qt + gstreamer 运行环境编译（linux下）

Here it is a "hello world" gstreamer application which simply plays the video stream coming from the videotestsrc.

#include
#include
 
int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);
 
gst_init (NULL,NULL);
 
GstElement *bin = gst_pipeline_new ("pipeline");
g_assert(bin);
 
GstElement *testSrc = gst_element_factory_make("videotestsrc", "source");
g_assert(testSrc);
 
GstElement *videoOut = gst_element_factory_make("autovideosink", "video out");
g_assert(videoOut);
 
gst_bin_add_many(GST_BIN(bin), testSrc, videoOut, NULL);
gst_element_link_many(testSrc, videoOut, NULL);
 
gst_element_set_state(GST_ELEMENT(bin), GST_STATE_PLAYING);
 
return a.exec();
}

Here tit is the project file needed to compile the code above

QT += core
QT -= gui
 
TARGET = untitled
CONFIG += console
CONFIG -= app_bundle
 
TEMPLATE = app
 
SOURCES += main.cpp
 
unix {
CONFIG += link_pkgconfig
PKGCONFIG += gstreamer-0.10
}
