Original commit message from CVS: * ext/faad/gstfaad.c: (gst_faad_base_init), (gst_faad_class_init), (gst_faad_init), (gst_faad_srcgetcaps), (gst_faad_event), (gst_faad_chain), (gst_faad_change_state): * ext/faad/gstfaad.h: Do some timestamp smoothing (matroskademux apparently sends multiple buffers in a row with the same timestamp); fix duration on outgoing buffers; fix change state function; use GST_DEBUG_FUNCPTR for pad functions.
