GStreamer with QT6

[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

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 ?

[JoeCFD]

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.

Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE)

Reason given by package: The command

Im facing error while configure that pkgconfig is not there in gstreamer can you share the which gstreamer i need to use to get the pkgconfig for windows

[Christian Ehrlicher]

Install your stuff in paths without spaces

[Bala_suresh]

im getting error from gstreamer pkgcofig not in qt

[Christian Ehrlicher]

But there are still spaces in there...

[Bala_suresh]

@Christian-Ehrlicher your talking about environment paths right

[Christian Ehrlicher]

@Bala_suresh said in GStreamer with QT6:

C:/Program Files/gstreamer/1.0/msvc_x86_64/include

isn't that obvious enough?

[Bala_suresh]

@Christian-Ehrlicher this is my path

[Christian Ehrlicher]

I'm giving up...
Run the pkg-config command on the command line and you will see I would guess.

[Bala_suresh]

can you share the gstreamer link or pkgconfig exe
