[gst-devel] Catching EOS from a chain-based filter

[in7y118 at public.uni-hamburg.de]

You can try to handle events yourself. If you put the following line in your 
_init function:
  GST_FLAG_SET (this, GST_ELEMENT_EVENT_AWARE);
events will be sent to your chainfunction. You will have to handle all the 
elements then. This is pretty easy though, the basic way to do this is to just 
do (from the top of my head):
  if (GST_IS_EVENT (buffer)) {
    gst_pad_event_default (pad, GST_EVENT (event));
    return;
  }
  /* normal chain function */
I hope that was what you were looking for :)
