Dear all,
Appart from include the "-e" option to de pipeline to insert a EOS signal
when you perform the ctrl+c, you can try to close properly the file.
/* Now set to playing and iterate. */
g_print ("Setting to PLAYING\n");
gst_element_set_state (pipeline, GST_STATE_PLAYING);
g_print ("Running\n");
:
/* clean up nicely */
gst_element_send_event (pipeline, gst_event_new_eos ());
/* wait for EOS message on the pipeline bus */
msg = gst_bus_timed_pop_filtered (GST_ELEMENT_BUS (pipeline),
GST_MESSAGE_EOS | GST_MESSAGE_ERROR, GST_CLOCK_TIME_NONE);
/* should check if we got an error message here or an eos */
gst_element_set_state (pipeline, GST_STATE_NULL);
g_print ("Deleting pipeline\n");
gst_object_unref (GST_OBJECT (pipeline));
Best,
Angel
