#include <gst/gst.h>
#include <stdio.h>
  
int main(int argc, char *argv[])
{
	GstElement *pipeline;
	GstBus *bus;
	GstMessage *msg;

	/* Initialize GStreamer */
	gst_init(&argc, &argv);

	/* Build the pipeline */
	pipeline = gst_parse_launch("playbin uri=https://gstreamer.freedesktop.org/media/gst-integration-testsuite/defaults/webm/vorbis_vp8.0.webm", NULL);
	printf("---%p\n", pipeline);

	/* Start playing */
	gst_element_set_state(pipeline, GST_STATE_PLAYING);

	/* Wait until error or EOS */
	bus = gst_element_get_bus(pipeline);
	msg = gst_bus_timed_pop_filtered(bus, GST_CLOCK_TIME_NONE, GST_MESSAGE_ERROR | GST_MESSAGE_EOS);

	/* Free resources */
	if (msg != NULL)
		gst_message_unref(msg);
	gst_object_unref(bus);
	gst_element_set_state(pipeline, GST_STATE_NULL);
	gst_object_unref(pipeline);
	return 0;
