Original commit message from CVS: * configure.ac: Added mpegaudioparse * ext/lame/gstlame.c: (gst_lame_src_getcaps), (gst_lame_src_setcaps), (gst_lame_sink_setcaps), (gst_lame_sink_event), (gst_lame_chain): Some cleanups. Fix memleak. * gst/mpegaudioparse/gstmpegaudioparse.c: (gst_mp3parse_class_init), (gst_mp3parse_init), (gst_mp3parse_chain), (gst_mp3parse_change_state): * gst/mpegaudioparse/gstmpegaudioparse.h: Ported mpegaudioparse
