It sems like a deadlock because you try to shut down the pipeline from a streaming thread. </blockquote><div> No, In my application:- </div>{ .  /* created elements */ .. ..   bus = gst_pipeline_get_bus (GST_PIPELINE (pipeline));   gst_bus_add_watch (bus, bus_call, loop);   gst_object_unref (bus);        /* put all elements in a bin */   gst_bin_add_many (GST_BIN (pipeline),             source, encoder, sink, NULL);   gst_element_link (source, encoder);   gst_element_link (encoder, sink);       /* Now set to playing and iterate. */   g_print ("APP: Setting to PLAYING\n");   gst_element_set_state (pipeline, GST_STATE_PLAYING);   g_print ("APP: Running\n");   g_main_loop_run (loop);       /* clean up nicely */   g_print ("APP: Returned, stopping playback\n");   gst_element_set_state (pipeline, GST_STATE_NULL);   g_print ("APP: Deleting pipeline\n");   gst_object_unref (GST_OBJECT (pipeline));   return 0; } Here the bus is already unref. The application hangs at last line ==> gst_object_unref(GST_OBJECT(pipeline)) <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">   As mentionned before, seeing your code would be much easier to spot the error.</blockquote><div> Thanks, --vinayak </div></div>
