From 71b95f01453faf880ec957835acb967f71594241 Mon Sep 17 00:00:00 2001 From: Steve Baker Date: Sat, 20 Apr 2002 13:57:00 +0000 Subject: A fairly large reworking of the ladspa _get, _chain and _loop funcs. highlights are: Original commit message from CVS: A fairly large reworking of the ladspa _get, _chain and _loop funcs. highlights are: - pad names are now g_strcanonised - in all cases possible, src and sink buffers are shared - all ladspa properties are exposed as dparams and element properties - the buffers are now processed in dparam driven loops - timestamps on buffers should be correct - misc fixes It has been minimally tested - the following pipeline works for me: gst-launch ladspa_sine_fcac Frequency=440.0 Amplitude=1.0 name=fcac1 ladspa_sine_fcac Frequency=450.0 Amplitude=1.0 name=fcac2 ladspa_freeverb3 Wet-Level=0.5 name=free float2int name=f2i fcac1.Output!free.Input--Left- free.Output--Left-!f2i.sink%d fcac2.Output!free.Input--Right- free.Output--Right-!f2i.sink%d f2i.src!sink osssink --- ext/ladspa/gstladspa.c | 640 ++++++++++++++++++++++++++++++------------------- 1 file changed, 399 insertions(+), 241 deletions(-) (limited to 'ext/ladspa/gstladspa.c') diff --git a/ext/ladspa/gstladspa.c b/ext/ladspa/gstladspa.c index 65c4c549..dd1f9432 100644 --- a/ext/ladspa/gstladspa.c +++ b/ext/ladspa/gstladspa.c @@ -20,59 +20,49 @@ #include #include +#include #include "gstladspa.h" #include "ladspa.h" /* main ladspa sdk include file */ #include "utils.h" /* ladspa sdk utility functions */ -static GstPadTemplate* -ladspa_src_factory (void) -{ - return - gst_pad_template_new ( - "src", - GST_PAD_SRC, - GST_PAD_ALWAYS, - gst_caps_new ( +GST_PAD_TEMPLATE_FACTORY (ladspa_sink_factory, + "sink", + GST_PAD_SINK, + GST_PAD_REQUEST, + GST_CAPS_NEW ( + "ladspa_sink", + "audio/raw", + "rate", GST_PROPS_INT_RANGE (4000, 96000), + "format", GST_PROPS_STRING ("float"), + "layout", GST_PROPS_STRING ("gfloat"), + "intercept", GST_PROPS_FLOAT(0.0), + "slope", GST_PROPS_FLOAT(1.0), + "channels", GST_PROPS_INT (1) + ) +);
