Original commit message from CVS:
Patch by: Lutz Mueller <lutz@topfrose.de>
* gst/real/Makefile.am:
* gst/real/gstreal.c: (plugin_init):
* gst/real/gstrealaudiodec.c: (gst_real_audio_dec_chain),
(gst_real_audio_dec_setcaps), (gst_real_audio_dec_init),
(gst_real_audio_dec_base_init), (gst_real_audio_dec_change_state),
(gst_real_audio_dec_finalize), (gst_real_audio_dec_set_property),
(gst_real_audio_dec_get_property), (gst_real_audio_dec_class_init):
* gst/real/gstrealaudiodec.h:
Added RealAudio wrapper elementfactory.
Modified structures so it can also work on x86_64 using the
adequate .so .
