GStreamer with QT6

[Joe von Habsburg]

@JoeCFD said in GStreamer with QT6:

@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

There is only C:/gstreamer/1.0/msvc_x86_64/bin/pkg-config.exe

[JoeCFD]

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_PATH

Do 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

[JoeCFD]

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

it can be there. Try to reinstall it in different ways.

[Joe von Habsburg]

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-server

and 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

":" is missing in the picture.

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

[Joe von Habsburg]

@anonymus982493

Could not work on me :/

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

open 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.
