Compiling Opencv with Gstreamer, cmake not finding GStreamer

Question

I want to build opencv with GStreamer support.

I built the GStreamer from source (version 1.8.1) following this guide: http://kacianka.at/?p=145 I have 'gstreamer_build' folder at my home directory and it contains 'bin' folder with these:

gst-device-monitor-1.0 gst-discoverer-1.0 gst-inspect-1.0 gst-launch-1.0 gst-play-1.0 gst-stats-1.0 gst-typefind-1.0 orc-bugreport orcc

I have this path added to my environment variable PATH.

When I use cmake like:

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules -D BUILD_opencv_python3=ON -D WITH_GSTREAMER=ON -D WITH_FFMPEG=OFF ..

I get the following output clearly indicating that gstreamer is not found:

-- checking for module 'gstreamer-base-1.0'
--   package 'gstreamer-base-1.0' not found
-- checking for module 'gstreamer-video-1.0'
--   package 'gstreamer-video-1.0' not found
-- checking for module 'gstreamer-app-1.0'

--   package 'gstreamer-riff-0.10' not found
-- checking for module 'gstreamer-pbutils-0.10'
--   package 'gstreamer-pbutils-0.10' not found

and this:

Can anyone help me with this?

Answer 1

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.

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

Answer 3

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
