Original commit message from CVS: * ext/a52dec/gsta52dec.c: (gst_a52dec_init), (gst_a52dec_push), (gst_a52dec_sink_event), (gst_a52dec_handle_frame), (gst_a52dec_chain), (gst_a52dec_change_state): * ext/a52dec/gsta52dec.h: Mark discont on outgoing buffers after receiving a DISCONT buffer or when we have a decoding error. We don't need to clear the cache when we receive a NEWSEGMENT event. Clear buffer cache in DISCONT. Add beginnings of GstSegment handling.
