c++ - 使用 Gstreamer1.0 GTK+3.0 显示视频

Question

我无法在 GtkWidget 中正确插入视频。告诉我我做错了什么？视频在一个新窗口中打开，而不是在我发送的那个窗口中。视频应在该窗口的背景中打开。

Libvlc 库的显示方式相同，可能问题出在操作系统上，我在 Ubuntu 17.10 上编写

using namespace std;


GstElement *pipeline, *src, *sink, *b;

int main(int argc, char *argv[]) {
cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!

GtkWidget *window;
 gtk_init (&argc, &argv);

  window = gtk_window_new (GTK_WINDOW_TOPLEVEL);

  //gtk_container_border_width (GTK_CONTAINER (window), 10);

      gtk_widget_show (window);

      gtk_main ();
