exit")
endif()
set(ENV{PKG_CONFIG_PATH})

include_directories("${GST_INCLUDE_DIRS}")

link_libraries(${GST_LIBRARIES})

add_executable(gstreamerSrvc  src/hello_gstreamer.cc)
add_dependencies(gstreamerSrvc vsphere_header )
target_link_libraries(gstreamerSrvc ${GST_LIBRARIES}  )

Note - If you need a dev docker for GStreamer it is below; and for your question it has the parts of compiling with OpenCV as well; More details at https://medium.com/techlogs/compiling-opencv-for-cuda-for-yolo-and-other-cnn-libraries-9ce427c00ff8

I had the same problem.

gstreamer-base corresponds to libgstbase-1.0.so (or libgstbase-0.10.so), found in package libgstreamer1.0-0 (or libgstreamer0.10-0, as the case may be). Below, we install the '-dev' package.

The other libraries (libgst-video, libgst-app, libgst-riff, libgst-pbutils) I found in package libgstreamer-plugins-base1.0-dev (again, substitute the version you wish to use, either v0.1, or v1.0).

Therefore, the following command should be used to install the missing dependencies:

sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev

Repeat the cmake command, possibly purging the contents of the build directory beforehand.

On Windows there is no "sudo apt install..." I also had all the paths set right in my PATH environment variable, and still had the same problem. I've got this working after setting following CMake Options:

1. only set "WITH_GSTREAMER" option to True, "WITH_GSTREAMER_0_10" MUST BE FALSE
2. add new entry "GSTREAMER_DIR"=(path to gstreamer) for me it was "C:/gstreamer/1.0/x86_64" I found this solution here

My OpenCV version: 3.4.3
