Hi,
Are there any gst 1.0 tutorials?

All I found are 0.10 tutorials.

I installed gst 1.0.3 thru a PPA but can't get it to work, simple code that compiles for gst1.0 fails to run with:
(basic:448: GStreamer-CRITICAL **: gst_element_set_state: assertion `GST_IS_ELEMENT (element)' failed

(basic:448: GStreamer-CRITICAL **: gst_element_get_bus: assertion `GST_IS_ELEMENT (element)' failed

(basic:448: GStreamer-CRITICAL **: gst_bus_timed_pop_filtered: assertion `GST_IS_BUS (bus)' failed

(basic:448: GStreamer-CRITICAL **: gst_object_unref: assertion `object != NULL' failed

(basic:448: GStreamer-CRITICAL **: gst_element_set_state: assertion `GST_IS_ELEMENT (element)' failed

(basic:448: GStreamer-CRITICAL **: gst_object_unref: assertion `object != NULL' failed
The official gst1.0 manuals don't give working examples.
