Original commit message from CVS:
* ext/x264/gstx264enc.c: (gst_x264_enc_header_buf),
(gst_x264_enc_sink_event), (gst_x264_enc_chain),
(gst_x264_enc_encode_frame):
Try harder not to crash when we get an EOS event but haven't set
up the encoder yet (as may happen when upstream errors out with
not-negotiated, for example). Also, always push the EOS event
downstream.
