I think if the  downstream element sends a reconfigure event, the call to
"klass->negotiate (decoder)" from "gst_video_decoder_negotiate" will be done
automatically when the decoder calls any of the following functions:

gst_video_decoder_allocate_output_buffer
gst_video_decoder_allocate_output_frame
gst_video_decoder_finish_frame


But in case this is not valid, here are what you asked:

  if (klass->negotiate)
    ret = klass->negotiate (decoder);

  /* clear GST_PAD_FLAG_NEED_RECONFIGURE if negotiation succeeded */
  if (ret)
    gst_pad_check_reconfigure (decoder->srcpad);

Is it what you thought ?
