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
