[gst-devel] Creating multiple sinks

[Pavan Kumar Patale]

Hi,

I tried to do that but still i am unable to get the result.  The code is as 
follows.   Could you pls let me know if the usage is right ?

Thanks,
Pavan.

#include<glib.h>
#include<gst/gst.h>
#include<signal.h>
GstElement *pipeline = NULL;
GMainLoop *loop;
void handle()
{
        gst_element_set_state (pipeline, GST_STATE_NULL);
        gst_object_unref (GST_OBJECT (pipeline));
        g_main_loop_quit(loop);
}
