Help with QtGStreamer, undefined reference to QGst::init

[JackCity63]

I am having some trouble with implementing QtGStreamer with QT. I have downloaded the source code for QtGStreamer and put it in "C:/qt-gstreamer-1.2.0" I am trying to run one of the examples that was provided, the player example.

Here is my code:

player.pro


TEMPLATE = app
TARGET = player

CONFIG += silent

CONFIG += pkgconfig

contains(QT_VERSION, ^4\\..*) {
PKGCONFIG += QtGStreamer-1.0 QtGStreamerUi-1.0 QtGlib-2.0 QtGStreamerUtils-1.0
QT += widgets
}
contains(QT_VERSION, ^5\\..*) {
PKGCONFIG += Qt5GStreamer-1.0 Qt5GStreamerUi-1.0 Qt5Glib-2.0 Qt5GStreamerUtils-1.0 Qt5GStreamerQuick-1.0
QT += widgets \
enginio
}

QMAKE_CXXFLAGS += -std=c++0x

DEFINES += QT_NO_KEYWORDS

HEADERS += mediaapp.h player.h
SOURCES += main.cpp mediaapp.cpp player.cpp

INCLUDEPATH += C:\qt-gstreamer-1.2.0\src \
C:\boost_1_58_0

main.cpp


#include "mediaapp.h"
#include <QApplication>
#include <QGst/Init>


int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QGst::init(&argc, &argv);



MediaApp media;
media.show();

if (argc == 2) {
media.openFile(argv[1]);
}

return app.exec();
}


There are other cpp files in the example, but they are all giving the same type of error. When I try to build the project, I get the error "undefined reference to 'QGst::init'" I cannot figure out what I am doing wrong. I think there needs to be something changed in the .pro file, but I couldn't find anything telling me what to do to fix it. I am on Windows, using with mingw compiler.

Is your application getting linked against QtGstreamer libraries? I don't think pkgconfig works on Windows so your project file is incomplete for this platform.
