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?

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:\n\n\nonly set \"WITH_GSTREAMER\" option to True, \"WITH_GSTREAMER_0_10\" MUST BE FALSE\nadd new entry \"GSTREAMER_DIR\"=(path to gstreamer)\n for me it was \"C:/gstreamer/1.0/x86_64\"\nI found this solution here\n\n\nMy OpenCV version: 3.4.3",

I had the same problem.\n\ngstreamer-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.\n\nThe 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).\n\nTherefore, the following command should be used to install the missing dependencies:\n\nsudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev\n\n\nRepeat the cmake command, possibly purging the contents of the build directory beforehand.",
