GStreamer with QT6

@JoeCFD said in GStreamer with QT6:
I think you did not set pkg configure path. If you do not know how to set it, find the pkg files in gstreamer installation and add all the libs inside to your project.
PKG_CONFIG_PATH=C:/gstreamer/1.0/msvc_x86_64/bin/pkgconfig:$PKG_CONFIG_PATH
@Joe-von-Habsburg pkg config path is under gstreamer lib dir.
For example in Linux
/opt/thirdParties/gstreamer/lib/pkgconfig
Maybe it is different in Windows
and pkg-config.exe has to be in system path of Windows. -

add C:/gstreamer/1.0/msvc_x86_64/bin to PATH on Windows. This enables you to run pkg-config.exe and use pkg-config. Nice that gstreamer includes it for you.
go to C:/gstreamer/1.0/msvc_x86_64/lib to find dir pkgconfig. Add C:/gstreamer/1.0/msvc_x86_64/lib/pkgconfig to PKG_CONFIG_PATHDo not forget to add gstreamer plugin path as well in your env. Otherwise, you can not run your gstreamer app.

C:/gstreamer/1.0/msvc_x86_64/bin to PATH on Window
it already exists
@JoeCFD said in GStreamer with QT6:
C:/gstreamer/1.0/msvc_x86_64/lib to find dir pkgconfig
there is no pkg lib
@JoeCFD said in GStreamer with QT6:
C:/gstreamer/1.0/msvc_x86_64/lib/pkgconfig
its not here.
I have only pkg-config exe in C:/gstreamer/1.0/msvc_x86_64/bin/pkg-config.exe

If it does not exist, you are unable to use it. I can check it out later for you in my home Windows.

@JoeCFD thank you so much, I will wait and research new solutions

@Joe-von-Habsburg I edited my post. You need to figure out how to set pkg path on Windows.
On linux:
export PKG_CONFIG_PATH=/opt/thirdParties/gstreamer/lib/pkgconfig:$PKG_CONFIG_PATHit is easier to use pkg config to add packages into a project because all dependencies are taken care of. But you can add all libs manually as well.
I download files with msys :
pacman -S mingw-w64-x86_64-gstreamer mingw-w64-x86_64-gst-plugins-base \ mingw-w64-x86_64-gst-plugins-good mingw-w64-x86_64-gst-plugins-bad \ mingw-w64-x86_64-gst-plugins-ugly mingw-w64-x86_64-gst-libav \ mingw-w64-x86_64-gst-rtsp-serverand I copy the pkgconfig to lib like that
and gsreamer-1.0.pc and gsteamer-video-1.0.pc exist
cmake like that :
PKG_CONFIG_PATH=C:/gstreamer/1.0/msvc_x86_64/lib/pkgconfig:$PKG_CONFIG_PATH find_package( PkgConfig REQUIRED ) pkg_search_module( GSTREAMER REQUIRED IMPORTED_TARGET gstreamer-1.0) pkg_search_module( GSTREAMER-VIDEO REQUIRED IMPORTED_TARGET gstreamer-video-1.0)but its not work

I forgot about it and added it. the code shows it as added. but nothing happened. i keep getting the error. i'm sure the solution is very simple in linux. i wish it could be the same in windows.

hey, the problem is that you need to write it like this:
set(PKG_CONFIG_PATH=C:/gstreamer/1.0/msvc_x86_64/lib/pkgconfig:$PKG_CONFIG_PATH)
this way it should work, I had the same problem last week -

Where do you install gstreamer and where do you install pkgconfig folder in lib ?

https://stackoverflow.com/questions/10810279/finding-libraries-using-pkg-config-in-windowsopen one of the pc files and check if the prefix is correct.
The installed pkg config path is basically fixed under lib. Do not try to change it.
