Unsolved "Qt5GStreamer-1.0 development package not found"
-
@jsulm Hi, thank you for replying
Okay, I understand. the errors are link errors.I searched google constantly, but I didn't find how to fix it.
Can you give any idea to sovle it? -
IIRC you need something like:
PKGCONFIG += Qt5GStreamer-1.0 Qt5GLib-2.0
If using QtQuick
PKGCONFIG += Qt5GStreamerQuick-1.0
-
@SGaist Thank you but I tried it already
Now I'm finding any mistake during install qt gstreamer 1.2.0..
-
Silly question then, are you sure that the libraries are built for the right architecture ?
-
@SGaist I Think "yes".
I really don't know why it did it. -
Can you check the link line in the compiler output panel to see if the libraries from QtGstreamer are there ?
-
I checked the compiler output panel, as you said. but I couldn't find the link line.
This is Compile Output

I checked the "init.h". and I'm trying to find 'GStreamer' library.
a part of "QGst/Init.h":
QTGSTREAMER_EXPORT void init(int *argc, char **argv[]); /*! Clean up any resources created by GStreamer in init(). * * It is normally not needed to call this function in a normal application as the resources * will automatically be freed when the program terminates.

Did anybody got the luck to know the reason for:
"Project ERROR: Package Qt5GStreamerQuick-1.0 not found".I have installed: qt-gstreamer-dev package
Not working even after manually adding PKG_CONFIG_LIBDIR:
export PKG_CONFIG_LIBDIR=/home/manojsahu/qt-gstreamer-1.2.0/src/QGst/QtGStreamer-1.0.pc.inI have also added PKGCONFIG alternatively in .pro file like:
PKGCONFIG += Qt5GStreamerQuick-1.0
PKGCONFIG += QtGStreamer-1.0Can anybody help to resolve this error.
I am trying to compile example in below mentioned link:https://github.com/detrout/qt-gstreamer/tree/master/examples/qmlplayer
-
Hi and welcome to devnet,
It's PKG_CONFIG_PATH that you should modify in order to add new paths to search .pc files.
Where are you calling export ?
-
I am calling export PKG_CONFIG_PATH in my example code directory.
-
Are you opening Qt Creator from that terminal ? If not then it won't use the environment variable since it has only been exported in this terminal.
