Original commit message from CVS:
* configure.ac:
* ext/ladspa/Makefile.am:
Link the ladspa plugin with -ldl. It's needed for dlopen() and friends
for loading the ladspa plugins and previously was linked in by
gmodule. Fixes bug #543848.
Original commit message from CVS:
* ext/ladspa/gstladspa.c: (gst_ladspa_base_init),
(gst_ladspa_class_init), (ladspa_describe_plugin), (plugin_init):
Don't use GST_BOILERPLATE as the stuff generated from it is not used
anyway and can't be used.
Store the class struct of the correct type in parent_class.
Pass the LADSPA_Descriptor as class_data to the class_init function
as preparation for the time, when we can add pad templates and friends
in class_init and add a FIXME for that.
Don't use a custom hash table for passing the LADSPA_Descriptors to
base_init but use g_type_set_qdata and g_type_get_qdata.
Original commit message from CVS:
* ext/ladspa/gstsignalprocessor.c:
(gst_signal_processor_class_add_pad_template):
Don't unref the pad template after adding it.
gst_element_class_add_pad_template takes ownership of it.

Fix 'xyz may be used uninitialized' compiler warnings caused
by broken g_assert_not_reached() macro in GLib-2.15.x and don't
abort() in any case but properly report the error.

* ext/ladspa/gstsignalprocessor.c (gst_signal_processor_fixate)
(gst_signal_processor_ouija_caps, gst_signal_processor_prepare):
Remove fixate/ouija stuff, thankfully, due to the new
part-negotiation.txt pull-mode negotiation scheme.
(gst_signal_processor_setcaps_pull)
(gst_signal_processor_setcaps): Implement upstream set_caps pull
proxying for pull mode. Now this works: ladspa-sine-fcac !
audioconvert ! alsasink.

* ext/ladspa/gstsignalprocessor.c
(gst_signal_processor_ouija_caps): Move around in the source
file...
(gst_signal_processor_prepare, gst_signal_processor_do_pulls):
Call ouija_caps in prepare() instead of do_pulls(), a bit earlier.
This allows us to have caps when we do the pad_alloc_buffer().
(gst_pad_alloc_buffer_and_set_caps): Use self->caps instead of the
pad caps, which might not be set yet.

* ext/ladspa/gstsignalprocessor.c:
(gst_signal_processor_add_pad_from_template)
(gst_signal_processor_fixate): Add a fixate function, to assist in
pathological ladspa-sine-fcac ! fakesink can-activate-pull=true
cases.
(gst_signal_processor_prepare, gst_signal_processor_process): Add
nframes args so that getrange can tell ladspa how many frames to
process.
(gst_signal_processor_ouija_caps): setcaps needs to be called
before processing, which normally happens when chaining a buffer
to a pad. However in getrange mode with no sinks we need to check
explicitly for this condition, guess some caps to use, and use
those to setcaps(). Hence this mystical function.
(gst_signal_processor_do_pulls): Pull in bytes, not samples.
Divine the caps if necessary.
(gst_signal_processor_getrange): Interpret the length as bytes,
not samples.
(gst_signal_processor_chain): nframes=G_MAXUINT, will be limited
by incoming buffer sizes.
Original commit message from CVS:
* ext/ladspa/gstsignalprocessor.c: (gst_signal_processor_setcaps),
(gst_signal_processor_event):
Reset flow_state back to _OK after a flush stop so that we exit our
error state after the flush. Fixes#374213
Original commit message from CVS:
* ext/ladspa/gstladspa.c: (gst_ladspa_base_init):
Convert ' ' into '_'. Try to keep as many characters in the padtemplate
names as possible.
Original commit message from CVS:
* ext/ladspa/gstsignalprocessor.c: (gst_signal_processor_flush),
(gst_signal_processor_do_pushes):
A push() gives away our refcount so we should not use the buffer on the
pen anymore.
Original commit message from CVS:
2006-08-04 Andy Wingo <wingo@pobox.com>
* ext/ladspa/gstsignalprocessor.h: Add infrastructure for storing
whether a processor can work in place or not, and for keeping
track of its state. Change the FlowReturn instance variable from
"state" to "flow_state", all callers changed.
* ext/ladspa/gstsignalprocessor.c (gst_signal_processor_setup)
(gst_signal_processor_start, gst_signal_processor_stop)
(gst_signal_processor_cleanup): New functions to manage the
processor's state.
(gst_signal_processor_setcaps): start() as well as setup() here.
(gst_signal_processor_prepare): Respect CAN_PROCESS_IN_PLACE.
(gst_signal_processor_change_state): Stop and cleanup the
processor as we go to NULL.
* ext/ladspa/gstladspa.c (gst_ladspa_base_init): Reuse buffers if
INPLACE_BROKEN is not set.
* ext/ladspa/gstsignalprocessor.c (gst_signal_processor_prepare):
Do the alloc_buffer in bytes, not frames.

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.
Original commit message from CVS:
* ext/ladspa/gstsignalprocessor.c: (gst_signal_processor_setcaps),
(gst_signal_processor_process):
don't query buffer-frames from caps, add lots of debug-log,
try fix for assert (#349189)
Original commit message from CVS:
* ext/ladspa/gstsignalprocessor.c: (gst_signal_processor_event),
(gst_signal_processor_process):
Fix compilation of LADPSA. It doesn't seem to work, and isn't
enabled for the build, but it helps me win the feature-count
competitions ooh yeah.
Original commit message from CVS:
2005-10-07 Andy Wingo <wingo@pobox.com>
* ext/raw1394/gstdv1394src.c: Make interruptible, so it won't
block forever in a read().
Original commit message from CVS:

* Updates for two-arg init from GST_BOILERPLATE.
* ext/ladspa/gstsignalprocessor.c (gst_signal_processor_init): Use
the second arg for the class, because G_OBJECT_GET_CLASS (self)
returns the wrong thing.
(gst_signal_processor_add_pad_from_template): Make pads of the
right type.
* ext/ladspa/gstladspa.c (gst_ladspa_class_get_param_spec): Make
writable param specs G_PARAM_CONSTRUCT so default values work.
(gst_ladspa_init): Use the second arg for the class.

output the ladspa makefile.

second batch :
remove ',' at end of enums as they could confuse older gcc, foreign compilers (forte) and gtk-doc
(in gst-plugins/ext/ this time)
