Initializing gstreamer crashes my Qt Application
I am trying to integrate "gstreamer":http://www.gstreamer.freedesktop.org/ into my application as suggested "here ":http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstvideooverlay.html#GstVideoOverlay ,the problem is that the application crashes with the follwing application output:
The program has unexpectedly finished.
A section of my main function looks like this:
int main(int argc, char *argv)
if (!g_thread_supported ()) g_thread_init (NULL); gst_init (&argc, &argv);//The application crashes here QApplication app(argc, argv); app.connect(&app, SIGNAL(lastWindowClosed()), &app, SLOT(quit ())); // prepare the pipeline GstElement *pipeline = gst_pipeline_new ("xvoverlay"); ................................... // prepare the ui QWidget window; window.resize(320, 240); window.show(); WId xwinid = window.winId(); gst_video_overlay_set_window_handle (GST_VIDEO_OVERLAY (sink), guintptr (xwinid)); run the pipeline int ret = app.exec(); window.hide(); gst_element_set_state (pipeline, GST_STATE_NULL); gst_object_unref (pipeline); return ret;
I would appreciate it if somebody helped with the issue.Gstreamer is working within visual studio environment (console and creating its own display window) .I want that window to be a Qt widget within my app.
I am working with Qt 4.8.6 /vs 2010/win x86 if this is helpful
Thank you for your time.
If you want to mix both, you should have a look at QtGStreamer, it provides everything you need to mix Qt and gstreamer
