Original commit message from CVS: * gst-libs/gst/rtp/gstbasertpdepayload.c: (gst_base_rtp_depayload_setcaps), (gst_base_rtp_depayload_chain), (gst_base_rtp_depayload_set_gst_timestamp), (gst_base_rtp_depayload_change_state): * gst-libs/gst/rtp/gstbasertpdepayload.h: Add some more G_LIKELY Fail when the setcaps function was not called. * gst-libs/gst/rtp/gstbasertppayload.c: (gst_basertppayload_set_outcaps): Propagate return value of setcaps.
