Original commit message from CVS:
2006-08-01  Andy Wingo  <wingo@pobox.com>

* ext/ladspa/gstsignalprocessor.c (gst_signal_processor_init): No
more default sample rate, although we never check that the sample
rate actually gets set. Something for the future.
(gst_signal_processor_setcaps): Some refcount fixes, flow fixes.
(gst_signal_processor_event): Refcount fixen.
(gst_signal_processor_process): Pull the number of frames to
process from the sizes of the buffers in the input pens.
(gst_signal_processor_pen_buffer): Remove an incorrect FIXME :)
(gst_signal_processor_do_pulls): Add an nframes argument, and use
it instead of buffer_frames.
(gst_signal_processor_getrange): Refcount fixen, pass nframes on
to do_pulls.
(gst_signal_processor_chain)
(gst_signal_processor_sink_activate_push)
(gst_signal_processor_src_activate_pull):  Refcount fixen.

* ext/ladspa/gstsignalprocessor.h: No more buffer_frames, yay.
