Hi, I´m having problems trying to change the pipeline state. Please find below a snippet of the code: gst_element_set_state (vid->pipeline, GST_STATE_READY); and this is the error message I am getting: (<unknown>:10599): GStreamer-CRITICAL **: gst_element_set_state: assertion `GST_IS_ELEMENT (element)' failed Can someone shed some light on what could be causing this? Thanks! Sebastián
